What is important to know about HDMI?

Recently, HDMI data transmission technology has become very popular. Largely due to the fact that with its help it is possible to broadcast a video and audio signal of a sufficiently high quality. This uses only one cable.

There are currently several HDMI standards:

  • 1.0 standard (speed up to 10.2 Gbps, support up to 8 audio channels)
  • Standard 2.0 (data transfer rate up to 18 Gbps, as well as support for up to 32 audio channels).

Many companies manufacture HDMI cables. Branded options are often quite expensive. However, many modern TVs have such a cable included.

How to connect a computer or laptop to a TV via HDMI?

Many people who have a large plasma or liquid crystal TV at some point think about connecting it to their computer or laptop. The opportunity to watch a movie on a big screen is of great interest to many users. First, let’s get acquainted with the possible ways to connect THESE devices, then we’ll figure out the settings of the video card, and at the end we’ll look at how you can output sound via HDMI. For the simplest connection of the aforementioned devices, you only need to have an HDMI cable with the same connectors at the ends. Any, even the most inexpensive cable is suitable, however Note, if you are going to use 3D mode, the version of the cable must be HDMI 1.4 or higher. Find the HDMI jack on the case computer as well as on the back of your TV. This is what this socket looks like on the back of the TV: And this is an image of the socket on the side wall: But such a socket should be looked for on the back of the computer system unit: such a socket is located directly on the video card, next to the connector for connecting a DVI or VGA monitor. If a discrete video card is not installed in your system unit, the socket will be located on the motherboard, near the USB ports. With laptops, it is lighter, the HDMI socket in them always looks the same, just in different models it can be located on different sides: In portable computer devices (tablets, netbooks, cameras, etc.) install mini-HDMI connectors, which are three times smaller than a conventional connector, so they need a mini-HDMI cable.

In many modern users, the LCD TV hangs on the wall, which makes it difficult to connect a massive cable to its back surface.

For such cases, cables are provided with the plug at right angles. You can also, if you wish, purchase a special HDMI corner. With this corner you can connect to the TV from the back or from the side. Some adapters even support the ability to adjust the angle and the bend in them is not straight, but in any direction. Before buying, decide in which direction the cable will come out after connecting it through the corner. Please note that different cable models are oriented in different directions.

You will not be able to connect without HDMI connectors (however, if you have a DVI monitor connector, you can use a DVI-HDMI adapter).

How to connect laptop to TV via HDMI

Sometimes you need to connect your laptop to your TV. For example, to display an image on a larger screen. Since the “native monitor” is not always enough for comfortable viewing of photos or movies. For this, in most cases, an HDMI cable is used. After all, there is a connector for it in almost any modern TV device. You just need to understand how to connect a laptop to a TV via HDMI.

How to properly connect a laptop to a TV via HDMI?

Immediately, we note that in order to connect everything, it will be necessary to set the desired parameters on the TV and laptop. You will also need the HDMI cable itself. Also, note that some laptop models only have a DVI connector. Then you will have to acquire also a special adapter.

The procedure itself for connecting a laptop to a TV via HDMI is quite simple. You need to do the following:

  • We make sure that there are connectors on both devices.
  • We turn off the TV and laptop. This is necessary in order to protect the ports. If you connect the cable with the devices turned on, then there is a risk of their failure.
  • Connect one end of the cable to the HDMI connector on the TV. Usually in modern TV-devices, it is located at the back or side. In this case, there can be several connectors. Usually they are all signed. HDMI 1, HDMI 2, etc. In which one do you Connect the difference cord comments.
  • Connect the other end of the cable to your laptop. Now turn on both devices and go to the connection settings.
  • We start with the TV. We take in hand the remote control and press the button on it, which is responsible for setting up signal sources. Often this is the “input”, “source” key (on LG, Samsung TVs, etc.) or “home” (on some Sony models).
  • A menu will appear on the TV screen (its interface is very different depending on the TV and the manufacturer!), Where you need to select the signal source. In our case, HDMI. If you choose the wrong option, the following message will appear on the TV screen: “Signal Sun”. Don’t be scared! Just click on another signal source.
  • That’s all. Most likely, everything worked out for you, and you are already watching a movie or playing computer games using a TV monitor, and not a laptop screen.
  • If the laptop is NOT connected to the TV and it was not possible to display the image on its screen, then on the laptop we go to “Start”. Further in the “Control Panel”. Click on the item “Setting the screen resolution”. Next, in the “Screen” line, select the TV screen if it was NOT automatically recognized. Press the button “Find”. For laptops with Windows 10, you need to go to the system settings in the “Screen” section and call the “detect” button.

Helpful information! Not all laptop models have an HDMI connector. In this case, some users, using an adapter, connect the device via VGA. This is a rather old 15-pin connector that became popular back in the 80s of the last century. However, due to this interface, no sound is transmitted. Therefore, in addition to the HDMI cable, you will need to connect an additional wire for the audio signal.

Problems when connecting a laptop to a TV via an HDMI cable are far from uncommon. Therefore, we will dwell on this point in detail. we will describe the most common problems and ways to solve them.

  • What if you connected everything correctly, but the TV screen does not show the image from the laptop? The first thing we do is sit down at the laptop. Right-click on the desktop. In the menu that appears, select the term “Screen resolution” (for windows 7, 8). Now you need to select “Multiple monitors” in the “Screen” item. Below you will see another option “Multiple screens”. Here we put “Duplicate desktop on the first and second”.
  • Why is there no sound on the TV? As we noted above, an HDMI cable carries an audio signal. So weird if the sound continues to come from the laptop and not from the TV device? How to fix it? Go to the notification panel and click on the sound icon. We choose “Playback devices” or “Sound devices”. it all depends on the OS version (Windows 7, 8, 10, etc.). In the list that opens, there should also be a TV to which you “legalized” the laptop via HDMI. Click on it with the right mouse button, and then select “Use as default” or “Enable”. It remains only to click “Ok”. The sound should appear.

If, anyway, the TV does not see the laptop via HDMI, then it is worth checking if you have connected the cable itself well to all the connectors. The plug may NOT be fully seated in the jack. Sometimes it happens that the cable is NOT serviceable either. But this is very rare.

Sometimes there are conflicts that prevent the laptop from connecting to a TV via HDMI. The main reason is outdated or malfunctioning drivers. For example, video cards. Therefore, if you cannot connect the device to the TV, then update the software for the video adapter.

On a note! Connecting a laptop to an old TV via HDMI is unlikely to work. Mainly due to the lack of an appropriate interface. Therefore, if you have a rather “ancient” TV receiver, then you can connect it to a laptop only through RCA (everyone knows them as “tulips”).

Features of setting up multiple displays. Extending the desktop

For a computer and a TV connected to it via HDMI, you can adjust the frequency and resolution of the screen separately. In the settings of video cards AMD (ATI), NVidia, etc. There are some possibilities associated with the installation of multiple displays. For example, when using an NVidia GeForce video card, right-click on an empty space on the desktop, and then select the line “NVidia Control Panel”. You can customize your monitors in the “Display” section:

switch, hdmi, laptop

Switching laptop video cards with special programs

Such programs will be useful for more convenient and safe switching of discrete rates. Below are options for models from AMD and NVidia.

For AMD-controlled devices, there are also AMD VISION utilities. In it, you can switch the video card like this:

  • Select “Performance”;
  • Then. Dual Graphics;
  • Named “Disable”, save changes.

How to change the video card on a laptop through the device manager

When there are two adapters in the display settings, for example, Radeon as discrete and Intel as integrated, you only need to right-click on one of them and select “Disable”.

After that, the laptop display will turn off, and the user will need to reboot the system. Despite the simplicity of the method, it is not worth using if you have no experience. High probability to disable or enable “something cannot” and thus disrupt the system operation.

What is the video adapter responsible for on a laptop?

The GPU is responsible for the graphics performance of a laptop or computer. It is not only about the display of the image on the screen and its quality. Here is the amount of video memory, support for various technologies and codecs depends on the compatibility of the system with GPU-intensive programs and games.

Video adapters are divided into two main types:

Built-in. the video chip is integrated directly into the processor or soldered into the motherboard. Devices of this type do NOT have high performance indicators. For office tasks or watching movies online, this option is suitable, but for modern games, working with graphics it is not enough.

A discrete video adapter is a separate device, which, in addition to the functions of an integrated chip, significantly expands the functionality of a PC. With the launch and work in professional graphics software, the passage of modern games, problems in this case do not arise.

How to switch between video cards on a laptop

Most often, the system itself switches between 2 cards depending on the load and requirements for a specific task. But this is not always the case. Then below we will talk in 3 ways that will help you do it yourself.

How to switch the graphics card on a laptop: 3 simple and effective ways

Laptops can have 2 video cards: integrated (for everyday tasks) and discrete. for video editing and modern games. Integrated GPUs are weaker than discrete GPUs, but they consume less power. Therefore, if you do not need to run heavy utilities, then you do not have to think about switching. However, if you need to work with games or advanced graphic editors, then knowing how to switch video cards on a laptop will come in handy. And this article is just about that.

Working with two adapters at the same time

It happens that even a discrete video adapter is not enough to play at higher graphics settings or work with a heavy graphics utility. In this case, combining the power of the integrated and discrete GPU can help out.

To use integrated and discrete video cards at the same time, you must:

  • Go to BIOS (advanced mode);
  • Go to the “Advanced” tab;
  • Named for “System Agent Configuration”;
  • In the Graphics Settings, enable the IGPU function. Here you can also specify the main monitor and memory that is allocated to the integrated video chip.
  • Save changes.

How to switch the video card in BIOS

Changing one active video chip to another, as a rule, is performed in the BIOS section, which is called “Peripherals”, or in the “Config”, “Advanced” branches. It all depends on the device model and BIOS version.

Important: the settings for changing the Video Chip may be different. Sometimes it is enough to just click “Disabled”, but in some cases you will need to drag the card you want to use now to the first position in the list.

The method is suitable for both PCs and laptops. Almost all BIOSes have this option, but there are exceptions. To find out if the system supports the function, you need to call F2 during OS boot.

What to do if you can’t switch between video cards

If we are talking about a bundle of “related” components. the manufacturer of the integrated and separate GPU is the same. in most cases the problem is solved by installing Catalyst software and fresh drivers for both video cards. As mentioned above, with Catalyst, you can switch between cards yourself. Also, the utility can perform switching automatically depending on the load.

A combination of discrete and integrated GPUs from different companies also requires the installation of the above software. But in order for the cards to switch automatically, you also need to install special drivers.

Laptop owners can switch between the video cards installed in the device using several methods: classic tools built into the OS, and using SEPARATE programs developed specifically for GPUs from different manufacturers. You can choose anything. The main thing to remember: for those who are not sure of knowledge of the filling of laptops, it is better to do without amateur performance and ask the question of switching to a service center.

Why HDMI port is afraid of burnout?

Connect a computer or laptop with power on to the HDMI connector of a monitor or TV, there is a risk of burning the ports. The fact is that there is a power supply voltage on the PC case. If a cable TV antenna is connected to the TV, then the “Ground” on the TV side has zero potential. Connecting the included laptop to the TV, due to the potential difference, a current will run through the HDMI cable, which the port will NOT cope with. The connector does not have additional protection by means of power supply circuits, and its contacts go directly to the chip. The chip does NOT withstand loads and simply burns.

Connecting a powered laptop and a TV in general is not as dangerous as a PC and TV, but hot plugging of THESE two devices does NOT guarantee 100% protection. Also, hot plugging in general can be done between devices that are powered by their own battery (for example, a video camera).

The main role of HDMI inputs

The emergence of new digital interfaces such as HDMI contributed to the obsolescence of the previously used popular VGA. They not only transmitted the image at a lower quality, but also distorted it, which often caused difficulties in work. The connection in question has a large bandwidth and supports audio transmission.

In addition to HDMI, several other types of digital data transmission interfaces are popular. DVI and DisplayPort. They all have different connectors and some characteristics, which allows you to use the required connection for different situations. Read more about comparing THESE interfaces in our articles on the links below.

Cable versions

Unlike many devices, the HDMI interface has a reverse connection between any of its versions. For example, you can use a first generation cable and use the data transfer from a second generation connector. However, in this case, the baud rate and picture / sound quality will be consistent with the cable standard, not the connector.

Also, many experts recommend paying attention to the cable length / thickness ratio. The fact is that the market is full of fakes, and if there is no way to learn more about the characteristics of the cable, then you should pay attention to its appearance.

First, if the cord is long, then as it grows, the thickness should also grow. That is, a cable with a length of one and a half meters will be much thinner than a cable with a length of ten meters.

Second, safety comes first. Cable manufacturers, in order to secure their products, put special filters that prevent the occurrence of electromagnetic interference. Outwardly, they look like a cylindrical bulge at the base of the cable.

Causes of HDMI malfunction

Sometimes there are problems in the operation of devices, this may also be due to the connection interface. When using HDMI, two problems are often observed. no picture and no sound. Incorrect device settings, outdated drivers or physical breakdowns are considered to be the main causes of malfunctions. In such cases, it is recommended that you resort to one of several methods for solving auto products problems. about them.

Above, we examined in detail the main function of the HDMI interface, familiarized ourselves with the types of cables, figured out how to enable this connector on a laptop and talked about possible malfunctions. We hope our article was useful and you learned everything you need to know about connecting devices via the HDMI connector.

Port activation

In most modern devices, where the presence of an HDMI connector is implied, this interface is activated automatically, but in some cases a little adjustment is required. How to enable HDMI on a laptop?

This often happens when a laptop is used as a second monitor for a desktop computer.

To do this, you need an HDMI cable and connect it to a video card, and from it you need to connect to a laptop. If one of the devices does not have such an interface, then there is the possibility of using adapters, but then it is worth getting ready for a loss of quality.

Next, you can move on to how to enable HDMI input on a laptop. After the cable has been connected, you can turn on the laptop and wait for the system to boot completely. After that, you need to use the fnF4 key combination. However, on laptops of different models, these may be different keys. This combination activates switching monitors, so you need to look for a key with a screen image.

In the event that this method did not work, then you can use the second options. To do this, click the “Start” button and go to the “Control Panel”. Next, you need to select the item “Screen”, and in the column on the left select the option “Configure display settings”. This is HDMI setup on laptop.

To find the first display, press the button “To find”, then set the parameters of the pop-up menu “Expand these screens”. Here’s how to enable HDMI on a laptop.

Connecting to a TV without HDMI

It also happens that the laptop has the right port, so you have to resort to methods such as an HDMI to laptop adapter. To do this, you need an HDMI cable and a DVI-HDMI adapter.

All operations are carried out exclusively on de-energized equipment. Now you can start connecting. The adapter is inserted into the DVI port on the laptop, and the cable is inserted into the HDMI connector, which is located at the output.

After that, you can turn on the TV and laptop. On the laptop, press the right mouse button and select the item “Screen resolution”. A window with parameters and two screens opens. You need to select the orientation. landscape, several screens. expand these screens, then the button “Define”. This button will help you understand which screen the TV belongs to, and which laptop.

After that, you need to select the number to which the TV belongs. most often it is “2”. Then they turn on the TV and select the HDMI connection. Now you can broadcast the image and sound from your laptop to your TV.

Enabling HDMI

It is automatically enabled on all devices that support HDMI connection. Users only need to make a few simple settings so that the connection of the two devices is successful, and a clear picture and sound appears on the screen.

Usually, it is enough to change just a few parameters of the operating system and you can immediately start working on the hardware. For detailed instructions on connecting computers and laptops to a monitor via HDMI, see our articles on the links below.

Varieties of HDMI cables

As mentioned earlier, the connection of two devices is made using special cables. They come in a variety of sizes, standards, and only support certain hardware. They also have different connector types and specifications. You can read more about this in our other materials.

Role of the HDMI connector

Before you know how to enable HDMI on a laptop, you need to understand what this connector is for. With it, you can broadcast movies, clips and music. The principle of operation is simple. replacing the analog connection method, HDMI facilitates the transfer of high quality video and audio from one device to another. This can be a connection from a computer to a TV, from a smartphone to a monitor, and so on. Even video cards are connected to the monitor in this way.

Modern versions of the cable are capable of transmitting images in 2K and 4K quality. Unlike its predecessor VGA, this interface does NOT distort the image and has a higher data transfer rate when the screen is updated at 60 and 120 Hz. And the presence of an audio channel helps to avoid additional audio connections.

PlayStation 4 connection

In order to connect a game console to a computer or laptop monitor, it is enough to purchase two inexpensive adapters: for video and audio. Next, you need to do the following:

  • Insert HDMI into USB adapter and plug into the corresponding video output on the laptop.
  • Reset game console settings. To do this, you need to press the on / off button on the console and wait until It emits the Corresponding sound, indicating its shutdown.
  • Connect white and red wire “tulip” to the audio jack on the speakers. For this, an av-jack adapter is used.

This is the most common way to connect PlayStation 4 via HDMI to a laptop or desktop computer. You will also need to switch the audio and video mode on the set-top box itself. To do this, go to the console settings and select the symbol that shows the wires “tulip”. If you cannot connect the PlayStation 4 to a laptop via HDMI in this way, then the easiest way is to use a TV for a game console.

How to connect PlayStation 4 to laptop via HDMI? PC and TV connection options

Game consoles have become part of the life of gamers. Like many years ago, console fans fall into two camps. The former play for the Xbox, while the others believe that nothing can be better than the PlayStation. Still fans “curling iron” yet the overwhelming majority.

However, despite such popularity, this console often throws its owners into a stupor. Most often, gamers are wondering how to connect the PlayStation 4 to a laptop via HDMI. This is not surprising, because today most computers, laptops and TVs are equipped with a similar connector. However, not everything is as simple as it seems. First, pay attention to a few points.

Can PlayStation 4 be connected to laptop via HDMI?

The game console actually provides this connector, as well as the PC itself. There is only one important nuance. There are HDMI IN and HDMI OUT. Standard consoles and laptops have connectors that work “to the exit”. Accordingly, it is impossible to connect in this case.

However, this does not mean that the question of how to connect the PlayStation 4 to a laptop via HDMI is closed. Laptop computers designed for games and equipped with a powerful processor and a gaming video card are often equipped with the required connector, so in this case the connection is very simple: you just need to connect the set-top box and select the appropriate mode on it.

Nevertheless, the cost of such PCs is very high, so it is worth considering how to connect the PlayStation 4 to a laptop via HDMI with the introduction of an additional adapter.

Connect your console to your TV

Even a child can cope with this task. To connect a game console, just connect HDMI to the TV itself and the game console. After that, you need to turn on the console and go to the TV settings, where it is enough to select the AV mode. The game console will automatically connect to the TV and start broadcasting the image. You can also connect the console to the World Wide Web.

Connect your PlayStation 4 to the Internet

To make such a connection, you need to connect a network cable to the console and follow these steps:

  • Go to the settings of the game console and find there the options responsible for the network settings.
  • Click on the “Configure internet connection”.
  • Select the mode of using the network cable.
  • Click on the “Simple connection type”. In this case, the game console will independently determine the necessary network parameters and automatically connect.

If the TV works via a wireless connection, then in the Internet settings, select the available Wi-Fi connections from the proposed ones. After that, it will be enough to enter the password to connect to the Internet and start using the set-top box in real time. However, it should be borne in mind that with a wired connection, the game console will work much more productively, more stable and faster. This is especially true if the gambler downloads “heavy” Games that can take hours to load. It is very important that the network connection is NOT broken. Under the condition of a wireless connection, one-second failures often occur, which are enough for the downloaded game to not start.

The article covered ways on how to connect PlayStation 4 to laptop via HDMI. If the set-top box cannot be connected to the PC, then the easiest way is to use a TV equipped with a corresponding output.
