Pros: 4k @ 30mhz (Displayport 1.1a) looks great...very nice for graphic design/photo editing

Cons: 4k @ 60mhz (Displayport 1.2) probably looks awesome if it worked

Overall Review: There is a huge issue with this monitor. Asus and Sharp comparable monitors had the same issue but put out a user enabled firmware flash to fix it. Dell refuses to acknowledge their monitor has any issues. The problem is that when you enable Displayport 1.2, you only get 1/2 of the screen to show up...and sometimes nothing at all. I know my pcs and there is nothing wrong with my hardware...it is without a doubt, the monitor. Googling for 2 days to see if I could find a fix left me unsatisfied but I at least found out, I'm not the only one. Hundreds of these monitors have the same issue...as a matter of fact, I didn't read a single webpage that someone reported that their monitor actually worked with no problems. For a $2500 monitor, it's not worth [email protected] could by a 60" TV and get that resolution. I want [email protected] it right dell. Fix your junk.
