I have two monitors hooked up to my computer. A 24" Samsung monitor running at 1080p, and a ~40"ish Hyundai TV running at 1024x768. Lowering the resolution on the TV does not help.
A while ago, the picture on the TV began to 'shake' seemingly out of nowhere, and then it turned off and displayed a 'No Signal' sign. I thought the cable was loose, because that's how it seemed to have acted.
The cable was not loose and after a few seconds it came back up. This happened a few more times until one time it didn't come back on.
The monitor is connected directly through a DVI connection. The TV is connected with a VGA cable to a VGA-DVI adapter, which is connected to the computer. The setup was working fine for a long time before it stopped.
The TV itself works fine. Other inputs work without issues (cable TV, gamecube, etc). The cable is fine, too. Connecting the same TV + cable to another PC works just great.
The videocard I'm using has two DVI ports at the back. The lower one does not recognize any VGA connections (through an adapter), so the TV has to be plugged into the upper one. I know that the upper port is working at least somewhat, because I can connect my monitor to it and it works.
The computer DOES recognize that the TV is plugged in. I am able to extend my displays and move my mouse over to the TV. It's just that I cannot see what's going on there because the TV only displays "No Signal."
Any help would be appreciated. I've done all I can think of and nothing works.
