Ok, I found out how to change your video resolution to anything you want using regedit. I reccomend you back up your registry before tweaking it. Also, don't Go over your video cards min/max resolution.

1. Navigate to:
HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\{Address of primary video card}\0000\

2. Find 'DefaultSettings.XResolution'. That is your y axis. Edit as a Decimal to what you want it to be. IE 1152.

2. Find 'DefaultSettings.YResolution'. That is your x axis. Edit as a deciaml to waht you want it to be. IE 863.

3. Restart, and your done.

Note from forum admin: This tweak may or may not work for everyone for the resolution you want.
