If you get a Dell display, figure on getting an XRite i1 Display Pro profiling tool at the very least. Dell's photography oriented displays will show 10 bit color which is nice if you use Photoshop or any other application that supports a wide-gamut, 10 bit display pipeline, but you'll need the correct version of software to be able to internally program the display for proper calibration.

Don't make the mistake of buying a $300 display because so-and-so uses it and loves it. There is a very big difference between editing on a properly profiled IPS or GB-LED 10 bit wide gamut display, and a #300 gaming monitor that is likely TN and changes color each time you move your head to a new angle. The entry level Dell Ultrasharp monitors will get you pretty close to the $1500+ professional displays. The cheap Samsung is a far cry.

Here is an article that details the process of proper profiling for the Ultrasharp displays:

Bottom line, gamut and color consistency across the screen should be your deciding factors. Resolution? Not so much. FWIW, I use a pair of Dell 2413s because I like a wide workspace. The end result is a screen that is 3800x1200 in resolution, and text that is easily readable. Text scaling on hi-res displays is imperfect at best.

While I concur with the numerous recommendations for IPS, there's one item that has not been addressed, and that's the screen ratio. Most hi-def monitors sold today are in the 16x9 format to mimic what a HD TV has. So, if your primary thing is to watch movies on the computer, that's the format you should choose. However, some, like me, never use the computer to watch movies, so I have always opted for the 16x10 screen ratio. That gives a slightly higher dimension to your computer usage. It's just a personal preference. Locating a 16x10 is hard to find....ASUS has their ProArt series, which has 16x10. Good luck!

Mine is an IPS monitor (LG) and it's great. It can be viewed from any angle and still show a clear pic...

IPS monitors or “In-Plane Switching” monitors,
IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.
