Monitor wont go to 75 hz at supported resolution

[zipify]

I recently got a new monitor ( http://www.newegg.com/Product/Product.aspx?Item=N82E16824116656 ) Here is a list of the resolutions and refreshrates that the monitor supports i got right out of the manual: http://i.gyazo.com/c582191e918c3351ae78499823a230a5.png

I am trying to get 1400x1050 at 75 hz but it seems to only be allowing me to be at 60 hz.
The highest resolution I got to work at 75hz is 1280x1024

I am using a DVI cable and my graphics card is a 6950.

If you need any more information just say so and any help is appreciated.

Well, first off, you really should only be running at max resolution all the time anyways: 1920x1080 @ 60hz for your monitor. Any other resolution will not look as good, especially in normal desktop use. You can scale the DPI higher, if some things are a little too small for you, but it's generally best to only use the max resolution on LCDs.

Anyways, to answer your question
* Download the monitor drivers and see if it lets you use the higher refresh rate after you install them: http://www.viewsonic.com/us/vx2252mh.html
* If that doesn't work, maybe there is a way to force the refresh rate and resolution in the ATI control panel.

It is for gaming purposes (I play competitive CS:GO)

This is how monitors typically work. They may support 75hz, but not above 720p typically. At their native resolution, they are 60hz.
