Anyway...
I have a Sager NP8170/Clevo P170HM laptop which I am trying to connect an Asus VG236H 3D monitor. My GPU is the ATI 6990M which should be capable of running 120Hz in 2D. I am not interested in 3D.
However, when I hook up using the monitor supplied Dual Link DVI cable my video card (in either the control panel or the Catalyst Center) does not show any 120Hz options. The best I am able to select is 1920 x 1080 @ 60Hz. The monitor only accepts a 3D signal (hence the 120Hz refresh rate) over the DVI and not the HDMI 1.4 input.
I do not know what I may be missing. Any help with this is appreciated.
-------------------------------------------------
Resolution Refresh Rate
Horizontal Frequency
1680x1050 60Hz 64.674/65.29kHz
1920x1080 60Hz 66.587/67.5kHz
1920x1080* (DVI) 100Hz 113.3 kHz(2D)/113.8KHz(3D)
1920x1080* (DVI) 110Hz 125.1 kHz(2D)/125.7KHz(3D)
1920x1080* (DVI) 120Hz 137.2 kHz(2D/3D)
Note: You must select one of the * timings for enabling 3D feature with a compatible NVIDIA-GPU graphics card via Dual-link DVI cable connection.

Does this mean from the monitor manual that my ATI card won't work with my Asus monitor?

I have an update...
After talking to people at 2 different companies and getting bounced around, I finally call only 1 of 2 people in the country that actually know about how this GPU is utilized. For some reason while the 6990M is capable of rendering 3D on its own laptop screen the GPU is NOT connected to fully use the dual link DVI rear output port. So 60Hz at 1920 x 1080 is the best it will do over EITHER the DVI or HDMI ports.
It was unfortunate that NONE of the resellers of this GPU understood this important piece of info and mislead everyone that chose this GPU over the 580M thinking it was capable of exactly the same output as the 580M.
