I recently connected gtx580 to my 2k monitor with hdmi, but windows default shows 2560x1080 is te max resolution. I use nvidia panel to create custom resolution 2560x1440, then it worked but everything looks fuzzy and not as sharp as I expected. So is it cossible to connect gpu with monitor by two hdmi cables to increase bandwith in order to get crisp textures??
