A Review of the LG Electronics IPS Digital Cinema 31MU97 31.0-Inch Screen LED-Lit Monitor – 31MU97-B


When it comes to any sort of 4K display technologies, few companies can quite match the technical sophistication of LG and its manufacturing process. This doesn't apply any less to UHD monitors than it does to TVs like the cutting edge OLED models from...

Excellent refresh rate ; Comes with great 5W built-in speakers ; Excellent AdobeRGB color gamut performance ; Large 17:9 aspect ratio ; Full connectivity, including Mini DisplayPort ; IPS Panel brightness

Possible light bleed due to IPS ; expensive ; would be perfect with HDMI 2.0 port

The bottom line for the LG 31MU97-B is that you simply can’t go wrong with this monitor if you’re a professional in the video, visual and graphic editing fields. It’s also excellent for any normal use. Though you should be ready to spend a bit more...

Review: LG 31MU97 Digital Cinema 4K Monitor


4 K is an odd beast. There's no disputing that the resolution and clarity of images is absolutely beautiful and that once you get used to the sharpness it's hard to look at a 1080p monitor again but when it comes to everyday practicalities it's...

An exceptional monitor for graphics professionals.

Seems great, but some concerns


- I think this could really be a great monitor, but it will take a lot of additional work to get it running at peak potential, and they are really doing nothing to facilitate that process - Frankly its been emotionally stressful purchase and upgrade,...

- I love the extra screen size and crisp resolution, makes my second monitor seem fuzzy. I think it was a great move to step up to monitors in this class - adjustable monitor height is best I have seen. Smooth glide up and down

- NONE of the software installed correctly on my setup (Windows 10). It won't install directly from the CD, it throws errors continually, never worked, and eventually, i just uninstalled all of it. - There is a subtle flickering in the screen that...

I bough refurbished and had no trouble. All parts present and the screen looks new.

Hooked up to a Late 2013 Mac Pro base model using the supplied Mini DisplayPort to DisplayPort cable and it looks great.

No more computer volume control if you set the sound output to the monitor speakers using the DP cable. The speakers aren't great anyway (no low-end response but I'm comparing them to Boston Acoustics w/ sub). Also no more keyboard control of...

It Isn't Bad **Update** Returned it


I returned this screen after initially thinking I might be happy with the great deal I got even with dead pixels. The flashing pixels, broken mount parts, etc. just killed this monitor for me.

-Good quality 4k panel -Works well with my PC and a 780 GTX. ** Update ** Panel went bad after using it for a while. Had flashing dead pixels. I ended up buying a much more expensive monitor (Acer Predator XB321HK bmiphz 32-inch), and hope that will...

-Refurbished should just mean incomplete... I bought two, one was missing a small visually pleasing plastic shield that goes on the end of the stand to hide screws, and the other was missing an HDMI cable. -Doesn't work well with MacBook Pro, or at...

Love it, waiting to buy a second one


Windows 7 is ungraceful with DisplayPort compared to DVI. When the monitor turns off or the computer sleeps, DisplayPort signals that the monitor is off and Windows Plug-and-Play rearranges all windows to fit a default 800 x 600 desktop. Everything is...

Definitely the best monitor I have seen. Color and dynamic range are excellent out of the box, and profiling with a puck changed little. With DP, it runs full 4K resolution at 60 fps on GTX960, 970 and 980, even with a 10-foot DP cable. When NewEgg...

So far, none: no popping noises, cracking sounds, or black screen of monitor death. Maybe LG fixed those problems, but more likely it's a matter of luck. 'Hope my luck holds....

Buy a different monitor!!!



Nice picture when it isn't randomly going black.

Random loud popping noise even when muted with volume set to 0. Screen goes black for a second or two on some of the popping instances. Cable choices are limited. Need DP to mDP only. Factory cable is the only choice I have found. This monitor is the...

Great monitor - not working well with GTX 960 video card


Great color. Factory calibration made matching colors for my photo apps (lightroom/photoshop) very easy.

This monitor does not work well with a GTX 960 video card - black outs, lost lines, flickering. This behavior was not happenning all the time, but often enough to bother me. I switched the card with a GTX 970 - all of this seems to be gone. I will post...

Nice image quality


I paid $1600 for this thing and now it lists for about $1000. That plus the 300 more I have to spend to have it fixed make this a very painful subject. Don't buy it without an extended warranty.

Very clear sharp monitor

Three months after the warranty was up the monitor went dead. Newegg or LG refused to help. It's in the shop now, it will cost over $300 to fix.

Does not work well with GTX 960 video card


Bottom line great monitor but please do not use this with GTX 960 based cards. This is not a video card issue I have a Dell P2715Q works perfectly fine with both cards and all ports combination.

I like this monitor for its true 4K resolution, color rendition. On Windows 10 this runs with full resolution and on 60 Hz refresh rate on both GTX 970 and 960 cards, windows 10 scales very well. I am an amateur photographer and use Photoshop. This is...

I have 2 PCs one with GTX 970 based video card (ZOTAC GeForce GTX 970 ZT-90106-10P) and this monitor works perfectly but I have a second PC with GTX 960 based video card (EVGA GeForce GTX 960 04G-P4-3967-KR) where this exhibits random horizontal dark...
