Hi - I very recently bought the Dell u2414h for my PS4. There's plenty of reviews online but in short I've found it absolutely fantastic so far.
Two things that set it apart from other IPS panels for me is:
1) Audio out - so can pass the sound through the hdmi & monitor and out to stereo to plug into your speakers.
2) Number of outputs - 2 x HDMI, 1 x 1.2 DisplayPort & 1 x MiniDP. So don't have to fiddle around changing etc
It also comes factory calibrated which is pretty cool for a monitor around the £200 mark.
Cheers,
