My 37" Westy's DVI-2 does not support 1080p either, only DVI-1 (and
VGA). And I'm using a single-link DVI cable for 1080p w/o any problems.

It'll run w/software opengl rendering if hardware opengl isn't working,
but it looks like you have hardware opengl there. So like Brad says,
make sure you're using the OpenGL painter.
