Booting Ubuntu 9.04 RC iso image. I see nothing on the screen until I get to the logon window, to get there I had to use key combinations from I knew from booting on another PC to go through boot screen prompts. Once booted up the screen resolution is so unusable that I can not make adjustments. I believe this problem is due to an unusual hardware setup. This consists of an RCA HDTV rear projection TV using DVI input from an ATI Radeon 9250 graphics card. I believe Ubuntu is picking the wrong graphic port or screen resoution on the card at boot. Please note that I have not tested other Ubuntu ISO images previous to this attempt.

Here are the properties of the card (From Windows XP)
