I have this computer that I’m repairing that used to have a display problem. It would work fine with VGA but when DP was connected it would flash rgb and white and black. I did a factory reset and reinstalled drivers and it seemed to work fine till i unplugged VGA and now the display connected via DP flickers on and off. What can i do?
Okay. The VGA works fine when it is hooked up by itself. The flickering happens when I disconnect VGA when i have both VGA and DP connected. When DP is connected by itself it has that flickering problem but if i connect the VGA as well and run dual monitors like that there is no problem.
I don’t have much specs on the computer as it is a computer I found. All I can say is that it’s an HP ProDesk 500GB 180W that’s probably not too old maybe 3 years and looks new and fairly in good standing
