LG 34UM95 Monitor Review
by Chris Heinonen on June 18, 2014 7:00 AM ESTAnother area where 21:9 displays have shined is in their uniformity. They have had some of the most uniform screens of anything I have tested to date. The LG 34UM95 proves to be a good performer here, but with a couple issues.
As soon as we look at white uniformity we see what the issue is going to be. The upper corners of the display are very dim in comparison to the rest of the screen. If you leave those corners out the rest of the display is very uniform with an all-white screen. The middle 60% of the display is within 3% and even the lower-corners are within 5%. It's those upper corners that are dim that cause a problem with the uniformity.
Black Uniformity is also good except for a bit of brightness in the lower-right corner. The upper corners are darker, which isn’t as much of an issue with black as compared to white. The lower-right corner has a significant rise in black level but very little change in white level. Excluding that point the rest of the display is quite good.
Other than the lower-right corner, the whole display has a contrast ratio of close to 1000:1 with a median of 979:1. The average is dragged down by the lower-right corner as you’d expect but overall the whole screen is good here.
Color Uniformity suffers as a result of the dim corners at the top of the screen. This causes all the color checker samples to miss their target luminance levels and dE2000 errors are higher as a result. As you can see in the center of the screen, uniformity is excellent, but those corners are just not good. The Median color error is only 1.27 but the average falls to 1.65 due to the poor performance in the corners. If you are doing photo work, you can use the center of the screen and be safe, which is basically a 27” display at that point, but avoid the edges due to the light issue.
It is a shame the two upper corners on the LG are so dim. Had they been closer to the rest of the display it would be an excellent performer for uniformity. As it is it only comes in as a very good display. The uniform area is still close to a full 27” QHD display in size, but that is making an excuse for those two corners.

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?
