My Mitsubishi DLP overscans the image sent by the HTPC, causing the taskbar and other controls to fall off the screen making them inaccessible. There is no way to defeat this overscan that I know of.
The obvious/common solution is to create a custom desktop resolution in the nVidia driver, but this creates non 1:1 mapping when playing HD content. madVR confirms it's scaling the image to the desktop resolution. (94%)
Automatic resolution switching sounds like a good solution, but my testing with it showed it didn't return to the desktop resolution all the time, so wasn't a great solution. It's quite possible I wasn't doing it right.
What else could be done to reconcile this issue?
I'm going thru a Yamaha AVR, which may or may not contribute to the issue.
