560M with Cinema Display help
I have an Asus G74SX laptop running Windows 8.1, and an Nvidia GTX 560M with driver 327.23 (it runs color grading programs better). I also have an Apple 30" Cinema Display. I'm trying to get my Cinema Display to work with laptop. I have the display hooked up to a HDMI to DVI adapter into my laptop. It comes up native 1280x800, but I want to get the 2560x1600 working. I know the monitor doesn't display 1920x1080. I customize the resolution in the Nvidia Control Panel to match these settings http://www.3dexpress.de/displayconfigx/timings.html . I just can't change the horizontal refresh rate and pixel clock, but they are close enough. The custom setting isn't working at all. Is there something I can do, or is this just not possible at all? Do I go VGA out?

Thanks.
