I've got one of the new 23" Apple Cinema Displays running on a Sapphire 9800 AIW Pro and unfortunately it will not display anything at all when booting my PC. The display does however work once Win XP has loaded. From the Apple forums it appears that some cards display all the boot info whilst others don't, depending on manufacturer, chipset, etc. Mine is unfortunately one that doesn't whilst others have reported that their 9800's (non AIW) work perfectly fine. What is causing this? Some people are pointing the finger at Apple for using non compliant DVI timings or whatever, but I can say with 100% certainty in my case that once Win XP drivers are loaded the display is fine so something must be incompatible with the 9800 AIW's BIOS that the Apple doesn't like when booting. Can anyone shed further light or perhaps think of a fix?
