I have a D600 that is docked to a D/APR. Running Win2k SP4. It is equipped with Radeon 9000 mobile graphics.
I have tried updating system BIOS, setting BIOS to boot to the Systems graphics card, updated all display drivers (latest CATALYST from ATI), updated all laptop system drivers (NSS update from DELL) and even tried a mod utility I found in the Dell message boards that supposedly should have addressed this problem (DHmodtool3).
Still no luck. When I go to look at my display properties, it tells me that I am using "(Multiple Monitors) on ATI MOBILITY RADEON 9000, but I only have one monitor icon above that. I am expecting to see two numbered screens but cannot for the life of me get it to work that way.
I have tried using both the digital and analog outputs on the APR. Any other thoughts?
