All 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.

White Level -  i1Pro and C6

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.

Black Level - 1iPro and C6

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.

    "... Oculus Rift and 4:3 ..."

    4:3 in nowhere in Oculus Rift spec. Each eye is fed with square image; actually the vertical dimension is slightly larger than horizontal one(!).

    Occulus Rift should still have widescreen displays - our vision is much, MUCH wider than it is high.

    well that's funny you say that since this is pretty close to have 2 x 4:3 monitors.. side by side lol

    Only people with eyes prefer wide screen.
  • Marthisdil - Wednesday, June 18, 2014 - link

    It is a niche market. The market for $1000 monitors is relatively small right now.

    In screens maybe, in other things no. EG there isn't even a Korean camera company worth mentioning. Even Samsung just plays way behind while Japan dominates still consumer cameras and the US and Germany have the only two pro movie camera companies anyone actually buys.

    If it was 2160p and half the price i would totally buy it,as it is now ... i want it but i know better than to not go at least 4k at this point in time.
    Anyway,good to see the 29 incher getting a bigger brother.

    2160 vertical with 21:9 will make it 5040/2160. That's even higher than 4K you are expecting for half the price

    They're making them as 2.37:1 5120x2160 displays, perfect for watching scope movies. Right now there are only a few large (80"+) models in the wild, but I'm hoping we'll see these so-called 5K displays work their way down to desktop size.

    I'd much rather have a 5k display in 5120x2880 at ~30", 16:9 in that size would play nicer with my existing multi-monitor setup and the resolution would give 2:1 scaling options for software that isn't hDPI aware.
