If you don't have a video card with DP port, you may have to buy a converter that may cost you $50;The minimum version of DV port it supports is 1.2.You may got a bad DP cable which happened to me

I ended up purchasing a cheap DisplayPort cable that worked worlds better.

The panel on the back that protects the cables is a bit hard to put into place, or open.

I do wish that the multiple ports on the back of the monitor were better positioned as they are facing down as opposed to facing out and can be a bit of a pain to get the cables inserted as opposed to ports that face the back.

However, after I accidentally broke the cable and had to buy a new one I realized the included cable was the issue as the new cable functions perfectly

Finally it points to the wrong cable.

Happy with monitorTook the place of two 21" monitors, fewer cables to mess with

after reading a lot of reviews I ended up buying an LG monitor (34UC80-B) that has the same panel as the Dell new model but cheaper

Other than that, I see some tearing issues that either A) could be the video card... although the GTX 980 shouldn't really have those issues or B
