Extended information
Display is also often called a monitor. The monitor is an I/O device of the computer, that is, an input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye.
The reasons why the monitor screen often flickers:
1. When the refresh frequency of the monitor is set lower than 75Hz, the screen will often shake and flicker. Increase the refresh rate appropriately. For example, if it is set to higher than 85Hz, the screen shaking phenomenon will generally not occur again.
2. When the power transformer is working, it will cause large electromagnetic interference, causing the screen to shake. Placing the power adapter away from the case and monitor can solve the problem.
3. The magnetic field effect of the speakers will interfere with the normal operation of the monitor, causing the monitor to produce magnetic interference phenomena such as screen jitter and cross-color. Computer splash screens are mostly caused by monitors or graphics cards that do not support high resolution, causing splash screens or overlapping screen avatars. Vague.
1 Poor contact and signal interference;
2 The screen refresh frequency is too low and the graphics card driver;
3 Inferior power supply;
4 Hardware problems and the computer has no sound. The lower part of the computer screen flickers, the screen goes black, and the computer screen shakes. In addition to making your eyes tired quickly, it will also cause eye problems to the user over time. How to check the computer memory. If not solved in time, it will cause damage to your system, because there may be hidden problems in the system itself that are reflected in the screen jitter phenomenon on the computer configuration. In fact, there are many reasons that can cause the screen to shake, and the solution is actually not that difficult.
Cause 1: The document font has a "flash background" set.
Solution: Select the flashing text, right-click, click "Font", click the "Text Effect" tab in the pop-up "Font" dialog box, select "(None)" under dynamic effects, and finally click "OK" ".
Cause two: There is a program error in the word software.
Solution: Uninstall and reinstall.
Reason three: The computer may be infected with a virus.
Solution: Use the latest anti-virus software to thoroughly scan and remove it.
If none of the above methods can solve the problem, it is recommended to reinstall the computer system and then install the word software.
The display screen keeps flickering as follows:
1. The display refresh rate setting is incorrect. If the refresh rate setting is too low, it will cause the screen to shake. The check method is to use Right-click a blank area of the system desktop and click the "Properties" command from the pop-up right-click menu to enter the monitor's property settings window. Click the "Settings" tab in this window, click the "Advanced" button in the corresponding tab page that pops up, open the monitor's advanced property setting interface, and then click the "Monitor" tab, where you can see The refresh rate of the monitor is set to "60", which is what causes the monitor screen to constantly shake. Set the new frequency to above "75" and click OK to return to the desktop. In fact, the main reason for monitor screen jitter is that the refresh frequency of the monitor is set lower than 75Hz. At this time, the screen often shakes and flickers. We only need to increase the refresh rate to above 75Hz, then the screen jitter will not occur. Will appear again.
2. The graphics card driver is incorrect. Sometimes when we enter the monitor refresh rate of the computer, we find that there is no refresh rate to choose from. This is caused by the driver of the front graphics card being incorrect or too old. Computers purchased earlier are prone to this problem. At this time, do not use the driver in the CD that came with the computer. You can download the latest version of the driver for the corresponding display card online, then open the properties window of "System" and click Click the "Device Manager" button in the "Hardware" window to enter the system's device list interface. Right-click the display card option in this interface, click the "Properties" command from the pop-up right-click menu, then in the pop-up graphics card property settings window, click the "Driver" label, and then click on the corresponding label page Click the "Update Driver" button, and then gradually update the graphics card driver to the latest version according to the wizard prompts. Finally, restart the computer system. If the driver is properly installed, the display refresh frequency option will appear, and then refresh Just set the frequency to above 75Hz.
3. Display jitter caused by magnetic field interference. The display is easily interfered by strong electric fields or strong magnetic fields. If the jitter problem cannot be solved by using the two methods introduced above, then it should be suspected that the screen jitter is caused by the magnetic field or electric field near the display. of. In order to eliminate all interference around the monitor, you can move the computer to an empty table, and then perform a power-on test. If the screen jitter disappears, it means that there is strong electric field or strong magnetic field interference in the original place of your computer. , please take suspicious objects (such as speaker subwoofers, magnetized cups, etc.) away from the computer. Then turn the monitor off and on again several times to achieve the purpose of degaussing (current monitors have an automatic degaussing function when turned on). 4. Poor contact of the graphics card. Open the chassis, pull out the graphics card from the slot, and then wipe the dust from the gold finger of the graphics card with your hands. It is best to find a soft fine-bristled brush and gently wipe away all the dust on the surface of the graphics card. Clean it, and then wipe the surface of the gold finger with a clean eraser a few times to remove the oxide layer on the surface of the gold finger. Finally, insert the graphics card tightly into the motherboard slot and fix it to the chassis shell with screws. superior. Turn it on again for testing, and the general fault can be resolved. 5. Monitor aging Sometimes jitter may occur due to the age of the monitor being used. In order to check whether the electronic components inside the monitor are aging, you can connect the faulty monitor to someone else's computer for testing. If the fault still disappears, it means the monitor is broken and needs to be repaired. 6. Inferior power supply or power supply equipment has aged. The components and materials used in many brand-name computer power supplies are of poor workmanship and materials, which can easily cause the computer's circuit to be blocked or the power supply capacity to fail to keep up. When the system is busy, the monitor will especially experience screen jitter. The phenomenon. When a computer's power supply begins to age, it can easily cause the same problem. At this time, the power supply can be replaced for testing.
The reason is caused by network delay or network interruption. Another possibility is that it cannot operate due to insufficient power. Solution:
1. First, find steam on the computer desktop, right-click the mouse and select the location to open the file.
2. Then in the opened folder window, find the folder.
3. Then in the opened page, right-click the mouse and select Delete.
4. Finally, in the window that opens, confirm the deletion and then re-run steam and wait for automatic updates.
When your computer encounters this situation, do not operate it blindly out of anxiety, because your blind operation may cause the system to completely collapse and there is no way to recover from it. There's room. Therefore, first think calmly about what operations you have performed before or what websites you have browsed. Because this situation is most likely caused by a virus. If a virus deletes your system's partition table or system startup files, such problems may occur. We first need to restart. Keep pressing the F8 key when turning on the computer. If a menu with white characters on a black background appears after you keep pressing it, then fortunately, it means that your system is not in serious trouble. We enter the safe mode of the system, disinfect the virus after entering, and repair the missing system files. Then restart the computer and the problem may be solved successfully. If you keep pressing F8 but nothing happens, it means that the problem with your computer is already serious. At this time, if your system has been backed up before, there may be a glimmer of hope. Restart again and keep pressing the up and down keys on the keyboard before turning on the computer. If a system selection menu appears, it means that the problem is still not major. It is just a system problem, not a hardware problem. Select to enter the restore program and perform system restore. After restoration, of course you can boot smoothly. If you can't wake up the black flashing interface no matter what keys you press, it means the problem is terminal. At this step, it cannot be concluded that it is a hardware problem. It may be solved through software operation. At this time you may need to use the pe system. Restart the computer, enter bios, select the USB disk to boot, and enter the pe system. After entering, fix the system problems, either anti-virus or repair. After the repair is completed, restart the computer and the problem may be solved. If you have entered the PE system and restored the system, or even reinstalled the system in PE, but it still looks like this after booting, you should be mentally prepared at this time. Because this may be a hardware problem. But at this step, it is not necessary to send it for repair. You can dismantle the case, remove the hard drive cable, memory, graphics card, CPU, and other large hardware, wipe it, and then install it. Be careful and do not install it again. I violently dismantle the phone out of anxiety, because if a piece of hardware is damaged, there is nothing I can do. Such an operation is relatively risky, but trying it may solve the problem. If this is really the reason, then after you reinstall and restart the computer, the problem may be solved.
