I get a green vertical line on the right side on my monitor. It is an Acer X233H and the line is on all the time. During bios, windows and even when the computer is off and the monitor doesn't have a signal. Monitor issue or is there something that I'm missing. I checked the connections and everything is fine. I just replaced my 600w ps with a 750w because the 600w burnt out. Thanks for the help guys.
Before you RMA the monitor, verify that both ends of your video cable are securely fastened (with both the monitor and PC powered off). If both ends are screwed on tight and you have the same issue, then RMA it. Good luck!
