Computer monitors often have some malfunctions, so do you know that there are black lines on the computer monitor? Let me briefly introduce to you the black lines on the computer monitor. The reasons and solutions! I hope it can help you!

Solution 1 for black lines on the computer monitor:

You can press F8 to enter the advanced mode when you turn on the computer.

In the "Advanced Mode" interface, select "Safe Mode". After entering safe mode, go to the Settings Manager to uninstall the old driver of the display card, and then restart the computer to enter the normal system. , and try to update the display card driver again.

If you cannot successfully update the display card driver in safe mode, you need to enable the "Driver Signing" function. The startup method is My Computer-gt; Properties-gt; Hardware->Select the "Driver Signing" button.

Open the driver signature options window, select "Warning - Prompt each time you select an operation", and then click OK. The subsequent operations are the same as above, first uninstall the old driver, and then update again Just the graphics card driver.

Solution 2 for black lines on computer monitors:

First, let’s eliminate the problem of the VGA cable. Remove the monitor's VGA cable and replace it with a new one. If a similar situation still occurs, it means there is a problem in other aspects, proving that the cable has been eliminated. So here I also put together a picture for you to see what this line looks like.

That excludes the problem of lines, then we can only look at the problem of the graphics card. First of all, don't be too nervous when disassembling the graphics card, otherwise it will easily cause damage to the graphics card. We first turn off the power supply and open the chassis. The graphics card is locked with a screw. We first remove it so that it can be replaced. If it means that there is no big problem with the graphics card, but the screen still has wires, then we can only judge the problem with the monitor. Here I have also compiled a picture of the graphics card for you.

Here, we can only prepare one monitor and replace it to see if there is any effect. First, disconnect the VGA cable from the previous monitor, and then replace it with the existing monitor. If it turns on normally, it means there was a problem with the previous monitor, and it needs to be repaired. ?
