This is urgent and direct question to ATI support team
I have one thinkpad T61 upgraded to windows X recently. Unfortunately, my ati mobility graphic card has been found as the microsoft basic display card by windows X which means the maximum resolution is 1024X768 only. This is no change after installation of ati catalyst driving tools. But no such compatibility issue from another T60 which has intel made graphic card.
This is so annoying experience on new windows. don't what's the alternative solution to given an advanced display mode by windows. Does this undetectable problem root from old BIOS incompatibility? Need hints from ati support team to find out a solution before I have to roll back to windows 7.
