That's a symptom of many issues.

Take a Volt meter to the CMOS battery and if it's the common CR2032 it must be over 3 Volts.

Next, research BAD CAPS.

Finally since there are no make, models here, that's also a sign of an overtaxed power supply.

It's a shame details are missing as it could be one of the common issues but without details, you have to check these and more.

use a known good monitor

See if it's the other monitors with the problem, or the computer. That gets half the job done.
