LG 34UM95 Monitor Review
by Chris Heinonen on June 18, 2014 7:00 AM ESTAll measurements are done using CalMAN 5.3 from SpectraCal and a custom workflow. An i1Pro and C6 meters are used to measure accurate colors and low light levels. For all test patterns I use APL 50% when possible to prevent backlight tricks and other things from skewing the results. Full field test patterns are used with the display uniformity testing.
With the backlight set to minimum the LG 34UM95 puts out 55 cd/m2 of light. That is a good number that is low enough to work for any dark environment, but not so low that you can’t use it. The brightness control operates in 1% steps giving you lots of room for adjustment. The maximum light level is 270 cd/m2. This is a bit lower than I would like to see, as direct sunlight will still wash things out, but it is decent. Most people likely will pick a setting in the middle of these and the brightness adjustment makes it easy to get the level you want.
Black levels are also very good. The minimum black level achieved is 0.0586 cd/m2 and the maximum level is 0.2724 cd/m2. The 21:9 monitors have been very good so far at getting low black levels and the 34UM95 is no exception.
These combine to give us a contrast ratio very close to 1,000:1. As this is now what I consider to be acceptable in a good IPS display, the LG 34UM95 does not disappoint.
So far, so good for the 34UM95. Let's move on to the color accuracy.

The graph on the top of page 6: "Processing Lag Comparison (by FPS)" and then you have the units on the graph in terms of ms. At a quick glance, it looks like there is 18 FPS of lag which would be ridiculous.inighthawki - Wednesday, June 18, 2014 - link
The only thing ridiculous about it is that it makes no sense because FPS is not a measurement of time, it's a rate.ERJ - Wednesday, June 18, 2014 - link
Dang'it...we've been waiting a month for these to come back into stock (except for the price gougers) and you posting a review is not going to help the situation :)Gambit2K - Wednesday, June 18, 2014 - link
I ordered one this morning to replace my three 23" 1080P NEC screens. Bought them for Eyefinity and have used eyefinity once in 3 years :)RagnarKon - Wednesday, June 18, 2014 - link
Bought three Dell 23" screens for the same purpose. Used Eyefinity four times, and then stopped using it. Now I'm down to two monitors (rarely used the third).BUT, I can get behind this 21:9 monitor. Not ready to order yet though, price too high.

Unless I'm mistaken, this monitor comes with Thunderbolt 2, and not Thunderbolt 1 - do you know if it'll still work alright on an older Mac with only Thunderbolt 1 though?mackjam - Wednesday, June 18, 2014 - link
I was wondering the same thing. According to this form it does work. http://arstechnica.com/civis/viewtopic.php?f=19&am...crazysurfanz - Wednesday, June 18, 2014 - link
thanks for that link, lots of good information there.DrKlahn - Wednesday, June 18, 2014 - link
I bought a Dell 21:9 (1080) last year. My work machine has 3 1080 monitors, but I don't have the desk space to replicate that at home. This lets me see about a monitor and a half when remotely controlling my work PC. Which is a big improvement. The extra width makes it feel somewhat like a 3 monitor setup. The resolution isn't crazy, so it's not hard for the video card to drive while gaming. Editing video on it is great. The extra width gives you a lot more room to play with timelines. The vertical resolution is no more constraining than a normal 16:9 1080p monitor. Of course the extra resolution of this monitor would only make it better. Just wanted to chime in on using a monitor with this aspect ratio in the real world.cknobman - Wednesday, June 18, 2014 - link
Now just get the price down below $600 and I'll be interested.
