HEADLINE: Try using the DisplayPort cable that shipped with it.
I got the new Dell U3011 Monitor today – 30” monitor capable of up to 2560×1600 resolution. It ships with three cables – DVI (Dual Link), VGA, and DisplayPort. The DVI is attached and all the instructions show that you can use the 2560×1600 resolution with the DVI… but I couldn’t get it to work.
After about an hour talking to Lance at Dell he suggested trying the DisplayPort cable and viola – I now get 2560×1600!
I use a 55” monitor with 1920×1080 resolution at work. With that I can see 38 lines of code in Visual Studio. Here I can see 62 lines of code! That’s actually going to make my 55” monitor look small now.
I hope this helps other that might be having problems. I saw lots of posts, but no solutions. It seems that for some reason the feedback loop from the monitor to the computer isn’t working with the dual link DVI cables so it doesn’t think the resolution can be higher, but DisplayPort works fine.
