Which HDMI connector is best to connect your PC to? Connecting a TV to a computer via HDMI and more. Connecting the TV to the laptop with an HDMI cable
Some of the most common questions that users ask are questions related to connecting monitors and televisions to a computer. In this material we will look at one of these questions. Namely, the question is how to connect a TV to a computer via an HDMI interface.
The theoretical part of connecting a TV to a computer via HDMI
The HDMI interface is one of the most common interfaces for transmitting images from a computer to a monitor or TV. HDMI outputs are available on desktop computers, laptops, tablets, media players and other equipment. Moreover, almost any modern TV is equipped with at least one HDMI input. Such prevalence of this interface allows you to connect any monitor or TV to any video source.
In order to connect your TV to your computer via HDMI, you need the following equipment:
Most modern TVs have HDMI, so this isn't a problem.
Computer with HDMI output. If you connect a laptop, then it definitely has an HDMI output. If you are using a desktop computer, there may not be an HDMI output. In this case, you will need a DVI to HDMI adapter. If there is an HDMI output, then no adapters are needed.
You can purchase such an adapter at any home electronics store. The adapter is connected to the DVI output, after which you can plug an HDMI cable into it.
You will also need an HDMI cable. Like the adapter, an HDMI cable can be purchased at any store. When purchasing an HDMI cable, pay attention to its length, as these cables come in different lengths and longer cables cost significantly more.
The practical part of connecting a TV to a computer
So, we’ve sorted out the theory, it’s time to start practicing. The moment of connection itself is as simple as possible. All you need to do is plug the purchased HDMI cable into your TV and computer. If the computer does not have an HDMI output, then first connect the adapter to the DVI output, and then connect the HDMI cable to the adapter.
After you have connected the TV to your computer with an HDMI cable, you need to take the TV remote control and select the HDMI input as the signal source. As a rule, to do this you need to press the “Source” button on the remote control.
After clicking this button, a list of available signal sources will appear on the screen. In this list you need to find HDMI and select it. If, after selecting HDMI, your computer's desktop does not appear on the TV screen, then you have selected the wrong signal source. Click the Source button again and select a different HDMI input.
After the image from the computer appears on the TV screen, you need to right-click on the desktop and select “Resolution”. After this, a window will appear in front of you in which you can change the resolution and select the operating mode of your main monitor and the connected TV.
There are several operating modes available here:
Duplicate these screens - when using this mode, the same image will be displayed on the TV screen and the main computer monitor. In other words, the screens will duplicate each other. Extend these screens - a mode in which your connected TV will work as an additional monitor. In this case, you will be able to move windows from the main monitor to the TV. Display the desktop only on 1 - a mode in which only the first screen will work, that is, only the main monitor. Display the desktop only on 2 - a mode in which only the connected one will work TV and the main monitor will not receive a signal.
You can choose any of these modes depending on your need. After making all the settings, close the window by clicking on the “Ok” button to save the changes.
In this article you will learn how to connectHDMI to computer. First of all, you should determine what video adapter you have. If there is no HDMI output, a DVI channel with an adapter or DVI-HDMI connector is usually used. This channel is capable of transmitting sound of any quality.To set up HDMI, you need to understand the instructions that came with the TV. Next, you need to make sure that the sound signal is received by the TV. When you connect your TV and computer video card, you will need an HDMI to HDMI cable.
In order for the images on the TV screen and the computer display to be the same, you need to check the option for synchronous interaction of these devices. In this case, we will perform the following actions:
1) find Control Panel, first open Start
2) find the Screen icon and click on Screen Resolution Settings.
3) activate “Duplicate screen”.
If you want these two devices to function separately, then to do this you need to enable the “Expand screen” item. The monitor must be the main device.
The next step that needs to be done is adjusting the sound signal.
You need to do the following:
1) find Control Panel;
2) click on the equipment and sound icon;
3) click on control sound devices;
4) in the window that opens, open sound device management;
5) make it default. HDMI output;
6) click Apply.
To check the settings made and that the HDMI output is functioning as it should, open any video fragment.
We made sure that you should not, but perform all the settings yourself.
What cable is needed for HDMI output?
1) high resolution;2) with HDTV resolution.
There are cords from 1 to 10 m. The longer the cord, the higher the degree of sound signal loss. It is best to use active HDMI cables that are not afraid of distance. If you purchased such a cord, be careful and look at all its connectors.
In the case when Wi-Fi Direct is not configured, Miracast is not supported, there is no flash drive with a large capacity, but you really want to watch a movie in good quality, we remember the HDMI connector - a great way to duplicate an image on another device without losing quality. Therefore, the question arises: how to connect a TV to a computer via HDMI in Windows 10 and what is required for this? The answer is below.
What do you need to connect?
To connect we need:
- laptop or desktop PC with HDMI output;
- TV with HDMI input;
- reversible HDMI cable.
Attention! To get a high-quality picture with an audio track, do not use adapters from HDMI to DVI and VGA, otherwise watching movies and photos will only leave negative emotions.
How to connect a computer to a TV
So, to transfer the image to TV we need to connect two devices using a cable:
Chances are you won't see your laptop screen projected onto your TV.
To do this, TV and PC need to be configured:
But if this does not happen, the external signal transmission is disabled on the laptop or PC.
To enable it you need:
The best way is the “Second Screen Only” option, in which the image from your machine will be accurately copied onto the TV screen, while the computer display itself will remain turned off. Selecting a different connection will result in two monitors running at the same time, which has a distracting effect.
If your panel has a high resolution display, the transmitted image may be blurry or grainy.
To fully utilize the resources of your TV screen, you need:
Advice! If you don’t have cable television, and IPTV is hard on your wallet, you can watch TV through your computer: turn on the online broadcast or subcast on your PC and broadcast the image on TV.
“What progress has come…” I want to sing, looking at the shelves of modern supermarkets with digital equipment. The age of new technologies is constantly changing everyday life, and today you can watch your favorite movie not with a nasal pirated translation, but in high quality HD or Blu-Ray. All you need is HDMI outputs on your TV and computer.
The first thing you will need is an HDMI cable. Often it comes bundled with the TV. If not, you can buy a cable at any audio-visual equipment store. Decide in advance what length of cable you need. The latest generations of TVs have several HDMI connectors on the back. Connect one end of the cable to HDMI 2 and the other to the HDMI port of your computer or laptop. Don't worry if, instead of the desired image, you see a warning on the TV screen that the cable has not been connected or there is no signal. How to proceed in this case is shown using the example of Samsung TVs. Find the Source button on your TV remote and select HDMI 2 from the list provided. Perhaps at this stage the issue will be resolved and the image will appear on the TV screen. If nothing has changed, go to the computer (laptop) settings - right-click on a free field of the desktop. A window will appear in which you need to select “Screen Resolution”. Pay attention to the line “Multiple screens”. If it is set to “Display desktop on 1 (2) monitor only”, change it to “Duplicate these screens”. In the “Screen” item, the inscription “Multiple monitors” should appear.
Before connecting your TV to your computer via HDMI, it is important to buy a high-quality cable that matches the interface of both systems, and also learn about the software settings. Most modern TVs are equipped with this connector, and it is also present in many PCs. Laptops starting from 2010-2011 are almost always equipped with the necessary port.
Using an HDMI connection has several advantages: excellent Full HD resolution at 60Hz without the need for heavy setup, and excellent sound quality. You can also connect a TV for games - a large screen is perfect for this, inferior in response and picture quality to good monitors.
Preparing to connect
The first step in preparing for connection is purchasing a good cable. The quality of sound and picture will depend on it. Sometimes a mediocre HDMI cable can lead to a loss of brightness of up to 50%, so you should not skimp on its choice.
It must be remembered that the HDMI protocol is updated and improved every year. This means that the new version is better than the old one in 90% of cases. During production, backward compatibility technology is used - all the functions of the old accessory are retained, but new models add improved capabilities.
Important! Each HDMI cable has its own protocol number. The most popular versions are 1.4 and 2.0. The second option is considered optimal.
There are also additional methods for classifying cables:
- Deep Color– a wire with this mark will give a maximum of displayed colors; it is best used to connect high-quality TVs, which cover at least 1 trillion shades.
- Standard– a classic cable for working with a resolution of 1080 pixels, suitable for use at a distance of up to 15 meters.
- V.Color– Designed for the latest high-definition TV models.
- High Speed– This wire is designed for 1080 resolution, but uses a 7.5m length, improving the monitor's response time.
After selecting the cord, you need to find the HDMI jacks on your computer and TV.
Finding a port on devices
In most cases, the HDMI port is labeled on the PC board, on the side wall of the laptop, and on the TV itself. Outwardly, it is similar to the usual USB, but has beveled corners, like a trapezoid. Nearby there are pressed or raised HDMI letters.
The ports are identical for all devices, so the cord will have the same ends. If you need to connect your TV to a computer with integrated graphics, the port will be located in the area of the connector on the external bracket of the motherboard. It's usually right next to the USB.
Important! If the TV is mounted to the wall, then a regular wire will not work. You should choose an adapter in the form of an angle that connects to the TV panel, and then a standard cord is inserted into it.
It happens that you need to connect several PCs (2-3) to one TV. In this case, you can use a switch - a device that redirects the signal to several ports.
TV as a second monitor for a PC
Most PCs and laptops have 1 HDMI input, but this does not limit the number of connected monitors. A regular screen can be connected with other cables - VGA or DP, but these methods provide a slightly different quality. In any case, the TV can be connected to the PC as a 2nd monitor via HDMI.
Select HDMI input as signal source in TV settings
When you connect the TV to a laptop or computer, most often there is no image, or a blue screen appears and a “No Signal” sign appears. This indicates that the factory settings do not automatically change the signal source.
In this case, you need to determine the port through which the TV receives the signal:
- take the remote control for the equipment;
- find the Input or Sources button;
- click and select the signal source in the menu that opens.
Most TVs allow you to select the active signal source in this menu. Otherwise, you will need to indicate the numbers - sometimes they are written on the panel under the port, but more often you need to look at the instructions.
If everything is done correctly, the screen will display a picture that works on a laptop or PC monitor. Next you need to make fine adjustments to the image.
Setting up an HDMI-connected TV in Windows
Correctly setting up your TV when connected to a PC is the key to pleasant work, games and watching movies. Only competent determination of resolution and color calibration will help you enjoy the process. The current operating system is Windows 10, but its configuration is not much different from version 8 and is very similar to manipulations with the “seven”.
After the signal has been established on the TV, we begin to determine the parameters on the PC:
- You need to press Win+P on your keyboard (all letters are shown in the English layout). A side panel will appear on the monitor, through which you can control the operating mode of the monitors.
- Most often, you need to set the video transmission mode to one of the selected displays. The “Recurring” option is required to solve professional problems. The “Computer screen only” mode will automatically turn off the external display, this is important when using a laptop.
- The features of the "Expand" mode are suitable for working with some applications. For example, when you open Photoshop, the finished image will be displayed on the second screen without toolbars.
- Next, you should set comfortable screen mode settings. To do this, right-click on a free area of the desktop and the “Display Settings” item will appear.
- When setting up version 7 or 8 of the system, the name of the item changes to “Screen Resolution”, allowing direct access to the required parameters.
- Numbers are displayed in the corners of the screens, where 1 is the main monitor and 2 is the auxiliary monitor. TVs almost always serve as an additional display. If you check the “Set as primary” checkbox under it, they will switch roles with the PC monitor.
- The remaining settings are less interesting. The orientation, for example, changes only when connecting monitors placed in a vertical position. This is convenient for reading large articles or programming.
In the “Advanced screen settings” item you can find resolution settings. You can experiment with them, choosing a smaller or larger value. Whatever is more comfortable for the eyes and the tasks being performed, that’s what you put in.
When setting the resolution, you need to take into account the parameters of the GPU or discrete video card. For example, if you have a separate modern-generation video card, you can set the maximum resolution, play games and watch movies. If the graphics processor is built-in or “ancient”, it is better to choose in the ratio of performance/system care. Overheating and wear and tear will lead to rapid breakdown of a weak discrete card and can damage the built-in chipset.
What to do if the sound from the computer does not go to the TV?
It happens that after all the manipulations and in the absence of external speakers, the TV does not reproduce sound. In this case, the settings must be made in Windows:
- Click on the system tray (lower right corner with the time line).
- From the menu that appears, select the speaker icon and click Playback Devices.
- Select the TV displayed in the list as the default playback device.
- Click "Configure" to make sure it works.
A “Test” button will appear in the menu that appears; by clicking on it, you will hear the sound of bells that will test the left and right speakers of the TV.
Connecting a 4k TV to a computer. Ultra HD over HDMI
You can connect a 4K TV to a computer only if you have a modern video card that supports this resolution. In this case, the image will be clear and beautiful. If you connect a less powerful card, the performance will drop and there will also be a risk of overheating the PC system.
Important! When displaying a screen at 4k resolution, the frame refresh rate will be 30 Hz, whereas a minimum of 60 Hz is required.
The situation can be corrected only if the video card has an HDMI 2.0 standard, no lower. The cable should be similar. If you connect to other standards, the colors will be incorrect.
If you are satisfied with the 1080 pixel image, you can disable the Ultra HD option in the TV settings. If you need to maintain 4k, then do things differently. To do this, in the display properties through Windows, select the maximum resolution - 3840x2160.
Using a TV like this for games is a dangerous task if the card is not the latest generation, and the screen refresh rate may seem too low.
Connecting a TV to a laptop or PC using HDMI is a simple and easy task. The main thing is to choose the right cable, set a convenient resolution and use any standard TV with this port and 1080 resolution, then no problems will arise.
