LG 34UM95 Monitor Review
by Chris Heinonen on June 18, 2014 7:00 AM ESTPre-calibration I used the Warm color temperature preset and the Gamma 1 setting. This provided results closest to our targets of 200 cd/m2, sRGB color gamut, and a gamma of 2.2. The RGB balance is good overall and the largest issue is the gamma. Yellow and Green are slightly over-saturated but most of the color gamut is good overall.
| Pre-Calibration |
Post-Calibration, 200 cd/m^2 |
Post-Calibration, 80 cd/m^2 |
|
| White Level (cd/m^2) | 207.8 | 198.8 | 81.3 |
| Black Level (cd/m^2) | 0.2023 | 0.205 | 0.085 |
| Contrast Ratio | 1027:1 | 970:1 | 955:1 |
| Gamma (Average) | 1.98 | 2.20 | 2.37 |
| Color Temperature | 6791K | 6511K | 6494K |
| Grayscale dE2000 | 1.65 | 0.46 | 0.81 |
| Color Checker dE2000 | 2.08 | 1.30 | 1.34 |
| Saturations dE2000 | 2.84 | 1.15 | 1.20 |
Post-calibration the RGB Balance is nearly perfect and the gamma is ideal as well. Color errors are improved due to the more accurate gamma but the 100% yellow and green colors are still overly saturated. Our contrast ratio drops slightly but is still good. With our 80 cd/m2 target and sRGB gamma the 100% issues at Green and Yellow remain but other colors are much better.
With a white LED backlight system, the LG is limited to the sRGB gamut. Using the internal color management system you can correct the over-saturation in the yellow and green colors but I would advise against it. I did this and while 100% improved, every saturation below 100% is worse and and the color checker test is worse as well. It is nice of LG to include a CMS system, but it does not function correctly in my testing. I would much rather see a multi-point white balance, which does work correctly, to help correct for the RGB balance and gamma inside the display instead of in the video card LUT.
Post-calibration the LG 34UM95 is good but not excellent. For most people it should be just fine, but for graphics professionals the extra saturation will pose a problem. LG also provides their own calibration software but I was unable to get it to run correctly on my MacBook Pro or PC. Even when it detected the display correctly it is unable to use my i1Pro or i1DisplayPro meters to calibrate itself. Assuming this performs similar to my last experience using it, CalMAN will still provide superior results as the LG display lacks an internal LUT.

Thoughts on moving from using two 24" 1920 x 1200 monitors to this one? I'll lose some horizontal pixels and pick up some vertical. Used mainly for video and audio editing.scottrichardson - Thursday, July 3, 2014 - link
SeanFL, I'm in the same boat as you. Running two Apple LED 24" Cinema displays but one is about to die. Apple doesn't sell a replacement display compatible with my 2009 Mac Pro, so I'm looking at this LG. The extra vertical resolution will be nice, and possibly more useful in many cases for my design/coding work.Wondering if there are any further updates on the backlight bleed issues?

Scott, I picked one of these up a few days ago and am very impressed. No backlight issues that I can detect, and the display is beautiful. A much nicer display than the Dell Ultrasharp 2407. Not having a bezel in the middle of my workspace has also been an upgrade. Haven't missed any of the vertical pixels that I gave up when setting aside two 1920 x 1200 monitors.Now I'm looking for a mount to be able to switch between sitting and standing. The
Ergotron LX seems like a nice fit.

correction, make that horizontal pixels I gave up. btw, mine was manufactured June 2014, mentions rev02 on the back.scottrichardson - Monday, July 21, 2014 - link
That's great news Sean. I have mine ordered through my local computer store. They were told there's a 'worldwide shortage' and are not expected to hit the country until after the end of July. I don't mind waiting. Apple ended up replacing the panel in my 5 year old 24" LED display for FREE, which was very nice of them (after how much I paid for my Mac Pro setup, they felt it was fair!!!). Really looking forward to the display for the same reasons you are enjoying yours. No bezel in the middle, extra vertical pixels etc.inperfectdarkness - Wednesday, July 9, 2014 - link
Never! There shouldn't even be 22/9 screens. We need more 16:10 screens. Screw hollywood's ridiculous widescreen formats.gochichi - Thursday, July 31, 2014 - link
You're so right about this. Just to think about how simple the connection would be at this point to a 2560x1600 screen. I have no clue why 2560x1600 is stuck at a 30" display option and no other option. I would love to see 2560x1600 at 20", 23", 25", 27" etc. It would so awesome, and finding a computer or laptop with a DisplayPort is all that would be required. We can dream...gochichi - Saturday, July 26, 2014 - link
This technology segment has had a true lapse in innovation in very many years. So much so, that these obvious products finally coming is more than welcome. And if I have to bite my tongue and call it "innovation" then I will.I think that companies assume that people don't have decent eyesight way too much.
Where is the obvious 23" 2560x1440? Where is it? Where in this stagnant,-no-good market is such a product? We have 11" laptops with 2560x1440... but no 20" or 23" desktop monitors?
Well, I got tired of waiting, so I got the UP2414Q which is really fantastic. So much less dorky looking than the 27" displays. But it won't run flawlessly on every machine.
Here's the difference between stupid reality, and the wonderful non-innovation that should really be: I WILL buy an $800-$1000 display for myself, but if the market weren't so retarded... I'd buy 70 units of 23" 2560x1440 IPS displays (with DisplayPort and HDMI) for $500 a pop. I'd buy 70 units, if not more.
So this whole market is stagnant from sheer greed and this imaginary notion that nobody cares, where the reality is that anybody with a 2010+ MacBook (Air or Pro) would love nothing more than to plug into a 23" "retina" display for that price.
Example of devices that run 2560x1440 flawlessly, but 4K at only 30Hz
Surface Pro, X1 Carbon, MacBooks,
Just to be completely clear, I would, and so many others would too... prefer to spend $500 on a 23" instead of the 27" units available for years now.
I'm so disgusted with this market... sure this particular product is less stale than most, just like my Dell UP2414Q is also less stale. But why not have a vibrant product that everyone could enjoy? Why are they pretending that there's a niche market when the reality is that there's a massive, unaddressed market of people who want nice, and need practical. Of people that need other things on their desks other than a screen. Of people who have money but don't want to waste it on junk.

Thanks for the review. It's a tempting proposition when looking at the screen, but taking everything into account I find that $999 is too much money for what I'd get. I'll stay with a 29 inch 21:9 instead, and I'll get some daylight on my desk as well....GerardFreeman - Tuesday, September 16, 2014 - link
Can some one tell me what GPU will run this monitor at full res?
