OK Solved problem.. It was the monitor drivers fault... I did install drivers for monitor but i didnt restart bc windows didnt ask and i dont restart my computer so often

... but after the restart i get to chose all possibles resoulutions

... Also my frend have same problem with LG monitor and when installed drivers (any eaven drivers for xp work on the cd you get with the monitor) his resoultions are back to normal... ) ...
So if anybody ahve similar problems it is 99% a monitors fault... and yes restart your computer after installing the drivers for monitor

...
Cheers!
