I've been using my HDTV as my monitor via a DVI-HDMI cable and it's been working great.

However today when I booted up my PC, there was no display on my TV, it just said 'No Signal'.
So I plugged the cables out and in, restarted the computer and switched on the TV. Now I'm getting 'Not Supported'. The TV just won't display anything, I only have the audio from my speakers.

This has happened before and I just mess with the cables a bit to fix it, but nothing seems to work.

Before this problem, I was having those red flickering artifacts on my desktop. Maybe that might have something to do with it, so I'm going to try ordering a new DVI to HDMI cable and hope that'll fix it.

Also, I use the TV for my PS3 as well, if that makes a difference. I just switch back and forth between PC and PS3

Anyone know what the problem is? Any help is much appreciated.

Specs:
Radeon XFX 7870
600w PSU
i5 3570k
and Hannspree TV

I have a HDMI to HDMI cable but that doesn't seem to work either. I also tried hooking by laptop up by HDMI to HDMI and that too didn't work.

Do you have another monitor lying around anywhere? Maybe a friend's? This might be a problem with the TV.
