i have a very old Vizio Gallevia 42"...the first 1080p one they had.

http://store.vizio.com/gv42lfhdtv10a.html

I have my PC connected via HDMI (radeon 5850 on win 7 pro)

TV wants to say 720p is "native" but will read 1080p just fine. Reading in the manual...it seems RGB connection COULD read 1080p native but I guess it doesn't matter...pc's in 2006-2007 were not using HDMI.

The V+H Position had to be adjusted to fill the overlay gaps on the screen. There were even bigger gaps before I had ATI Catalyst set "Overscan" to 0.

------------
Question: Is it possible my screen flickers because it doesnt read PC input very well via HDMI?
Could there be a problem between the version differences of HDMI on my 5850 and HDMI on my TV?
Would RGB be a downgrade?

Screen flickering seemed worse when my 2nd monitor (my actual pc monitor) went into sleep mode. Flickering still seen even without my 2nd monitor connected.

Thanks!

The screen is flickering on LCDs is usually due to the refresh rate being set too low.

fixed it, it liked the YC:4:2:2 ratio much better

looks great now, especially with a brighter backlight setting :)
