The computer monitor was spent, and the words couldn t be read clearly, what should I do, I was in a

Is it a discrete graphics card, it may be that the graphics card is in poor contact, and after shutting down, unplug the graphics card and use an eraser to reinsert the gold finger of the graphics card, which usually solves the problem. It is also possible that the CPU temperature is too high and the temperature of the graphics card chip is too high, and the possibility of the graphics card is relatively high, clean up the dust in the computer case and check whether the graphics card fan is damaged. Have you updated your graphics drivers recently?

If there is a fault after installing the driver, reinstall the graphics card driver and try it.

Hehe, there's a problem with the graphics card, what you see by yourself is a blurred screen, but when the tiled image is sent, others won't see it. Generally, there are problems with the graphics card, and there are two situations: one is the problem with the graphics card, and the other is that the driver is not installed well. Feel free to ask.

This screenshot is very clear.

It is recommended that you restart the machine to see if there is any change in the effect of the monitor. If it is still a little blurry, it is recommended to stop for a while to let the monitor cool down completely and then restart it to see if it is a problem with the display or the graphics card.

Let's talk about a monitor to try, if it's still a blurred screen, it proves that your graphics card is broken, if not, it means that your monitor is broken.

The ** line behind the computer is loose to see if it is loose, or if you don't turn on the computer and turn on the monitor to see if the display is normal, you have to answer that the display is normal, and the graphics card of the computer is faulty. If the world is still like that, the display is broken, send it for repair.

.There is a mouse right-click on the empty space of the desktop;

2.Select Properties;

3.Select "Settings";

4.Adjust the "screen power resolution";

5.Select "Advanced";

6.Select Monitors;

7.Adjust the "screen power refresh rate", 75 Hz is better;

8.OK, exit. 1。Desktop right-click, Properties, Advanced, Monitor, you can adjust the refresh rate, adjust to 60Hz on it.

2。There is also a heavy possibility that the speaker is too close to the display, magnetic field interference, put it far away and try to adjust the refresh rate of the monitor, the first thing to do is to carefully check whether there is an electromagnetic interference source around the computer, and then replace a graphics card, or connect the monitor to another computer, confirm that there is no problem with the graphics card itself, and then adjust the refresh rate. If the above reasons are ruled out, it is likely that the quality of the LCD is a problem, such as the problem of poor thermal stability.

Water ripple is a common quality problem of LCD displays, which cannot be solved by yourself, so it is recommended to replace or send it for repair as soon as possible.

Some LCD monitors have a blurry screen when they start, giving the impression that there is high-frequency electromagnetic interference, and the handwriting on the screen is very blurry and jagged. This phenomenon is generally due to the fact that there is no digital interface on the graphics card, and it is connected to the VGA interface of the graphics card through the internal digital analog conversion circuit. Although this form of connection solves the problem of signal matching, it also brings the problem of distortion due to interference.

The reason is mainly because the clock frequency of the liquid crystal display itself is difficult to keep 100% synchronous with the clock frequency of the input analog signal, especially when the analog synchronous signal frequency is constantly changing, if the synchronous circuit of the liquid crystal display at this time, or the transmission line connected with the synchronous signal of the graphics card has the problem of short circuit, poor contact, etc., and can not adjust the follow-up in time to maintain the necessary synchronization relationship, the problem of the blurred screen will appear.

In a sense, water ripples are very common in LCD displays; It's just that most of the products are so subtle that users can't notice them.

That's it. If the user can feel the ripples in the water, they may wish to check it by following these steps:

1 Poor contact of the signal connection cable, this problem is the most common, and it only needs to be reconnected to solve the problem.

2. The output signal of the graphics card is unstable, this problem is mostly seen in analog signals, if the display has a DVI interface, it is recommended that the user use the DVI signal cable to connect the display;

3. Problems with the display itself, failure to control the LCD panel during production, and defects in the software program (firmware) of the display may cause water ripple problems. If it is a problem with the display itself, the user has no way to solve it by himself, and he can contact the dealer for replacement or return.

Based on the fault symptoms, confirm that the graphics card driver is not.

If there is a problem, it should be that the screen resolution is set too high, causing a blurred screen, reboot to boot into safe mode, and then enter the "Display Properties" window under the Windows system, pull the slider in the "Screen Resolution" to select the appropriate resolution and press.

under the "Apply" button. After restarting the computer, the glitch disappears.

Note: This type of failure is generally due to the display or graphics card not being available.

If the resolution is too high, you can turn the resolution down after entering safe mode. If the LCD screen is caused by the newly installed graphics card driver, you need to enter safe mode to remove the driver.

Either the graphics card is overheating and the screen is sloppy, or the LCD is leaking.

You can find a normal computer to replace it.

If the monitor leaks, it really can't be repaired, so you can only buy it again.

Is it damp or what, don't believe the guy who repairs the computer, his purpose is that you buy something from him, and the more dead way is to take a blow dryer.

It's really leaking.,You need to change the screen.,Repairing ** is really similar to buying a new one.。

It's either a display problem or a graphics card problem, check the hardware, and reseat the graphics card cable first, if not, it's a hardware problem.

My Lenovo Jiayue 1509 computer has the same problem, the screen is black after the screen, sometimes good and sometimes bad. The system, the drive have all been changed, no.

The main reasons and solutions for the blank screen of the computer display are as follows:

1. Graphics card problems.

Most of the computer screen failures are caused by the graphics card itself, as soon as the display is turned on, check the heat dissipation of the graphics card, touch the temperature of the video memory chip with your hands, and check whether the fan of the graphics card is stopped. Then look at the graphics card slot on the motherboard to see if there is any dust, check whether the gold finger of the graphics card is oxidized, and then clean up the dust according to the specific situation, wipe the gold finger with an eraser to polish the oxidized part. If there is a problem with heat dissipation, change the fan or install a heatsink on the video memory.

Or go into the BIOS and see if the voltage of the AGP is stable nearby.

2. Driver problems.

This is also an important reason for the blurred screen, which mostly occurs after changing the driver version of the graphics card, and may also be caused by the corruption of the driver file. The solution is very simple, reinstall the driver that has passed the Microsoft WHQL certification, and the version does not have to be blindly updated. The first thing to check when the screen is blurred is the graphics card driver, which conforms to the principle of soft first and then hard.

3. Temperature problem.

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

4. Memory module problem.

If it is not caused by the above reasons, you can consider whether it is caused by the damage of the memory module, you can remove the dust on the memory module by wiping, and then turn on the computer to see if the problem of the screen is solved.

5. Data cable problems.

If you are using a desktop, then if there is a blurred screen, then the first thing that should be ruled out is the problem of the data cable connected to the monitor and the host, it may be a loose connection, or it may be a lack of power supply caused by the oxidation of the connector. If reconnecting still doesn't solve the problem, then change the data cable, and if it doesn't work, then consider what other reasons are.

Now I don't know if your computer has a broken driver or a hardware problem.

Drive the elves, go to the house. Update the driver down.

If the screen is still blurred, use Master Lu's hardware detection, and there is a detection screen inside. See if there's a problem with the color or something, if there's a problem with that fixed place, it might be a hardware problem.

It's time to change the graphics card.,Pull the graphics card back and put it back on.,It's not okay to change the graphics card.。

If your monitor has bright spots, bright lines, bright spots, dark lines, dark spots, blurred screens, etc., please observe whether there is the same fault during the boot process or when entering the BIOS

There is no boot process, only when you enter the system, it is a system problem, please reinstall the graphics card driver test;

During the start-up process, it is recommended to replace or plug the signal line for testing; If it is invalid, it is recommended to replace or connect other monitors or projectors and other equipment for testing, if other devices display normally, it proves that your display screen is faulty, it is recommended that you can click on the avatar to enter the "Lenovo Business Service" homepage**Consultation.

Note: If it is a fault phenomenon such as screen leakage and cracking, it is generally not covered by the warranty, and it needs to be subject to the specific inspection by the service station engineer.

Try to drive life and look at the graphics driver It should be able to solve.

1.For soft problems such as graphics card driver and system, it is recommended to update the graphics card driver, otherwise the system will be restored.

2.The soft problem is ruled out that is a hardware problem.,Your symptoms are likely to be graphics card problems.,The weather is too hot and the royal card chip is broken.,Or bad contact.,If you will disassemble the machine, it is recommended to disassemble it yourself.,For example, Chunyanguo will not ask for help from classmates next to you,Because it costs at least 50 yuan to repair the place。。。 It's also possible that there is a problem with the screen, but it is not as likely as the graphics card.

3.Viruses, memory problems, this is not very likely.

ps：1.During the warranty period, go to the shed macro for maintenance after selling.

2.After the warranty, it is recommended to go to the special repair notebook, (Nanjing's to Zhujiang Road), and do not go to the after-sales service, because the after-sales service is determined to be a graphics card problem, 80% will ask you to change the motherboard, so it will cost 800-1000, which is very uneconomical, and at the notebook repair point, ** is generally between 200-300.

3.To deal with the problem, we must first eliminate the soft problem and look at the hardware problem.

After you take the machine apart, see if there is any dirt such as dust at the interface of the graphics card or memory module, and if so, use an eraser to wipe the mount on the graphics card cover (celery memory slip), it should not be.

1.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 blurred screen: When the monitor is set incorrectly in the resolution of Win95, there may be blurry screen failure when starting Windows, that is, the picture is layered, shaky, serious and even black screen of death. Solution:

Enter the setup or enter the safe mode of win95, and reset the display mode of the monitor.
