Is the computer monitor smudged with vertical bars? Vertical stripes on a computer monitor?

Troubleshooting steps: 1. Driver problems, which are also an important cause of blurred screens, mostly occur after changing the driver version of the graphics card, or may be caused by driver file corruption. The solution is very simple, reinstall and install the official graphics card driver.

Second, the temperature problem, this problem is not only because of the graphics card, processor, memory and even the chipset of the motherboard is too high The temperature will also cause the screen to be blurred, such a situation mostly occurs in summer, but in winter, if the radiator falls off and the fan stops, it is also very likely that the temperature of the hard disk will be too high indoors, which cannot be ignored, it is also not negligible, it is recommended to open the case to check the installation of each radiator, try to open the case to run the game, and see if the screen will be blurred again, If the fault disappears or the time is delayed, it is almost certain that it is a temperature problem.

3. Power supply problems, including the power supply and the AGP PCI-E 16X power supply of the motherboard, if the graphics card does not get sufficient and pure current, it is also possible that the screen will be blurred. The solution is to disconnect non-essential hardware such as optical drives and independent sound cards, reduce the load on the whole machine, and try again.

Fourth, there are many reasons for graphics card problems.

It may be that the gold finger is oxidized or there is too much dust, try to clean it up, and the oxidized part can be wiped with an eraser;

If it doesn't work, it is recommended to contact the dealer for replacement or return to the factory for repair.

Restart your computer and try it.

There is a bright line on the screen, first determine whether it is on or after entering the system.

A bright line appears when the computer is turned on, and the faulty part may be a display or graphics card hardware problem.

After entering the system, it is recommended to reinstall the graphics card driver or restore the operating system.

The detection method is as follows:

1. Replace the display test to see if the replacement display has a similar situation, so as to determine whether the fault is caused by the host part or the screen part.

2. The replacement display is normal, and the basic judgment is that the display is faulty.

3. If there is a similar fault in replacing the monitor, you need to consider updating the graphics card driver, flash plug-in or restoring the system.

When this happens, it should be a faulty computer monitor cable, and replacing one can be used normally.

It's best to shut down the computer and restart it, if there is no problem, it can be solved directly, if you can't turn it off, you can turn it on after the power is off! If it doesn't work, it's going to be replaced.

If the monitor is broken, just replace it with a new one!

1.Streaks on the computer screen: There are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2.Improper display resolution setting causes streaks on the computer screen: When the display is not set correctly in the resolution of win95, there may be a computer screen flower screen failure when starting Windows, that is, the picture is layered, shaking, serious and even black screen of death.

Solution: Enter the setup or enter the security mode of win95, and reset the display mode of the display.

3.Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there is no response to random keystrokes, similar to a crash, processing method: enter modec080 at this time to be solved.

4.Poor heat dissipation effect of the main control chip of the graphics card: This will also cause streaks on the computer screen, and the treatment method is to improve the heat dissipation performance of the graphics card.

5.The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred.

6.Video memory corruption: When the video memory is damaged, there will be a blurred screen when the system boots up.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

The reason for the blurred screen of the computer monitor is 1:

1. If the graphics card is in poor contact, pull out the graphics card and clean the gold finger.

Reinsert (Integrated Graphics.)

Skip). 2. Graphics card cable problem: Replug and unplug the cable to see if there is any change.

3. Graphics card driver.

Problem: Reinstall the graphics card driver.

4. The display screen is broken: replace the LCD screen of the display outside the warranty period or find the seller to pay for maintenance, and find a dealer for free repair during the warranty period;

The second reason for the blurred lines of the computer monitor:

1. Due to poor heat dissipation of the case, the screen caused by the temperature of the graphics card rises.

The solution is to eliminate heat dissipation issues.

2. The solution caused by the graphics card or monitor does not support high resolution:

1) Restart the computer, press the F8 key continuously, pop up the advanced boot menu, select enter to enter the "Safe Mode" to log in to the system, then enter the display settings under Windows, select the 16-color state, click the "Apply" button, and click the "OK" button.

Remove the graphics driver.

Just restart your computer.

3) The graphics card is loose, and after shutting down, unplug the graphics card and re-install it, usually Sun Xiao's pretending can solve the problem.

4) System overheating, including CPU temperature.

If the temperature is too high, the temperature of the graphics card chip is too high. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

The computer monitor has three reasons for the blurred screen

1. Lack of plugins. InstallFlashPlayer (required online**) and K-lite Codec Pack (hard cooktop**required),**Installation can generally be solved.

2. If the graphics card driver is wrong, reinstall the original driver, or you can use the driver to automatically fix it.

The solution to the horizontal lines of the display screen:

1. If the graphics card is in poor contact, pull out the graphics card and clean the gold finger.

Reinsert (Integrated Graphics.)

Skip). 2. Graphics card cable problem: Replug and unplug the cable to see if there is any change. Burn.

3. Graphics card driver.

Power cord or power supply problem: The power cord or power supply may be damaged or unstable, causing problems with the monitor. Check the power cord or change the power supply to 5

Temperature problem: The computer is very hot, causing problems with the monitor, clean the computer radiator or replace the radiator. Hope mine can help you solve the problem, have a good life!

Generally, a reboot can be solved. One of the most common factors in the phenomenon of the screen is the graphics card driver, generally everyone is used to some drivers and upgrade drivers on the Internet, in this case, many times the compatibility between the computer itself and these drivers is not very good. I suggest that you install your own computer brand driver, so that you can avoid the appearance of blurred screens.

The failure of the screen is sometimes caused by the increase in the temperature of the computer, and these temperature increases are generally due to the need for the computer itself to clean up the memory and organize the disk, and generally we can use the computer's own security software and anti-virus software to clean up the computer junk and antivirus. In this way, the phenomenon of general blurred screens will disappear.

Our computer screen may sometimes be caused by the dust of the computer itself, the computer generally needs to clean up the dust, I recommend that you go to the after-sales department to clean the computer, so that it is more thorough. It is generally best to clean the dust once a year, if the environment we are in is not very good and the dust is relatively large, then it should be cleaned once every six months.
