How to connect a laptop to a TV via hdmi

Before an overwhelming number of users, sooner or later, the task arises of how to transfer an image from a monitor screen to a television display. In most cases, this is due to the need for more comfortable watching movies or TV shows, however, this is not always due to the desire for entertainment. Connecting a large screen can facilitate the work of many specialists, ranging from people working in the engineering field, to people of art who simply need a large screen to more clearly work out their work. In addition to size, the TV has other advantages over the computer screen. You can use a netbook, but it is most convenient to connect to a laptop.

One of the most important is picture quality and color reproduction. These factors invariably affect the perception of images from a large screen. For many inexperienced users, translating a laptop image onto a TV screen seems like an incredibly difficult task. This article serves to debunk the myth of the difficulty of pairing two devices through a regular cable. In this case, we will consider a way to connect two devices via an HDMI cable. Before. How to start the configuration and debugging should say a few words about what can come in handy in switching two devices.

What you need to connect

Before connecting, make sure that you have a suitable connector on the switched devices. And also, that they work, to figure out how to connect them. If on one of the devices, whether it is a laptop or a TV, a suitable input or output is not found, you should use a special adapter or adapter.

After the user is convinced of the presence of two connectors of the same format, you should select the appropriate cable. For two identical ports, the cable must have the same connectors.

HDMI functionality

Before connecting, a few words should be said about HDMI technology itself. This method of image transmission is used everywhere. This is due to the fact that HDMI provides the highest quality image transmission without distortion and interference. Also, what distinguishes this connector from the same VGA, HDMI is capable of transmitting not only video but also audio information, which allows the user not to worry about additional connectors or adapters.

Audio and video information pass through one cable of the HDMI format without distortion and interference, which makes this connector the most comfortable and suitable to use. Among other things, one of the main advantages is that this port is on almost all devices, which allows you to do without unnecessary converters and adapters.

Today, there are two variations of the connectors: version 1.0 and version 2.1. Their difference is in the quality of signal transmission and support for multiple audio channels. You can buy such a cable in any special store for a very affordable price. However, in many models of TVs, this cable is included, which avoids unnecessary expenses.

The first point will be the connection of a laptop and a TV with one cable. To do this, just connect one end of the cable to the appropriate port on the computer, and the other end to the same connector on the TV device.

Reference! It is almost impossible to make a mistake in the connection, since most ports, both on TV and on the computer, have unique sizes and shapes, so finding similar connectors will not be difficult even for those who are not familiar with the technique.

Typically, on a TV, the desired connector is on the back of the device, sometimes on the side. On a laptop, the port may be in any place, depending on the model and manufacturer.

After the connection is completed, you should begin to configure the software part of these devices. First, set up the image on the TV. Using the remote control from the TV, go to the menu of signal sources. There are two ways to do this. The first way is to find a suitable subitem in the general TV menu. Second, press the Source (Input) button on the remote itself. After the user has opened the "Signal Sources" section (the name may differ in different models), he should choose the port from which the image will be transmitted to the screen. In this case, it is an HDMI connector.

Reference! In most modern models, inactive ports cannot be allocated. This reduces the probability of error to zero.

If everything is done correctly, after selecting the necessary connector, the laptop desktop should appear on the TV screen.

After setting up the TV, you should start setting up your computer. To do this, select the screen settings menu. There are several ways to do this. The first and most obvious way is to right-click in the free space on the desktop and select the "Screen resolution" sub-item in the menu that appears. You can also open the Start menu - Control Panel - Screen. And the easiest way is to use the Win + P keyboard shortcut, which immediately opens the necessary settings.

After the user has entered the screen settings menu, select the resolution that will be used on the TV display. It is recommended to take the maximum, since with a different size, the image may be distorted, stretched or narrowed.

Also in the Windows OS, several modes of interaction with an additional screen (in our case, a TV) are available for the user. The easiest way would be to use a TV display to relay the image. In other words, the screen on the TV will duplicate all the images from the computer monitor. It is also possible to turn off one of the screens and transfer the image to only one of the connected devices. And the last mode is to expand the desktop. This mode prompts the user to supplement the laptop monitor with a TV screen, which provides greater multitasking.

Reference! For clarity, the modes in Windows 8 and 10 are accompanied by demonstrating illustrations that explain the basic functions.

After connecting the image, you should start connecting the sound. Often, a TV device has a better audio system than a computer, which is why playing sound through the TV speaker is a more appropriate step than through laptop speakers. In order to adjust the sound, on the laptop should go to the settings menu. There are several ways to do this. The easiest way is to right-click on the speaker image in the notification panel. Then select the sub-item "Playback devices". You can also find the necessary menu through "Start" - "Control Panel" - "Sound".

In the menu that appears, a list of connected devices that are capable of playing audio will appear. Having found the necessary device, you should call the context menu. By right-clicking and selecting the "Use by default" sub-item, after which the sound should be reproduced using the speaker system of the TV device.

Reference! Many TVs, in addition to image quality settings, have sound settings. In modern models, in addition to the standard equalizer, there are such features as additional amplification, which can increase the comfort of using a TV device.

The best way out of the situation is to replace it with a new one. However, if it is not possible to replace the defective part, you can fix the breakdown yourself. If the user has the necessary tools and skills, you can find a gap in the cable and repair the damage yourself by soldering. Often the contacts are broken at the junction of the cores with the connector.

Also, during prolonged use, damage to your own connector on the TV or computer is possible. In this case, an experienced user can disassemble the device’s panel and repair the damage by itself using a soldering device. If the user does not have a tool or does not have special knowledge and skills, then the only solution to this problem will be a trip to a specialized service center.
