Make sure the power cord and monitor cable are securely connected to the computer and monitor.
Try replacing the power cord or monitor cable.

Shut down and unplug the monitor's power cord.
Wait 60 seconds, then plug the power cord back in and turn it on.

Open the case and check whether the graphics card is correctly inserted into the motherboard slot.
If the graphics card is loose, unplug it and reinsert it.

Outdated graphics driver may cause display problems.
Please visit the graphics card manufacturer's website to download and install the latest driver.
