Resolution problem on my Dell Latitude D810

[Christophe]

I have a Latitude D810 with an ATI X600 and a native screen resolution at
1920x1200.

Vista propose me only 1600x1200 and not more ??

When I install the ATI's driver beta for Vista, it will be ok but each time
I start Vista, my screen resolution come back to 1600x1200. I can right
click on ATI icon near the clock and select 1920x1200, it works but Vista
can't save my setting. Each time, it come back to 1600x1200. I don't
understand why ?

Can you help me ?

Thanks a lot for your help

This may work, maybe it will not:

Try turning UAC off, rebooting, set the resolution you prefer, rebooting and
see if it stays the same.

The UAC is already off. The problem is I can't choose my native resolution
1920x1600.
The maximum Vista propose me is 1600x1200.
I would like to choose more but how ?

Thanks for your help

I have that same problem, only I had 1920x1200 running with the ATI Radeon
drivers for Vista for almost 2 weeks and after the long weekend returned to
work and now 1600x1200 is the highest I can get. I've tried removing the ATI
drivers and reinstalling them but I get the same thing. I don't believe I
installed any recent updates either. Very odd.
