is 1680/1050 only 60 Hertz ??

I got my new monitor yesterday, a Samsung T220. When i play games i always put Vertical Sync ON ( i cant stand the horizontal tearing effect when SYNC is OFF).

So, this monitor have a refresh rate of 75 hertz, when i play in 1280/1024 sync ON, max FPS is 75, but when i display in 1680/1050 Sync ON, max fps is only 60. . .

So, is it normal a 1680/1050 resolution only support 60 hertz ?? Is there any way i can set it to 75 hertz ??

Thx !!

60 Hz is the standard for LCDs. This can been translated as saying that your monitor updates 60 times per second, which is more than enough considering movies are filmed at 24 FPS, TV at 30, and that the human eye can't detect much difference above 34-36 unless you have amazing eyes. For people that say they can tell the difference, its not that you see the higher framerate...its that your eyes percieve an increased smoothness due to texture processing speeds. In other words, some games even at 60 FPS can seem "jerky" or "sheary" while a game at 40 FPS can seem smooth. V-SYNC forces your framerate to cap at your max refresh which removes tearing.
