Question PC & TV Connection

[johnbil]

I have my TV connected to my Desktop PC via an HDMI cable so that I can view videos on my TV. This setup has worked fine for years with no problems.

The TV no displays my PC output when I switch inputs (“No Signal Detected”). I have switched devices and the HDMI port works fine.

I have made no software changes recently.

The AMD Catalyst Control Center shows my PC and a second display as ‘Unknown’ (CRT, Analog, Disabled). I assume that’s the TV.

Anyone have an idea on how can I get things back on track?

That's an odd message. HDMI is digital, not analog.

Anywhoo, if you didn't do anything, changed anything, moved anything, swear and hope to die... I would run Windows Restore to a previous point when things worked.

Or maybe try to check if GPU or PSU is failing. This happened to me when my PSU is about to fail. VGA got no signal from PC to SmartTV.

Thanks for replying. I tried a System Restore, but it didn't work (didn't go back far enough, I guess). I'll look into the GPU/PSU approach.
