help with VX2265WM

[bouxdag]

Hi , I can't get my VX2265WM to display 120 hertz when connected to my laptop. The user manual says a 'dual link DVI video card' is required for 120hz, but I have a 8800M GTX, and according to NVIDIA's site it should be dual link as best I can tell... http://www.nvidia.com/object/geforce_8800m_tech_specs.html

When I connect the monitor to my older desktop PC with an ATI card, I have no problems. On my laptop, I have tried reinstalling the monitor driver numerous times, and I've tried many different versions of NVIDIA drivers and refresh rate forcing programs for windows. I've also tried setting a 'custom resolution' of 1680x1050 with 120hz timing in nvidia control panel, but it shows 4 smaller screens with visual artifacts and such when I do.

FYI, I'm also running 32 bit Vista on my desktop and 64 bit Vista on my laptop. I'm setting windows to 'use only one monitor' in nvidia control panel as well but the only options I ever get for monitor hertz are 59, 60, and 100. When I uncheck show modes only safe for this monitor or whatever nothing new is given.

Does anyone have any ideas on how I can fix this...or is it even possible? Is there some reason my laptop can't output 120hz at 1680x1050? Any help would be so greatly appreciated.

maybe the dvi output on your laptop isn't dual link? Which driver are you using on your laptop, I always found it best to use a hacked version of the latest desktop driver.

From the wikipedia entry for DVI:

Are both the socket and the cord using the middle two columns of pins? That is to say, using 24 pins instead of 18?

Edit: wow, that picture linked funny. The top one is DVI-I (single link), the second is DVI-I (Dual Link), the third one is DVI-D (single link), the fourth one is DVI-D (Dual Link), and the last one is DVI-A.

The socket on my laptop looks like the picture of the DVI-I dual link picture above. I assume this is because it's compatible with both DVI-I and DVI-D dual link. It looks the same on my desktop which can run the monitor at 120hz. The cable and the monitor both look like the DVI-D dual link picture.

My laptop is a Sager 5792, which from everywhere I can find any information about it, should support dual link DVI...
