Update: I got a dvi to hdmi cable for wally world, same thing no display over 640x480, so I call westinghouse, they told me to unplug it and plug it back in, WHY do all trouble/help lines tell you to do this, has never worked for me on anything ever. So it didn't work and he said probably bad boards and a bunch of stuff not communicating, go replace it, so I am 2 hours from nearest costco, so I start experimenting and find out that only HDMI 4 works and only if you set your computer on 1920 X 1080 at 60hz before you hook it to the tv, so now I have a picture thats about an inch short of the edges. But its working sort of!!!!
So I go to switch resolutions to 1920X1200 and its not in the list on my ATI drivers, but the set is recognized as a westinghouse now at least, the guy on the phone said 1920x1200 was native resolution but the manual says set at 1920x1080? I found a button on the remote it has normal, which displays an inch or so black around the desktop area, fill, which is close but cuts off a little around the edges, like only 1/4 of the windows start icon is still showing and half the text on boxes on bottom bar, also an ovescan setting which zooms in and loses a lot.
am I happy, not sure yet, I'll wait and see what the real tech that takes 24 hours to call me says, I'll use it for now and post how I like it later, picture is as nice, almost as clear as the 37 inch westinghouse, but letters are a little blurry on this one......or maybe its my old eyes lol, put on my glass's and pretty nice picture and text
