Problem is I am getting 2048 x 1536 no porob let alone 1920x1200.... Just for giggles ran up to bestbuy and got another dual dvi cable for $70, same results wont hit 2560 x 1600... I see it flash on and off repeatedly and then just reverts back to the 2048 x 1536 res....ive tried adjusting the refresh but it only shows 60hz on everything except 1280x800 and that has 59 hz??? Im seriously bummed at this cant seem to figure it out? Ive tried it alone on my 4870x2 alone on a 285gtx with both no matter which way I do it it maxed at the 2048?? I seen a DVI to HDMI cable maybe I could try that port ?
