How To Make A Screen Through HDMI
Connecting a TV to a Computer
The first thing to start with is choosing a cable. It is required to inspect the back of the system unit and determine which free outputs are present on it.
Description of connectors on the PC card
Then the same thing needs to be checked on the TV. It is required that the same connectors are free on the computer and on the TV. If both ports are free, then it is better to give priority in favor of the HDMI connector, since it has a higher bandwidth, and, therefore, better quality. In addition, when connected via HDMI, not only the image is transmitted, but also the sound.
If the computer will be connected to the TV via the VGA connector, please note that on most modern TVs, when connected via this output, the screen resolution will be significantly lower than the “native” TV resolution, which will negatively affect the image quality. In the characteristics of the TV, the screen resolution is always indicated separately when connected via the VGA connector.
After the computer and the TV are connected with a cable, it remains only to indicate on the TV from which connector to receive the image (usually the source button).
Configuring Windows 10
Unlike older versions of the operating system, Windows 10 is the most convenient for working with Multiple Displays. There are three ways to mirror your computer screen to TV in windows 10.
The first way is the easiest. To turn on the computer, you must simultaneously press the keys “Windows” “P”. This combination allows you to switch between two-screen computer modes. It remains only to select the desired mode.
If keyboard shortcuts are confusing to the user, you can use Windows Action Center. In the lower right corner of the screen, you need to click on the corresponding icon. A window will open in which you need to select the item “sent to the screen”. In the appeared menu “Project” select the item “Repeating”.
Enabling Screen Mirroring in Windows 10
If the TV screen resolution is higher than the monitor screen resolution, the picture on the TV display will be centered, surrounded by black borders. In this case, you need to use the following method.
On the desktop, in an unoccupied place, click the right mouse button. A context menu will open, in which you need to select the “Display settings” item. In the window that opens, you need to find the item “multiple displays” and click on the pop-up menu. In it, select the item “Duplicate screen“. After that, be sure to select a TV (screen 2) and check the box “make the main display”.
Mirroring your computer screen to your TV
There are NOT rare situations when the monitor size is not enough for comfortable work with a computer. In this case, the computer is connected to a TV or projector and the image is displayed on it. But what if you want the picture to be displayed both on the main computer screen and on an additional TV connection to it? In this article we will show you how to duplicate a screen from a computer to a TV in windows 10. This will require:
- Computer with an unused VGA or HDMI connector
- Cable connecting computer and TV
- TV with the above connectors
From all of the above, we can conclude that connecting a computer to a TV is not so difficult. The main thing is to follow the instructions and everything will work out. This manual is also relevant for connecting projectors and other devices for displaying images from the computer screen.
Diagnosing interface problems
If there are problems with displaying images through this connector, then it is logical to assume that the HDMI port on the laptop is not working. However, it is worth rushing to conclusions, since there are several “symptoms” breakdowns that need attention Pay attention.
The first, and most obvious, sign of a breakdown will be the disappearance of the image on the TV or monitor. First, it is worth checking the connection, and if the laptop detects it, then it is recommended to inspect the cable. First, it must be tight “sit” in both slots. Secondly, you need to Pay attention to its entire length: there are no kinks, external damage. Thirdly. kind of port. it is often possible to confuse the input / output of the jacks, since several of them are installed, especially in TVs.
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.
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 the card, and from it you need to connect to the 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, press 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.
In order to purchase a suitable cable, you need to understand how to find out which HDMI is on a laptop. To do this, you need to consider the characteristics of the card, since it is responsible for this output.
If the card is discrete, then you should visit the manufacturer’s website and view the detailed characteristics of the card, or rather. her outputs. In laptops this will be seen in their specifications.
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. By replacing the analog connection method, HDMI facilitates the transfer of high quality 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 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 connection.
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 choose an orientation. landscape, multiple 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.
Connecting laptop to laptop
Now we can consider a method of how to connect a laptop to a laptop via HDMI. In fact, connecting two laptop computers this way will do nothing. The fact is that the HDMI connector on a laptop is designed only for data transmission, but not for receiving.
For such cases, there is an RJ-45 connector as well as a wireless Wi-Fi connection. So it will NOT work to connect a laptop to a laptop via HDMI. Some laptops have a built-in Bluetooth adapter, which can also be used to connect laptops to each other.
How to enable HDMI on a laptop: simple instructions and recommendations
Nowadays, it is becoming more and more popular to transfer data from one device to another, bypassing portable drives. One such method is an HDMI cable. Here’s how to enable HDMI on a laptop.
The versatility of this type of cable is so popular that it can be used to:
- Connect TV to Computer.
- Transfer data from laptop to monitor.
- Connect smartphone to TV or monitor.
- Make a connection between the card and the monitor (or TV).
- Play movies and music using one high quality cable.
It is becoming easier to connect an equal device to the second, which is why the HDMI interface is so popular. Nowadays, there are practically no devices in which this port would be absent. In some cases, you can use adapters, for example, to connect your smartphone to a monitor or TV. Only the image that is broadcast from the source device will be displayed.
For example, if you connect the system unit to a laptop, you will need a card port and a laptop port. The main thing. Do not mix up the input and output connectors, otherwise the image will NOT appear.
If the sound signal is lost, visit the “Control Panel” and the Hardware and Sound tab. Next, we only need “Sound”, a window will open where you can choose from connection options. If the problem is with a stationary computer, then you need to choose a card, and in the case of a TV, respectively, a TV. After that we press “Apply”.
You should NOT exclude the problem with the port itself, as it could simply burn out. To prevent such a disaster, it is necessary to disconnect extraneous connections before connecting HDMI: cable TV and a satellite dish. Checking the outlet will also not be superfluous. its grounding plays an important role. If the connector burns out, contact the service center to replace the connector.
If the laptop has HDMI?
If the laptop has an HDMI port, then the only output is the use of special signal converters from HDMI to VGA or DVI.
But in practice, if a discrete adapter is used, then most likely the output of a third-party image to the built-in display will be blocked (since in such laptops there are 2 cards that switch among themselves depending on the load on the graphics subsystem).
How to connect?
It is recommended to adhere to the following aLGorithm (for example, Windows 7):
- Turn off PC and laptop.
- Connect one end of the HDMI cable to the laptop, the other to the HDMI output on the adapter (not to the monitor).
- Turn on PC and laptop.
- On the PC, enter the “Control Panel”, open the “Display” menu, go to the settings.
- In the drop-down menu “Multiple screens” select “Extend desktop” (or duplicate, create a new table. it all depends on the needs of the user).
- On a laptop, also go to the “Screen” settings and select “Show Desktop 1” (or “PC Monitor”. the parameter may be called this way, depending on the brand). After that, the display will show the image from the PC.
- In most modern laptops, switching between operating modes of the integrated display can be performed using hotkey combinations. The most common combinations are FnF4 and FnF8. You can clarify in the technical documentation or on the label on the keyboard itself.
How to set up multiple displays in Windows is covered in the following:
Similar settings for image output can be set using proprietary graphics accelerator software (NVidia, AMD, Intel, SiS). over, in many cases there are more functions. For example, in software from NVidia You can not only configure the output of an image to a third-party display, but also at the same time adjust its brightness, contrast, or even turn on “portrait orientation” Displayed images.
After connecting the laptop to the PC via HDMI, the sound is automatically transmitted along with the signal, and the audio card built into the PC is turned off. You can change this parameter in the “Control Panel”, in the “Sound” tab (by choosing the built-in audio codec instead of HDMI). Otherwise, the sound will not be output to the headphones or PC speaker.
Likewise, you can use your PC monitor as an additional or external display for your laptop. But in this situation, it will be easier to simply connect the monitor directly, bypassing the graphics accelerator of the personal computer.
HDMI is a digital I / O port that supports bi-directional communication. Its operation is controlled by the adapter driver. Accordingly, the first step is to update the software to the latest current version (to support the latest version of the port specification).
Some Ultrabooks that have a physical HDMI port will not be able to output images from another PC. This is explained by the technical limitations of the used chipset and its strapping on the motherboard.
One more nuance: you should connect with the equipment turned off (both notebook and PC). When you try to connect them “hot” there is a considerable probability of failure of the graphics accelerator (or chipset, if integrated graphics is used). Only after disconnecting the device can you connect and configure.
How to output an image to a laptop via HDMI in 5 minutes
A laptop is a portable PC. But the principle of its technical structure is similar. This means that its display can be used as a second monitor for a PC.
But how can this be done? How to connect a laptop to a computer as a monitor via HDMI and are there any other options for how you can display an image from a PC on a laptop display?
- Technical information
- How to connect?
- If the laptop has HDMI?
- What other options are there for displaying images?
What other options are there for displaying images?
It is possible to display an image from a PC to a laptop display not only through a cable, but also wirelessly. But only if each device has a compatible Wi-Fi adapter supporting the WiDi or MIRACAST function.
Alternatively, you can consider programs such as TeamViewer, AirDisplay (There are not only for Windows, but also for Mac OS) Radmin. They also allow image transmission via Wi-Fi (even if there is no WiDi support, the image quality will be low), but if there is a network connection (via a router or switch).
In total, if you have an HDMI cable, the laptop display can be used as an additional or duplicate monitor. And it works regardless of the version of the built-in HDMI port specification. In the absence of HDMI, you can use either wireless image output (WiDi) or a dedicated HDMI to VGA or DVI converter.
When connecting a laptop to a TV via HDMI, there is sound, but there is an image
If everything seems to be working, but there is no sound, and no adapters are used, and this is just an HDMI cable, then try to check which playback device is installed by default.
Note: if you use any version of the adapter, then Considering that VGA sound cannot be transmitted, regardless of whether this port is on the side of the TV or laptop. The sound output will have to be configured in some other way, for example, to the speaker system through the headphone output (do not forget to set the appropriate playback device in Windows, described in the next paragraph).
Right-click on the speaker icon in the Windows notification area, select Playback Devices. Right-click on an empty spot in the list of devices and enable the display of disconnected and disconnected devices. Note if there is an HDMI device listed (there may be more than one). Click on You need (if you know which one) with the right mouse button and set “Use as default”.
If all devices are disabled or there are HDMI devices in the list (and they are also absent in the section of sound adapters in the device manager), then it is quite possible that you do not have all the necessary drivers for the motherboard of your laptop or for the card installed, they should be taken from the official laptop manufacturer’s website (for a discrete card. from its manufacturer’s website).
How to connect a laptop to a TV
In this article, we will talk in detail about several ways to connect a laptop to a TV. both using wires and using a wireless connection. Also, the instructions will be on how to set up the correct display on the TV connection, which of the options to connect it is better to use in other nuances. The following are ways of wired connection, if you are interested in wireless, read here: How to connect a laptop to a TV via Wi-Fi.
Why might this be required? I think everything is clear here: playing on a TV with a large diagonal or watching a movie is incomparably more pleasant than on a small laptop screen. The instructions will cover both Windows laptops and Apple Macbook Pro and Air. Connection methods include HDMI and VGA, with the help of special adapters, as well as information on wireless connections. May also be helpful: How to fix poor HDMI picture quality.
Attention: it is better to connect cables with switched off and de-energized devices in order to avoid discharges and reduce the likelihood of failure of electronic components.
Typical problems when connecting a laptop to a TV via HDMI and VGA
When you connect your laptop to your TV using wires, using HDMI or VGA ports (or a combination of both, when using adapters / converters), you may find that all of this does not work as expected. Below are typical problems that may arise and how to solve them.
wired connection options
In addition to HDMI-HDMI, you can use other wired connection options to output images from your laptop to your TV. Depending on the configuration, these may be the following options:
- VGA. VGA. With this type of connection, you will have to separately take care of the sound output to the TV.
- HDMI to VGA. if your TV only has a VGA input, then you will need to purchase an appropriate adapter for this connection.
You can assume other options for a wired connection, however, I have listed all the most common ones that you are likely to come across.
Problems with cables and adapters when connecting
It should also be borne in mind that very often problems with connecting to TV (especially if the output and input are different) are caused by poor-quality cables or adapters. And it happens Not only in quality, but in a misunderstanding that a Chinese cable with different “ends” is usually an inoperative thing. Those. you need an adapter, for example this: HDMI-VGA adapter.
For example, a common option. a person buys a VGA-HDMI cable, but it does not work. In most cases and for most laptops, such a cable will never work, you need a converter from analog to digital signal (or vice versa, depending on what is connected to what). It is only suitable for cases when the laptop specifically supports digital output via VGA, and there are almost no such.
Connecting Apple Macbook Pro and Air Laptops to a TV
Apple laptops are equipped with a Mini DisplayPort output. To connect to your TV, you will need to purchase the Corresponding Adapter, depending on what inputs are available on your TV. Available on the Apple Store (and found elsewhere) include the following options:
- Mini DisplayPort. VGA
- Mini DisplayPort. HDMI
- Mini DisplayPort. DVI
The connection itself is intuitive. All that is required is to connect the wires and select the desired image source on the TV.
Sun signal or just images from laptop on TV
If this problem appears, if you have Windows 10 or 8 (8.1) installed, try pressing the Windows keys (with the logo) P (Latin) and select “Extend”. The image may appear.
If you have Windows 7, then through the right click on the desktop, go to the display settings and try to define the second monitor and also set “Extend” and apply the settings. Also, for all OS versions, try to set for the second monitor (provided that it is visible) the resolution that it exactly supports.
Connecting a laptop to a TV via HDMI is the best way
Almost all modern laptops have an HDMI or miniHDMI output (in this case, you will need an appropriate cable), and all new (and not so) TVs have an HDMI input. In some cases, you may need adapters from HDMI to VGA or others, in the absence of one of the types of ports on a laptop or TV. over, ordinary wires with two different connectors at the ends usually do not work (see below in the description of the problems of connecting a laptop to a TV).
Why HDMI is the best solution for connecting a laptop to a TV. Everything is simple here:
- HDMI is a digital interface that supports high resolutions, including FullHD 1080p
- When connected via HDMI, not only the image is transmitted, but also the sound, that is, you will hear the sound through the TV speakers (of course, if this is not necessary, you can turn it off). It may be useful: What to do if there is no sound via HDMI from laptop to TV.
HDMI port on laptop
The connection itself is NOT particularly difficult: We connect the HDMI port on the laptop with the HDMI input of your TV with a cable. In the TV settings, select the Corresponding signal source (how to do this depends on the specific model).
On the laptop itself (Windows 7 and 8. In Windows 10, it’s a little different. How to change the screen resolution in Windows 10), right-click on an empty space on the desktop and select “Screen resolution”. In the list of displays you will see the newly connected monitor, here you can configure the following parameters:
- TV resolution (usually, it automatically determines the optimal one)
- Options for displaying images on a TV. “Expand screens” (different image on two screens, one is a continuation of the other), “Duplicate screens” or display the image only on one of them (the second is disabled).
In addition, when connecting your laptop to a TV via HDMI, you may need to adjust the sound as well. To do this, right-click on the speaker icon in the Windows notification area and select “Playback Devices”.
In the list, you will see Intel Audio for Display, NVIDIA HDMI Output, or another option that matches HDMI audio output. Set this device as default by right-clicking on it and selecting the Appropriate item.
Many laptops also have special function keys in the top row to enable output to an external screen, in our case, a TV (if such keys do not work for you, then not all official drivers and utilities of the manufacturer are installed).
It can be FnF8 keys on Asus laptops, FnF4 on HP, FnF4 or F6 on Acer, I also met FnF7. Keys are easy to identify, they are labeled as in the image above. In Windows 8 and Windows 10, you can also enable the output to the external TV screen using the WinP keys (works in Windows 10 and 8).
Wireless connection of laptop to TV
Update 2016: I wrote more detailed and up-to-date instructions (than what follows) on connecting a laptop to a TV via Wi-Fi, i.e. wirelessly: How to connect a laptop to a TV via Wi-Fi.
Modern laptops with Intel Core i3, i5 and i7 processors can connect wirelessly to TVs and other screens using Intel Wireless Display technology. As a rule, if you have NOT reinstalled Windows on your laptop, all the necessary drivers for this are already there. Wirelessly transmits Not only high-definition images, but also sound.
To connect, you will need either a special set-top box for the TV, or support for this technology by the TV receiver itself. The latter include:
- LG Smart TV (not all models)
- Samsung F-series Smart TV
- Toshiba Smart TV
- Many Sony Bravia TVs
Unfortunately, I have no opportunity to test and demonstrate how it all works, but Detailed instructions on using Intel WiDi to wirelessly connect a laptop and ultrabook to a TV are on the Intel official website:
I hope that the methods described above will be enough for you to be able to connect your devices in the right way.
How to connect a projector to a laptop or computer
Any PC user can connect the projector to the device. You don’t have to be an expert in this area. There are several ways:
- Wired connection via VGA, HDMI, USB ports.
- Wi-Fi wireless connection.
To connect the devices with each other, you need to make sure that both are in full working order. Be sure to check all connectors, cables and drivers available in the computer or laptop. A driver is a special software that helps to connect a device to another. As a rule, to set up a projector on a laptop or computer, the drivers already available in the equipment are used. But sometimes you have to download them from the Internet for free or together additionally.
Configuring Windows XP
The connection program for this device is the same. However, the concurrent display process is slightly different.
You don’t need to go into tools and taskbars for this. All work is just a right click on the desktop. Next, select the function parameters.
For the monitor to work, you need to name it with the mouse and select the item “extend the desktop to this monitor”. In this case, you must also check that the screen resolution matches the resolution of the projector and, if necessary, set it.
After the end of the presentation, you should return all the settings back, otherwise the font on the desktop will go beyond the screen and you will be uncomfortable working on it.
It is worth noting that the wired connection will be the most effective. In this case, a more stable connection and almost no technical problems are guaranteed. The projector will definitely not hang up, and depends on the Internet.
Programs for working with projectors
Very often, when working with a projector, they use the Power Point program. Using it, you can enable the presenter’s method, where part of the information will be displayed on another device and will be visible only to the presenter.
The Notes feature allows you to make additional notes. That allows NOT to memorize the entire performance. Pen or laser pointer highlight certain important elements.
Also, using the program, you can View all slides at the same time or, conversely, change the size of the slide.
Sometimes, when using small laptops, it is necessary to download the Projector Dedicated Apps, such as for mobile phones. For the monitor to work separately or together with the desktop in THESE applications is configured separately.
Configuring Windows 10
It is possible to connect the projector to a windows 10 computer using the same methods described above. With the correct connection, usually the image is automatically displayed immediately on the screen, it may NOT be clear and floating. It is necessary to adjust the resolution, set it in the computer settings in accordance with the resolution of the projector.
The display system is the same as on windows 7. The only difference is in the names. Instead of Duplicate, there will be Duplicate, only projector or only screen.
How to connect a projector: clear instructions for eliminating all difficulties and problems
When buying a projector, instructions are usually included in the kit, according to which it can be easily connected to a computer or laptop. But sometimes, due to the absence of any programs, this process requires additional settings. Difficulties and problems largely depend on the technical characteristics of the connected device.
- How to connect a projector to a laptop or computer
- wired connection
- What is VGA connection
- HDMI connection
- USB connection
- Wi-Fi wireless connection
- How to set up the projector so that the image is displayed on the monitor and on the projector
- Configuring Windows 7
- Configuring Windows 10
- Configuring Windows XP
- Programs for working with projectors
- How to turn off the projector
Configuring Windows 7
When connected to windows 7, the control panel opens in the general menu and the “hardware and sound” section is selected. Next, a window will appear where four ways to reproduce the image are registered:
- Show presentation to projector only.
- Desktop shows the interface to output to the projector and monitor screen.
- Shows only the desktop.
- Shows the desktop on both the screen and the projector.
When you select any parameter, its data starts working immediately. When you change the settings, you must re-enter these sections. Therefore, in order to quickly switch between modes, it is recommended NOT to close the panels, but only to minimize them to the lower toolbar.
Wi-Fi wireless connection
Modern Internet connections with fast and high-quality wi-fi allow you to completely exclude wired connections from use and use the World Wide Web. There may be several reasons for this:
- the room does NOT involve the use of cords;
- a large number of wires get in the way and there is nowhere to hide them;
- an urgent additional connection of mobile devices is required at the event;
- a road presentation requiring an operational organization;
- during training, when all devices are connected, be able to control the process of performing tasks.
Wi-fi can be used in two ways:
- via the Internet connection of the organization in which the presentation is held or
- use projectors with support for wi-fi communication, which itself is its source.
To use the projector, it must first be properly charged and installed on a secure tripod. Next, we adjust the quality and size of the image on the screen. PC in the settings, select the hdmi system, connect to the wi-fi router in the parameters section.
Connecting the projector to a laptop or computer via hdmi is by far the most reliable connection for displaying an image on the screen.
An important advantage of this connection is the simultaneous transmission of image and sound, which allowed NOT to use additional wires. technological, it transmits sound and picture with the maximum expansion and has additional protection against piracy. Thanks to this cable, it became possible to output a better image through the projector.
How to connect a laptop to a TV
Connect laptop to TV via HDMI cable.
- Connect the cable to the HDMI output of your laptop.
- Insert the other end of the cable into the HDMI input of your TV.
- On the remote control of your TV, press the button responsible for selecting the source of the displayed signal.
Today’s flat panel TVs, like computers, are digital devices. Via HDMI, it became possible to transmit high quality files simultaneously with sound transmission.
High-Definition Multimedia Interface or abbreviated. HDMI, in translation: high definition multimedia interface. Most cards provide the ability to connect a computer to a TV via hdmi.
How to connect a TV to a computer via HDMI. How to connect HDMI to TV
shutdown. I turn off both devices so as NOT to burn the ports. Connect your computer (laptop) to the TV using an HDMI cable. Plug one end of the cord into the HDMI out of your computer and the other end of the cord into the HDMI in of your TV. To avoid degrading the picture and sound quality, do not connect the DVI output (via an adapter) of your computer to the TV HDMI input, and vice versa. The connectors must be the same.
Loading. The cable is inserted. Turn on your TV and computer. The computer will boot into Windows. It will become clear that the TV is connected to an external source by a slight blinking of the screen. Do not forget to put the TV in AVI mode, it receives signals from an external source (connected computer), and not from an antenna. In AVI source mode, select Corresponding HDMI input of TV.
customization. To connect your laptop or computer to the TV, adjust the picture. On the computer desktop, right-click the context menu.
In Windows XP, select Properties, click the Options button. Click the “Advanced” button, select the appropriate value. The TV screen displays your computer desktop.
With Windows 7 and Windows 8 installed on your computer, right-click on an empty space, select “Screen Resolution”. Find the term “Screen” and choose the appropriate option. The connected TV was NOT automatically detected? In the same window, click the “Find” button.
Wait for the TV search to finish. Set the maximum scanning resolution by selecting in the tab “Monitor” and “frequent screen updates”.
Up in “Screen settings” we determine which screen we have the main (1st) and additional (2nd).
Must click “Define”. You will see the number on the TV screen “1”, on the computer / laptop screen the number “2”. To rectify the situation, in the window “Screen Resolution” click on the screen “2”. Tick “Set as primary monitor” and click the “Ok” button.
If necessary, in the properties of the map, adjust the resolution of the desktop size, color correction.
Reboot. Restart your computer. Changes to settings will happen automatically.
People often write to me: “Connect HDMI, and the sound comes from the laptop. What to do? »Now I will tell you several ways that even beginners can cope with. But first, I recommend reading the article. in the correct connection.
Installing the driver
It happens rarely, but if you installed the adapter driver in manual mode and accidentally unchecked (tick) the HD Audio component, then this is why there is no sound on HDMI on the TV:
- Open the device manager via Control Panel or the main context menu (Win X) and go to the section of sound, game devices.
- If the list contains only one component (sound card), then the problem is really in the driver. But if there are several options, for example, NVIDIA HDA, then use the right-click menu to select the “enable” command to turn on the desired device:
- Now I will tell you how to install the missing driver. First you need to go to the official website of the adapter manufacturer and download the current version of the “firewood”.
- After starting the installer, be sure to select the manual installation mode in order to control the process and see all the installed components. Pay attention to the mark next to “HD Audio Driver”. Let’s take an example from NVIDIA:
You must restart your computer for the changes to take effect. By the way, the Driver Booster utility, in which I told earlier, will help to simplify the update procedure.
Change the playback device
There is sound when connecting a laptop via HDMI. this is a common phenomenon that can occur if the system does NOT automatically detect the connected device. You should check your Windows audio settings:
- Opening the control panel (Through the Win X menu) and there we go to the “Sound” section, having previously selected the “Small icons” view mode. You can make it easier. they will right-click on the speaker image, which is located near the active language indicator in the notification area:
- We select the item “Playback devices” and view the list of fixtures in a new window. If headphones / speakers are active, look for other items that contain “High Definition Audio” in the title or something similar. As soon as you find it, select the required component and click the “Default” button (or activate it through a similar item in the context menu):
