1. Maybe you can just remove the graphics card and wipe it with a leather towel. It should be caused by poor contact of the graphics card. of. After turning on the machine, do you hear a whistle, such as a long beep or something like that? Or drop it and start normally. The other thing is, if there is an independent display or a integrated display, the monitor connector is connected wrongly. If there is an independent display, it must be connected to the independent display.
2. Solution: If the display is damaged, you need to contact after-sales or replace the display. If the problem is with the cable, you can re-plug the cable firmly. If that still doesn't work, you can try replacing the cable.
3. Solution: Repair the monitor or replace it with a new one. electricity failure. If the screen does not light up, but the computer indicator light responds, and if you can see a faint image when shining a flashlight, just change the backlight.
1. Grayscale refers to the brightness level. Taking an 8-bit panel as an example, it can show 256 brightness levels (2 to the 8th power). We Just call it 256 grayscale.
2. Open the Xiaomi laptop and click Settings. Click on the screen display settings, find the time display and click to enter. Find the grayscale response of Xiaomi TV and set the time to 2ms.
3. From all black to all white, the liquid crystal molecules face the largest twisting angle, and a larger voltage needs to be applied. At this time, the liquid crystal molecules twist faster.
4. It is better to slow down the grayscale response time of Xiaomi monitor. The grayscale response time of the Xiaomi monitor LCD screen is over 8MS. It is no problem to play games and watch movies, so there will be no tailing phenomenon when the screen is slowed down. Xiaomi Technology Co., Ltd. was established on March 3, 2010.
1. IDE bus problem: Unplug the hard disk and optical drive cables, and plug them in again 3. Graphics card problem: It may be broken, resulting in no display when booting 4.
2. The graphics card has poor contact. Shut down the computer, unplug it again, clean the PCI-E slot of the graphics card or plug it in again with the gold finger of the graphics card. The rated power of the computer power supply is too low. Generally speaking, the power consumption of computers with more than four cores and independent power supply is relatively high. It is also common for computers with poor power supply to be unable to drive the graphics card.
3. You can first restore the motherboard BIOS to default. Secondly, check the graphics card slot of the motherboard to see if paper scraps or the like have fallen into it. In short, the motherboard is highly suspected. It is also possible that the graphics card power supply circuit of the motherboard is damaged, causing the independent graphics card to be unable to supply power after being plugged in, and naturally cannot be identified.
Possible reasons: 1. The accessory power supply of the graphics card is not connected or is not in good contact. Please check the accessory power supply. 2. The graphics card has poor contact. It is recommended to shut down the computer and wipe the gold finger before reinstalling it. 3. The power of the power supply is not enough. Please confirm whether the power supply is sufficient. 4. The graphics card itself or equipment other than the graphics card is defective. It is recommended to change the platform or contact the dealer for confirmation.
, if the motherboard does not have an integrated graphics card and the monitor does not light up after installing the independent graphics card, it means that the video signal output by the graphics card is not received. Check the contact of the graphics card and reinsert it. If it does not work, try replacing the graphics card. 3. Check whether the graphics card has an independent power supply and whether the power supply is connected properly.
The main reasons why the black screen does not light up after the graphics card driver is installed are as follows: The driver version is incompatible. The latest driver version may be incompatible with the system or current hardware, causing a black screen. You can try to download an older compatible driver and install it. System files are corrupted.
If the above does not solve the problem, consider that the independent graphics card is not compatible with the motherboard. You can go to the motherboard's official website to see which types of graphics cards the motherboard can support, and then change the graphics card according to the model. Finally, the signal wiring needs to be checked. The monitor side and the independent graphics card side must have the same type of interface at both ends.
Possible reasons: 1. The accessory power supply of the graphics card is not connected or is not in good contact. Please check the accessory power supply. 2. The graphics card has poor contact. It is recommended to shut down the computer and wipe the gold finger before reinstalling it. 3. The power of the power supply is not enough. Please confirm whether the power supply is sufficient. 4. The graphics card itself or equipment other than the graphics card is defective. It is recommended to change the platform or contact the dealer for confirmation.
Check to see if the graphics card is fully inserted into the PCI slot of the motherboard; check whether the power interface is connected and whether the light can be lit; re-plug the signal cable output from the monitor and graphics card or Replace the wire; check the power supply to see if the power consumption is sufficient.
The monitor suddenly goes black; sometimes the computer starts normally, but then a black screen appears when it reaches a certain step. A black screen is caused by the monitor itself not working properly, such as a problem with the monitor's power cord, poor contact with the power plug (note: both ends are possible), a broken power switch, a fault in the internal circuit of the monitor, etc.
1. The computer does not respond when I turn it on, and the monitor is black, but the fan turns on. When I turn on the computer, the fan turns on, and the monitor does not respond. , and there is no alarm sound, there must be a problem with the computer hardware. It is best to use the replacement method to eliminate the problem. Judgment method: Press the uppercase and lowercase switch key on the keyboard.
2. When the computer is turned on, the fan only spins and the monitor does not respond. There must be a problem with the computer hardware. It is best to use the replacement method to eliminate the problem. Judgment method: \x0d\x0a Press the uppercase and lowercase switch key on the keyboard. When the light comes on, it indicates a fault with the graphics card, monitor, or other hardware.
3. According to your description, there may be the following situations: The CPU cooler is installed incorrectly, causing the CPU to not work properly. Please check whether the CPU cooler is installed correctly, making sure it is firmly connected to the CPU and the cooler's fan is working properly. Improper power connections to the motherboard may result in the power not being able to properly supply power to various components.
The above is the detailed content of The graphics card won't spin and the monitor won't display.. For more information, please follow other related articles on the PHP Chinese website!
