I have two monitors (monitor 1 and 2). Both were working fine. I left my computer running, and after a couple of hours went back to my computer. Monitor 1 (my primary display) would light up but there was no picture. I rebooted, tried another spare boot HD, but still no picture, not even during boot up. I switched my monitors so that monitor 2 is now my primary display and monitor 1 is my secondary display. Monitor 2 works fine, but still no picture on monitor 1. It lights up, just no picture.
It appears to me that the problem is with the monitor, and not any other hardware problem. It’s an inexpensive Acer that is a few years old, so I can easily replace it. Before doing so, I thought I’d ask here to see if anyone has any other recommendation.
