Wire from the monitor to the system unit. How to connect a new monitor to the system unit. Connecting the network cable to the power supply
Frequently asked question, which arises for beginners, how to connect something to a computer? And in this moment, - everything is outrageously simple, cables and connectors have their own purpose and, most importantly, their own form of connection, and even if you really want to, you won’t confuse them.
To connect the monitor we need two cables that come with it. Look into the box, where in addition to the monitor there should be components for installation and connection (cables, disk, stand):
One cable is used to connect the monitor to the network (outlet) and it looks like this:
There may also be such a cable, it is used to connect to an uninterruptible power supply:
The other one is to connect the monitor to system unit(to the computer itself) and there are mainly two types (DVI and VGA):
If you have just started assembling a computer, then first purchase a surge protector (adapter, tee), with so many network plugs it is simply necessary.
We connect the monitor to the power outlet, press the button in the lower corner of the monitor, the light comes on, everything is fine. Take the VGA cable, connect it to the monitor and the system unit by screwing in the screws on the sides. The connectors on the back of the system unit look approximately as follows (approximately, because there may be different variations):
Turn on the system unit and wait for it to fully boot, insert the driver disk into the drive, it should be included with the monitor and start installing the drivers (the article will help you on how to do this -). The disk will automatically launch the installation wizard, you just have to watch the installation process and agree by clicking on the “next” button.
Also, more advanced users can, after completing the installation, go to the control panel, personalization section, customize everything to your taste - color, design, resolution, etc.
I think we've figured it out how to connect a monitor to a computer, and in the following articles we will connect other devices (input and output).
Previously, connecting video cards to a monitor was done using the VGA video interface. The image was transmitted via an analog signal without sound output. The technology was developed in such a way that VGA monitors could work without problems with new versions of graphics adapters that support large quantity colors. However, this interface has been replaced by new ones, where the signal is output already in digital form. Let's figure out how to connect a VGA monitor to HDMI or another type of interface of your choice.
On older monitors there is only a VGA connector, which previously did not cause problems, because most video cards also had this port. However, with the release of the RX four hundredth models from AMD and the GeForce tenth series from NVIDIA, the developers decided to get rid of the already outdated connection and did not add VGA. Because of this, users have to use converters to connect a new video card to old monitors.
Selecting an active converter
In new video cards, all interfaces are digital, so a regular adapter cannot connect to a monitor. You need to choose one of the most suitable connectors and pick up a converter in the store. Please pay attention to the following details before purchasing:
The vast majority of converters do not require preset and installing drivers, all you need to do is connect and start working on your computer.
Connecting a video card to a monitor via a converter
There is nothing complicated in connecting all the wires, just follow a few steps:
Today we examined in detail the principle of selecting a converter and connecting it to a video card and monitor. If after connecting you find that the image is not displayed or the monitor screen goes dark over time, we recommend reading several of our articles; they will help you find a solution to the problems that have arisen.
Good day, friends! Wireless monitor– although it’s a convenient thing, it’s still an expensive pleasure for most gamers.
I would like to draw your attention to the fact that this is so far: when the first LCD monitors appeared on the market, not everyone could afford them and the majority continued to buy pot-bellied CRTs, but ten years later the situation has changed dramatically.
Today, everything is exactly the opposite: almost everyone uses liquid crystal displays, and cathode ray tubes gradually “died out”, as they are almost never produced or used.
For this reason, most users use wires the old fashioned way to connect the monitor to the system unit.
In this post, let's look at what types of monitor cables there are, which one is best to use depending on the operating characteristics of the device, and how long the wire should be to avoid signal loss and, as a result, picture distortion.
VGA
The oldest format, which was developed in 1989 by IBM for PS/2 series computers. It is logical that at the same time as the slots on the video card, corresponding cables appeared. In older CRT displays, one end of such a cable may be soldered tightly to the board inside.
However, almost all modern flat-panel monitors are equipped only with slots where you can connect the appropriate cable. Sometimes you have to buy it separately: for example, the basic package includes only VGA, but you have to pay extra for HDMI.
A modern cord of this format is equipped at both ends with plugs with special clamps that are screwed into suitable connectors on the video card or monitor.
As a rule, the tips are marked blue. The higher the maximum resolution of the transmitted image, the shorter the permissible length of any wire connected to the computer (not only VGA). In this case, with a resolution of 1600x1200, the length of the wire should preferably not exceed 10 meters.
DVI
It can transmit both digital and analog images. There are several types of DVI ports, each of which should use the appropriate cable. They are equipped with incompatible keys, so you won’t be able to plug an unsuitable cable into the slot.
When transmitting an image with a resolution of 1920x1200, the cable length should not exceed 10 meters, and the active signal equipped with an amplifier should not exceed 61 meters. The connectors of such a cable resemble VGA and are fixed in a similar way, but are usually marked in white or yellow.
HDMI
Suitable not only for a PC and monitor, but in general for any video equipment: home theater, projector and the like. In addition to images, it can also transmit sound. There are three types of incompatible connectors of different sizes, which are usually not color coded - regular, mini and micro. No latches are provided.
The maximum length of a simple cable is 10 meters, and one equipped with a signal amplifier and ferrite filters is up to 35–40 meters. As in the previous case, such a cord is convenient to use in public places: for example, a sports bar for connecting a monitor or a conference room when making a presentation.
Display Port
Not suitable for connecting a budget video card, since they are usually not equipped with such connectors.
Expensive gaming models are capable of delivering maximum results using such a cable, including due to the possibility of activation AMD technologies Freesync and Nvidia G‑sync (this is discussed in more detail in the publication “”).
Today there is only one type of such connector, which also does not have color coding. The maximum length of the wire should preferably not exceed 15 meters. Signal amplification, alas, is not provided for by the design. 
Adapters
If the connectors on your monitor do not match the slots on the video card, you can always find a solution that is not burdensome in terms of cost. For example, there are adapters and adapters VGA-DVI, VGA-HDMI DVI-HDMI, and for any type of connector.
The problem is to “make friends” of the display with an incompatible port, so you should not buy an adapter, but an adapter, the cost of which is usually only a couple of dollars higher.
I recommend keeping a reference point and using HDMI cables, as the most widespread and convenient option. The presence of Display Port, more advanced in technically, not every monitor or graphics accelerator can boast.
HDMI is included in the design of any modern device.
I would be grateful to everyone who shares this publication on in social networks. I hope the information was useful to you. Thank you for attention. Till tomorrow!
After assembling or purchasing a system unit, all that remains is to purchase additional peripherals. The main component is the monitor, because without it you simply cannot work at the computer. It often happens that users have problems connecting these two devices. This time we will try to describe this process in detail so that even novice users can do everything quickly and without errors. Let's look at its stages in order.
We have divided the entire algorithm of actions into steps to make it easier. You just need to follow them and perform each manipulation in the correct sequence, then everything will definitely work out. If you have not yet purchased a monitor, we recommend that you read our article at the link below, which discusses the parameters and characteristics in detail, which will help you make your choice.
Step 1: Preparatory work
First of all, you should understand the equipment package and install it on the work surface. After these steps, you can proceed to the connection itself. The preparatory work looks like this:
Step 2: Connecting the Monitor
The preparations are complete, it’s time to connect to the PC. There is nothing complicated about this; the whole process will take just a few minutes. You will need to do the following:
If your PC does not have a discrete graphics adapter, the connection is made via motherboard using an integrated video card. To display the image correctly on the display, the integrated graphics must be enabled. You will find detailed instructions on this topic in our other material at the link below.
Step 3: Installing Drivers
A common problem when starting a computer is that there is no image on the display. Most often it occurs due to uninstalled graphics adapter drivers. We advise you to pay attention to our other articles to understand the installation of files to the GPU.
If installing drivers did not bring any results, read about possible other problems and their solutions in the next article from our author.
In addition, sometimes the monitor itself requires a proprietary software. In this case, check the equipment package. Usually there is a disk with software there. However, if you can't use it, download the driver using third party programs or through the official website of the manufacturer.
For 10 years now, computers and laptops have been equipped with not one, but two or three types of connectors at the same time. Ports vary in size and appearance. What type of monitor connection do you prefer? The article also discusses the practical usefulness of simultaneously connecting two or even three monitors.
Common but old types of connectors
VGA (Video Graphics Array): an outdated classic
The blue trapezoidal interface dominated the computer field for 25-30 years. It worked great on older CRT displays due to its analog nature. But flat LCD screens appeared - digital devices, then resolutions began to increase and the good old VGA began to lose ground.
Today it is built into video cards less and less often, but many devices (household players, projectors, TVs) are still equipped with support for the hopelessly outdated VGA. Probably, for several more years, the “old man” will remain a not very desirable, but widespread de facto standard - if you have any doubts about which cable you can use to connect the monitor in the next office, then take VGA.
DVI-I (Digital Visual Interface): another long-lived video interface
Actually, there are several of them: DVI-A, -D and -I, plus their varieties. But when we talk about the most common DVI standard, we mean the analog-to-digital DVI-I Dual Channel - it is this specification that is built into most PCs.
At one time, DVI came to replace VGA, which was rapidly becoming obsolete in the mid-2000s. The ability to transmit both analog and digital signals, support for large (in that era) resolutions and high frequencies, lack of inexpensive competitors: DVI continues to serve as the standard today. But it is unlikely that his active “life” will continue for more than another 3-4 years.
Resolutions higher than the minimum comfortable for today FullHD are increasingly found even in inexpensive computer systems. With the growth of megapixels, the once serious capabilities of DVI are ending. Without going into technical details, we note that the peak capabilities of DVI will not allow displaying an image with a resolution of over 2560 x 1600 at an acceptable frequency (above 60 Hz).
Modern video interfaces
HDMI (High Definition Multimedia Interface) – the king of multimedia
The abbreviation “HD-IM-AI”, once awkward for Russian ears, is increasingly entering our lives. Why has HDMI become so popular? It's simple:
- arbitrarily long wires (okay, to be honest - up to 25-30 meters);
- transmission of sound (even multi-channel!) along with video - goodbye to the need to buy separate speakers for TV;
- convenient small connectors;
- support everywhere - players, zombie boxes, projectors, DVRs, gaming consoles– it’s difficult to immediately remember any technology that didn’t have an HDMI connector;
- ultra-high resolutions;
- 3D picture. And yes, it is possible along with ultra-high resolutions (HDMI 4b and 2.0 versions).
The prospects for HDMI are the most promising - development continues; in 2013, version 2.0 specifications were adopted: this standard is compatible with old wire connectors, but supports increasingly impressive resolutions and other “tasty” features.
DisplayPort (DP): A Connector That's Just Becoming Ubiquitous
And DisplayPort is stunningly beautiful in appearance...
For many years, computers were rarely equipped with this direct competitor to HDMI. And - despite the fact that DisplayPort was good for everyone: and support for very high resolutions along with a stereo signal; and audio transmission; and an impressive length of wire. It is even more profitable for manufacturers than licensed HDMI: there is no need to pay the developers of the standard the 15-25 cents that HDMI owners are entitled to.
The DP connector simply had bad luck in its early years. However, computers are increasingly equipped with a pair of Display Ports modern standard version 1.4. And on its basis, another popular standard with enormous prospects was “born”: the “little brother” of the Display Port...
Mini DP (Mini DisplayPort)
Together with HDMI and the completely outdated VGA, the Mini DisplayPort connector is built into almost every computer and laptop. It has all the advantages of its “big brother”, plus its miniature size – an ideal solution for ever-thinner laptops, ultrabooks, and even smartphones and tablets.
Transmitting an audio signal so as not to buy separate speakers for the monitor? Please - how many channels do you need? Stereoscopy even in 4K? Yes, even though the interface will have to flex all its electronic muscles. Compatibility? There are a wide variety of adapters on the market, for almost any other connector. Future? The Mini DP standard is alive and well.
Thunderbolt: exotic monitor connection options
There are others like that. For a year now, Apple, together with Intel developers, have been promoting the fast, universal, but insanely expensive Thunderbolt interface.
Why do monitors also need Thunderbolt? The question remains for years without a clear answer.
In practice, monitors with its support are not so common, and there are serious doubts about the justification of Thunderbolt for video signal transmission. Is it the fashion for everything “Apple”...
Unfortunately, beyond the scope of this article there remains the most interesting opportunity to connect screens to a computer (and even supply power to them!) using the USB 3.0 interface (or, even more interesting, 3.1). This technology has many prospects, and there are also advantages. However, this is a topic for a separate review – and for the near future!
How to connect a new monitor to an old computer?
An “old computer” most often means a PC with a single port – VGA or DVI. If a new monitor (or TV) absolutely does not want to be friends with such a port, then you should purchase a relatively inexpensive adapter - from VGA to HDMI, from Mini DP to DVI, etc. – there are many options.
When using adapters, some inconveniences are possible (for example, there is no way to transmit sound or images with a particularly high resolution via VGA), but such a scheme will work properly and reliably.
Wireless video signal (WiDi)!
There are such interfaces, even several. Intel Wireless Display (aka WiDi, or “Wi-Dai,” no matter how strange it may sound to a Russian-speaking reader): an adapter that costs about $30 connects to the USB connector of a TV or monitor (if the technology is supported by the manufacturer).
The signal is sent via Wi-Fi, and a video image is displayed on the screen. But this is only in theory, and in practice, significant obstacles are the distance and the presence of walls between the receiver and transmitter. The technology is interesting, it has prospects - but nothing more for now.
Another wireless video interface is AirPlay from Apple. The essence and practical application are the same as WiDI from Intel. A little expensive, not very reliable, far from practical.
A more interesting solution, but still not widespread, is Wireless Home Digital Interface (WHDi). It's not exactly Wi-Fi, although it's very similar. wireless technology. Key Feature– a proprietary method of protection against interference, delay and distortion.
Connecting multiple monitors at the same time
Even a novice user can cope with the task of attaching a main or additional screen: connecting a monitor to a PC or laptop is no more difficult than a flash drive. Connecting a monitor to a computer is only possible in the correct way: the connector simply will not fit into a connector that is not intended for it.
An excellent feature of modern video cards and operating systems– the ability to connect several monitors to one signal source (PC, laptop). The practical benefits are enormous, and in two different versions.
1. Image clone mode
The main computer screen operates normally. But at the same time, the image is completely duplicated on a large-diagonal TV and/or projector. You just need to connect the video cable and big screen, and to the projector. Sound is transmitted along with the image if you use modern connectors (HDMI, Mini DP).
2. Multi-screen mode
The resolution of monitors is constantly growing - but there will always be tasks for which I would like to have a wider screen. Calculations in large Excel spreadsheet, or working with a couple of browsers at once; design tasks and video editing. Even typing is more convenient when there is also an additional display next to the main one. “Gap” - the frames of the screens in practice interfere no more than the frames of glasses - after a few minutes you simply don’t notice them. Gamers also like to use several monitors at once - immersion in the gameplay with such a scheme is much more exciting. By the way, some AMD video cards support up to 6 monitors simultaneously (Eyefinity technology made a lot of noise in the IT community 5 years ago).
Picture: this is how you can call up the settings for connecting a second or third monitor: click on “Graphics Settings” from Intel or Nvidia.
How to connect a 2nd monitor to a computer? Insert the cable connector - most likely, the image will be instantly “picked up” by the second screen. If this does not happen, or you need additional settings/ other mode – minute work in graphics driver video cards. To get to this program, just click right click by the Intel, Nvidia or AMD video driver icon - depending on which video adapter is installed in the PC, and select “Settings”. The video adapter icon is always present in the Control Panel, and in almost all cases - in the Windows tray, around the clock.
