When I do a "gop list", I get:

mode 0: 1024x768x32, stride=1024
mode 1: 640x480x32, stride=640
mode 2: 800x600x32, stride=800
mode 3: 1366x768x32, stride=1376

So first off, that's weird that whatever "stride" is lines up 100% to
the horizontal resolution in modes 0,1 and 2 but not mode 3 (which
appears to be the default).

Is there a way to change the default mode by putting something in
loader.conf do you know?

Thanks again for your help!
