How you can use the monitor from a computer

When you can’t, but really want to: two different monitors from one DVI port

Before everyone used to sit at a computer with one main monitor, then there were laptops with low-quality matrix, since then began to connect a second monitor. Personal computers appear in the apartments more and more rarely, giving preference to laptops.

And it’s true, the notebook does not take up space, you can take it with you on the couch, it has enough power for most tasks, and it consumes much less electricity. And if you want to use your laptop as a desktop computer, you only need to connect an external keyboard, mouse, and monitor, t.ч. Two screens are now the norm rather than something weird.

Want to increase the amount of time you spend at your computer? You may need to show a presentation and you do not have a projector handy? Why not connect your computer to a 50″ high definition (HD) television. Or maybe you want to turn your laptop into a desktop and don’t have a monitor. Most modern computers can be easily connected to modern televisions.

  • HDMI. A modern standard for connecting HD devices, and most modern computers have an HDMI connector (on the back). HDMI transmits both picture and sound. The HDMI connector looks like an elongated USB port.
  • DVI. Digital connector with pins. Rectangular in shape with three rows of eight pins each. DVI only sends pictures.
  • VGA. Older standard. Has a trapezoid shape and three rows with 15 pins. Do not use this connector if you have access to a DVI or HDMI connector, as the VGA connector provides poor image quality. VGA sends only an image and can not display a picture in HD quality.
  • Most modern televisions have one or more HDMI connectors. It is the fastest and easiest way to connect your computer to your TV, and this connector provides the best picture quality. An HDMI cable is the only type of cable that carries both video and audio.
  • DVI connector is not as common, but you can still find it in many modern televisions.
  • VGA connectors aren’t usually found on HDTVs, but they are on regular TVs.

Take note of the labeling on your TV’s input. This will help you correctly set up your TV to display the signal from your computer.

  • 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, there will be no audio transmission via HDMI, since the DVI standard does not support audio transmission.
monitor, computer
  • Use a 3.5mm audio cable to send sound from your laptop and plug it into the headphone jack on your laptop. On a desktop computer, use the green headphone jack (on the back of the computer). Use one 3.5mm audio plug or two RCA plugs when connecting the audio cable to the TV.
  • If you connect via VGA, you must first turn off your computer and TV. In the case of DVI and HDMI this does not need to be done.

Switch your television to receive the signal from the appropriate jack. Use the “Source” or “Input” button on your remote to do this. The connector you choose must match the connector you plugged the cable into.

Instead of a conclusion

Everything is clear as to how you can use the monitor as a TV. The same goes for the question of using the TV as a display. But is there really no compromise to avoid the need for adapters, receivers, working with a soldering iron and other difficulties? Yes, but it requires an investment. You just need to buy a universal device that combines TV and display functions for PC. You can use a computer monitor and television “in one person”. Any TV with T2 and HDMI support, with a diagonal of 20-30 will do? (more is a bit much, as for a universal display) and a resolution of 1920×1080 dots. If you use a monitor together with PC which is not one year old already, but TV is absent at all or it is old and does not support DVB-T2 broadcasting, such decision will not be a senseless waste of money. After all, if you need both, but don’t have room for two devices in your room, sooner or later both devices will need to be replaced by one.

There are two options for watching shows on your monitor: Watching streaming Internet video; Watching digital terrestrial television. For the first case, you need a set-top box with the Android operating system. than enough equipment on the market.Also, the set-top box can be ordered in China. Connection is via HDMI or RCA (Tulip). To connect via RCA you need a converter or HDMI-RCA cable. With this set-top box you can watch streaming video via the Internet, as well as digital broadcasting standard DVB-T2. You can also buy a set-top box just for watching streaming video, it will be cheaper, but not significantly. For the second option is suitable set-top box standard DVB-T2. To watch TV channels on the monitor you just need to connect it. Connection is similar to the previous one. Typically, these set-top boxes also have HDMI and RCA (cinch) interfaces. You can connect a set-top box for watching TV to almost any monitor (remember that the monitor must have built-in speakers). If the TV and STB connection interests are different, then you can always find an adapter or converter which suits the specific situation. Using the monitor as a TV set does not always make sense, because the converter may cost more than the monitor itself, but if you have a second modern monitor, which you do not use, you can use it as a TV set. The main problem of viewing TV on the monitor, though, is the presence of built-in speakers in the monitor. In fact, there are very few such models. But if you own such monitor you can use this instruction for watching TV programs on your monitor. 3.5 / 5 ( 86 votes )

What is in a computer monitor?

The modern monitor consists of a screen (display), power supply unit, control unit and housing. The information for displaying on the monitor comes from the electronic device that forms the video signal (in a computer. the video card or the graphics core of the processor).

There’s absolutely no air inside it. The tube’s neck is not only long, but also quite narrow. The other part of it is called the screen, and it has a wide shape. The glass tube at the front is coated with phosphor (a mixture of rare metals).

A little bit about the monitor

Since my parents do not like to throw away equipment, the monitor Samsung SyncMaster (CRT monitor), after buying a LCD monitor, was carefully carried away for safekeeping in the shed in the country house and there safely forgotten. Once again, cleaning up the “stuff” my father came across the monitor and wondered if it was possible to watch the news in the country. But he could only get the answer from his advanced son, that is me, which he did by calling me one evening.

Since the monitor, in simplified terms, is a kinescope with a scanning unit without a radio, which is in a TV set, and without sound system. In other words, it is a TV, but simplified and deprived of some parts. In essence, the monitor only has a power supply, a sweep unit, and a video eliminator. The only source of the signal is a VGA(D’SUB) connector, which is fed with an analog signal. And this means that? And this means we need to find a device which will be source of signal.

If you have a newer monitor, it’s probably even easier because some monitors, if we’re talking about LCD, are equipped with speakers, and the newer ones have an HDMI input. If you have one of these, then you have a very wide range of options how to turn the monitor into a TV.

Two ways to turn the monitor into a TV. Bidyukov Denis

I’m sure many of you have bought a new monitor and wondered what can be done with the old one. This idea occurred to me, and I really thought about it a long time ago, but then there was not such a wide choice of different devices. But Chinese brothers do not sleep and invent devices with unprecedented combination of features. One of such devices is a TV set top box I bought to add features to the old TV.

But after connecting the set-top box to the TV, I was a little disappointed in the clarity of the picture, the set-top box was a bit difficult to use, but it helps that you can control it remotely from your smartphone or tablet. As a result the set-top box has surpassed my expectations for it was taken to view a lot of video from the home server, but the functionality of the device was much broader and as a result this little box has turned a simple TV into a computer controlled by the remote. My point is all this? Read on and you’ll understand everything.

A set-top box for the monitor to receive digital TV

As you see here is the same VGA, but in addition to it there is HDMI. By the way, if you connect the set-top box through HDMI, the sound will go through it. For example my TV set in the kitchen has HDMI, but it has no digital TV and if you connect such a set-top box to it, the sound will come out of the TV set. In addition to all the other things this set-top box is equipped with a USB-jack, so you can watch video from a flash drive and not only.

Just like the first version of the TV tuner for the monitor, the set top box has RCA(CVBS) jacks.

But unlike the first, where it is AV-input, in this case these jacks are AV-output, which means that in addition to the monitor and relatively modern TV sets you can connect this set-top box to very old TV sets.

Features of the console

Since the set-top box receives digital TV, on top of that we get a lot of other great. But first we need to find the channels, it’s an elementary thing. Press “menu” on the remote control and use the volume buttons to select the appropriate menu item. photo):

Choose “auto search” and press the volume up button. We observe the picture:

After a while we will see the found channels and radio stations:

The channel search is complete, as you can see in our city there are 20 channels, in other cities the number of channels may be different.

Press “info” button on the remote control to see what is going on and what will happen next. If you press this button again, you will see more detailed information:

With the up and down buttons we switch between programs and with the yellow and blue buttons we scroll through the description if it is not fully displayed.

To display the program guide, we have to press “EPG” on the remote control:

monitor, computer

Use the “left” and “right” buttons to scroll through the channels and the “up” and “down” buttons to scroll through the programs.

And here is where the most interesting part awaits us. If we press the “OK” button on a program, we will see a strange picture, but if we press the red button, this is what we will see:

This is adding a schedule for recording a show. Press “OK” again and the job will be added to the queue. The most interesting thing is that we can easily turn off the set-top box, it will turn on itself and record the show. The only thing you need to successfully perform this task is the presence of a USB flash drive in the USB-connector set-top box.

The USB stick is also needed for the “timeshift” function, to say “pause”. You heard right, the device can pause the TV. But the box will not be able to keep TV on pause for a long time, because the amount of recordable stream is limited by the settings of this function. The default capacity is 1Gb but you can increase it. This is done in the menu:

For this we have to choose “PVR Configure” and press “OK”.

Select “Record device” and click “OK” again.

Here we choose our flash drive, and below that we set the amount of memory available for recording.

You are probably wondering why you need to choose a flash drive if you have only one slot. Nobody forbids to connect to the USB-hub, and to it a flash drive, an external hard drive and a card reader.


In fact, I presented you not just two ways how to turn the monitor into a TV, but actually more than that. Not only can you turn your monitor into a TV set, but your TV set can be turned into a digital TV receiver, or even into a Smart TV with the Android receiver.

To summarize we can state a wide range of options. The option with the Android receiver is suitable for those who want to turn the monitor into a TV for the kitchen or other rooms where there is access to the Internet. Two variants of TV tuner for the monitor will suit those who do not want to depend on the Internet and have a very simple solution to watch TV on the monitor. The first option of TV-tuner will suit those who want to complement your computer ability to watch TV, and the second option will suit those who just want to give a second life to the monitor and be able to receive digital TV.

Despite the fact that progress is stepping by leaps and bounds, do not throw out, it would seem unnecessary, outdated things, as we see they can serve you more, but in a slightly different quality. All you need to do is buy an additional device and a useless thing becomes not only useful, but gets an incredibly wide range of opportunities.

How to connect the monitor to the computer

So if you do not know how to connect the monitor to the computer, then first of all examine the back panel of your computer. Most likely you will find video outputs (DVI or VGA and HDMI) at the bottom of the monitor’s back panel.

If you find video outputs at the bottom of your system unit these are your graphics card video outputs and you should use them first. If there are no video outputs at the bottom of the system unit, it means that the computer does not have a separate video card and uses embedded graphics. In this case you should use the video outputs at the top of the system unit (these are the video outputs on the motherboard).

Then take a look at the back of the monitor. These days it’s hard to find a monitor without DVI input. But some of the cheapest or older models may not have one. If your computer has DVI output, but your monitor has no DVI input, then you have to use VGA output on your computer and VGA input on the monitor to connect monitor. If your computer only has DVI output and your monitor only has VGA input you can use the adapter.

But in most cases this is not a problem. As a rule, there are both DVI and VGA input on the monitor, and the choice of video interface to connect the monitor depends only on what video outputs your computer has.

In order to connect a monitor to a computer with a DVI or VGA interface, you need to connect the video output of the computer and the video input of the monitor with a DVI or VGA cable (depending on which interface you use). After connecting you need to tighten the two screws that are on the sides of the DVI and VGA cable.

These screws have plastic tips and can be tightened by hand. If you don’t secure the connection with screws, the cable can have poor contact, resulting in flicker on the monitor.

If you use an HDMI interface there is no need to screw in the screws because the cable does not have this feature. In this case you just need to plug an HDMI cable into the HDMI output on your computer and the HDMI input on your monitor.

How to connect two monitors to one computer?

Probably many of you have seen your friends how two monitors work simultaneously from one system unit. But very few people can set it up the same way as their friends. In this article we will learn how to connect two monitors at home. The most important thing for the task is to support this function (presence of two DVI or VGA outputs) in your video card, and of course to have two monitors! I would like to point out that a modern computer is HDMI capable.

Many people have 2 outputs with a DVI connector on the video card:

On top of that there is a component video interface. VGA:

It is not uncommon for video adapters to combine these outputs with each other. This is a common phenomenon. As we remember our main goal is to connect our monitors to these outputs. Since the cords that connect the video card to the monitor, there are different, in case of what you just buy special adapters from VGA to DVI, and the little problem solved.

We will be setting up in Windows XP. So, we will assume that you have connected both monitors and now turn on the computer. After successfully booting the operating system, right-click on the desktop and go to the line Properties.

monitor, computer

After that, we press the button Definition, then we will know which monitor we have as the default. if necessary, change.

Having marked the second monitor, select the item Extend the desktop to this monitor.

At this point the main goal is achieved. two monitors work on one system unit. If all the same problems arise at connection, write to our computer forum, the experts will help you, the main thing correctly to create a theme in the appropriate section.
