How To connect the system unit to the TV

From a PC, the picture can be displayed not only on the monitor, but also on the TV. Why do this and how to organize the connection, the article tells. It contains a description of the most common options for the interaction of the system unit with a TV, as well as instructions that will help you set up the image and sound output.

 

Why you need to connect the system unit to the TV

By connecting a computer to a TV, you can turn a classic TV into an analog of a smart device . But why do this? This makes sense when, for example, a computer monitor is out of order. In addition, the TV display can serve as an additional monitor, which is also convenient. And it is many times more practical to buy a TV set if you do not have a TV set or a monitor yet.

Plus, on the big screen, almost any picture, photo and video materials look much more impressive. A solid TV allows you to get a much more vivid experience of watching movies or gameplay.

 

Most modern and not so modern TVs can be turned into a primary or additional PC monitor. Depending on what connectors are on both devices ( system unit and TV), you just need to choose the optimal connection method. Fortunately, a variety of options will allow you to cope with the task without much difficulty. How this can be done is discussed in the next section.

How to connect a system unit to a TV

Typically, system units and TVs are equipped with multiple inputs for connection. You need to find a connector that will be built into both devices. Below are six common options.

DVI

There are three main types of this connector. Their features are described in the table below.

View Decoding Peculiarities
DVI-D ( dual link type (M / M) DIGITUS) D – Digital, digital Used for direct digital connection between video source (video card) and TV. Connecting with such a cable provides fast information transfer, better image quality in comparison with analog cables.
DVI-A A – Analog, analog Converts a digital signal to analog, which is why its quality is lost.
DVI-I I – Integrated, combined A universal option. It has the ability to transmit both analog and digital signals.

 

HDMI

This is an international connection standard. Connecting with such a cable (for example, manufactured by 2E ) provides excellent signal quality (both video and audio). If, besides other ports, there is this one, it is better to choose it.

The HDMI connector can often be seen in both television devices and computers. To connect the system unit to the TV, you just need to connect the devices directly through the appropriate cable.

 

A couple of points to consider:

  • If the ports are the same, you will need a regular patch cable.
  • Sometimes one of the devices can be equipped with a miniHDMI input (a reduced version of the standard). Is there anything you can do? Of course yes. You just need a miniHDMI-HDMI cable, for example, 2E (AM / miniAM).

VGA

Transmits an analog type of signal. It is found in almost all video cards, including integrated video chips.
Before connecting the system unit to a TV via VGA, for example, Digitus VGA (HDDB15M / M) , you need to find out what resolutions the TV supports. As a rule, such data is available on the manufacturer’s website, as well as indicated in the technical documentation.

 

By choosing this method, the user must be prepared for the fact that regardless of the maximum resolution that the PC video card provides, TVs in this case can only broadcast a picture in a fairly low resolution. These are connection features and there is no way to fix the situation.

Network cable

You can also connect devices via the Ethernet connector, but there are some nuances here. So, a direct connection without using additional devices may not work if a username, password or server address is required to connect to the Internet.

 

You can solve this problem using a router . The provider’s cable is inserted into the network device, and then the TV is connected to it. The method works with any type of Internet connection. Below is a step-by-step discussion of how to connect the system to a TV using an Ethernet cable, such as Digitus AWG 26/7:

  • Connect the TV to the router with a network cable through the LAN port and install a media server on it. To do this, you need to download and install software for broadcasting data from a computer.
  • After installing the program in the settings menu, you must specify the device “TV”, mark the items that need to be displayed on the TV.
  • Run the program.
  • Turn on the TV, select “Source” in the parameters, after which a utility will appear in the list that will allow you to watch the files stored on the system unit.

Miracast

Miracast (MiraScreen) is a development, thanks to which you can easily project a picture from the display of one device to another, and you can do this not only from a laptop , desktop, but also from mobile gadgets .

 

You can understand whether a device is compatible with such a wireless connection by looking at the manufacturer’s website. It can also be contained in technical documentation. It is possible to determine whether devices support this type of connection by simply examining the settings in the device menu. Typically, this data is displayed in the item “wireless screen” (wireless connections) or other menu items that relate to functions related to the Internet or Wi-Fi.

Note : devices with Windows OS version 8 and higher are compatible with this technology. If the device does not have Miracast support, then you can solve this problem by purchasing a separate compact gadget known as the Miracast receiver.

S-Video

This analog output is built into most video cards. And TVs often have multifunctional SCART ports. Using the appropriate cable or adapter, you can connect the system unit to a TV device.

Note : in terms of quality, this method is superior to the connection via VGA.

 

So, with the connection options, connectors and cables , the disadvantages and advantages of each of them, everything is more or less clear. But there is one more nuance that should be considered. Finding the right cable and connecting the devices is only 50% of success. It is also important to correctly configure the devices so that a picture is displayed from the system unit to the TV display.

Configuring Image Output from a Windows 7 PC
Where What to do
Call the context menu Go to “Screen Resolution”
A window will open In the upper corner, click “find”. This will activate the search for the connected device.
Column “Multiple screens” Choose a suitable display option:
“Duplicate Screens” – both TV and monitor will work, transmitting an identical picture.
If you click “Expand screens”, then the PC monitor and TV will be recognized by the system as one. Part of what is happening will be visible on the monitor and another part on the TV.
If you click “Show desktop only 1 (2)” – the image is displayed only on the screen selected by the user.

After completing all actions, it is necessary to confirm each of them by pressing the corresponding key.

 

In other versions of the operating system, the process for setting up a connection is almost identical. Differences can only be in the names of the items, but they are not significant: you can intuitively understand which of them is responsible for what.
In the case of using the software when connected via a router or network cable, there may be individual settings. It all depends on the software and the connection method. However, everything can be figured out, again, intuitively: the interface of such utilities is quite simple.

Sound from the computer does not go to the TV: reasons

If in the audio parameters of the PC the TV is not assigned as a device that will output sound, then the audio will not be played. This is the main reason. The situation can be corrected in just 4 steps. The following table will show you how to do this.

Stage Action
1 Right-click on the sound icon in the notification bar and select “Playback Devices”.
2 After that, a window will open in which the playback devices, “Speakers” will be displayed, and the name of the TV will be displayed, for example, SONY 100ZD93 (KD100ZD9BR3).
You need to click on the TV device with the right mouse button.
3 Select “Use as default”.
4 Click Ok to save the changes. Then the sound is reproduced by the TV speakers.

 

It is also important to know that DVI and VGA are only capable of transmitting video. In order for the sound to be reproduced, you also need an audio cable with mini-jack connectors at both ends. This standard is almost universal and there will be no problems with the purchase of such a cable. Or you can not bother and just connect any acoustics to the system speaker .
