Bumping a very old thread...but I was wondering if anyone knows of a solution to this problem? The M10000 board seems to have ALOT of issues with its resolution output.
I am having the exact same problem as the OP, except my video image is not being shown full screen on full reboots. Putting the computer in hibernation then resuming from it fixes the issue. But that is a temporary fix because the resolution messes up after a full reboot. I think the issue is due to the drivers because when I uninstall the S3 Unichrome drivers, everything works fine except I am unable to standby or hibernate. I tried disabling the S3 utilities from starting up with windows, but that didnt seem to do anything.
