If its just flickering reduce the hertz to 60 and see if that works
Right click on desk top, then properties,then setting,advanced, monitor. there you should see screen refreshing rate. Set it at 60 hertz and see if it helps.
When it starts blacking out you will know because after about 1 minute when the computer turns on the monitor will blackout
I purchsed an HP system at Sam's clug several months ago. The monitor has had a flicker from the beginning, which is getting worse. I have tried everything in HP help and nothing seems to correct the problem. I have heard of the blackout problem. Is this the way this problem starts?
