How to connect a computer screen to a TV. Description of various ways to connect a laptop (computer) to a TV: features of various methods with and without a cable

Do you want to increase your time spent on the computer? Perhaps you need to show a presentation but don't have a projector at hand? Why not connect your computer to a 50" HDTV. Or maybe you want to turn your laptop into a desktop computer, but don't have a monitor. Most modern computers can be easily connected to modern TVs.

Steps

Windows

Determine the type of cable you will use to connect your computer to your TV. To do this, look at back panel computer where the ports and connectors are located. Video connectors are located next to USB ports, audio jacks and Ethernet port, or they are located on a discrete video card (under the audio connectors). There are three main video connectors:

• HDMI. The modern standard for connecting HD devices, and most modern computers have an HDMI connector (on the rear panel). HDMI carries both picture and sound. The HDMI connector looks like an elongated USB port.
• DVI. Digital connector with contacts. It has the shape of a rectangle and three rows of eight contacts each. DVI only transmits images.
• VGA. Old standard. It has the shape of a trapezoid and three rows with 15 contacts. Do not use this connector if you have access to a DVI or HDMI connector, as the VGA connector provides poor picture quality. VGA only transmits images and cannot display images in HD quality.

1. Determine the types of connectors on your TV. Most TVs have jacks on the back, but some jacks may be on the side of the TV.

   • Most modern TVs have one or more HDMI connectors. This is the fastest and easy way connect the computer to the TV, and this connector provides best quality Images. HDMI cable is the only type of cable that carries both video and audio signals.
   • The DVI connector is not as common, but can still be found in many modern TVs.
   • VGA connectors are generally not found on HD TVs, but they are available on regular TVs.

2. Pay attention to the input signal label on your TV. This will help you properly configure your TV to display the signal from your computer.

   Buy the right cable. Don't be fooled by many companies that claim their cables are better than their competitors' cables. In the vast majority of cases, you won't even notice the difference between a cheap and expensive cable. A cable that costs a few hundred rubles will work the same as a cable that costs several thousand rubles.

   • If your computer and TV do not have the same connectors, you will need an adapter. For example, if your computer has a DVI connector and your TV has an HDMI connector, buy a DVI-to-HDMI adapter or cable. In this case, the audio signal will not be transmitted via HDMI, since the DVI standard does not support audio transmission.

3. Connect your computer to your TV using a cable. At HDMI connection You don't need any other cables for HDMI. When connecting via other connectors, you will need a separate audio cable to transmit sound.

   • To stream audio from your laptop, use a 3.5mm audio cable and connect it to the headphone jack of your laptop. On desktop computer Use the green headphone jack (on the back of the computer). When connecting an audio cable to your TV, use one 3.5mm audio plug or two RCA plugs.
   • If you are connecting via VGA, turn off your computer and TV first. In the case of DVI and HDMI, this is not necessary.

4. Switch the TV to receive a signal from the appropriate socket. To do this, use the “Source” or “Input” button on the remote control remote control. The connector you select must match the connector to which you connected the cable.

   Set up your computer to display the picture on your TV screen. This can be done in different ways depending on the type of computer you have.

   • Many laptops have a Display key that allows you to switch between connected displays. You may need to press the Fn key to activate the Display key; Moreover, this key may be indicated by an icon rather than the word "Display".
   • In Windows 7 (and later versions of Windows), press Windows+P to open the Project menu. In it, select the desired mode for displaying the picture on the TV screen (“Computer”, “Duplicate”, “Expand”, “Projector”).
   • At any Windows versions Right-click on the desktop and select Screen Resolution or Properties. In the “Multiple Displays” menu, select the desired mode for displaying the picture on the TV screen (“Computer”, “Duplicate”, “Expand”, “Projector”).

5. Adjust the display resolution (if necessary). The resolutions of your computer monitor and your TV may differ, resulting in blurred images on your TV screen. In the Screen Resolution or Properties window, use the Resolution slider to set the correct resolution and increase the clarity of the picture on your TV screen.

   • Most TVs have a resolution of 1920x1080. Select the resolution that has the word "recommended" next to it (if available).

Mac

1. Locate the video connector on your Mac. The type of video connector will determine the type of cable and/or adapter you can use. There are four main types of video connectors:

   • HDMI. This connector is similar to the USB connector, but it has protrusions on the sides. This connector is designated by the letters “HDMI”. If you have this connector, you won't need adapters. Most Mac computers and laptops released after 2012 have this connector.
   • Thunderbolt This connector is slightly smaller than the USB connector and is indicated by a lightning bolt icon. If you have this connector, you will need a Thunderbolt to HDMI adapter.
   • Mini DisplayPort. This connector is similar to the Thunderbolt connector and is indicated by a rectangle with a straight line icon.
   • Micro DVI. This is a narrow connector similar to a USB connector. It has the same icon as the Mini DisplayPort connector.

2. Locate the input jacks on your TV. They can be located on the back or side panel. The most common connectors are HDMI, DVI, VGA. If you connect HDMI to HDMI, you only need one cable (for video and audio signals). For other types of jacks you will need a separate audio cable.

   • Pay attention to the input signal label on your TV. This will help you properly configure your TV to display the signal from your computer.

3. Buy an adapter (if necessary). Once you know the types of connectors on your computer and TV, you can choose the right adapter.

   • If both your computer and TV have an HDMI connector, buy a standard HDMI cable.
   • If your TV has an HDMI connector and your computer has a Thunderbolt or Mini DisplayPort connector, you will need a Thunderbolt to Mini DisplayPort to HDMI adapter.

4. Buy a cable and decide on an adapter. When connecting HDMI to HDMI, buy any HDMI cable (a cheap cable will work just as well as an expensive one). When connecting via DVI or VGA, you need to purchase both a video cable and an audio cable.

   Connect the adapter to the video connector on your computer.

5. Use a video cable to connect the adapter to your TV. If both your computer and TV have an HDMI connector, use a standard HDMI cable.

   • If you're connecting via DVI or VGA, you'll need an audio cable to transfer audio from your computer to your TV. Use a 3.5mm audio cable to connect the headphone jack on your computer to the Audio In jack on your TV.

Computers have long replaced record players for many users. DVD discs and various musical equipment. Sometimes, the user wants to see a movie on big screen so that the sound also goes through it. IN this review We will look at several options for connecting a computer to a TV, both new LCD models and old CRT models.

HDMIcable

The highest image and sound quality can be provided by an HDMI cable. With the help of this additional equipment, not only personal computers and laptops are connected, but also tablets and smartphones. The gold-plated pins of the plug determine the high cost of HDMI, but only the original cable can meet the requirements modern user. Pay attention to your video card; if its model is outdated, then it simply does not have an input corresponding to the device.

Also, the output for this cable may simply not work, this cannot be ruled out, if this is the case, contact the LG service center technicians.

S-Video

This connection method is considered outdated and such an output is only available on older video adapters, that is, it is not suitable for everyone. There are two types of such cables, they differ in that one of them is equipped with an S-Video plug on both sides, and the second has a SCART for connecting to a TV. You will also need an additional cord for audio output; one of those described in the first example will do.

DVI

DVI provides digital connection and image transmission. There is only one thing: TVs are not equipped with similar connectors, but you can use a special adapter that will allow you to connect a VGA plug to the DVI socket, so it will cling to the TV.

How to TVLG connect your computer viaWi- Fi

You can connect your laptop to your TV using wireless internet connections, we will consider this option using the example of the LG Smart TV plasma panel. “Smart” technology will allow you to establish a connection with any device without using any wires or cables.

Smart Share, the program you need to of this type connection, the smart TV already has it, so all you have to do is download it to your computer. Download this software from the manufacturer’s website, this way you will avoid broken versions and possible virus applications.

TVLGhow to connect to a computer along with a monitor

The answer to this question is extremely simple, you will need two inputs on the video adapter, it is best if they are VGA and HDMI, the first will go to the monitor, and the second to the plasma, or any other TV. You can set up your PC for two monitors by right-clicking on the desktop and selecting “display settings”. After this, you will be taken to the monitor management menu, where you can make all the settings.

Adapter for CRT TV

It happens that there is simply no plasma panel or LCD monitor in the house, and the cord for connecting to old kinescope TV models simply does not exist, what should the user do in such a situation, how to connect old TV lg to computer? Most owners of such rare equipment believe that this procedure is impossible in principle, but this is far from the case.

In the picture above you can see a special adapter that will allow you to make a similar connection using an HDMI cable, standard double-sided tulips and a USB cable. Now I will briefly explain what the task of each of the component wires is.

USB in in this case acts as a charger, since the adapter itself must constantly receive voltage. HDMI will go from the computer, and from the splitter itself the tulips will go to the corresponding sockets on the TV.

Modern TVs can easily replace a computer display. But how does a computer connect to a TV?

We have collected various ways solutions to this common problem.

Connection selection

Attention will be given first optimal options regarding image quality, with which you can easily make a connection. After this, several additional methods will be given.

There is a possibility that the user will need to buy a cable from the store. Usually it is not very expensive, and you can purchase various devices at a specialized radio store or a retail chain that sells consumer electronics.

Please note that the presence of gold plating on expensive cables does not in any way affect the quality of the displayed image.

So, here are a few options for how to connect your computer to your TV:

• HDMI- an ideal option, because to work with it you just need to connect the connectors. As a result, not only sound, but also image will be transmitted well. The only possible problem is that sometimes it may not work from a laptop.
• VGA- one of the easiest ways to connect television. To do this, you only need a cable, which is sold complete with monitors. There is a possibility that the user has an unused device at home. If necessary, you can buy it at a specialty store.
• With cable from DVI the situation is the same - to work with it you only need to buy an adapter and cable.
• Alternatively, you can use a composite cable S-Video. You can work with it either through a cable or through an adapter. It’s just that he’s not considered the best way connections because the image may not be very clear. So such a connection is not used if modern technology is available. The connection occurs in the same way as when working with household players.

Connecting using HDMI

Surely many users have heard about this connector. It is on all modern TVs.

The HDMI cable has the same connectors on both ends.

You can buy a cheap cable. But if the user plans to work in 3D mode, it is better to use latest version HDMI cable.

A similar socket is located on the video card near the monitor connection.

If there is no discrete video card, the socket will be located on motherboard, that is, near the USB port. However, it will look similar.

With a laptop everything is much simpler - it has the same HDMI socket. But it’s located on different sides depending on the model the user is working with.

Sometimes the TV is hanging on the wall and it can be very difficult to insert the cables from the back. It is for this situation that a cable with plugs at right angles is sold.

Alternatively, buy a special HDMI corner.

Connecting a TV to a computer via a VGA connector

Video Graphics Array is an interface designed to receive and transmit analog video signals. There is no sound transmission in this option for connecting the TV to the computer.

Before connecting, make sure that both devices - the computer and the TV - are equipped with VGA connectors and have a special cable.

To make such a connection, your computer must be equipped with an operating system no lower than .

Connect the PC and TV with a VGA cable when turned off, then press the SOURCE button on the TV remote control (in some models this may be INPUT) and in the menu that appears on the screen, specify as an external signal VGA(in some models - PC or RGB).

After this, confirm the selected changes by clicking OK.

Additionally, you can choose to use multiple screens, which gives you the following options:

• Duplicate screens- a function that allows you to get the same image both on the monitor and on the TV screen;
• Expand screens- will allow you to simultaneously watch a video on the TV screen and, for example, type text on a computer;
• Show desktop 1 or 2 - this function operates only one of the available screens - either a monitor or a TV.

In general, the process of such connection is not difficult, however, it creates some inconveniences associated with the transmission of sound in this embodiment.

It will have to be connected with a separate cable or use an external speaker system for these purposes.

S-Video

Another option for connecting a TV to a computer is to connect using S-Video connectors.

This option is convenient because all televisions and computers (except very old ones) are equipped with an S-Video connector.

All you need to do is connect these devices with an “S-Video to S-Video” cable.

Before connecting, both the TV and the computer must be de-energized, after which you insert one end of the cable into the connector on the computer’s video card, which is a round black socket, and the other into the S-Video socket on the TV.

Then, on the TV, search for the signal source and adjust the image.

Miracast

Miracast technology differs from DLNA in that this option for outputting multimedia information from a TV to a PC simplifies the task of viewing not only recorded files stored on the gadget’s hard drive, but also played online on one of the built-in ones.

But Miracast technology has the only drawback - it is very demanding on computer resources.

So it is supported only by certain computers, as well as tablets and laptops that have powerful hardware.

It is important to implement such modern technologies on the TV itself.

If the TV only optionally supports Miracast, then you will have to spend extra money on an adapter that easily connects to the HDMI port.

The technology of a wireless monitor is very simple - the displayed image is compressed using a special algorithm.

After this, it is mirrored via Wi-Fi to a large TV display.

In this case, there is no need to connect the TV to one of the local networks using a router.

Thanks to the receivers, a separate mini-network is organized, simplifying communication with a PC.

To successfully transfer the image, install the Wireless Display add-on on your computer and start broadcasting.

Make sure that the Miracast function is activated in the TV menu. This can be done in the settings if you go to the tab "Networks" and go to the Intel WiDi sub-item.
