Info - Gfx Card: 7850 TV: Element 55 inch OS: windows 7 64 bit

I'm using 1080p/HDMI.

When I turn my computer on, I get 'no signal' all the way until the log in screen, because apparently the BIOS/start up routine isn't being displayed in 1080p, but that doesn't seem right. When I first got my computer, I had no problem setting stuff up in the BIOS screen.

Now, when I start my computer from being 'asleep', it constantly flashes to 'no signal' for about 5 minutes and then it stops and never does it again the entire time I'm using it (until I put it to sleep again).

Does anyone know what could be causing this? I feel like my TV might have faulty HDMI ports, but I'm not sure. When I play games, any time the resolution goes below 1920x1080, I get 'no signal'. Some example of games: The Sims 3 and Wizardry Online. I can't even play them and the only way I can get my display back is to Alt+Tab until I'm on my desktop.

Have you checked the cables or tried different ones? – Brad Patton Feb 15 '13 at 15:20

Try uninstalling/reinstalling ATI drivers from

There's often a BIOS option for selecting a default display adapter. May want to make sure that is set correctly along with the various power settings.

oops, fixed it. – Enigma Feb 17 '13 at 0:28

Perhaps you have blown capacitors in your monitor. Flashing screens can be a symptom of that. I would recommend you try software fixes before opening up your monitor though.
