One of the computers in my household (call it computer A) randomly stopped outputting a signal to its monitor (monitor A) this morning, even though it was working last night before it was shut down. Monitor A's dispay is still working because it shows a "no signal" message. Monitor A is VGA and was connected to computer A's DVI port with an VGA/DVI adapter.
After checking connections and power, I unplugged a working monitor (monitor B, which is a TV) from my own PC (PC B), which uses an HDMI port, and plugged it into PC A's HDMI port for testing. I'm not 100% positive that PC A is capable of outputting an HDMI signal but I thought it was worth a try. Monitor B also didn't get a signal from PC A, so I reconnected monitor B to PC B's HDMI port.
But now monitor B isn't getting a signal from PC B either. I've cycled the signal source on the TV's menu (display is still working, just not getting a signal), restarted PC B with and without the monitor B plugged in, and powered everything off and unplugged it all. I've also tried connecting monitor A to PC B (by way of PC B's DVI port) to make sure PC B didn't decide to ouput to DVI for some reason, but monitor A is also not getting a signal.
I can't see the computers' menus to fiddle with any settings, and I'm at a loss. I couldn't find any forum posts from users with exactly the same problem. Any ideas on something else I can try?
