Chris, Wow. Reading your message gives me a sense of how little I know about foam cutting.

You can find some information on fixing video resolution here: https://help.ubuntu.com/community/FixVideoResolutionHowto almost any advice for ubuntu will apply here, with the caveat that accelerated graphics drivers (particularly the proprietary ones) often kill real-time performance. Be sure to re-run the latency test after any change in your video configuration.
