Brian, what kind of input did you use to connect it to your computer? Component, VGA, or HDMI? Did you experiment with the TV overscan settings that are documented in the manual? (I'm looking at the PDF manual that was posted here a few weeks ago and it mentions pitch, phase, H/V center settings, display area, etc.)
I'm particularly interested in this because I'm looking for something to connect to my HTPC, which I use for about 99% of TV viewing. It would be great if I could get 1:1 pixel mapping with this set, or something close to it.
