Samsung SM 757DFX + Rad X1600Pro

[Guest]

I have Samsung SyncMaster 757DFX and ATi Radeon X1600Pro. I have a problem
with refresh rates - I cannot set the res. of 1152x864x32 with 100Hz refresh
rate though my monitor and gfx both support it and I can use this settings in
XP without problems. Vista (Home Premium 64bit) behaves as if it couldn't
detect the 100Hz mode. 85Hz is the highest available choice. This is the only
problem that stops me from upgrading XP to Vista

What can I do? I'm loosing my eyes

Are you using the RTM release since it contains a later version of the
NVIDIA drivers then the release that is available from the NVIDIA Website?

I don't have nVidia gfx but ATi Radeon. nVidia drivers won't help me much.

I'm sorry I must have been responding to the wrong post. I assume that you
are using the "RTM" drivers from the ATI Website. I have however read of
several users having trouble with displays with Vista X64. I assume you are
running WinUpdate fairly regularly to see if new drivers are available since
they very likely will show up there before they show up on the ATI Website
since ATI will probably want to make sure that they are on the WHQL and are
signed before they post them.

All correct but I have some clues. I just reinstalled WinXP and realized that
I have similar problem here unless I install OmegaDrivers (those based on
Catalyst 6.9), then install official Catalyst 6.11 a finally uninstall
OmegaDrivers. After that "workaround" all works fine on WinXP. I think this
may be the same problem on Vista, I'll check it later when I have some time.
