Ah, so one chip for digital that can feed one display and another chip for analog. Kinda what I was figuring. > What are you using for video? X?

In either case, I still think it needs to be able to drive that much display. Not sure why the proprietary driver can and the Free Software driver can't. 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780L [Radeon HD 3000] (prog-if 00 [VGA controller]) Subsystem: Micro-Star International Co., Ltd.
