This article will explain in detail how to solve the problem of no signal on computer monitors in windows. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Some friends must have been to such a problem, as soon as the computer is turned on, the monitor shows no signal, the host should run normally, the fan is turning, and the connection cable has been re-plugged. Why at this time? Next we will introduce the solution to the lack of signal on the computer monitor. I hope it can be helpful to you.

Computer monitor no signal analysis answer:

1. Now the best way is to hang the memory, cpu, and hard drive on another motherboard to see if there is something wrong with your motherboard.

two。 The display shows no signal, which means that the display is powered on, and you say that the host is running normally, although the hardware has been judged to be bad, it is recommended that you still cut off the power of the display and the host, and then take off the connection cable between the display and the host and reconnect it. Pay attention to see if the pointer of the connection cable of the monitor is damaged.

3. It's probably the problem with the graphics card. I don't know if your video card is integrated or independent, then wipe the gold finger of the video card with an eraser.

4. Try to turn off the mainboard battery and discharge the mainboard battery, and clean up the memory if the golden finger is unique.

5. If you are sure that the monitor has been powered on and high voltage is generated, continue to check whether the data cable connector of the monitor is in good contact with the signal output interface of the video card. Is it loose? Unplug again and check to see if there are any bent or broken pins or a lot of dirt in the D-connector. This is a problem often encountered by many users. When connecting the D-type socket, the force is uneven, or forget to tighten the fixed screw of the interface, so that the interface is loose, resulting in poor contact, or due to improper installation or excessive force, there are broken needles or bent needles in the D-type interface, resulting in poor contact.

6. Open the chassis to check that the monitor card is installed correctly? Is there good contact with the motherboard slot? Does the video card or slot accumulate too much dust because it has been used for too long, resulting in poor contact? Whether the chip on the video card is charred or cracked. When the black screen is caused by the video card, the computer has a short and four-long "tick" sound when it powers on self-test. When installing the display card, hold the upper part of the display card with your hand and insert it into the slot uniformly, so that the fixed screw mouth of the display card coincides with that of the main chassis. Do not forcibly fix it when it is not plugged in, causing the graphics card to distort. If you confirm that the installation is correct, you can remove the video card and wipe the gold finger of the pin with an alcohol tampon or install it in a different slot (for PCI video cards only). If not, you can only change a good graphics card to have a try.

On the windows computer display no signal solution is how to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
