To connect the projector to a computer without problems, you need to determine in advance which cable you will have to use. VGA or HDMI. In the first case, the video will be displayed in the usual TV or DVD resolution, in the second. in high definition, HD or Full HD mode.
If you are just planning a purchase, it is worth clarifying how to connect an ACER or another brand projector to a laptop. It is best to use HDMI as it provides the highest picture quality.
Important: If there is no required port on one of the devices, you will have to resort to using an adapter. This reduces the image quality, but when watching movies or presentations, the difference is almost negligible.
Another problem can arise if one of the devices lacks both VGA and HDMI. This means that you will need to purchase a VGA-DVI adapter.
When connecting a laptop to the projector, it is important to remember that it is recommended that both devices be disconnected from the power supply before installing the cable. Plugging in to the outlet can only be done after the cable plugs have been inserted into the ports. First turn on the projector, then the laptop to ensure the correct display of content.
How the picture is displayed
After the device (Acer X118H) has been successfully connected, the image on the projected surface is displayed through the menu: “Display resolution”. “Multiple screens”. “Extend these displays”.
Windows 8 makes video output even easier. In the control menu, select “Display resolution”, then you just need to press the button for selecting the external screen.
When displaying a video or other image on a large screen, sometimes an unexpected problem may arise. the picture will not be very clear. This may be due to out of focus (you will have to adjust manually) or a dirty lens on the projector (you will need to wipe it with a microfiber).
Another problem may relate to the incorrect expansion, when the display shows a picture not in HD or Full HD, but in SD. Here the situation is corrected as follows: click on the right mouse button on the desktop. From the pop-up menu, select “Display”, after. “Screen Enlargement” and set the desired (for Windows 8 and 10. screen options). For other operating systems, the procedure is the same.
Instructions in 4 points on how to connect a projector to a laptop
The article answers the question of how to connect a projector to a laptop. This guide will help you avoid common difficulties and synchronize two devices in a few minutes. What is such a connection, and how to solve common mistakes. below.
Difference between laptop and computer connections
When using Microsoft operating systems, the principle of operation of a laptop and a personal computer itself is very similar. The only differences are in the hardware. If the user does not connect the projector to a laptop, you can use the instructions for connecting this device to a PC.
Important: Many modern laptop models lack not only VGA and DVI inputs, but even HDMI. Instead, there is mini HDMI and USB. This means that you have to use adapters.
Settings after connection
To connect the projector to your laptop without any difficulties, you just need to follow all the steps of the instructions in the correct sequence.
Most modern laptops have numeric keypads that let you start streaming videos or slides on a large screen with one click. The key is located in the F row (from F1 to F12 depending on the laptop manufacturer).
The button must be pressed simultaneously with Fn.
PC does not see the device
If the computer does not see the projector, the cause should be looked for, first of all, in the drivers. The problem is solved by installing them and then restarting the laptop.
How to connect a projector to a laptop, computer via USB
Modern projector models support USB connection. It has its advantages:
- one laptop can be connected to several video projectors at once, since USB connectors in computer equipment are usually provided from 2 to 4 pieces;
- connection for PC can actually be made, even if the HDMI and VGA video outputs are already occupied by other devices, you do not need to turn off the monitor first.
The physical space of the USB cable is very narrow, so the resolution of the data transfer suffers
At the same time, the disadvantage of USB connection is the almost inevitable loss of image quality. Also, users have reported communication problems when using too long USB cables.
The very connection of the video projector to the laptop is carried out in a standard way, the devices are connected with a cable through the appropriate connectors in the off state, and then they are put into operation. To establish a reliable connection, you need to download a special utility, you can borrow it for free on the website of the manufacturer of the external device.
How to connect a projector to a laptop, computer on Windows 10
The settings for different operating systems are very similar, but with minor differences. The difference is mainly in the names of tabs and actions.
To connect the projector to a Windows 10 laptop, you need to go to the “Action Center”, you can find it in the lower right corner of the screen. After clicking on the icon in the form of a message, a panel will open where you need to select the “Project” tab, and then. “Duplicate”.
For Win 10, the projection settings are accessed from the desktop
How to connect a projector to a laptop, computer on Windows 7
Windows 7 remains the most popular system on stationary and portable devices due to its simplicity and convenience. The diagram for connecting the projector to the computer is very simple, for this you need:
- go through the “Start” to the “Control Panel”;
- select the “Screen” section.
In the open window, you will be prompted to select several monitors and duplicate the picture from the main screen for them. The user will only have to apply this option, after which the settings will immediately change. You can also expand the image to only the first or second monitor.
The ability to configure multiple monitors in Windows 7 appears when the screens are connected successfully
A quick access scheme is also provided. You can simply click on the desktop and select Screen Resolution from the drop-down menu. After that, in the “Multiple screens” list, you will need to select the “Duplication” mode.
How to connect a projector to a laptop, computer on Windows 8
The easiest way to connect a projector to a Windows 8 computer is to swipe to the right of the screen. When the quick menu appears, you need to select the “Devices” item in it, then apply the “Transfer to screen” function, and then click on the “Duplicate” button. The image will be displayed on the main monitor and on the video projector at the same time.
You can quickly connect a second screen on Windows 8 by simply pressing the WinP combination
How to connect a projector to a laptop, computer via VGA
The VGA connector is slowly becoming obsolete, but is still common in computer hardware. It is easy to recognize it. this is a large nest, consisting of three lines of miniature holes.
The VGA cable has three rows of metal thin prongs
You can connect the projector to a laptop using VGA using the standard algorithm:
- the devices are turned off beforehand;
- the wire is connected to the projector, and then to the PC or laptop;
- both devices are included in the work;
- adjust the image output parameters.
The VGA cable is fixed by tightening the special built-in screws on the sides of the plug. If you forget to tighten them, contact may disappear at the most inopportune moment.
The disadvantage of VGA is that the cable will not be able to transmit sound simultaneously with the image. The laptop will have to be additionally connected to the speaker using a mini-jack cable.
How to connect a projector to a laptop, computer on Windows XP
The Windows XP operating system is quite rare because it is considered obsolete. But you can turn on the projector mode on a laptop through it. You need to call the quick menu and click “Options”, then select the screen on the “Display” tab and apply “Extend Desktop”.
You can enter the necessary settings on Windows XP directly from the desktop
How to connect a projector to a laptop, computer via HDMI
The HDMI digital interface is considered to be the most modern and the most preferred when using a projector. It provides the maximum data transfer speed from a laptop to an external device, respectively, and problems with the presentation occur less often.
By connecting the projector via HDMI, the chance of data loss or delay is minimized.
The algorithm is very simple. on the case of a computer projector and a PC or laptop, you need to find the appropriate connectors for the HDMI cable. As a rule, there should be a graphic or letter designation next to them. After that, the wire should be connected first to the video projector, and then to the laptop. If the connectors for the cable are different, you can use an adapter.
Installing the driver
HP Smart Install is available for select devices. In this case, you can connect the printer to your computer or laptop via USB and the installer will automatically start. Choose a Wi-Fi connection and follow the wizard’s prompts. HP Smart Install will set up a wireless connection on the printer and the USB cable can be disconnected (via the installation wizard).
You can find out if the HP Smart Install function is available in the instructions for your device. If your printer does not support this feature, you will need software for the device. It can be downloaded from Printerprofi.ru or from the website of the printing equipment manufacturer. How to download drivers from Epson official website and Hewlett-Packard.
Do NOT connect the device to your computer yet. Download the driver (preferably full), run and follow the prompts on the screen. During the installation process, the wizard will offer to select the type of connection. Choose wireless. over Wi-Fi. Follow the prompts and enter your network information (SSID and password) if necessary. This option is discussed in more detail in the article about setting up the HP LaserJet Pro P1102w over Wi-Fi.
This method is the easiest. The printer and router must support WPS (Wi-Fi Protected Setup) for setup. You can see if your equipment works with this function in the instructions. If WPS is supported by both devices, then you need to enable this function in one of the following ways:
- programmatically (through the printer menu and through the web interface of the router);
- hardware (by pressing a special button on the printer, and then on the router).
How to press, see the instructions. Sometimes you just need to press, and sometimes you need to press and hold for 2-3 seconds. For a more complete understanding of connecting a printing device via Wi-Fi to a router, watch the video below.
How to connect a printer to a laptop via WI-FI? | Your setevok
Without a doubt, the printer is a very convenient and useful device in the household. But this device is rather bulky, especially in comparison with a miniature netbook or tablet. And tying a mobile PC to a heavy stationary device using a “standard” cable connection is at least irrational.
Therefore, in this article, we will take a closer look at how to connect a printer to a laptop via WI-FI, as well as what to do if the printer does not see Wi-Fi.
And first of all, let’s dwell on the “classics of the genre”: how to make WI-FI out of an ordinary printer?
After all, agree that in order to configure a wireless connection between the printer and the laptop, both devices must support this function.
Connecting the printer via WI-FI router:
To do this, first enable the WPS function on your router, and then use the WPS (QSS) button to connect your printer to your home WI-FI network.
To print via Wi-Fi, it is enough to connect from your laptop to the installed printer via the local network (see the link at the end of the article).
To do this, run the “Search for available networks” in the printer control panel and select the network of your router by SSID. Here you will need to specify the password for Wi-Fi and confirm the connection to the network, after which the corresponding WI-FI indicator should light up on the printer.
Run the driver installation and select a WI-FI connection with manual configuration of the parameters, after which the printer will be available for a wireless LAN connection.
How to connect a printer to a computer via Wi-Fi network
Let the local (home) network consist of several computers connected via a WI-FI wireless network. And the question arose about how to add a printer (PU. printing device) to this configuration, so that it would be possible to print on it from any of them. Of course, you can connect it with a cable to a computer (laptop) and print documents from other PCs on it. But in this case, this computer must be constantly turned on, and even tied to a certain place, which is not always the most convenient. Modern wireless technologies make it possible to bypass these disadvantages, for example, by connecting the PU through a router with WI-FI. There are several ways to do this, which depend on the network configuration and the hardware and functionality that both the router and the printer have.
Method 1. using WPS
To use this method, connect the CP via a WI-FI router, it is necessary that both of these devices support WI-FI Protected Setup (WPS) technology. For most modern device models, this requirement is met. But just in case, this should be checked. The fact that this model of PU supports this technology can be seen by studying the instructions for it, or by contacting the website of its manufacturer. Now take a look at the bottom of the router. Here is a shortcut to which the WPS icon and PIN code should be applied, which will be needed when connecting the control panel:
But there may not be such a shortcut, in this case we will be convinced of WPS support by going to the web interface of the router. over, even if there is such a shortcut, you still need to do it in order to configure WPS. Depending on the model of the router, entering its interface is usually done by typing the address 192.168.0.1 or 192.168.1.1 in the address bar of the browser. Where the place with the WPS settings in the menu that appears after this is located also depends on the model of the router. For example, here is an excerpt from the menu of one of the D-Link router models:
Configuring WPS consists in setting the switch to the Enabled state. In addition, you need to specify the PIN of the router in the Device PIN parameter. You also need to make sure that the wireless network must be set to WPA or WPA2 security, but not WEP. it will not work. Also, in the router settings, you need to disable MAC filtering. Some printer models have a dedicated button to enable WPS. If there is one, it must be pressed and held until the device detects a wireless network. If one of the devices is equipped with a connection indicator, then after connecting it should light up.
How do I connect a wireless printer to my computer if the previous methods didn’t work? There is one more way, but it differs in complexity in comparison with the previous options. In such techniques, there are always nuances that can play a role in connecting devices. Most often they relate to the factory IP address and subnet mask, which is provided by the provider.
But such a situation is unlikely, and therefore it does not hurt to connect an MFP. This is due to the fact that most of the equipment does not use static addresses, but dynamic ones. For printing equipment of this kind, you just need to add the IP address available on the device in the computer settings. How to connect a printer to a laptop without a wire in this case? Follow the following scheme:
- We go to the control panel.
- We select the item “Devices and Printers”. “Printer Installation”.
- 2 items will appear in the window that opens. Here you will need to select the “Add a network, wireless or Bluetooth printer” block.
- The PC will start searching for suitable hardware automatically. When the MFP is found, it will appear on the screen.
- After that, you need to open the proposed block, where you need to enter the IP that the MFP has.
At the end of the connection procedure, a window will appear notifying you of successful pairing with the output device. You can start working with printing equipment immediately after restarting the laptop.
How to connect a WI-FI printer to a computer and laptop?
Of the “classic” ways to connect a WI-FI printer, you can note:
Connecting using WPS technology
Wi-Fi Protected Setup (WPS) makes it even easier to connect wirelessly via Wi-Fi.
Find a button on the router called WPS, press it and make sure that the corresponding indicator is on. Then do the same with the printer. If everything is done correctly, after about 2 minutes, the printer will automatically connect to your wireless network and be ready to print.
Preparing for the process
For example, prepare everything you need to implement the process. It is possible to bring an idea to life only if there are certain things. As a rule, all users have them. Anyway, after purchasing the projector for sure. Therefore, there are often no problems with preparation.
How do I connect the projector to my computer? This will require:
This is the most common inventory used to accomplish the task at hand. Additionally, you need to have a separate outlet to which the projector is connected.
How to connect a projector to a computer: instruction
You can connect a huge variety of devices to your computer. All PC users should be aware of the peculiarities of each process. Today we have to figure out how to connect a projector to a computer. In fact, bringing the idea to life is not as difficult as it seems. The main thing. know about some of the nuances of connection. What should users pay attention to? What will help bring the idea to life?
Instructions for working with VGA
The simplest connection is considered to be with a VGA cable. How to act in this situation? When the user has all of the above components, a certain algorithm of actions will need to be followed. over, no matter what operating system is installed on the computer.
How do I connect the projector to my computer? It is recommended to adhere to the following instructions:
- Place the projector in the right place.
- Connect the power cable to it and plug into an outlet.
- Take 2 VGA wires. Connect them to the projector.
- Insert one of the cables into the monitor, the other. to the system unit, instead of the monitor.
- Turn on the projector, then the computer.
- Install drivers for the connected device.
- Set the projector as a monitor in the operating system settings.
- Save changes.
It’s all. No further special action needs to be taken. Sometimes questions arise regarding how to expose a projector instead of a monitor in the operating system. But this will be discussed later. First, you should understand all the nuances of connecting the device.
Nevertheless, the listed methods are relevant only for stationary computers. You won’t be able to work with a laptop in this way. How to connect a multimedia projector to a computer?
It has already been said that you can use a wireless connection. In fact, there is nothing special or incomprehensible in the process. The main thing, again, is to follow a certain sequence of actions. This is the only way to fully implement the task.
To connect a computer to a projector (monitor), you need to do the following:
- With the equipment turned off, insert special USB signal receivers into the laptop, as well as into the projector.
- Switch on the equipment. As soon as the green light on the projector turns on, synchronization with the computer will take place.
- Install drivers for working with equipment. In Windows 7 they can be detected automatically.
- Install a program called “Connecting to a Projector”. It is usually found on the device driver disc.
- Run the installed software.
- Accept existing hardware settings.
Everything is easy and simple. Now it is clear what it takes to connect a projector. A computer (Windows 7 or any other operating system. This is not so important) must have a set of new drivers for the peripheral device. Otherwise it will malfunction.
You can also use an HDMI cable to operate the projector. This is a better way to transfer images. But how to connect a projector to a computer?
To do this, you will have to use the previously proposed algorithm of actions. The only difference to which it is recommended to pay attention. it is that the VGA cable will be replaced with HDMI. The rest of the instructions remain the same.
An important point is that you will have to work initially with the equipment turned off. Otherwise, there is a risk of malfunction and malfunction of the projector.
The first step is to understand that there are several options for the development of events. How do I connect the projector to my computer? The user can use the following connection methods:
- wired via VGA;
- wireless method;
- using HDMI.
Accordingly, the first option is used on stationary computers, and the second. on laptops. There is nothing particularly in the process. The main thing. to act correctly. How exactly?
Now a little about how to correctly display the data from the computer on the projector. It is important to know about this feature. Otherwise, the projector will be connected, but it will not work.
As a rule, the user should adhere to the following actions:
- Start the operating system.
- On the desktop, right-click on any free area.
- Select “Screen Resolution” in the list that appears.
- In the “Screen” section, mark “Screen 2, projector”. The inscription may be different, but the meaning does not change.
- Save changes.
After that, the image should be transferred from the computer to the connected equipment. It doesn’t matter if the user has Windows 7 or Windows 10. How do I connect the projector to my computer? From now on, the answer to this question is clear. In reality, everything is not so difficult. The main problems can arise precisely with the output of the image from the computer to the projector. But fixing the situation is not difficult.
How to connect a projector to a laptop via HDMI
As you know, the HDMI interface allows you to connect devices “hot”, i.e. already on. But we do not recommend doing this, because there is a high probability of static charge from clothing to disable the ports of the devices. Therefore, before you insert the plug into the connector, remove the charge from yourself by touching something metallic and massive with your hand. After that, connect the cable to the laptop and the projector, and then turn on the power of both devices.
A laptop is, in general, an ordinary PC with a built-in monitor. By default, the video system displays the image on it. At the same time, either a video card built into the processor is used, usually for working in office applications and a browser, or a discrete (separate) one, if the laptop is equipped with it, which is used in 3D games.
The system in the laptop itself determines which video card should be used, depending on the type of load. It is usually the built-in video card that is used to display the image on the projector. Accordingly, its performance will be significantly lower than discrete. This should be taken into account when broadcasting images of games to the projector and, if necessary, in the proprietary utility from the video card, forcibly indicate which video card to use.
In order to enable the transmission of video from the screen to the projector in Windows 10, you need to enable either the use of multiple displays in the OS settings, when a copy of the laptop screen will be displayed on the projector canvas, or simply use the projector as an external monitor. In the latter case, the image on the built-in display will not be displayed. But as soon as you disconnect the HDMI cable or turn off the projector, the image transmission to the built-in monitor will be restored again.
To activate the transfer of the image to the projector, go to the menu “Start | System | Display | Multiple Displays ”and click the“ Detect ”button. After the laptop detects the connected projector, you will be prompted to use either a scheme with image duplication, or select one of the devices as the main one. In most cases, the scheme with duplication is the most optimal, but if you watch, for example, a movie, it is better to blank out the image on the built-in display.
There is also a faster way to display images from a laptop to a projector. To do this in Windows 10, use the WinP keyboard shortcut. In this case, a vertical menu curtain will appear on the right side, where you can immediately select the type of image output to the second display or projector. Here you will see “Computer only” and the image will not be output to the projector; “Duplicate”, then a copy of the screen will be displayed both on the computer screen and on the projector; “Expand”, while the desktop extends to the projector, the right one will be shown through the projector, the left one on the laptop screen, “Projector only”, so everything that happens on the screen will be displayed only on the projector.
It should be noted that most laptops have a special function key that allows you to quickly switch to displaying an image through a projector. It is activated by simultaneously pressing Fn F1 (display | monitor) on the keyboard. Different manufacturers may assign this key to their own buttons.
How to connect a projector to a laptop: step by step instructions
Laptop and projector are made for each other. After all, from a small laptop you always want to get a huge image displayed through a projector. How to connect it quickly and without special settings. in our workshop
Displaying an image from a laptop to a projector is not difficult at all if you make some preparations in advance and take care of a special interface cable. Most modern laptops have a standard HDMI connector, which will work just fine with a regular HDMI cable. This is currently supplied with any consumer electronics. However, you should still make sure of this by looking at the left side of the laptop case (for most models, the HDMI connector is located there). In some devices, the video signal is output through the mini-HDMI connector and even micro-HDMI, which is due to the small thickness of the case.
Accordingly, to set up a projector on a laptop, you need a mini-HDMI to HDMI or micro-HDMI to HDMI cable. The latter is also used to connect an action camera (including a GoPro) to a TV. When buying, it is also worth considering the required cable length. For example, if the projector is to be mounted on a ceiling, the cable must be at least 2.5 meters long.
If a cable connection is not possible, you can connect the projector to a laptop using a wireless Wi-Fi connection. But for this it is necessary that the projector itself be equipped with a Wi-Fi module, or you need to connect a special Wi-Fi dongle to the projector via the HDMI connector. But it is worth remembering that this device is powered through the USB port available in the projector. We will tell you more about this below.
Displaying the image to the projector via Wi-Fi
On a Windows 10 laptop, go to Start | Parameters | System | Display ”and on the right side under“ Multiple displays ”click on“ Connect to a wireless display ”. A vertical shutter with the “connect” menu and a list of detected devices will appear on the right side.
In our case, this is Samsung 6 series (49), but to connect to a projector, a corresponding display device, for example, a Wi-Fi dongle, will appear in this list. Click on the selected model, then on the wireless device itself, agree to the connection request. It should be noted that the connection may not happen on the first or even on the second attempt, since the computer needs time to transfer the signal encryption keys to the dongle. But after it is connected to the laptop via WI-FI, you can broadcast the video even from another room.
We display content in the desired mode
Theoretically, after connecting the cable to the appropriate connector, the picture should be displayed automatically. In some cases, when the settings are incorrect, the user must himself make the necessary changes to display the content. It is known that each version of the operating system has its own characteristics, therefore there is no single order of actions.
- Hotkeys. To project the menu from the laptop onto the external screen of the projector, you need to combine with one press of the Fn key and one of the F1-F12 series (the button with the image of the laptop and the external screen). This method does not work if the function buttons are not active.
Button to switch between laptop screen and projector
Then, the user has access to four display modes of the connected projector.
- Duplicate (repeat). when a video from a computer or laptop is duplicated to an external screen.
- Computer only. the content is played on the laptop display, and the external screen is not involved at this time.
- Expansion. the desktop is divided into two, the left side is displayed on the PC monitor, and the right side through the projector.
- Projector only. information will only be projected on the big screen.
Methods for connecting a video projector to a laptop
Connecting the projector to a laptop is carried out by simple manipulations, but, unfortunately, difficulties are often encountered along the way. When the devices refuse to pair automatically, this means that the standard system settings are knocked down, or these devices simply “do not understand” each other. How do I connect the projector to my laptop in this case? The connection is configured manually: for this, the operating system provides certain sets of keys. In the absence of such, parameter setting is carried out by forced configuration changes.
A multimedia projector, regardless of model, connects to a computer or laptop via a VGA or HDMI cable. For high quality content, HDMI will be preferred.
- disconnect both devices from the mains before turning on the projector;
- insert the plug into the corresponding socket;
- turn on the projector, then the computer.
In cases where the required connector is not available, a special adapter can be used. This can happen when the video card has only a DVI connector, and the projector has VGA or HDMI. The use of an adapter insignificantly reduces the quality of the content. The projector is turned on first, otherwise the computer cannot see it.
You can also synchronize devices via the Wi-Fi protocol, today this method is gaining popularity. To activate, you need to install drivers, but in the case of Windows 7, usually, regular ones are enough.
If the disc is lost, the application can be downloaded on the Internet from the projector brand website.
Before connecting the projector to a laptop, you need to install the Wi-Fi antennas in the USB connectors of the projector and PC, outwardly they resemble a small USB flash drive. The green indicator light informs that the connection was successful.
It is worth noting that not all projectors that support Wi-Fi will project video. Some models can be connected only to control equipment, this nuance needs to be clarified even when purchasing. A wired connection is more reliable and practical: HDMI plug, for example, is designed to transmit excellent quality video without interference.
Useful tricks for Power Point
Office program Power Point is “sharpened” for presentations, it is often used because it is simple and convenient. It has its own peculiarities of work, for example, you can display slides on a large screen, and the text of a report or lecture on a PC display.
The settings do not take much time: after synchronizing the projector with the PC, go into the program and look for “Slide Show”. “Show Presentation” on the top panel. We put a tick in front of “Projection equipment”. Here you can find the “Presenter Mode”, if you activate it, various auxiliary tools for conducting lectures will be displayed on the screen. additional buttons or notes.
Manual image debugging
Sometimes pictures or letters are blurred or “float”. this happens when the wrong monitor resolution settings are set on the PC. To maximize the quality, set the resolution on your computer to match the specifications of the projector. This does not change the projector settings.
How to change settings on PC / laptop (for Windows 7 / Vista platform):
Windows 10 settings are slightly different, here the item “Resolution” is located in the section of the display settings. Click on “Start” and find the “System” tab, on the right side of the window, scroll all the way down and open “Advanced display settings”. Then everything is simple: select the desired value and save the settings.
This completes the task of how to connect the projector to the computer. After connecting, the user only has to choose a convenient output mode for a presentation or home video viewing.
Correct connection of the projector to the laptop
A multimedia projector is a device that projects an image from source (laptop, computer) onto a separate screen or interactive whiteboard. This type of technique is mainly used in classrooms (conference rooms and similar places) to show presentations or other multimedia content. It is very easy to connect the projector to a laptop or computer, and the process itself takes only a few minutes. Popular are video projectors from companies such as Benq, Asus, Acer, Optoma, Sony, Epson, Vivitek, etc. The methods and features of their connection to a PC, as well as adjusting the image, will be discussed in this material.
Possible problems and ways to solve them
If there is no image on the external screen after connecting the video projector to the signal source, the reasons may be as follows:.
- The projector will not connect to a PC or laptop because the wire is not properly connected to the connector. To fix the problem, you need to check the contacts or reconnect the equipment.
- The wrong input is selected on the projector, so the device cannot see the source. The solution is to select the correct input using the remote control or the button on the video projector body.
- The multimedia content is not displayed by the projector because only the PC (laptop) is installed in picture modes. In this case, using the “hot” or function keys, you should select duplication or expansion.
So, connecting a projector to a computer or laptop is very simple. It is enough to connect the devices using a cable or Wi-Fi antennas, turn them on to the network and, if necessary, adjust the image. If everything is done correctly, then problems with image transfer are excluded.
Typically, the projector is connected to the image source using a VGA-VGA cable. If there is no VGA connector on one of the devices, but there is DVI, then you will need to additionally purchase a VGA-DVI adapter. But it should be noted that this will slightly degrade the quality of the transmitted signal.
You can connect the projector to a PC via an HDMI cable if both devices have such an output. Such a connection will provide the highest quality image transmission to the large screen. To do this, you need to connect the devices with the selected wire, then turn them on in turn, the first is the video projector. After the signal source is working, the transmitted content will appear on two screens.
Nuances for PowerPoint
Typically, presentations are shown through the Power Point program included in the Microsoft Office suite of applications. It can also be used to customize the output of the image to the secondary screen. To do this, open the “Slide Show” and go to the “Presentation settings” tab. In the field “Multiple monitors” you need to select the connected equipment. Now the presentation will be broadcast through an additional screen, while on the main one you can deal with other tasks.
Advice! If you select “Use Presenter View”, additional elements will appear on the screen: transition to the previous and next slide, time, notes, buttons for ending the presentation and turning off the image.
Connecting the Projector
There are two ways to connect the projector to a signal source: with and without a cable. That is. by wired and wireless connection.
