What People Are Saying

Rated 3 out of 5 by from Works ok but not 100% iMac Pro compatible Works ok but not 100% iMac Pro compatible, the screen resolution is fine but when the monitor is connected the iMac mouse pointer is jerky intermittently. It's a real killer and every time the monitor starts I get the message "(Caution) make sure to use a supplied mini display port and HDMI cable" but the iMac pro doesn't have a display port but it on the iMac pro supported monitor list??? I tried a USB-C to Display port and the monitor is not even recognised. Very frustrating indeed. Apparently its a common problem on further research????

Rated 5 out of 5 by from LG won't disappoint Have had this tv for 5+ years. It's great, sleek and the picture quality and features are optimal for 2010. Consider this, all advanced features relevant to xbox one are compatible with this lg tv, even though the xbox was released years later. Lg products are competitively equal to other bands, and cheaper. They support all current generation features given the year of the product. I've never had a problem with my LGTV. It's served well and there has not needed to be any maintenance so far. The LG team knows quality as well as reasonable pricing on products.

Rated 4 out of 5 by from Almost Awesome it's now more than 6 months since i purchased the LG tv. it actually is far much better than my previous unit in terms of clarity and im spoilt for choice. i especially like the fact that the navigation is so simple yet precise. also the additional Bluetooth sound function is a plus. i however do have a couple of downside to it. the apps are limited (i wish they introduced KODI for this tv) also the storage is way way to small. i hope they introduce compatible 1tb disks that can be easily replaced, this will assist in strong downloaded movies and series to be viewed later and at leisure. this will also reduce the number of times that the apps have to stop in order for the tv to clear some space otherwise. i would highly recommend this to anyone.

Rated 1 out of 5 by from I bought this tv as a bedroom tv and didnt really use much. A month after 1 yr from purchase there is a problem with the lights in back of tv. It looks like 6 flashlights are shining in from the back of tv making the viewing experience terrible with too much white light to see anything. I called lg and the response i got was that it was no longer under warranty. I have purchased several lg tvs and other electronics and would consider myself a fan of the brand. I have since changed my thoughts and will be searching for a new brand to enjoy. No more lg loyalty from this consumer

Rated 3 out of 5 by from Does not work with 2016 Macbook Pro with USB-C Monitor is great looking. Problem is using a USB-C to DisplayPort cable. This will not work. LG emailed back saying they do not recommend using conversion cables, adapters or docks for this monitor but only the cables that come with the box. The displayport cable looks a little thicker than a standard displayport cable. So this will not work on a 2016 MacBook Pro. Will work with Apple Multimedia adapter with HDMI but at 30 hz. This is no ordinary 4k monitor. Bottom line go for the LG Ultra Fine 5K made for 2016 MacBook Pros. WOW that thing is amazing. Tried this monitor because LG 5k was not available yet at the time. Returned it and got the LG 5K. By new stuff with new stuff.

Rated 1 out of 5 by from Terrible - Buy a different monitor I bought this monitor over a year ago and had pops and blackouts that continued and got worse...using the supplied cable. I had it inspected twice and updated firmware at local repair shop. Finally had to send to LG for repair. It worked for a couple months but has just started to pop and blackout again. This must be a poor design, and completely ridiculous to have these issues with such an expensive monitor.

Rated 4 out of 5 by from Nice video quality poor controls The video is really nice and so are the extra inputs. The problem with it is you can't easily switch between inputs without navigating the menu which is really slow. There should be buttons for each input to make it faster. That is my biggest downgrade.

Rated 5 out of 5 by from only one issue... I believe this monitor should have the input. signal requirements documented in some more specific way. The flier "manual" sucks. I have purchased it, then returned it, as it kept going off on me, while in the highest resolution and over the mini DP, using supplied cable. I purchased another DP cable, with confirmed 4k specs, and the same issue was still occuring. randomly, after a few minutes, it was shutting off the picture, like it lost the signal. powering off and on was bringing the picture back, for another several minutes, then again... click... gone... I've then gone over the opinions about this monitor on the bestbuy site, and someone there said it turned out to be his gtx950 card. And that his problem was solved with upgrading to gtx970. I have ordered another monitor, and gtx970... I've then replaced my nvidia gtx950 with nvidia gtx970, and the issue magically disappeared. It's been working ok since. It would have been sooo nice to have some way knowing such thing when about to buy one. Not having to learn the hard way, going through the hassle of returning, purchasing another one... GTX950 isnt a bad graphics card. Its just not meant for playing some high grsphics games, and I don't play games. And the 950 does list the correct resolution/frequency in its specs. How could I have figured then, this is not going to work with 950? This should be better documented. p.s. I hate the joystick thing. super annoying.

Rated 5 out of 5 by from Amazing picture I have had this monitor for more than 6 months and I am still amazed how good the picture is. For games, videos or photos it is impressive how clear and sharp the images are.

Rated 5 out of 5 by from Excellent display I use this at work with the latest and greatest Retina Macbook Pro 15, and this is an external display which is worthy companion to the internal display. I also have 2013 rMBP but it is not capable of better resolution than 3840x2160 via HDMI and the image displays stretched. The colors look excellent and even colored surfaces look even. I use the monitor mainly for coding and use the resolution for desktop space, I run it at native resolution without HiDPI. The size of text becomes a very small even at this size (31 inches may sound large but it is not that large really, 40 inch would be better) and I am sitting very close to the display. The monitor can be viewed very close so it is not a problem, but it is excellent coding experience. I run terminal and Xcode side by side. I have increased font size on Xcode a little. I also use the monitor for 4K video editing (GH4, 1DX mark II) with Davinci Resolve and FCPX and for photo editing with Lightroom and Photoshop. The monitor is excellent in these tasks obviously. The DP1.2 output can not output continuously the 4096x2160 at 60 Hz, so to avoid monitor blacking out annoyingly, the output frequency had to be lowered to 50Hz using SwitchResX and it was not straightforward. With HDMI it is possible to use the monitor at 30Hz without such tweaking. This is not monitor's fault but Mac's fault and especially a serious limitation in OSX that it can not adapt to 50Hz without resorting to a third party app that "hacks" different frequency to the system. This is excellent monitor for those who know what to do (SwitchResX tweaking) and know the limitations of their computer and like with Mac can deal with them.

Rated 1 out of 5 by from Absolute Lemon This monitor is an absolute and total piece of garbage. It glitches. Blacks out. Wont turn back on. Ive tried new drivers and reboots. Everything. It has been a nightmare. Please do NOT buy this thing. Google the amount of people experiencing the same problems and you will see for yourself.

Rated 4 out of 5 by from Great image quality I love photography and video/photo composition. This monitor is perfect for this work. The only thing I do not like, is the control joystick. I have two PC and often switch the entry from one to another (the split screen is not good for me). to exchange input, I have to click with the joystick 9 times in various directions, I have other monitor where just one click. I hope in a new firmware to improve the function menu.

Rated 4 out of 5 by from Outstanding. Have had this for several months now and the colors and detail are outstanding. BUT, occasionally, when it is turned on for a period of time, there is a loud popping sound (like a capacitor discharging) and a momentary scrambling of the screen. Everything works fine afterwards and it does not seem to effect anything I am working on. I am worried because I do not know whether this is an indication of a potential major problem that will effect the life of the unit.

Rated 5 out of 5 by from Fantastic Monitor I have had the monitor about 2 months now and I couldn't be happier with it. The picture is amazing and I am surprised every time I sit down in front of it how good it looks. The features are good and it is easy to use and set up. It may be a professional grade monitor but you don't have to be a pro to appreciate how good this monitor looks. I am not much of a gamer but I have played a game or two on it and it is excellent for games as well.

Rated 5 out of 5 by from GOOD NEWS MACPRO 2013 USERS FULLY COMPATIBLE WITH MACPRO 2013. Forget about using your own cable, YOU MUST USE THE DISPLAY/THUNDERBOLT COMBO CABLE THAT COMES WITH THE MONITOR. I AM ABLE TO TO GET THE CINEMATIC DISPLAY MAX RESOLUTION 4096 X 2160 @ 60HZ VIA SwitchResX. EASY EASY SETTINGS. YOU MUST HAVE THE LATEST OSX YOSEMITE version 10.10.3 IN ORDER TO GET 60HZ WITH ProResX. So excited NOW. To all the VIDEO EDITING USERS, don't forget to calibrate your monitor. Don't let the near PERFECT pristine Graphic fool you. You'll get 2x the quality of your current graphic realism after calibration. Trust me. I DID NOT USE TRUE COLOR PRO, I instead used Spyder 4 Elite.

Rated 4 out of 5 by from True Color Pro won't start on OSX 10.10 LG please update your calibration software to be comatible with OSX 10.10 Everyone is using 10.10 and I get the "DDCI/USB communication may not be supported in this monitor" warning and everything is greyed out. So if your're aiming this monitor for professionals on the Mac side please update the software because we need to work on calibrated display!

Rated 4 out of 5 by from Initial impressions The LG IPS Digital Cinema Monitor 31MU97 looks very promising for use with my fully optioned12 Core late 2013 Mac Pro running FCP 10, Lightroom 5.6 and Photoshop CC. However it is not plug and play as the Mac display settings and LG's monitor options need to work together without fighting each other. Achieving 4096 x 2160 without linear distortion and having a Mac desktop of the same dimensions is the goal. I will try to make that work shortly and will update this review then as well as details on DCI calibration.

What monitor arm would I use with this monitor if I wanted to mount it on my desk?

Asked by: Freddy5825
The LG 31" Class 17:9 Digital Cinema 4K IPS LED Monitor (31" Diagonal), Model # 31MU97-B has a VESA Wall Mount Interface of 100 mm x 100 mm. That VESA Wall Mount Interface can be used for Wall Mount Brackets or Monitor Arms and it guarantees that if they are VESA Compliant, that they will fit provided they support the same Wall Mount Interface that the monitor has. So when you do a search for compatible desktop monitor arms, be sure to look for any that support that VESA Wall Mount Interface pattern...^IFV

The HDMI ports on this are version 1.4, not 2.0 correct? If so, can a 10 Bit color signal be transferred to this monitor using the unit's HDMI 1.4 port, coming from a Blackmagic Decklink card, which supports 10bit color export over HDMI (2.0)?
