Do you know what went wrong with the laptop screen?

The first reason for the computer screen is that the line is faulty.

Line faultIn the problem of computer screen, the fault is mainly manifested in the unstable operation of the computer screen, with continuous shaking and periodic screen dimming. When we determine that the cause of the fault is a wiring problem, we need to check whether the connection between the power cord and the monitor connector is loose, and see how good the power cord is. Because these are the causes of poor circuit contact, doing these things can help troubleshoot.

Reason 2: The data cable is loose.

Because in long-term use, we may be moving the computer desk or forcibly pulling the power cord of the computer while using the computer, especially in the case of playing games, the link line of the keyboard and mouse is often affected and pulled hard. In this case, there are also cases where the data cable is loose and the screen is blurred, but we only need to reinstall the data cable.

Reason 3: Graphics card problem.

The graphics card is an important part of the computer. If there's a problem with the graphics card, it's not at all surprising that something is wrong with the display of your computer screen. Therefore, if you encounter the problem of a blurred screen in use, you can check whether the graphics card of the computer is stable and loose.

At the same time, we should also clean the computer frequently, so that the computer runs faster and maintains a dust-free state.

Reason 4: Software setting problem.

Because different computer software may have different requirements for computers, especially in some software that requires high computer resolution. When our computer configuration cannot meet the needs of this kind of software, it is normal for the computer to have a blurred screen. The quickest way to solve these problems is to uninstall the software or adjust the standard of use of the software.

Your phenomenon graphics card or screen problems are possible, it can only be said that the screen may be larger, and it is finally determined that you need to install a good screen comparison style, and the external screen has little reference value, because the external output and the notebook screen output are two independent output modules.

Solve the hardware failure of the notebook, and you are welcome to ask directly if you have any questions.

Did you shut down and reboot? You first shut down and reboot, and if it doesn't work, then you'll need to reinstall the system.

The note is blurred.,It must be a problem with the screen.,The current LCD screen is easy to have problems.。

Generally speaking, the laptop screen is tossed by itself.,It may be knocked.,There may be voltage instability and the like.,Basically, the possibility of it being bad is very small。

A: It is estimated that there is a problem with the hardware and needs to be repaired.

It may be the configuration of the notebook, and there are problems with some internal debugging, you can refer to the manual or go offline. Carry out some repairs.

Everyone is familiar with computers, it is the most common electronic device around us. When the computer is in use, the display screen is prone to failures such as blurred screens, which is very annoying, so what is the reason for the blurred screen of the computer monitor? Next, I will explain to you how to deal with the blurred screen of the notebook screen.

In the daily use of the computer, the dead screen is often encountered, and in the graphics card maintenance, the flower screen failure is also the most, the graphics card repair for many people feel difficult to repair and have no way to start, many maintenance personnel see the flower screen is also a headache, in fact, find the cause of the flower screen, the problem will be solved, below, share with you the experience of solving the laptop screen screen.

It won't be a software problem, it should be a hardware problem.

Causes and solutions for laptop screen blurring.

1. Graphics card problems. The poor heat dissipation effect of the control chip of the graphics card may lead to the phenomenon of a blurred screen, and it is generally possible to go to the after-sales center to improve the heat dissipation of the computer to return to normal.

2. Virus problems. Some computer viruses will also cause the problem of the computer having a blurred screen, so go to the after-sales service and use professional antivirus software to try to kill the computer in all aspects.

3. Destruction of video memory. After the video memory is damaged, when the system starts, there will be a blurred screen and other phenomena, and generally only a new video memory chip can be replaced.

4. The screen itself is a problem, and if this problem occurs in the notebook repair center on the 17th floor of Silverstone Plaza, Hongxing Road, the computer screen needs to be replaced.

Don't laptops need a graphics card? The vase is, of course, a problem with the graphics card.

Troubleshooting steps: 1. Check whether the power supply is normal and stable;

2. Whether the machine has done a memory upgrade, unplug the memory and use alcohol and eraser to wipe the memory gold finger.

4. Replace the pure version of the system to see if it can solve the problem;

5. If there are conditions, confirm the external monitor, see whether the external screen is blurred, if the external display is normal, you can judge that the screen part of the failure is likely, it is recommended to go to the after-sales specific test.

6. If the machine is overheated, it will also cause a blurred screen, so you can clean the fan and reduce the CPU working temperature.

7. In the power-on state, adjust the display angle of the screen to observe whether the fault has changed or returned to normal? If you can, you can use it temporarily and wait for the free time to contact the service station for further detection of the possibility of improper screen wiring.

If it doesn't work, please go to the after-sales service for specific testing.

1. Graphics card problems. The poor heat dissipation effect of the control chip of the graphics card may lead to the phenomenon of blurred screen, and generally improve the heat dissipation of the computer to return to normal.

2. Virus problems. Some computer viruses can also cause the problem of the computer having a blurred screen, and the fault can be eliminated by using professional antivirus software to disinfect the computer.

3. Drive problems. The reason for the blurred screen may be that the driver is not compatible with the chip, or it may be that the driver is damaged, lost or missing, you can try to reinstall the driver.

4. Third-party software. When some third-party software is opened, the computer screen becomes abnormal, the screen is blurred, or even crashes, which is generally caused by the high frequency of software video memory, try to reduce the frequency and give it a try.

5. Destruction of video memory. After the video memory is damaged, when the system starts, it will be out of the book without a blurred screen, and generally only a new video memory chip can be replaced.

6. Outdated memory. When the computer's video memory is obviously outdated and cannot match with the host, it will also produce a blurred screen, and at this time, you will either replace the more advanced video memory or reduce the speed of the host.

Solution 1 for laptops that often have blurred screens:

1. The case heat dissipation is not good, and the screen is blurred caused by the temperature of the graphics card.

The solution is to eliminate heat dissipation issues.

2. The solution caused by the graphics card or monitor not supporting 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.

2) Restart the computer, in Windows normal mode, enter the Device Manager, delete the graphics card driver, and restart the computer.

3) The graphics card is loose, and unplugging the graphics card and reinserting it after shutting down usually solves the problem.

4) The system is overheating, including the CPU temperature is too high and the graphics card chip is too hot. You can install cooling fans in the appropriate locations in the case, or place the case in a well-ventilated area.

Secondly: First, the main control chip of the graphics card has poor heat dissipation effect.

This will also produce a blurred screen failure. Solution: Improve the heat dissipation performance of the graphics card.

Second, the video memory speed is too low.

When the memory speed is too low to match the speed of the host, the screen will also be blurred. Solution: Replace the video memory with a higher speed, or reduce the speed of the host.

3. Video memory is damaged.

When the video memory is damaged, the screen will be blurred and confused when the system starts. Solution: The video memory chip must be replaced. Note that some video memory is integrated into the graphics card chip, so the graphics card chip must be replaced.

Fourth, the cause of the virus.

Blurred screens can also occur during certain virus flare-ups. Solution: Use anti-virus software to eliminate it.

Solution 2 for laptops with frequent blurred screens:

1.Graphics driver.

Check whether the graphics card driver of the computer is normal, and if there is a problem with the driver, follow the new driver.

2.Whether the graphics card's fan is stalled.

Listen to see if the graphics card fan is stalled or if the fan sound is normal.

3.Graphics card overclocking.

Working at too high a frequency will cause the life of the graphics card to be greatly reduced, which will cause problems with the display of the computer.

4.Use software rendering instead of GPU rendering.

Open the browser, Tools - Internet Options - Advanced - Accelerated Graphics - Render with Software without GPU (tick) - Apply - OK.

This results in better software compatibility and graphics.

5.Hardware acceleration.

Flower screen? First of all, it is interpreted.

First, the system is damaged, the hard disk is damaged, the notebook does not recognize the hard disk, etc., the memory problem or the memory slot is soldered, and the second is the motherboard power supply chip problem, and the BGA (north and south bridge, graphics card, network card, etc.) packaging chip virtual soldering damage will cause the boot screen not to light up.

Your blurred screen should not be caused by overheating and virtual soldering damage of the graphics card BGA packaging chip, it should be a hardware failure, send it for repair and solution. If it is within the warranty period, the drop-off service is free of charge.
