How To Check The Monitor For Performance

How to check the monitor for performance?

So let’s start with the monitor. It is very easy to check its performance. Disconnect from the system unit and connect to a regular power supply. We turn on the monitor. The power light is on, the screen says “there are connections or check the cable.”.

If you don’t see this, try pressing the menu button. If again there are no results, then the monitor can only be thrown away and go for a new one. But if you saw all these inscriptions, then you are in luck with the monitor. But no luck with something else. But with what, we will look further.

The first thing to do is the standard procedure for any failure. resetting BIOS settings. Most often, after this procedure, many problems are solved. In order to perform this operation, I turn off the computer completely, even from the network. Next, we open the processor and find a round battery on the motherboard.

We take it out for a couple of minutes, then insert it back and turn on the computer.

If after that nothing came of it, we inspect and check the entire unit. First of all, we check all contacts. Especially the RAM. It often happens that it is because of her that the computer may NOT turn on. We take out the memory modules. We examine their contacts, if necessary, then clean. You can clean them gently with an eraser. We put it back. We check the cable contacts, which connects the monitor to the processor.

Clean the entire processor from dust. Slots where memory is inserted, fans. They are generally very clogged with dust. We check the connection of the card. We also take out and clean.

We remove the power supply. It clogs up very heavily with dust. Therefore, it must be opened and carefully cleaned.

So, we checked everything, cleaned it up. And nothing works. The processor fan seems to be buzzing. it turns on. But the monitor screen is still black.

Checking the monitor at home after use

By purchasing a used device from your hands, you risk much more than buying a new one. Here, faults can be both explicit and latent. Therefore, you will have to test the used device more thoroughly. And there are practically no guarantees.

After carrying out the same diagnostics that you do when buying a new monitor, you should also:

  • Inspect the mounting bolts on the rear wall. If the paint on them is knocked down, the threads are scratched, or there is other evidence that they were unscrewed, then the device was disassembled and repaired. Provided that the equipment is purchased in the workshop, this is not so critical, because the repairmen give a guarantee against repeated breakdowns. But if the purchase is from a private person, then you should beware, because the breakdowns could be hastily eliminated, just to sell the equipment.
  • No matter how strange it sounds, smell the monitor. If there is a smell of dampness, then it was stored in a garage or shed, which invariably leads to oxidation of contacts and damage to microcircuits. If you smell the burnt rubber, then the device has been exposed to excessive voltage and it is not known how damaged it is inside.
  • Shake the device. If suddenly something rattles inside, it means that the equipment was dropped and it is not worth buying.

You should also turn on the monitor for a while in a dark room, then turn it off and look at the screen. If light or multi-colored glare and spots gradually disappear there, then the device’s service life is coming to an end, and it has already exhausted its resource.

What is monitor health

Efficiency is the ability of equipment to perform its functions in full. Correct functioning depends on:

  • The integrity of the case, buttons, screen and network cable;
  • Safety of internal wiring, boards, microcircuits and connectors;
  • Correct operation of the processor and software that allows the monitor to properly connect to the computer.

It is these basic parameters that give an idea of ​​how efficient this technique is, or its place in a landfill.

Before buying a computer system unit, you can be more or less sure of its quality and safety. But, nevertheless, you should check its performance. For this you need:

  • Carefully inspect the case, screen and power cord, press the buttons, shake the connectors on the rear wall. If chips or cracks are found on the case, then the monitor was dropped during transportation. One cannot be sure of the performance of such a device.

Checking the power supply

Well, the last thing to be checked is the power supply.

For this, we will also need a working power supply. We open the computer, disconnecting all the connectors of the tested power supply from the motherboard and connect the worker instead. After that, turn on the computer. If everything worked, then the reason is in the power supply. If nothing happened, then the problem is in the motherboard and you will need to change it.

Here, in general terms, a scheme for checking the performance of both the computer itself and its SEPARATE elements.

If, when you turn on the computer, the monitor does not turn on, but the indicator blinks. Advice, if you turned on the computer, and it either did not turn on, or the monitor did not light up, turn it on again and carefully listen to how it hums and how many times it “beeps”.

By the number of Pisks, you can determine the error code. There are a lot of descriptions of THESE codes everywhere, and it will not be difficult to find them.

When buying a new monitor, or when purchasing a used one, the question often arises: does it work as it should, and will it break soon? We will try to figure out how to protect ourselves from buying faulty equipment.

Installing an Intel Xeon LGA771 processor on a 755 socket. How to check if the monitor works without a computer

Today we will analyze a situation when you turned on your computer, the processor started working, but the monitor remained black. This is, of course, not pleasant. Some people have a feeling of panic that everything, the computer “flew”, needs repair or, in general, they will have to buy a new one.

Who else has NOT encountered a similar problem, Do not rush to despair. Not everything is lost. Of course, one cannot do without repair or acquisition here, but the scale is not as serious as it might seem at first glance.

There can be several reasons for this problem. But, conventionally, they can be divided into two categories: either the problem is in the monitor, or in the processor itself (but here anything can be).

map. the likely reason why the monitor is not showing an image

There remains one more option and, most likely, it will be correct. the card burned out. True, the probability of this breakdown is not so high. Maybe, of course, the map is whole. But in this case, the matter is already somewhat more serious. you need to change the motherboard itself.

How to check the card? Remove it from the slot, check the contacts and reinsert it.

If you have a second computer at hand that supports the card being tested, insert it there and turn it on. If the computer boots up normally, then the problem is not with her. If nothing happened, change the card. This option is acceptable only if you have at hand where to check the map.

If not, then a master is needed. In general, if you have a gaming computer, and you strongly “strain” the card, then it is recommended to periodically diagnose it so that it does not fly at the most inopportune moment. There are a number of programs for diagnostics, among which one of the most popular is FurMark

How to check the laptop matrix for performance?

If the laptop screen fails, and various problems occur during image transfer, it is necessary to correctly determine the cause of the malfunction. Disruptions in the display of the picture occur due to chip malfunctions, malfunctions of the card, failure of the loop or malfunctions of the matrix, it is important to correctly recognize the symptoms. The most reliable way is not to waste time on independent repair attempts and immediately contact the service center, however, some problems can be recognized on your own. How to check laptop matrix?

Ways to check the laptop matrix

The matrix is ​​one of the most expensive components in a laptop. It is a liquid crystal display equipped with a lamp or LED backlight and an inverter. Problems most often arise due to careless handling and mechanical damage, but often they are caused by wear of components or factory defects. How to check the laptop matrix for operability and make sure that the reasons for the image violation lie in it?

  • Connect the laptop to an external monitor using the VGA connector: if the picture is displayed normally, then the problem is not with the processor or the card. Most likely, either the matrix itself or the loop is damaged. Exceptions to this rule are possible, but they are quite rare.
  • See how the image changes when you open and close the laptop lid. This is one of the ways to check the flex cable of the laptop matrix, in case of malfunction, the image changes greatly when opening and closing the display.
  • The matrix can be checked for bending and twisting. this method requires extra care. If, with a slight bend, there are sharp changes in the image, the matrix needs to be replaced.

Typical malfunctions of the laptop matrix

You can list a few of the most common breakdowns that laptop owners of almost any brand face. The most reliable components fail sooner or later and require replacement; it is important to recognize the causes of the malfunction in time. The main alarming symptoms:

  • The image on the screen becomes barely visible. The picture is so faintly visible that it seems as if the laptop does not turn on at all. This condition indicates whether it is not a matrix breakdown, but a malfunction of the backlight system, most often it occurs due to a breakdown of the inverter. Before the transformer fails, the screen usually starts dead, while the laptop is running, extraneous noise appears. The solution to the problem will be to replace the inverter in the service center.
  • A distorted picture on the screen, manifested by the appearance of colored vertical stripes. Such a picture arises due to a breakdown of the matrix itself or a loop; accurate diagnostics can be carried out only in a service center. Since the matrix is ​​expensive, it is highly discouraged to change it yourself without experience and Special knowledge.
  • The screen is completely black or completely gray. This situation most often occurs after a serious blow or fall, as a result of which the matrix is ​​completely out of order. The laptop must be checked by connecting to an external monitor: if there is an image on it, then the matrix will have to be completely changed.

The monitor does NOT light up

There are many reasons for this error, and many solutions. I’ll write about my case. What lessons did I get from there, what I understood and what methods of elimination did I find.

You all know that I have two monitors connected. When I recently arrived from Rostov, I came to my workplace, I start my computer. The system unit is working, and the monitors are commenting. Fuck, I thought. What am I supposed to do? Well, it can’t be that two monitors broke down at the same time. I started digging.

I climbed into the past, and remembered that before leaving, I turned off everything, including the electricity of the entire apartment. And this means that they simply could not burn out from the stress. And when I turned off the system unit for the last time, everything worked perfectly.

Therefore, the first decision I made was, of course, to look at the contacts. I began to take turns disconnecting and reconnecting the cords that power the monitor and the system unit. I even pulled out the cable by force, which, in my opinion, could also be the reason. I don’t know why, but as they say, anything can be.

Then I pulled out the card and put it back in. At the same time, I processed the contacts with a stationery eraser. Gently and neat.

Be sure to blow through the connectors on the motherboard where the card is connected.

After all the operations done, the monitor did not turn on, I began to figure out further why the monitor did not light up.

The monitor does not turn on when the computer starts up. What to do if the monitor does not show an image, but the light is blinking and the computer is working

Today we will analyze a situation when you turned on your computer, the processor started working, but the monitor remained black. This is, of course, not pleasant.

How to check your monitor

Often purchasing a computer, we pay more attention to one part of it. the system unit, while reducing the importance of the other. the monitor. But a flawlessly functioning monitor, configured in the correct way, is very important not only for maintaining visual acuity, but also for a comfortable pastime at the computer. It is important to check how the monitor works before purchase and during use for its correct setup.

There is usually no problem with checking for external flaws. But how do you know if there is a hidden marriage? After all, the most common defects are associated with the operation of the monitor matrix, for example, the presence of dead pixels or a slowed down speed of the matrix reaction, which you will not notice at first glance. For this purpose, special programs have been developed, as well as online services, which are able to quickly and accurately test the monitor.

READ  Monitor Does Not Work Button Is Off

One of the most popular programs for testing monitors is the TFT test utility. Its convenience is that it does not require installation, you just need to download the file with the program, and the interface is intuitive and simple. In the arsenal of the program there are several tests that you need to run sequentially.

The first of the tests. “Shaded screen”. is to fill the screen alternately with different colors, which allows you to identify pixels, and not responsive to color changes. they will glow white or black. The following tests are designed to verify that the monitor reproduces color gradations (Diagonal, Stepped Gradient), image clarity (Lines, Grid, Circles, Patterns) and text readability, as well as the response speed of the monitor matrix ( “Moving square”). The slow response rate of the matrix is ​​evidenced by the “tail” that appears when the square is moved.

There is a menu on the main page where you need to choose how it is convenient for you to test: HTML-Window. the page with the test will open in the current browser tab; HTML FS. a new window will open; Executable mode. an option that allows you to download the program to a physical medium and then NOT use the Internet; Input lag test. designed to test the operation of two monitors working in pairs. It is also possible to test a smartphone, tablet or TV. Run the test and immediately you will see a black and white scale, allowing you to check how the grayscale is displayed. To continue, Move your mouse pointer to the top of the screen. a pop-up menu will appear with various tests. By the way, there is also a hint window with explanations for each test, however, only in English.

With the help of such simple programs, you can accurately check the monitor for various defects and incorrect settings.

How to check the monitor for performance?

After buying a new or used monitor, you need to check it for performance. This can be done by following these steps:

  • Examine the monitor and cables for mechanical damage;
  • Connect the monitor to your Windows PC and turn them on. A working monitor, even a new one, may have dead pixels.

A pixel is the smallest composite of a display; the diagonal of the monitor depends on the number of these elements. Pixels are responsible for color rendition and display of the image as a whole. A dead pixel is a continuously burning pixel. The color of this pixel can be different: white, red, blue or green. The pixel may not burn at all, or it may have other defects. A whole section of dead pixels is also possible.

For a quality check, it is recommended to use special programs that will help detect the presence of dead pixels by switching colors. One of the most convenient and simple is the Tireal TFT Test program.

After the program is launched, you will see several buttons with different tests.

Primary color test helps to check if all pixels are displaying red, white, black, blue, green and pink colors.

Thus, it is possible to identify the presence of dead pixels. If you wish, you can use the rest of the tests, which will measure other indicators of the monitor’s performance.

Noise test helps to check for noise or absence.

The grayscale test determines if all shades of gray (i.e., colors from white to black) are displayed correctly.

RGB test is useful primarily for people working with graphics and corresponding editors.

This program helps to check the monitor for dead pixels, flare (it is recommended to check using the Test of primary colors. black), Tinto (when the monitor is filled with the same color, different areas have different shades; it is recommended to check using the Test of primary colors. gray).

In principle, these tips are also suitable for checking the monitor at home, so anyone can use them: the owner of a new monitor or just wanting to buy it.

  • flickering PWM. If the monitor is very dead, then when working with it, your eyes will quickly get tired and even a headache is possible. To check if the monitor flickers a lot, lower the brightness and contrast in the settings. so this defect will be clearly visible;
  • artifacts. To make sure that they are absent, you need to run any dynamic one and see if there are trails after objects with a fast pace of movement. It may also indicate a malfunction in the card;
  • viewing angles and glare. This is the easiest to check, since it is enough to look at the monitor from different angles: right, left, top, and possibly even below. Glare can be detected by shining a flashlight on the monitor from different angles;
  • sounds. Listen for a quiet monitor. If during operation even a weak squeak or similar sounds emanate from it, then this is NOT an indicator of a well-assembled monitor. You can also change the brightness settings and listen to the monitor.

map. the likely reason why the monitor is not showing an image

There remains one more option and, most likely, it will be correct. the card burned out. True, the probability of this breakdown is not so high. Maybe, of course, the map is whole. But in this case, the matter is already somewhat more serious. you need to change the motherboard itself.

How to check the card? Remove it from the slot, check the contacts and reinsert it.

If you have a second computer at hand that supports the card being tested, insert it there and turn it on. If the computer boots up normally, then the problem is not with her. If nothing happened, change the card. This option is acceptable only if you have at hand where to check the map.

If not, then a master is needed. In general, if you have a gaming computer, and you strongly “strain” the card, then it is recommended to periodically diagnose it so that it does not fly at the most inopportune moment. There are a number of programs for diagnostics, among which one of the most popular is FurMark

FurMark is a specially designed program that stress tests a card that is compatible with the OpenGL API. The peculiarity of this utility is a flexible settings menu in which you can set many functions. The program includes the latest versions of the GPU-Z and GPU Shark additional utilities. Using FurMark is a good test of card performance.

The monitor does NOT light up when you turn on the computer, why and what to do!

Many people ask why the monitor does not light up when the computer is turned on. What to do and how to be. Let’s figure it out.

Hello dear friends, subscribers, and blog guests. Have you ever met a situation on your way when the monitor simply did not turn on when the computer was turned on? The fans have started, the indicators are on, and the monitor is not alive.

This is a very common reason that many computer users have and this is normal. Iron is iron. Our task with you is to know why this is happening, and what needs to be done in order to quickly fix this problem.

This is the topic I would like to devote to today’s article and answer the question of why the monitor does not light up when the computer is turned on. The topic is quite serious, so treat it with understanding and read the article to the end.

We have already talked about errors of this kind in some articles and will continue to do so in future ones. Therefore, in order not to miss this material, subscribe to the blog update.

Well, what I wanted to say, I said. Therefore, you can begin to study this problem, as well as solve it. Don’t forget to leave comments, ask questions and complement each other.

What is monitor health

Efficiency is the ability of equipment to perform its functions in full. Correct functioning depends on:

  • The integrity of the case, buttons, screen and network cable;
  • Safety of internal wiring, boards, microcircuits and connectors;
  • Correct operation of the processor and software that allows the monitor to properly connect to the computer.

It is these basic parameters that give an idea of ​​how efficient this technique is, or its place in a landfill.

Before buying a computer system unit, you can be more or less sure of its quality and safety. But, nevertheless, you should check its performance. For this you need:

  • Carefully inspect the case, screen and power cord, press the buttons, shake the connectors on the rear wall. If chips or cracks are found on the case, then the monitor was dropped during transportation. One cannot be sure of the performance of such a device.

How to check the monitor for performance

When buying a new monitor, or when purchasing a used one, the question often arises: does it work as it should, and will it break soon? We will try to figure out how to protect ourselves from buying faulty equipment.

Checking the monitor at home after use

By purchasing a used device from your hands, you risk much more than buying a new one. Here, faults can be both explicit and latent. Therefore, you will have to test the used device more thoroughly. And there are practically no guarantees.

After carrying out the same diagnostics that you do when buying a new monitor, you should also:

You should also turn on the monitor for a while in a dark room, then turn it off and look at the screen. If light or multi-colored glare and spots gradually disappear there, then the device’s service life is coming to an end, and it has already exhausted its resource.

TOP-10 faults

Consider the most common monitor breakdowns.

  • often than not, the device simply won’t turn on. This can be for a number of reasons: a faulty network cable, and broken buttons or connector, and internal problems in the power supply, wires or microcircuits.
  • The monitor lights up, then ripples or goes out. Also a fairly frequent breakdown that requires the attention of a specialist.
  • During operation, the screen suddenly goes out. As a rule, here we are talking about breakdowns in microcircuits, or broken connectors.
  • There is a picture, but the backlight does not work. Such a breakdown is typical for old-style equipment.
  • The appearance of vertical stripes on the screen signals a damaged loop between the matrix and the screen.
  • Horizontal stripes, squares, and spots on the screen are the result of being hit or dropped.
  • Instead of a picture, we observe the “Malevich square” with or without illumination, gray or white. This indicates a malfunction of the image matrices.
  • The buttons don’t work. This problem is often solved with super-glue, if the board itself and the contacts are intact.
  • A dim backlight signals the imminent failure of the backlight lamps, which should be replaced.
  • Visual noise, tremors, blurry edges of the picture and flickering are a sign of a broken cable between the computer and the monitor or loose connectors.

No matter how insignificant the breakage in the monitor may seem, you should not fix it yourself by watching a couple ofs on YouTube. It is better to consult a specialist, because a minor malfunction may turn out to be a symptom of more serious breakdowns.

Contrast and brightness

Contrast and brightness of the monitor. these are two interdependent concepts that cannot be considered separately from each other. They have the same effect on human vision as flicker. To understand whether the optimal brightness level is set on the monitor, it is necessary to conduct a test with a picture. The image should look like this: on a gray background there are four rectangles of white, red, blue and green colors, which in turn are divided into squares. If you can see a clear border between These squares, then the brightness and contrast are set correctly. if the border is blurry or the squares completely merge into a one-color rectangle, you should go to the screen parameters and adjust the settings.

What tests are worth conducting and what to look for

Since it is possible to fully test the monitor for operability only at home (after all, it will take a lot of time), you will need to continue testing immediately after connecting the screen to the computer. Explore the options for managing settings, read the list of specifications declared by the manufacturer, and highlight the most important: color rendition, contrast, sharpness, etc. It is these parameters that are subject to testing.

Monitor check: highlights

Highlights are very common on both IPS and TN matrices. It is difficult to notice this defect in bright light in the room. If, when viewing photos or pictures with a dark background, you see white spots on the screen, these are flashes. They become noticeable in medium room lighting or in the dark. Therefore, it is better to inspect the purchase for the presence of light in the evening. The main prerequisite for the appearance of such a defect is the tight fit of the matrix to the backlight, therefore it will not be possible to fix this with the help of special software.

Geometry and meshes

The geometry and grids of the monitor should be checked to ensure that screen distortion is present or not. To check the geometry, use the Nokia monitor test program, if you cannot download it, open an image where the background will be evenly divided by contrasting lines. Attach A4 sheet to the monitor and see if all the lines are straight. If the lines are convex, screen distortion is present.

You should also check your monitor for Image Clipping. If the settings are incorrect, the display does not show the entire image that comes from the graphics card, some pixels are not reproduced. Run the test on monteon or Nokia monitor test.

How to check your monitor: dead pixels

Pixel. it is the smallest part of the display, a point on the monitor that can glow in any color depending on the picture being reproduced. When this point begins to constantly perceive one color (black, white, blue, green, etc.), without changing, it is called a broken pixel. One such part of the role is not played, you can easily work with it at the computer. However, if there are more of them, it is distracting and annoying, because you will NOT be able to see the full picture.

There are several types of dead pixels:

white point on a dark background;

black point on a white background;

It is very difficult to notice such a defect during a regular inspection of the monitor, therefore special programs are used to identify dead pixels. One of the most common is Dead Pixel Tester. You need to download it, unzip it, run it. After that, a plate with the name Select color will appear, in which there are about 16 different colors to choose from. Sequentially choose each of the shades and carefully look at the monitor, which will be completely painted in the selected color. If there is a broken pixel, it will show itself in some of the shades, if it is not, then the screen will be evenly colored.

You can try to remove broken dots using utilities (JScreenFix, Bad Crystal, etc.). A positive result is obtained in most cases, however, there are breakages when a dead pixel cannot be healed.

How to check the monitor upon purchase

Examine the monitor and cables for visible mechanical damage;

look at the switched on monitor from different sides to determine the viewing angles;

turn on the flashlight on your smartphone and point it at the screen to check the glare bridge;

listen to the working monitor, it should not give out strange sounds (hum, loud noises, etc.).

It is worth remembering that this is a superficial check, a more thorough research can be done at home after connecting the monitor to a computer.

How to check your monitor. Shimmer

Shimmer. it is an irregular change in the refresh rate of the screen. Dead people can be both expensive and cheap monitors of different years of manufacture, because this deviation is NOT related to the novelty or type of backlight.

Reasons for flickering:

the screen refresh rate is set too low;

malfunction of the graphics adapter or matrix;

damage or lack of installation of the graphics driver.

In most cases, we can NOT guess that the monitor has such a defect, because it is difficult to determine upon examination. However, flickering during prolonged work at the computer is a prerequisite for deterioration of vision, dry eyes, pain in the eyes, and rapid onset of fatigue. Therefore, it is important to check the monitor for flickering. To do this, you need to download several specially designed pictures and expand them to full screen. Up close, the image should have a pattern of alternating black and white small dots, in the distance it should look gray. If this is not the case, then the screen will need adjustment.

gradients

Checking gradients can help you determine the display quality of your monitor tones. This is important for rendering a realistic picture when watching movies or when working with. photographs. To find out whether the monitor reproduces colors correctly, you can use the monteon program. The test is a Screen template with a smooth color gradient. You need to expand the picture to full screen and look at it from different angles. If the color transitions are displayed smoothly, without streaks or abrupt changes in shades, this is a good monitor.

There is also a grayscale test. This is a picture with a smooth transition from black to white. The more shades of gray without streaks the screen can display, the better the picture quality.

Some monitors with incorrect color reproduction and incorrect gradient can be adjusted. To do this, just use the image settings. Specialists who are engaged in retouching should either seek help from a computer wizard or purchase a special device. calibrator.
