Pre-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.

    "... 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
  • petergreyhill - Friday, June 20, 2014 - link

    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.
  • rituraj - Wednesday, June 18, 2014 - link

    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.
