Is AVR set to upconvert, or pass original format?
When you set it to 1024x768, is the desktop clear?
When you set it to 1024x768, press INFO on your Tv remote. Does it report that the Tv is getting a 1024x768 signal?
Older Tv's don't have a 1920x1080 panel, yours might have 1024 x 768. In theory you want to match your PC resolution to the panel pixels. The problem is, usually Tv's can only do that on the "PC" input, not hdmi. If the Tv can accept 1024x768 on hdmi and the AVR will pass that to the Tv then that is exactly what you want. If your Tv can only do 720p or 1080i on HDMI, you really want to send 1280x720p or 1920x1080i and let the AVR pass the original format so the Tv will scale it to the native panel pixels just like it does for any other video device. If you do that and the desktop looks bad then it's likely because of the low quality Tv scaling to native panel pixels.
After you get the desktop resolution figured out. Run WMC goto Settings > TV > Configure your TV or Monitor > run through the wizard and set the video format to the same as your desktop. If you set it to anything else then every time your run WMC it will over ride the desktop resolution, that's the "recalibrating" you are seeing.
