Battery life

To measure the battery life of a laptop, we used two boot scenarios: operating mode and HD video viewing mode. During testing, the power consumption mode was set to “Balanced”, the screen brightness was set to 50% of the maximum, and the wireless module was turned off.

In the mode of operation using the script, the user typing text in a text editor and viewing photos in a slideshow using the Windows Photo Viewer were simulated.

In the video mode (Media Player Classic), a video with a resolution of 1920 × 1080 and a bit rate of 41.1 Mbps (AVC codec) was used. Video playback used hardware GPU acceleration (DXVA).

Considering that we are dealing with a hybrid device that combines both a laptop and a tablet, as well as the fact that the keyboard dock has an additional battery, we tested the Asus Transformer Book T300LA in both laptop and tablet modes.

Load scenario Working hours
Laptop mode Tablet mode
Watching a video 5 hours 48 minutes. 5 hours 39 minutes.
Working with text and viewing photos 12 hours 30 minutes. 12 hours 00 minutes.

As you can see, the battery life of the Asus Transformer Book T300LA is record high. In the video mode, the Asus Transformer Book T300LA laptop and tablet provide more than five and a half hours of battery life, and in the text mode. more than twelve hours. This is a record battery life to date.

However, it should be noted that the additional battery in the keyboard dock provides practically nothing. So, the difference in the time of watching a movie in laptop mode and in tablet mode is only 10 minutes, which, of course, is very small and is actually comparable to the measurement error.

Keyboard

The Asus Transformer Book T300LA laptop uses the island-style keyboard with an increased distance between the keys, which has already become traditional for modern laptops. A separate numeric block (NumPad), as well as keyboard backlighting, is not provided in this case.

laptop, monitor

The main keys on the keyboard are 15.4 x 15.4 mm in size. The keys themselves are plastic, black.

The keyboard in the laptop is slightly recessed in relation to the work surface. over, holes are cut in the working surface for each key.

The quality of the keyboard in this notebook can be considered very good. Of the advantages, we can note the fact that it has a rigid base and does not bend when you press the keys. When typing, the keys do not emit an unpleasant clacking sound, the key travel is moderately spring-loaded and with a light, barely noticeable depression.

The location of the keys themselves is quite standard and raises no objections.

The top row of keys traditionally has two functions: either the traditional F1-F12, or laptop control functions, one set works directly, the second in combination with the Fn function key. over, in the upper row of keys there is one special key, pressing which leads to the launch of the Asus Console utility for quick configuration of the laptop.

Hybrid notebook-tablet Asus Transformer Book T300LA

In early December 2013, Asus announced on the Russian market a new 13.3-inch hybrid laptop Transformer Book T300LA based on the fourth generation Intel Core processor, a distinctive feature of which is a detachable display that can work as an independent device. a tablet running the Windows 8 operating system. The laptop went on sale at the end of December, but we also got a preliminary engineering version for tests, and therefore such moments as packaging and packaging will remain outside the scope of our review.

Appearance and ergonomics of the case

Despite the fact that formally the Asus device does not belong to the category of ultrabooks, in terms of its characteristics and concept of use, this laptop can well be attributed to the category of third generation ultrabooks.

Indeed, the dimensions of the Asus Transformer Book T300LA are 34.2 x 21.6 x 2.34 cm, and its weight is 1.9 kg. At the same time, do not forget that this is not a classic laptop, but a convertible laptop, in which the detachable screen is a full-fledged tablet. In tablet mode, the overall dimensions are 34.2 x 21.6 x 1.15 cm, and the weight of the tablet is 1.1 kg. The docking station itself (keyboard with additional battery) measures 34.0 x 21.6 x 1.1 cm and weighs 0.8 kg.

The case of the Asus Transformer Book T300LA laptop is made almost entirely of dark silver metal. And only the bottom of the dock is made of plastic.

The system for attaching the screen to the docking station is one long hinge that is located at the top of the docking station (above the keyboard). This loop has a magnetic groove into which the screen is installed. In order to detach the screen from the docking station, you must press the button located at the top center of the hinge. In addition, after connecting the keyboard dock to connect it, you must connect it using the dedicated toggle switch located in the upper left corner of the docking station. There is an indicator next to this toggle switch that will light up when the dock is turned on. There is also a traditional Caps Lock indicator.

The system of attaching the screen to the docking station allows you to deflect the screen itself relative to the plane of the keyboard at an angle of approximately 115 degrees, which, of course, may not be enough in some conditions. However, such a small opening angle of the screen is a problem of many laptops with a detachable screen. And the point in this case is not in any peculiarities of the hinge hinge, but in the fact that with a larger opening angle of the screen, the system will become unstable. Indeed, since the mass of the docking station is only 0.8 kg, and the mass of the screen is 1.1 kg, then with a larger opening angle of the screen, such a system will simply overturn. Even with an opening angle of 115 degrees, it cannot be said that the position of the laptop on the table is very stable. It is enough to touch the screen with your hand a little, and the laptop will tip over and take a position of stable balance when the heavy screen lies on the table.

Also note that when the laptop is placed horizontally on the table in the closed state, it rests on four rubber feet and its position is very stable. However, when the screen is opened, the laptop begins to lean on the table with the protruding edge of the screen. At the same time, the lower part of the laptop rises slightly and the two rubber feet no longer touch the table. It is no longer possible to call this position of the laptop stable. The laptop slides easily on the table and there is a risk of scratching both the table itself and the edge of the laptop screen.

If we talk about the tablet mode of using the Asus Transformer Book T300LA hybrid notebook, then the following circumstance should be borne in mind. In tablet mode, this device is quite heavy. Nevertheless, the weight of 1.1 kg for a tablet is a bit too much and such a tablet cannot be held in the hands for a long time. Therefore, first of all, Asus Transformer Book T300LA is just a laptop, and the tablet mode can be considered as an additional feature.

The tablet part of the laptop, that is, the detachable screen, has one USB 3.0 interface and a Micro-HDMI connector for connecting an external monitor. Both connectors are located on the left side of the tablet. In addition, on the left side there is a mini-jack audio jack for connecting headphones, a power jack, a rocker-type key for controlling the sound volume and an LED indicator of the battery charge. This indicator is white when the dock or tablet is connected to a power source and the battery is 95-100% charged. If the battery is orange, it means that the docking station is running on AC power and the battery is less than 95% charged, or the tablet is connected to the docking station for recharging, and the battery charge is less than 30%. A blinking orange battery indicates the dock or tablet is powered on and the battery has less than 10% charge. WELL, and if the indicator is off, then this means that the docking station or tablet is running on battery power, and the charge level is in the range from 10 to 100%.

On the top of the tablet (on the left side) there is a power button.

Well, at the bottom there is a slot for SD / SDHC memory cards (this slot is not available in laptop mode).

In addition, the tablet also has a traditional Windows key, pressing which in tablet mode returns to the home screen.

Also, the tablet has two traditional cameras (front and rear) and an ambient light sensor, which allows you to automatically adjust the screen brightness and, of course, a built-in accelerometer, which is responsible for screen rotation, which is important in tablet mode. However, how to block the screen rotation function (a typical feature for tablets) remained a mystery to us. The user manual does not say anything about this, and there are no special lock buttons.

On the keyboard dock itself, on its left side there is only one microUSB connector, which is designed to charge the battery of the keyboard dock itself. In this case, it is assumed that to charge the docking station, it is necessary to connect it with a USB cable (it should be included in the package) with the tablet. Actually, this, in our opinion, is another drawback of this laptop. That is, if you want to recharge the docking station, you will have to occupy the only USB port on the tablet, which, of course, is inconvenient. And constantly carrying another cable with you is not at all comme il faut. And why it is not possible to charge the docking station directly through the tablet when it is connected is absolutely not clear. After all, such a solution is both logical and convenient.

Touchpad

The Asus Transformer Book T300LA laptop uses a classic clickpad with simulated keystrokes. The dimensions of the working area of ​​the touchpad are 106 × 62 mm, which is quite enough for comfortable work. The touchpad supports multi-touch function, and details of supported gestures can be found in the user manual.

The touch surface has a slight roughness and is barely noticeably deepened. The touchpad’s sensitivity is not satisfactory. The only caveat is a slight backlash when you press the keys, as a result of which they emit a clattering sound.

There is another drawback regarding both the touchpad and keyboard. The fact is that sometimes (and, as a rule, at the most inopportune moment) the docking station “falls off” along with the keyboard and touchpad, and in this case you either have to use the toggle switch to reconnect the docking station, or even restart the laptop. It has been noticed that especially often the keyboard and touchpad freeze when using the USB connector on the tablet (when an external USB drive is connected to the laptop or the docking station is connected to the tablet via a USB cable for charging). It is possible, of course, that this is the problem of our engineering sample of the laptop, but perhaps not. And if this problem is observed on samples that go on sale, then this, of course, will be the biggest drawback of the Asus Transformer Book T300LA laptop.

Work under load and idle

In idle mode, as it should be, the processor frequency in a laptop is 800 MHz (of course, we are talking about a balanced power consumption scheme), that is, there are no complaints about Intel SpeedStep technology. At the same time, the processor temperature in idle mode is no more than 35 ° C, which can be considered a very good result.

When the processor is loaded with the Stress CPU test (AIDA64 Extreme Edition utility. system stability test), which uses integer calculations, the processor frequency is 2.3 GHz. (Recall that for an Intel Core i5-4200U processor, the maximum frequency in Intel Turbo Boost mode is 2.6 GHz). The processor temperature in this boot mode does not exceed 60 ° C.

In principle, it should be so, since in this case all processor cores are loaded, and the maximum frequency in Intel Turbo Boost mode is reached when only one core is loaded and the requirements for power consumption and processor temperature are not exceeded.

When the processor is loaded with the Stress FPU test, which uses floating point calculations and heats up the processor to a greater extent, the maximum settled processor frequency is 1.9 GHz, and the temperature of the processor cores does not exceed 75 ° C.

Screen

As already noted, the Asus Transformer Book T300LA laptop uses a 13.3-inch IPS screen with a resolution of 1920 × 1080. The screen, of course, is touch-sensitive and, like the touchpad, supports the multi-touch function.

According to our measurements, the maximum brightness of the screen against a white background is 212 cd / m², and the brightness against a black background is 0.25 cd / m². At maximum screen brightness, the contrast is 839: 1 and the gamma value is 2.32. In general, of course, the maximum screen brightness is too small. Even visually, when working with this laptop, I want to make the brightness higher.

The minimum screen brightness is 12.4 cd / m² against a white background and 0.04 cd / m² against a black background. At minimum screen brightness, contrast is 349: 1 and gamma is 2.32.

Screen test results
Maximum white brightness 212 cd / m²
Minimum white brightness 10.4 cd / m²
Contrast (at maximum brightness) 839: 1
Gamma 2.32

Asus Transformer Book T300LA has a color gamut of 91.3% of sRGB and 66.8% of Adobe RGB, and a color gamut of 100% of sRGB and 68.9% of Adobe RGB. Basically, this is a very good result.

The color filters of the LCD matrix mix the components a little with each other. As a result, the spectra of red and green overlap partially. At the same time, the blue spectrum is well isolated. In principle, this situation is quite typical for LCD matrices used in laptops.

The color temperature of the Asus Transformer Book T300LA’s LCD screen is ideal. It is stable and is approximately 6100 K. in the entire gray scale range (temperature changes in dark areas can be ignored, since this is caused by the instrument error in dark tones).

The color temperature stability is explained by the fact that the balance of the primary colors remains unchanged over the entire gray scale range.

As for the color accuracy (delta E), its value remains fairly stable across the entire gray scale (we do not take into account the dark areas) and ranges from 9 to 11 units. In principle, this is an acceptable value for this class of devices.

If we talk about the viewing angles of the screen, then they are really very wide. over, wide not only horizontal but also vertical angles, which is especially important in tablet mode. When looking at the image from any angle, the color does not distort and visually only slightly decreases the brightness

In general, we can say that the IPS-matrix in the Asus Transformer Book T300LA laptop is very good. It has a wide color gamut, very stable color temperature and acceptable color accuracy. The only drawback is the not very high maximum screen brightness.

Sound path

The audio subsystem of the Asus Transformer Book T300LA laptop is based on the Conexant CX20751 HD codec, but the laptop itself has two built-in speakers.

Subjectively, the acoustics in this ultrabook are quite good. The volume is sufficient and the sound quality will satisfy most users.

To evaluate the audio output path intended for connecting headphones or external acoustics, we resorted to instrumental testing using an external Creative E-MU 0204 USB sound card and the RightMark Audio Analyzer 6.3.0 utility. Tested in stereo, 24-bit / 44.1 kHz.

According to the test results, the audio path in the Asus Transformer Book T300LA laptop is good. There are no unsatisfactory marks in any test, and most of the tests are performed for the grade Good.

How to use a laptop as a monitor for a computer: 3 ways to connect

If the PC screen is out of order, and there is no opportunity or time to purchase a new one, you can use the laptop as a monitor. Also, the option is suitable so as not to dispose of a non-working laptop, but still use it for some time.

The article provides detailed instructions on how to connect a laptop screen to a computer using a cable, program or video capture card. The methods are also useful if you need to demonstrate in all its “glory” information from a laptop on a large monitor.

Controlling a PC on a laptop via remote access programs

If you don’t have a cable at hand, you can use the wireless method to connect your laptop and PC. The method is relevant for owners of Apple devices. There is a special option called Air Display (not available in all versions of the devices, you may need to install the application).

The program is freely available, you can easily download it from the Internet. To install, you just need to follow the instructions, everything is intuitive.

If the program is already on your laptop, then you can connect to the PC as follows:

  • select the program icon on the taskbar and click on it;
  • in the window that opens with a list of available devices, select the desired one;
  • click on Connect and wait for the connection.

That’s it, now you can display an image, text information from a computer to a laptop. Air Display helps to use monitors together, all actions are carried out as a remote connection.

Connecting a laptop to a PC using a cable

This method requires preparation. buying a cable if it is not there. To correctly determine the required cord, it is worth finding out the connectors of the devices. You can find devices with VGA, DP ports (for example, HP 15-dw1004ur), HDMI, USB. We pay attention to this when choosing a cable.

Recommendations on how to properly connect a laptop to a computer using a cable:

  • One end of the cord must be inserted into the laptop connector, the other into the PC port.
  • Start both devices.
  • After the desktop appears on the screen, click on an empty space with the right mouse button.
  • In the menu that appears, select “Properties” or “Screen resolution” (depending on the OS), the display options will appear.
  • There will also be a list and pictures with monitors, you need to select the connected laptop monitor by name or click on the image under number 2.
  • In the field “Multiple screens” select “Show desktop on”.
  • To save all changes, you need to click on “OK”.

Connection using a video capture card

Another way is to purchase a USB video capture card. This will provide an opportunity to seamlessly use both a monitor and a keyboard in a laptop. The board is connected with one side to the PC, the other to the laptop.

You can work with the board from any device equipped with USB connectors. All drivers are included, so there will be no problems installing it. At the same time, the best option is to use a standard wired connection between a PC and a laptop, since this will require fewer resources.

The advice in this manual is very real and useful even for non-computer technicians. The first and third methods involve small additional expenses. the purchase of a cable and a video capture card. The second method is optimal for owners of “apple” devices, there is no need to spend money, just install the application. The choice of the method of connecting a laptop to a PC is up to the user, who only has to study all 3 and choose the most convenient, fast and simple of them.

Save battery power

If you turn on loud music on your laptop and move away from it, then the display does not need to drain the battery power. Using a combination of the Fn key and the corresponding screen button on a laptop, you can dim the monitor, thereby increasing the duration of the battery-free operation. Typically, the display key is in the top row of F1-F12 auxiliary buttons.

By the way, using a combination of buttons, you can increase and decrease the volume, brightness and even flip the laptop screen, that is, the image on it. The latter is used more often on personal computers than on portable devices.

You can also configure the display to turn off on the laptop in the power options. After a certain time interval you have set, the operating system can independently turn off the monitor on the laptop, and send it to sleep mode, if necessary.

How to deactivate the display

There are several ways to turn off your laptop monitor:

  • Using the keyboard shortcut.
  • By adjusting the power settings to deactivate the display after a specified period of time.
  • By physically disconnecting the display from the laptop.
  • Closing or closing the lid of the laptop.
  • By setting the display mode in the display options.

The first two methods will work for you if you want to conserve battery power on your laptop. The other three methods are effective when connecting an external display to the device. Let’s take a closer look at how to turn off the monitor on a laptop using a keyboard shortcut and other methods.

How to turn off the monitor on a laptop, and why you need it?

Some laptop users prefer to work behind large screens by connecting an external monitor to the device. In some cases, such a screen may be needed if the matrix is ​​out of order (so as not to spend money on its replacement).

It is also important to know that the display of a mobile computer is a significant drain on the battery. If you’re just using your device to listen to music, you can turn off the display to extend battery life. Let’s figure out how to turn off the monitor on a laptop.

Turn off the screen of the mobile PC when using an additional device

If you are going to use an external monitor of a larger size and resolution, and the laptop display only distracts you, then you can:

  • In the screen options, set the display to only the external display.
  • Cover the laptop cover or close it completely, and then the screen will turn off. True, in this case, the keyboard and touchpad of the laptop will not be available to you and you will have to connect additional manipulators.

If you have damaged or broken the matrix of a laptop and now use only an external display, then experts advise to disconnect the matrix cable from the motherboard. If you do not know how to disconnect a laptop monitor physically, how to disassemble it, then we do not advise you to try to do it yourself. Contact a specialized service center. A faulty matrix can lead to failure of the entire laptop motherboard on power supply.

How to connect multiple monitors to a laptop

It’s very easy to connect a monitor to a laptop, but what if you need to connect multiple screens to a laptop at once? We have prepared a simple instruction and selected a couple of useful programs for setting up monitors.

READ  Choose a Laptop For Study At The Institute

The more monitors, the better, especially if the laptop has a very small screen. Our tips will help you connect multiple monitors to your laptop and set them up.

We connect the monitor via HDMI, Displayport or VGA

If you have the most common computer monitor, simply connect it to your laptop via HDMI, DisplayPort, or VGA. On most laptops, the [Fn] [F] key combination is used to set up multiple monitors. In this menu, you can choose whether only one screen will be used or all at once.

The easiest way to find out if your laptop supports multiple external monitors is on the manufacturer’s website. Most devices are not capable of this, even if they have two connectors. There are monitors such as the ASUS MB168B that can be connected to a laptop via USB. In this case, power is also provided via the USB connection.

Our advice. Connect two monitors to a laptop at the same time: one through the VGA or HDMI port, and the other through USB. this combination works great with most laptops.

How to use your tablet as a monitor

As a second monitor, you can use an Android tablet or iPad. But to connect it, you need a special application.

  • Download and install the iDisplay software on your laptop. Then install the app of the same name on your iPad or Android tablet. Download iDisplay here.
  • If you are using an iPad, then both it and the laptop must be connected to the same Wi-Fi network. To connect, enter the IP address of your computer in the application.
  • An Android tablet can also be connected via Wi-Fi. If there is no free network nearby, connect the devices using USB.
  • After connecting all devices via the iDisplay app, the tablet can be used as a monitor.

Programs for connecting multiple monitors

If you are having trouble using a second monitor, take a look at these programs:

  • Dual Monitor Taskbar. If you have connected a second monitor, the taskbar will only appear on one of them. Dual Monitor Taskbar will solve the problem and expand the taskbar to all monitors.
  • MurGeeMon. This app will help you manage all monitors. For example, in a couple of clicks, change the resolution of one of them.
  • DisplayFusion. Use the program to choose a suitable background for your screens. The tool stretches images across both monitors, so you need a high resolution wallpaper.

And in this article we tell you what to do if you find a dead pixel on your monitor.

Ways to connect a laptop as a monitor

The most stable and reliable way to do this is by cable connection. Depending on the laptop model, its external interfaces may differ. You can use a laptop as a monitor through the HDMI connector or through the VGA output. If the system unit contains only an HDMI jack, and the laptop is equipped with a VGA input, then a special adapter is required for their joint work.

How to connect a laptop as a monitor

Use a laptop as a monitor using a cable connection

Having decided on the necessary cable and using it to establish a connection between the system unit and the laptop, we proceed to setting up the display. To do this, turn on the laptop and wait for it to fully load. After that, we activate the settings menu item “Properties” or “Screen resolution” (depending on the installed operating system) by right-clicking on an empty space on the desktop. In the window that opens, we see the parameters of the current display.

To use a laptop as a computer display, you need to select the required monitor by name from the list that appears. Then you need to extend the PC desktop to the connected device by checking the box next to the corresponding menu item. To do this, you need to confirm the changes made by clicking the “Apply” button, and then “OK”. After completing these simple settings, you will be using the laptop screen as your main monitor.

  • reliable connection;
  • stable data transfer rate;
  • simple settings.
  • lack of the required cable;
  • mismatch between laptop and stationary PC connectors;
  • the need to purchase an adapter.

How to use a laptop as a computer monitor or another laptop

There may be several situations when there is a need to use a laptop as a monitor. The most common problem is the failure of the main display of a personal computer. Therefore, in order to use the power of the system unit and the data stored in it in the future, you will need a monitor of another external device. The same situation can occur if the display matrix of another laptop does not work correctly.

How to use a laptop as a display over Wi-Fi

For computers with the operating system Windows 7 and later, as well as Mac devices, there is a special program Air Display. It allows you to quickly and efficiently connect your laptop as a computer monitor wirelessly. To do this, the application must be installed and activated simultaneously on two devices. By following simple setup points, following clear prompts, you will quickly achieve the desired result.

A stable connection of the laptop as the main display of the PC will be provided by the MaxiVista utility. It is specially designed for this function and is available in two versions:

  • client (for a managed device whose monitor will be used as the main one);
  • server room (needs to be installed on the main device).

When launching the application, the server should automatically detect the client laptop. After connecting to it and completing the step-by-step settings, you can use the laptop as a computer monitor. The main disadvantage of this utility is that it is not free and is not cheap. In addition, there are a number of programs that allow you to remotely use the display of a paired device:

  • TeamViewer;
  • Radmin;
  • RDesktop and others.

These applications have their own characteristics and more complex configuration. Among all the listed methods, each user will be able to choose and apply in his case the most convenient and accessible option for him.

At what height to hang the TV stand. What form do TV cabinets produce?

A floor-standing TV stand in the form of a rack is a common piece of furniture. Includes a bracket for mounting a flat display TV. Thanks to this mechanism, you can change the angle of rotation and tilt of the screen, which allows you to watch it from any part of the room. Also, such a device will securely fix the TV and protect it from falling.

Classic TV stand is used only as a stand.

A TV cabinet is a practical option for furniture, which perfectly combines a stand for appliances and a chest of drawers with drawers and shelves. On the latter, you can place various equipment, for example, speakers or a DVD player. Various things can be stored in the drawers of the chest of drawers.

Hanging TV stand with wall mount. It can have various additional sections, allows you to save significant space in the room, but is not designed for heavy loads.

Corner TV stand. Its practical and comfortable shape is suitable for small spaces. The difference between this model and others lies in its configuration, and the functions can be the same.

Location

Before deciding at what height to hang the TV in the bedroom, you first need to decide on the place where it will be located. The choice of the right place will depend on both the viewing comfort and the height at which the device itself will hang.

To determine the location, you need to lie on a sofa or bed in the bedroom in a comfortable and familiar position for you. Now you need to determine on which wall the TV should be mounted so that it is as convenient and comfortable to watch it as possible.

Experienced experts say that the optimal location is a point drawn in a straight line from the center of the bed to the wall, and the height of this point will be adjusted later. It is with this arrangement that the TV will be clearly visible to all people who are located in the bedroom, and when viewing it there will be no inconvenience.

If the device is to be hung in a single room or nursery, it must be positioned diagonally from the center of the bed. In this case, even when turning, there will be no discomfort when viewing, and the screen will be clearly visible from any position.

When the potential location of the TV has already been selected, you can directly start calculating the height at which it will need to be fixed.

Height

You can choose the optimal height for placing the TV on the wall in one of two ways. The first is based on the usual viewing comfort, and the second is based on medical advice and advice from the manufacturer.

  • You can determine the height level where the bracket mounts will be located if you lie in your favorite position on the bed, close your eyes for a second, and then open them sharply and immediately look at the wall. The point at which your gaze rests will be the middle of the television screen. This means that this is where the main bracket will be located. Choosing this option, it should be understood that parameters such as the distance from the bed to the wall and the dimensions of the diagonal of the screen are not taken into account here. So, choosing this method, you cannot be sure of the safety and comfort of your eyes when watching TV, hung in this way.
  • The second method is based on mathematical calculations and advice from doctors. The optimal distance between the eyes and a device with a liquid crystal screen is considered to be its diagonal multiplied by three, and for plasma screens this is the product of the diagonal and the number 4.

How high should a 55-inch TV be hung in the bedroom. At what height to hang the TV in the bedroom: room features

The location of the TV directly depends on the parameters of the bed, namely, on its height. To decide at what height to hang the TV in the bedroom, you need to take a comfortable position on the bed, close your eyes and relax for a while. When you open your eyes, you should intuitively mark a point on the wall, which should become the center of the device screen. The best option is to install the TV in the bedroom on the wall at a height of 1-1.5 m.

Helpful advice! The TV must be installed above the fixation point of the direct gaze in a standing position for a supine position.

In this case, the TV will be installed higher than in the living room. Note, however, that the screen should not be tilted off-center when watching TV. The optimum value is 30 °. Otherwise, there will be problems with the cervical spine, which will lead to osteochondrosis.

Choosing the best place, height and location. Which bracket do you prefer? Advantages of wall mounting. Installation features.

The plane of the screen should be perpendicular to the line of sight. If a person watches TV in a supine position, with his head thrown back on the pillow, the monitor must be raised to the height of his gaze, while tilting the upper edge of the device away from the wall. In this case, the screen can be placed on the ceiling.

The height of the device in the bedroom depends on the position in which you plan to watch TV

In the bedroom, the TV can be fixed to the ceiling. However, it does not have to be installed near the wall opposite the head of the bed. The device can be located directly above the bed. In this case, it is important to choose a reliable type of bracket.

READ  Is there Bluetooth on a Lenovo laptop

The TV in the bedroom should be hung on an inclined bracket, which will allow you to adjust the angle of the screen in the vertical plane. You can choose a tilt-retractable or tilt-swivel product type. Its middle is fixed at a distance of at least 160 cm from the floor. Often the question arises, at what height to make a socket for a TV. On the wall, the outlets should be located above the bracket at a distance of 25 cm.

Please be aware that LCD TVs are too sensitive to vertical tilt. If the monitor is positioned too low, the picture will be dark, and high placement suggests a very light picture.

At what height should the TV be hung 50 inches. At what height to hang the TV in the living room: useful recommendations

To determine at what height from the floor to hang the TV in the hall, you should sit comfortably and look directly at the wall. The head should not be thrown back, so as not to create a load on the cervical spine. The direction of the eyes will point to the point that should be the middle of the screen.

Important! Opposite the eyes of a person, the center of the TV screen or its upper third must be located.

The optimal distance to the TV from the floor for the living room is 1.4-1.6 m. The height of upholstered furniture and the average height of family members are also taken into account. With a standard sofa height, the optimal screen level for children and adults will be different, so the average TV height is determined.

The TV in the living room is hung at a height corresponding to the level of the eyes of a sitting person

If you plan to watch TV from the couch, you can position it just below the recommended level. If the hall is combined with the dining room, and the viewing of broadcasts is often carried out in a sitting position at the table, the unit can be hung slightly higher.

Helpful advice! The larger the diagonal of the TV, the lower it should be placed in relation to the floor.

Many people install the TV in special furniture niches. However, this decision is not always correct. This also takes into account the size of the screen and the height of the sofa from the floor. Imbalance may occur, causing inconvenience while watching.

To mount the TV in the living room, it is better to give preference to a universal bracket, thanks to which you can adjust the position of the screen both vertically and horizontally.

At what distance to hang the TV on the wall in the bedroom. At what height should the TV be hung in the bedroom?

After repairs in the bedroom, many people also update the equipment in this room. After purchasing a TV, many do not know at what height to hang it. Indeed, not only viewing convenience, but also safety will depend on its correct location.

Monitor matrix overclocking. theory and practice

I think that most PC users have heard about the fact that you can overclock a processor, video card or RAM. However, few people know about the fact that you can also overclock the monitor, and often the difference from its overclocking is more significant and noticeable than from overclocking other hardware. It is also safer, but more on that below.

Theory To begin with, what is meant by overclocking a monitor matrix? This implies an increase in the refresh rate of the monitor from the standard 60 Hz and by how much it will turn out. 70-75, sometimes 120, and even 150 Hz (!). Why is this needed? To improve the smoothness of the picture. What does it mean that the refresh rate of the monitor is 60 Hz? This means that the picture on the screen changes exactly 60 times per second. In this case, the video card can produce both a lower number of fps and more. If the number of frames issued by the video card is less than the refresh rate, then some frame will be displayed twice (or even three times), which can lead to noticeable delays. If the number of frames issued by the video card is greater than the monitor’s refresh rate, then it will turn out that two or three frames will be displayed on the screen at once, which will lead to artifacts:

The trade-off is the vertical sync setting. What is its essence? It tightly links one frame, prepared by the video card, to one update of the image on the monitor. And here, if your video card consistently produces more frames than the refresh rate of the monitor, then you will get an ideal smooth picture, but your video card will not be 100% loaded at times and will rest. And it is precisely this mode of operation that is often used in the system. for example, when you scroll in the browser, you do not see artifacts, and at the same time the scrolling is smooth.

Raising the refresh rate of the monitor kills two birds with one stone: firstly, now the vertical sync will go at a higher frequency, which means the smoothness will increase even more (I think everyone saw the difference in YouTube videos with 30 and 60 frames? Here also). Secondly, if your video card in games produced more than 60 frames per second, then now the threshold for the appearance of artifacts is pushed back to the new refresh rate, while the information on the screen will be updated more often, which is quite important for dynamic games.

Of course, the question arises. how safe is it? It is much safer than overclocking hardware: if the monitor cannot work at a given frequency, it simply will not turn on. If it works at a given frequency, it means that you will not have any problems. Overheating, as in the case of overclocking a processor or video card, is definitely not in danger.

Practice Now that we have figured out a little theory, you can move on to practice. The first thing you need to know is that any monitor and even laptop matrices are chasing, but there are several limiting factors at once. The first is the connection method: via DVI at a resolution of 1920×1080, you are unlikely to get more than 65 Hz. the reason is the rather low bandwidth of the interface. Through older HDMIs (up to 1.4) at the same resolution, you will most likely be able to get around 75-85 Hz. Well, through the new HDMI (1.4-2.0), Thunderbolt or DisplayPort there are practically no restrictions. you can get 120-165 Hz. Similarly, there is often no limitation for laptop matrices connected directly to the board. The second limiting factor is the matrix itself, or rather its controller. It happens that even with a fast connection, when the frequency increases, some image artifacts appear. alas, there is nothing you can do about it, except how to reduce the frequency to the last stable one.

Now let’s talk about how to overclock. Owners of video cards from Nvidia are lucky here. for them the algorithm is simple: you need to go to the Nvidia control panel, go to the “Change resolution” tab, click on the “Settings” button, in the window that opens, check the box to enable modes that are not supported by the display, and then click on the “Create custom resolution” button, and in the window that opens, we finally get access to change the refresh rate:

The frequency should be raised by 3-5 Hz, then press the “Test” button. If no artifacts appear and there is an image, raise the frequency even higher. As soon as artifacts appear or the image disappears, reduce it to the previous operating frequency, and then raise it by 1 Hz. in general, everything here is exactly the same as with normal overclocking of a video card. After you have found the desired refresh rate, simply save the resulting configuration, and it will appear in user permissions.

As you can see, there is no risk here. if the monitor “does not start up” at the frequency you specified, after 20 seconds the system will roll back the frequency value to the default. Alas, everything is so good only with video cards from Nvidia, with video cards from AMD or Intel everything is worse. there you cannot increase the frequency in the driver settings, however, there is a universal application that will help you do this. it is called Custom Resolution Utility (CRU), download its latest version can be found here.

I will warn you right away. the program’s problem is that it does not have a Test button, as is the case with Nvidia, so the frequencies are applied immediately and irrevocably. So if after setting the frequency you see a black screen, either connecting a second monitor and returning the settings to default will help you, or entering through safe mode and doing the same.

Working with the program is quite simple. you launch it, remove all resolutions from the standard ones and uncheck all the boxes on the left (I will not do this for myself, because I have already overclocked the matrix through the Nvidia settings): Now, under the window with Detailed resolutions, click on the Add button, set Automatic. LCD Reduced and below we change the refresh rate: Here the principle is the same. we increase the frequency by 3-5 Hz, click OK, save everything and reboot. Now we go into the AMD (or Intel) panel and set a new frequency: Here, in general, that’s all. as you can see, there is nothing difficult or dangerous.

Well, the last question remains. since almost all matrices are overclocked, why do not manufacturers do this from the factory? Everything is simple here: there is such a concept as a standard, and for the refresh rate of monitors it has been 60 Hz for a long time. Therefore, manufacturers, even if the matrix is ​​capable of operating at 70-80 Hz, still limit its frequency to the standard 60 Hz. Secondly. often everything depends on the connection method. For example, you can transfer 1080p60 via any interface, even DVI, even Thunderbolt 3. But for 1080p80 you already need a special cable. DVI and old HDMI are no longer suitable. And in order not to create confusion, the manufacturers again limited themselves to 60 hertz.

As for the question, to overclock or not to overclock. it’s up to you and only you. If you managed to increase the frequency from 60 to 65 Hz, then there is no point in such overclocking, you will not see the difference. But when overclocked to 75 and above Hz, the difference becomes clearly visible, so the game is worth the candle here. It should also be borne in mind that after overclocking, the load on the video card will increase during normal operation. after all, it will now have to produce more frames per second, so if you overclock the matrix on a laptop, you should take into account that your battery life will decrease slightly.
