We connect the TV to the computer through the HDMI cable: the instruction

An actual problem for many users today is the extension of the image from a personal computer to a home plasma display. "We connect the TV to the computer via HDMI, and there is no image," - that's how the negative sounds from the lips of the owners of computer equipment.

In this article, the reader will get acquainted not only with the method of connecting an additional display to a PC or laptop, but also learns about the correct settings of the equipment. He will also be interested in the recommendations of experts in the field of IT technologies.

About the objectives pursued

The larger the diagonal of the LCD screen, the more comfortable the multimedia viewing and the more detailed the image in the games and the operation of the software. The film on the TV from the computer will allow to see the smallest details, and the fan of the dynamic toy will feel the reality of the events on the plasma screen. In fact, the benefits of using such a symbiosis are many, and all of them relate to the comfortable work or leisure of the user.

In recent years, many users have been interested in Internet TV. Why pay money to the provider, if you can watch your favorite channels for free from the official website of the television company? Therefore, the question: "How to bring a computer to a TV?" Sounds more often in the media. But only with the ready decisions while things are bad.

The possibilities of computer equipment

To start better with the technical capabilities of a personal computer or laptop. The fact is that it is not enough to buy an HDMI cable for the computer. To the TV it will be possible to connect only if there is a corresponding digital video output on the PC. Therefore, the user needs to familiarize himself with all the outputs of the system unit and find the required port. It can be located on a video card or on the motherboard at the computer and on one of the ends of a mobile laptop.

There are devices that do not have an HDMI connector. It is quite possible to detect on the old PC analog video output VGA (D-Sub) or digital ports DVI with DisplayPort. Here everything depends more on the TV, in which there should be similar inputs. After selecting the desired cable for the TV, you will always find the ability to display the image from the computer.

TV availability

But modern liquid crystal devices with HDMI ports do not have any problems - all manufacturers provide their equipment with a demanded interface. Often, a single port in the factory is not limited and provides the user with the ability to connect multiple sources to output images via HDMI.

Large-format liquid crystal displays have a slightly different problem. It is about the resolution of the picture being reproduced and the frame rate. Before connecting the computer and the TV via HDMI, the user needs to familiarize himself with the technical characteristics of both devices, compare their video transmission capabilities and find a parameter that will be supported by both the plasma and the PC. Often, all equipment manufacturers are trying to ensure that the technology supports FullHD resolution (1920x1080) at a frequency of 60 Hz. However, there are exceptions, which create problems for users.

Work of devices of different generations

In situations involving the connection of two devices with different interfaces (HDMI, VGA), users are often surprised why the computer does not see the TV through HDMI. The explanation is simple - it is impossible to connect the technology of different generations, combining the analog and digital signal with one cable. In such situations, no adapter will solve the problem - you need a converter that can decode the signal at the hardware level.

Benefit at foreign auctions there are ready-made solutions that can solve all the problems of users with the transmission of video signals between devices of different generations. The cost of one converter is within 20-30 y. E., What attracts a potential buyer. All necessary cables for video transmission are always included in the package to the converter, so the algorithm for solving the problem is simple: we buy a converter and connect the TV to the computer via HDMI.

When there is no necessary interface

Not all computers and televisions have an HDMI port - it's a fact. But upsetting ahead of time is not necessary, since with obsolete devices the problem can always be solved. The fact is that the old equipment is oriented to the transmission of an analog signal. Let this technology is behind the image quality, however, with compatibility of different standards, it has an order of magnitude less problems. Combining S-Vidio, VGA or RCA interfaces is much easier than converting an analog signal to a digit.

The user just need to buy a cable for the TV and connect both devices. There are many inconveniences that users will have to face. Firstly, no sound can be transmitted over the interface cable. Accordingly, you need to buy another cable. Secondly, during operation, the sound card of a computer or laptop will not be able to create an individual audio stream for the TV. Accordingly, the convenience of sharing the computer and TV can be forgotten.

The right approach to buying a cable

Problems may appear with the user and when selecting the wrong HDMI cable. The fact is that the digital video signal is not able to be transmitted over long distances by cable without loss of quality. Therefore, the future owner needs to determine the length before buying an HDMI cable for the computer to the TV.

The main thing is always to remember that the longer the quality cable, the higher its cost. It is necessary to measure the distance between the PC and the liquid crystal display (naturally, not in direct line of sight, but with regard to stacking) and find on the market a length-appropriate cable. Yes, buyers tend to purchase wires with a margin, but it should be small, as often surpluses are rarely in demand - more often they simply collect dust behind a TV set or a computer. Here the main thing is to find the golden mean by the ratio of "cost - cable length".

Real offers from manufacturers

The cable for the HDMI-HDMI form factor TV is not easy to choose on the market. Any buyer can make sure of this on their own, just look at the prices and assortment. It is logical to assume that expensive accessories have a high price only because they are made by serious brands. This is true, but as practice shows, the more expensive an HDMI cable, the less likely it is that the video signal will deteriorate at a great distance. In fact, you need to pay for quality. Chinese consumer goods do not belong to the domestic market.

IT experts recommend paying attention to the brand name (for example, Prolink, Cablexpert, Viewcon, Belkin), and also to focus on the quality of the winding and the presence of ferrite filters near the connectors (kegs near the contacts). If you require an HDMI cable that is longer than 30 meters, the user without a signal amplifier can not do without. The device is expensive, but it cope 100% with the tasks set.

Physical connection of two devices

This article is not about the difference of potentials from the school physics course, but the user still needs to know that there is a small electrical charge on the video ports when the equipment is switched on. Naturally, when connecting two devices, a technician with a large charge will transmit energy via a cable to the port of the connected device. Often the TV turns out to be more powerful, which, when connected, burns the output on the video card of the computer. Therefore, before you connect the computer to the TV via HDMI, you must disconnect one of the devices (remove the plug from the outlet). Naturally, this problem is bypassed by all users who have a ground in the house.

Another trouble that a buyer may encounter is the lack of a video signal when a cable is connected or an image with interference is transmitted. No need to touch the settings of the TV or computer - 99% of the problem in a poor-quality cable. It is necessary to replace it. In general, experts recommend checking the HDMI cable directly in the store to avoid connection problems.

TV settings

It is not difficult for the owner of the liquid crystal display to press the "Source" button on the remote control of the device and select the desired signal source. All the ports on the TV's panel are registered and numbered, so it only remains to combine the software part with the hardware one. Do not expect that an image from the PC will immediately appear on the screen. The main thing here is to bring the display into readiness for receiving a video signal. This sets the connection of the TV to the computer via HDMI. It remains only to configure the video output of a PC or laptop.

Many users own home theaters, receivers, TV tuners and other video and audio equipment that is connected to an LCD TV. Naturally, there may be a situation where all the HDMI ports are busy. Many users hardly want to physically rearrange the HDMI cable when working with a computer, so another solution is suggested. The video signal from the laptop can be transferred to the tuner or receiver. In fact, there is no difference, as manufacturers use a single standard for image transmission over HDMI.

Modern platforms

When it comes to the operating systems of Windows 10 or MacOS, there are almost no questions with tuning. The user just needs to reboot the computer in order for the device to detect and connect a new display. The more modern the technique, the more efficient the automatic setting is - often on HDMI from the computer to the TV the signal is transmitted in the FullHD format with a frequency of 60-65 Hz.

But there are exceptions, and they are connected first of all with the video device driver. Therefore, you do not need to try to get the TV to operate properly from the remote control, only the fine adjustment of the video card will help . The main thing is always to remember that you need to change parameters not global, but only one port, otherwise by carelessness you can destroy the signal to the PC monitor, which will be difficult to restore.

Working with drivers

Making TV work, like a computer monitor, through HDMI, though difficult, but very real. To do this, there are many ways that the reader is to be introduced. Owners of the Windows operating system versions 7,8 and 10 need to go to the control panel and select the "Screen" item.

Switching to the "Setting screen parameters" tab, the user will find out that the operating system has already determined the connected TV, but the image does not yet transfer to it. The Multiple Displays option allows you to connect your TV as an additional monitor to your computer. There are several options in the list, from which the user is invited to make a choice:

1. Duplicate these screens. The contents of the computer desktop will be displayed on the TV screen, and all actions performed by the user will be visible on both displays.
2. Expand these screens. The most interesting setting that allows you to virtually increase the desktop area (both vertically and horizontally).
3. Show the desktop on the screen number. Manual assignment of the port for video output is not claimed by users.

Driver Customization Features

It's easy to send a signal to the TV, but it's not so easy to adjust the picture quality and transfer sound from the computer to the TV. First, you need to decide on the extension of the desktop - diagonally or vertically. Experts recommend to navigate the physical location of the TV in the room relative to the PC monitor. On the control panel, in the "Screen Resolution" menu, use the mouse to place the icon No. 2 relative to the icon No. 1 so that it is convenient to move the objects of the desktop between the displays.

The second step is to adjust the resolution of the TV screen. The main thing here is to choose a parameter that is supported by the connected display, otherwise it will fail, and the port for video output will be disconnected. By pressing the "Advanced Options" button, the user can select the refresh rate of the display, but IT experts do not recommend changing the frequency, unless the video card and TV support 4K (144 Hz). After making all the settings, you need to save the changes and exit the control panel.

Tricks with sound transmission

All users know that HDMI-cable not only transmits a high-quality image, but also a sound, but only the corresponding setting in the display resolution settings is missing. With the transfer of audio everything is simple - at the hardware level, sound comes to an additional screen along with the video. That is, the user simply drag the video player window onto the TV screen with the mouse. In the speakers of the computer, the sound will turn off, and will be activated in the TV speakers.

It is worth noting that a mobile device or a computer is capable of supporting several video devices connected via HDMI at a hardware level, transmitting a different image to them and providing them with a soundtrack. However, there are exceptions, and they depend on the video adapter and sound card. Low-capacity devices sometimes fail, they just do not have enough power to handle digital video and high-quality sound.

Alternate Driver Configuration

Not only means Windows you can configure the transfer of video on the TV screen. Owners of discrete graphics cards are given the opportunity to provide high-quality transmission through a video adapter driver (Nvidia or Radeon). The adjustment algorithm is the same: we connect the TV to the computer via HDMI and set the HDMI source from the remote control.

But further on, the firmware of the video card manufacturer is involved. If you switch to the control panel of the Nvidia Geforce Experience application or the AMD Catalyst Control Center, you should find the "Display" tab. One of the sub-items of this menu is responsible for setting up multiple displays.

Feedback from users

Often when connecting the TV to a computer or laptop, the owners of the devices have problems that they try to solve together in the media. The majority of the negative that occurs in the reviews is associated with a low-quality HDMI cable that was purchased at foreign auctions, or in stores at a low price. A greedy person pays twice - you need to know about this for all users who decided to save on buying an HDMI cable.

After setting the display settings and saving, the image on the main monitor disappears? This is the second problem that users often face. The reason is quite simple - the parameters of the main monitor have changed. Recommendation here is one - connecting the TV to the computer, you need to monitor their actions. Under the number 1 in the system is always the main monitor - its settings can not be changed. With the remaining numbers (2,3,4), you can do anything.

Finally

Yes, in order to create comfort, the user needs a little time and capital investments. Without this, simply can not do. There is an instruction in which all actions are prescribed, they must be clearly performed:

• Buy an HDMI cable;
• Connect the TV to the computer via HDMI;
• Configure the video adapter driver;
• Enjoy viewing.

The algorithm is simple, but there is a lot to be done. In fact, there is nothing complicated, most importantly, follow the recommendations of experts and perform strictly specified actions. Only having received an image from a computer or laptop on the TV screen and making sure that there is a sound transmission, you can go into additional parameters and make fine tuning.
