Very poor quality HDMI output to HDTV

Question

Very poor quality HDMI output to HDTV

I recently decided to switch from an Apple TV to Mac Mini for my media center.

I have an Insignia HDTV and the quality from the Apple TV was outstanding. When I plug the Mac Mini in, however, it is EXTREMELY poor. The picture appears blocky & pixelated.

Any suggestions on how to fix this?

Mac Mini 2.4ghz, Mac OS X (10.6.5)

Have you tried adjusting the resolution in System Preferences/Displays?

It's set to 1080p which, from what i understand, is what should be used when connected via HDMI.

I did adjust it, but nothing seemed to make the quality any better.

Kyle, Have you found a resolution? I have the same results with a Mini and a Insignia 23" LED display. It appears by reading other messages here is the problem is with the Mini's HDMI and most HDTV sets not just Insignia. I have been trying to resolve for a week with no luck.

UPDATE: My problem seemed to be with the overscan feature of the Insignia panel. The option was "greyed out" and would not allow disabling. I switched to a 23" Samsung panel and it works fine. I am now using the Insignia as a secondary display.
