You maybe have 3rd party program for REFRESH RATES in games like REFORCE, RADEON CATALYST CONTROL CENTER,...
You must revert original settings meaning all games have 60HZ refresh rate by deafult.
If that doesn't work go to:
X:\Battlefield2\mods\BF2\Settings\VIDEODEAFULT.C ON - open this file with notepad and change line renderer.allowAllRefreshRates 0 to 1 like this renderer.allowAllRefreshRates 1 save and exit.
It should work !
You owe me a beer !

just kidding
LET ME KNOW IF IT WORKS !!
YOU TWO GUYS HELPING DON'T KNOW NOTHING !! YOU ARE JUST NOOBies
