Resolution reverts on new monitor

[nameon]

Well basicly ive been using a small 16" monitor for almost 6 moths @ RESOLUTION of 1280 x1024 and all was peachy unitl i plugged in my new samsung syncmaster p2450, 24" you see when im in windows i can change the resolution upto 1920x1080 but the problem is whenever i reboot, when at windows login screen it starts at that resolution for only a second then automaticly reverts to 1280x1024 , im using the latest possible drivers of the monitor(installed after the problem started),
got latest catalyst 11.8 and all win7 updates installed but this problem sticks

System specs
sapphire Amd radeon hd 6950 2gb
win7 64bit
asus crosshair iv formula motherboard
amd phenom ii x4 970 be 3.5ghz processor

what could be the problem? drivers?, windows? catalyst? faulty monitor?

Any help would be appreciated

That's a strange one, it might help to uninstall all the drivers first, reverting back to basic vga, and then reinstall the card and monitor drivers.

its just the matter of resolution, i log in, apply 1920x1080,
reboot, windows loading screen and the 1st second of windows login screen are in 1920x1080, then screen blacks out for a second and comes back with 1280x1024, what could it be , is it remembering my old resolution?, could driver reinstall(windows reinstall) fix it, to me it looks like a process that starts takes over at login screen, could it be a faulty monitor,

You don't seem to have read MagicPants' reply. This is almost definitely a driver issue, regardless of if it's "just a matter of resolution".
