When I try to change the resolution to 1680x1050 (a common resolution for widescreen monitors) using the 'SetResolution' command, I get the following:
[list:28m5dqrb]
SetResolution 1680 1050 16
Failed to set resolution 1600x1050x16
Restoring to previous resolution 640x480x16
[/list:u:28m5dqrb]
Note that is says "1600" instead of 1680 for some reason.
Out of the two other 16:10 resolutions I tried, 1280x800 didn't work but 1440x900 did. All the 4:3 resolutions I tried worked fine.
