Here is a review - I did not write it...but found these comments on the web:
http://www.newegg.com/Product/Product.aspx?Item=N82E16824025007Pros:
(a) Color reproduction is one of the most accurate I've seen on 4k
(b) Thin bezels!
(c) Extra wide panel is nice to have for editing
(d) Solid metal stand that isn't bulky
(e) A good response time and minimal ghosting for a 4k IPS panel
(f) Good contrast
(g) Perfect white levels
Cons:
(a) Some slight color shifting left to right
(b) There is some back light bleed. But unless you are looking at a black screen in the pitch dark, you won't notice it.
(c) Stand has no swivel
(d) A single button for using the monitor settings, does not work well
(e) Can only modify Kelvin in intervals of 500K... should be able to have much more granularity
(f) Included color correction software is bugged and unusable
(g) Very poor black levels, but this is common for IPS
Other Thoughts: I've been waiting for a good 4k monitor for years. Only now have we finally come into line with the combination of this monitor and recent updates to Windows 8.1. The LG 31MU97 is a solid monitor. But far from perfect. A little bit about my background: I work as a professional designer and programmer, and the CEO of a software development company. I spend most of my time designing UIs in the sRGB color spectrum, programming, or editing photography in Adobe RGB. I also spend a good amount of time on After Effects doing motion graphics. I do put these monitors through their paces up to 20 hours a day, and I like my screens to be flawless. I have used the Samsung UD970, the Dell 24" 4k, 32" 4k, and their 27" 5k. The iMac retina, non retina, and thunderbolt displays. All of the professional offerings from NEC and Eizo. PA328Q, Pro Arts, PBs, Acer's 4k, the TN based 4k panels. I've really used just about every 4k panel there is, and a huge amount of the great 1440p panels out there for professional use.
I'm the kind of person that will run a color calibration suite on 3 different calibrators 6 times each. I'm that OCD about my monitors
This one beats them all, but it's far from perfect. In my opinion, it's the best 4k monitor you can buy right now. I hope that changes, and some day we can enter monitor nirvana with the perfect monitor that does everything we want perfectly. But until that day, this will be my monitor of choice. The most disappointing part of this monitor is the slight color shifting on the left and right sides. It starts to get a little bit red. It can get frustrating at times. But until there is something better (all 4k monitors color shift a ton and this probably has the least of all, it's just very persistent) this is the one I will use for work that isn't super critical (I'll be sticking with my NEC PA272W for anything that needs to be exactly perfect, although I do love the 4k, until they get a little more accurate we will still need our good ol 1440p)
