T42, ATI Mob. Radeon 9600/9700 cannot run 1280*1024 in Vista

Hey Thinkpads friends

My ATI Mobility Radeon 9600/9700 serie in my T42, cannot run 1280*1024 after I've upgraded to Vista (a clean installation of Vista). I'm using the latest driver, however "ATI" doesn't seem to have fixed the problem yet. Any of you got a solution?

First of all: your thinkpad will run either 1400x1050 or 1024x768 according to it original design.

It does not look good when using an alternate resolution.

Mine works good with the same ATI Mobility Radeon 9600, with vista drives, lenovo's drivers and catalyst.

The problem is, that it can't run a resolution higher than 1024*768.

I think you need 128MB of VideoRAM for 1280. I have a T41p and I can use this Resolution without problems(On an external TFT of course). Maybe you could turn of Aero Glass, because then you wouldn't need that much VideoRAM

I should have written it, but I do not even get the opportunity to choose a resolution above 1024*768 - it's the highest resolution available...
