I just upgraded to a Sony STR-DH820 (my first receiver with HDMI) and am having some odd video scaling issues. I have a computer running Windows Media Center hooked up to the receiver by HDMI, with video going out to a Sony widescreen TV also hooked up via HDMI. Unfortunately the video from the computer looks to be scaled up about 120%. If I connect the computer directly to the TV there are no scaling issues. (The computer's display is set to 1920x1080). I also have a blu-ray player hooked up, and it displays perfectly fine. Anyone got any suggestions? I can't find any settings for the receiver that would seem to affect video scaling.
