Installing hdmi on a TV. How to connect a laptop or computer to a TV via HDMI cable: step by step instructions and possible problems. This method is considered one of the simplest

If you need to connect a second monitor to a computer, but it is not available, then there is the option of using a laptop as a display for a PC. This process is carried out using only one cable and a little setup operating system... Let's take a closer look at this.

To complete this process, you will need a work computer with a monitor, HDMI cable, and a laptop. All settings will be done on the PC. The user only needs to perform a few simple steps:

Take an HDMI cable, with one side plug it into the corresponding connector on your laptop.
Connect the other side to an available HDMI port on your computer.
If one of the devices does not have the required connector, you can use a special converter from VGA, DVI or Display Port to HDMI. More details about them are written in our article at the link below.

Now you should start the laptop. If the image was not transferred automatically, click on Fn + F4(on some laptop models, the button for switching between monitors can be changed). If there is no picture, adjust the screens on the computer.

To do this, open "Start" and go to "Control Panel".

Select an option "Screen".

Go to section "Configuring display settings".

If the screen was not found, press the button "Find".

In the pop-up menu "Multiple screens" select item "Expand These Screens".

Now you can use your laptop as a second monitor for your computer.

Alternative connection option

Exists special programs allowing you to remotely control your computer. Using them, you can connect your laptop to your computer via the Internet without using additional cables. One of the most popular programs is. After installation, you only need to create an account and connect. Read more about this in our article at the link below.

In addition, on the Internet, there are many more programs for remote access... We suggest that you familiarize yourself with complete list representatives of this software in the articles on the links below.

To do this, inspect the connectors available on the device. If you cannot determine the types of ports by eye, find their description in the documentation for your computer. Depending on the device model, you can see the following types of connectors:

HDMI is a digital interface that is present on most modern computers... Transmits both audio and video, and therefore is optimal for outputting a multimedia signal to a TV.
DVI is another digital port widely available in the market. Transmits only video, no sound.
VGA is a popular analog connector. As with the previous port type, it outputs only video signal.

www.amazon.com

Mini DisplayPort, Thunderbolt 2, USB ‑ C, and Thunderbolt 3 (USB-C) are digital interfaces found in Apple computers... All of them transmit video and sound. In addition, the Mac can be equipped with a regular HDMI connector.

There are other types of connectors as well. But we have listed the most popular ones. Surely your device is equipped with one or more of them.

2. Determine which signal receiving connectors are on the TV

Examine the ports on the TV. Most modern models have HDMI and VGA connectors. Older ones are equipped with RCA ports, the plugs for which are called tulips:

3. Select the cable according to the available connectors

If you have an HDMI TV

If both the TV and the computer have an HDMI connector, then everything is elementary: you can connect devices using an HDMI cable. This option will be optimal.

To connect a computer that does not have an HDMI port to an HDMI TV, you will also need a special signal converter along with an HDMI cable. Which one exactly depends on the connector available on the computer. It can be DVI → HDMI, VGA → HDMI or other adapters to HDMI.

In addition to the HDMI cable, such converters can often connect an additional audio cable, the other end of which is inserted into a computer. This allows audio to be transmitted bypassing the limitations of DVI and VGA. An audio cable is often sold with a converter box.

www.amazon.com

To connect to a Mac HDMI TV with a Thunderbolt 2 or Mini DisplayPort connector, you will need a Mini DisplayPort → HDMI adapter along with the HDMI cable. For it to transmit sound, ask the store for such an adapter with audio support.

If you have a VGA TV

For a VGA TV, the procedure is similar. Only you need a converter HDMI → VGA, DVI → VGA or another, depending on the computer port. The main thing is that it converts the signal to VGA.

If you have an RCA TV

If you have absolutely old model TV with tulips, converters like HDMI → RCA, VGA → RCA and others, which give an RCA signal at the output, are suitable.

In order not to be mistaken when buying a cable or converter, you can tell the seller the types of connectors on your TV and computer: he will choose the right option for you or check the choice you made for compatibility.

4. Connect devices via cable

Turn off your computer and TV beforehand for safety. Next, connect the devices using a cable (and, if necessary, a converter). Only then turn on the devices. If the TV does not automatically detect the computer as a signal source, then do it yourself in the TV settings.

5. Adjust the picture on the TV using a computer

If the image is blurry, open system settings on the computer and find the section responsible for the monitor. Here you can set the resolution that matches your TV and, if necessary, change the video display mode.

How to connect a computer to a TV via Wi-Fi

Modern smart TVs can be connected to computers wirelessly via local area network Wi-Fi. Technologies like DLNA and Wi-Fi Direct let you stream video, music and other content to your TV screen, or completely duplicate the image from your computer on your TV, turning the latter into a wireless monitor. And in the case of Wi-Fi Direct, you don't even need a router for this.

For example, LG devices have a service for such functions. A Samsung TVs offer similar capabilities within the AllShare service.

Wireless settings may differ depending on the make and model of your TV. Some devices establish a connection in a semi-automatic mode. Others require additional software to be installed on the connected computer.

Therefore, formulate universal instruction that suits all users is difficult. If you want to connect your TV to a computer via Wi-Fi, you will find the necessary information in the paper manual or on the manufacturer's official website along with the software you need for this.

Innovative TVs Philips, Samsung, LG with flat screens, like a PC ( Personal Computer) are considered digital instruments.

Without exception, all processes occurring in them are, in fact, changes in continuously moving numerical streams. It may seem that to transfer to an ordinary digital TV, which will act as the same display, big number various information that is located inside the laptop is quite simple. In practice, however, this process is much more complicated.

How to connect a TV to a computer via HDMI will be discussed in this article.

How to connect

If earlier, in order to connect a CRT TV, RCA connectors were required, which provided an image output of the usual type, now we want to see images of the highest quality, but to ensure transmission of this quality we already need HDMI connectors.

The HDMI connector is located in the graphics card, it is designed to connect a laptop display, for example, Toshiba to an LG TV with cable support.

It can be noted that HDMI is more ideal than VGA. With its support, you are given the chance to broadcast a higher quality video in sync with sound. For this reason, it is more logical to use this connector directly when connecting a TV to a PC.

Order of operations

In order to connect a TV to a laptop, you need to do the following:

Disconnection. First, turn off both devices. To a non-working TV, simply connect a PC using the purchased wire. However, you first need to insert one end of the cord into the PC connector, and then the other end is inserted into the TV connector.
Customization. The first time you connect your laptop to the TV, you should definitely adjust the picture. To do this, you need to right-click on the desktop, then it all depends on your OS:
1. If Windows 7 is installed on your laptop or PC, then you need to select "Screen Resolution", then look for the "Screen" line and select the best option. If the connected TV was not immediately found by the laptop, then you need to immediately click "Find".
2. In Windows XP, you need to select "Properties", click "Options", then "Advanced", and then select the optimal value.
Your laptop's desktop will be reflected on the TV screen.
Note: if necessary, in the properties of the video card you will be able to carry out a complete debugging of the image quality.

If you often use the TV as a 2nd display, in this case, it is best for you to configure the options in it as on a PC. Follow the instructions for your graphics card. In it, you can adjust the "Clone" or "Mirror" modes, where both monitors are set up completely identical. In addition, it is possible to make one and the other monitors work independently, all using the "Extended Desktop" mode.

Why the PC does not detect the TV

In some cases, the computer does not see the TV even though everything has been done properly. In order to find out why there is no signal, you need to carry out diagnostics.

The reasons for the problem may be an old TV model or the fact that the laptop does not support the video format of the device.

Watch the video in which experienced user shows how to connect a laptop to a TV via HDMI cable:

When there is a need to connect some device to a TV via HDMI, then not many people ask the question "How to do it right?" What can this lead to? Let's figure it out.

Suppose you need to connect a computer or laptop to a TV via HDMI ports, most often people do this, take a cable and connect everything without any problems, hot.

The expression "hot" implies the connection of two electronic devices to each other without turning them off, i.e. at the moment when these devices are working. So, it happens that after such a connection, you can seriously disable your equipment. And in service centers have long disowned these breakdowns, as from what falls under warranty repair. So it is unlikely to work.

But how can this happen? After all, the HDMI developers have given the go-ahead for such a "Hot" connection. This can really be done safely if at least one of the connected devices is not included in the network, i.e. runs on battery power. If your laptop is plugged into an outlet, like the TV, then you risk connecting the cable to burn the HDMI ports or worse. This does not always happen, maybe everything is normal, but not everyone is always lucky, alas, there are such cases, but why?

If you don't go into details, then the fact is that there can be a rather high voltage potential on the buses of equipment connected to the network, you may have observed how, when a cable TV plug is connected to the antenna input of the TV, a spark can slip, the same can slip when connected HDMI. So, if certain conditions are met when connecting, rather large currents can pass through the circuits, which burn the ports.

Of course, if in your apartment the sockets are really with real grounding, and not just with a contact for visibility, then you have nothing to fear, but very many habitats cannot boast of high-quality grounding.

So what to do in order not to burn the equipment when connecting an HDMI connection

If you are not sure of the quality of the grounding of your wiring, then you need to follow simple order... A) If one of the connected devices operates on battery power and is not connected to the mains, then feel free to connect as is.

B) If both devices are powered from an outlet, then

1) Disconnect them from the network, and you need not just turn off the remote control into standby mode, this is not enough, namely, unplug or disable the surge protector button if used.

2) If the TV is connected to cable TV then it also needs to be disconnected.

3) We connect or disconnect the HDMI cable to the equipment, turn it on to the network.

By observing this simple procedure, you will save your technique from unwanted breakdowns.

P.S. If you have to make these connections often, then in order to avoid these switching-ons from the outlet, you can connect the equipment cases with a copper wire - ground them together.

HDMI cable, how to connect to your TV correctly.: 30 comments

I didn't even think that this way you can burn ports. I don't use HDMI very often, and I connected it directly. Now I realized that it was not right. And I was lucky that the port did not burn down. Thanks for the useful information. Now I'll know.

I struggled to burn one of the ports, the TV stopped turning on altogether. I thought of ordering a motherboard on the TV, so the power of the duty room should be 5 volts, but it was 2.9. After removing the controller and zener diode from the board, the TV worked, but now I have lost one port.
I bought a smart TV set-top box, but the signal is not transmitted from it to the TV, but from the ps3, what is the reason?
I tried to turn on the set-top box with a friend, it works for him, it doesn't work in my apartment on both TV sets, there seems to be grounding
I will tell you one case. I am a digital technician repair specialist. I came to a client's home one day to fix a TV set. The cause of the malfunction turned out to be an HDMI controller, which shorted out and did not even allow the TV to turn on. I soldered the microcircuit, went. and bought a new one. I arrived, soldered it, checked it - everything works, the HDMI signal goes through and gave a lecture to the owner about the prohibition of hot plugging. To which he vehemently objected to me, see, they say, the manufacturer permits. I answered him, I don’t care ... what the manufacturer allows there, probably this is a permit for people like you, who are ready to pay, a potential sucker to go and create a turnover. I warned him that the warranty repair does not cover damage that occurs during hot plugging. He objects to me again and says that he always connected that way and nothing, that I am an inexperienced master and do not understand anything, and decided to demonstrate to me that he was right. I had already put on my shoes at that moment and was going to go out. I have already received the calculation and issued a warranty card. No sooner had I left the door when I heard, look. I looked around and see that he successfully disconnected HDMI from the laptop, the picture naturally disappeared and the HDMI no signal lit up. Next is a lethal number. He says look here. I watch as he begins to casually crookedly connect the cord and welcome, the laptop and TV are fucking cut out and won't turn on anymore. The client got mad, began to vouch that I did it that way. I said that this was not a guarantee case and that he himself deliberately ignored the warning and left. He called the police, they then called me to the department, I told everything as it is. As a result, the case did not come to court. They managed with an independent examination, which confirmed to him the fact of his handshake and the rotten moral character of a narcissistic egoist. I think that such assholes should be. He considered himself the smartest, and in the end without a TV and an expensive laptop. Repairing it will not be cheap, and even after this sensational story, the rumor quickly spread, not without my help, and hardly anyone began to do it for standard, adequate money. The story means that you never need to listen to the seller. It is beneficial for him that your equipment breaks down more often and desirably hopelessly so that you come to buy again. The manufacturer is also a seller. A master, a real and experienced specialist, will always tell you what to do, and a lamer who wants to shake off more money from you for poor-quality repairs will not say anything, will ask a lot for repairs and, as a rule, is daring in communication and sets himself up as the smartest and most experienced craftsman. I want to correct the author of the topic a little. Grounding at outlets or between themselves will not solve the problem and will not reduce the likelihood of breakdown. The point is not only in statics, but also in connection signals, with incomplete and uneven or interrupted contact and in general contact with a hot one, large currents always slip, since no matter how you connect the connector, you cannot do it faster than the movement of electrons and will always the moment when the beginning of contact occurs, but it is not yet complete. The earth has nothing to do with it, although it will save from some factors, such as statics. Take care of your equipment. It is better to unplug it once more than to shell out thousands for your laziness.
- Thank you Sinister), for an example from life!
  I myself was engaged in repairs in the past and I confirm that there have been different clients and cases too.
  I also thank for the amendment, I must agree, the connection signals bring their own fly in the ointment.
  - This means that when you were doing the repairs, you were a good master, since you didn’t contradict it now, but logically agreed. Nedomaster, as I call lamers who consider themselves masters, would have objected to me in full, if only to bring in my own self))). Unfortunately, there are now the majority of such people, and this is very sad. They greatly disgrace our craft. Remember how it was before. There was only one master for the whole region, or even the city. He was expected and honored as a god. And they will feed and drink and give denyuzhku from the heart and spend it with a happy word. What now? Now there are non-masters who are pulling a lot of money from people during modular replacement, since at the component level they are complete zero, well, almost complete zero. Is that the bloated air conditioners know how to change. And after that "I AM A MASTER". Ugh, you learn to tie your shoelaces, I think to myself, then you’ll climb into the master. There are many of these imperfections, they are sowing YouTube with their videos, where they think they have done it correctly. A small part of them are masters. Mostly amateurs. In the backlight, the diodes change one instead of a two-watt one in skis, a single-watt one stuck. The woodpecker does not understand that the whole scheme has subsided from this and will not work for long. A couple or three minutes, or a little more if you're lucky. Customers are now all arrogant because of such steel. They call you not as a master, but as a slave, like you are obliged to do it. Not all, but a lot. Especially those who see enough different videos in youtube. Yes there they say what? just replace one detail, but to the question of what you can't do yourself, the answer is "ingenious" - there is no soldering iron.))) To the question, so it's cheaper, a soldering iron or repair of a master, the answer is silent. The matrix is removed without gloves, leaving their greasy imprints on the inside, especially when working with diagonals over 50 ″, they do not know that they can remove it carefully and without splashing or breaking the matrix only with suction cups without risk. Up to 50 ″ I carefully remove without gloves, but my fingers touch only the end of the matrix, which requires accuracy and smoothness so as not to burst.
    By the way, your article, but in general I was just looking for HDMI connection again for the stubborn client to read what others write. He was waiting for me on the recommendation of other people, but he also contradicted the correct connection, though he did not risk a hot connection.
    The topic I think about HDMI can also be supplemented by the fact that the versions of the cords themselves HDMI interface not small and each version of the cord can behave differently when hot plugged. It is not necessary that the entire HDMI chip will fly out. It can only be a specific port or even a port channel. Well, it's worth recalling that about half of TV models and probably all budget TVs do not have an HDMI controller. It is built right into the processor. And the breakdown in this case via the HDMI channel is much more serious and expensive, when it is sometimes cheaper and easier to find and buy a whole motherboard than to look for a processor, especially if the binding chips are tied to the processor with a software key. Philips, Samsung and Toshiba do not hesitate to do this in most of their models. Calculation for turnover.
    I wish you the author of the topic to print more useful topics. It can be useful to many. Our work will not be diminished by this.
Tell me so, I bought an apc pm8-rs surge protector, I connect the devices, the grounding lamp is on, there is no grounding in the apartment, or rather there is but for a couple of sockets, in the hall near the window and under the stove, but where the extension cord is there, not a single outlet is grounded , I connected it like this, ps4-pc-nintendo wii u-TV antenna cable TV-audio receiver-subwoofer-and the monitor as a second screen, which means that everything is connected via hdmi to the receiver and from it to the TV, I disconnect hdmi from the pc grounding disappears the light does not light up on apc pm8-rs I connect lights up, tell me how to solve this problem, or in order to solve it, you need to conduct grounding from the shield, and can it still affect that some kind of grounding is supposedly coming from the PC, well, I won't say so in this that when the refrigerator is running, and the split system, when they turn on, turn off, the image blinks and the sound disappears for a couple of seconds, and the audio receiver gives this blinking, this was not the case before when there was another audio receiver, tell me if I understood what to do, or to no avail aat, and these are bad spare parts in the new receiver, or somehow you can solve this problem so that there is no interference from the pc via hdmi.
Not the hdmi cables are normal, they changed different ones and the effect is the same, but that's why, I already wrote, but I'll also write why the image can blink, when you turn on / off the refrigerator and the split system, I read it from many people, people connected a laptop to the TV via hdmi , and the refrigerator gives a tip, with the power supply everything is normal 220, but the amperes, when turned on and off, they jumped with a device, I also read that people changed everything they could and put the grounding, etc. devices put shitty hdmi controllers, because I already wrote, with the old audio receiver everything was fine, but the new one gives such problems.

I'm all honestly confused about where to dig, if you buy a new audio receiver and there will be the same problem, before the crisis, even though there was confidence that such a device would not come across, for example, there is an lg TV, there is a back wall made of iron, and it is thin, but I bought a new TV, so they are all thick and plastic, those who made them thin and with an iron back wall are now making plastic ones, probably this is a conspiracy of manufacturers to do not qualitatively, in 2k18 and faster so that the buyer buys a new one.

Hello! I had a case when HDM completely flew on an LG TV, there were four ports, one wire was connected from the computer, all the time, and at some point HDM stopped working all four ports. Is there a difference, the sequence of turning on the computer and the TV?

Each of us at least once, but thinks about how to connect a TV to a computer and display the image on a large screen diagonal. This is done quite simply, but there are a lot of connection options, they all require different connectors, cables and other technical details.

Wired device connection is the most popular

The most popular way to connect devices is via an HDMI cable. Let's find out how to connect a TV to a computer via HDMI, consider what other connection methods you can try, especially through standard format VGA. In addition, we will dwell on how to adjust the screen image in order to make the broadcast as high quality as possible.

Connecting a laptop to a TV via HDMI has the following advantages:

This type of connection assumes digital rather than standard analog image (as with VGA) and, accordingly, has better quality.
The second advantage is that this type of output also transmits sound in addition to the image.

The process of connecting devices itself is quite simple: we take a cable with HDMI connectors, insert each end into the connector intended for it on the equipment.

Be careful! It is imperative to turn off the equipment before connecting, otherwise the ports may burn out, which will lead to their failure.

Note that the majority of modern laptop models are equipped by default with a similar connector - a regular format or in the form of a mini-HDMI. After connecting, turn on the TV and select another signal source so that it finds the image from the computer display.

Optional equipment

Sometimes there are difficulties with the connection via the HDMI connector. If the TV is placed in such a way that it is difficult to bring a cable to it, for example, a wall interferes with this, there are special corners. They are made in such a way that they create a bend, which makes it much easier to connect the cord, even if the appliance is snug against the wall.

It is worth noting another accessory that is useful for connecting via HDMI - a switcher. A similar device is used in televisions with a shortage of connectors. It occupies only one slot of the specified format, instead providing 3-4 connectors in its housing.

Image Adjustment

When you connected a laptop to a TV via HDMI, you often need to adjust the picture, which is now located on big screen... This is done through the context menu on the computer as follows:

Right-click on a free space on the desktop and select the "Screen Resolution" menu;
In the window that appears, you can change the resolution of the TV monitor - usually, the higher the indicator, the better and clearer the picture;
In the same menu in the "Multiple screens" list, you can edit their display - they can work in duplication mode, in which case everything that happens on the computer is displayed on the large display. If you select the Expand option, the TV will become an extension of the laptop display. You can also choose to display the desktop only on one of the monitors;
There is also a line "Make the main monitor", where you can specify exactly which display is considered the main one.

This is how the image is adjusted, and you can also edit the sound as follows:

In the bottom line of the laptop, right-click on the sound icon and open the Playback Devices menu;
A window will appear in front of you, which displays all the equipment to which the sound is output. Here you can mark the TV with the line "Use as default". Now all the sound will come directly from its speakers, you can change the volume with the remote control.

Other connection methods

If required connector on one of the devices is not, you can connect a laptop to a TV via VGA-HDMI. The VGA socket is present on all appliances by default, but it is now used much less often. Why? Due to the fact that the VGA format can only output an analog image, which is of inferior quality than digital. In addition, when connecting via VGA, you transfer only the picture to the screen, but not the sound - you need to take care of it separately.

Be that as it may, if HDMI is missing, you need to use what is. Connecting a laptop to a TV in this case is done like this:

Purchase the appropriate adapter;
Connect the laptop and TV connectors together - they can be left on.

As a last resort, you can always use a VGA-VGA connection, you only have to additionally output sound to a TV or play it through a laptop.

Connecting Apple Products

With the connection of products of this brand, the situation is a little different - they provide a connector called Mini DisplayPort. You can purchase a cable for it, at one end of which there will be a connector for this input, while the other can have both HDMI, DVI or VGA formats.

The connection is quite simple - you plug the cable into the appropriate jacks and select the signal source on the TV - nothing else is required.

Wireless connection

Separately, I would like to note that in some new laptops of leading brands, it is possible to connect to a TV wirelessly. This is done using the Intel function Wireless Display and the drivers that come with the hardware by default if you haven't reinstalled the system.

It should be noted that in this way the image is transmitted along with the signal. The only but - the second device must have the Smart TV function, or you will need to purchase a special stand.

But so far only advanced models have such functionality. It will not be superfluous to know how to connect a laptop to a TV via HDMI and VGA, other connectors, and correct the image. You can completely do it all yourself, thanks to which you can watch videos, photos or play on the big screen.
