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.

So is every other corporate grade monitor. My 24" Dreamcolor Display cost $2000 a few years ago.marcosears - Thursday, October 9, 2014 - link
I agree. Most people will want to get one of the top monitors at a more reasonable price range. /Marco from http://www.consumertop.com/best-monitor-guide/evilspoons - Wednesday, June 18, 2014 - link
I don't understand the attraction some people have to 4:3 monitors. Human vision is naturally "widescreen" and looking up and down is much less comfortable than looking left and right. Natural selection 'trained' us to look along the horizon, not up and down. Our retina may be 4:3, but it's not like a single monitor encompasses our entire field of view... now, talk about selecting an LCD panel for a VR display like the Oculus Rift and 4:3 will have my complete support...DanNeely - Wednesday, June 18, 2014 - link
For anything text related, wider lines are harder to read; so making the screen wider doesn't bring a benefit; but wider screens tend to be shorter meaning that fewer lines of text can be shown at a time.bigboxes - Wednesday, June 18, 2014 - link
I have a 16:10 monitor, but I don't run MS Word or my browser at full screen. I size the windows ~4:3. I have room to move things around and watch video in widescreen. I think that 21:9 @1440 is great. Two full size windows on one screen instead of two 20" monitors with a bezel between them. It's niche, but not for enthusiasts.TegiriNenashi - Wednesday, June 18, 2014 - link
"Human vision is naturally "widescreen" "That widescreen propaganda is wrong, human vision is close to 4:3:

Short screens are ridiculous waste of pixels on the sides.

Here is verbatim quote: "The approximate field of view of an individual human eye is 95° away from the nose, 75° downward, 60° toward the nose, and 60° upward"Let's do arithmetic, shall we? (95+95)/(75+60)=1.4Let me put it this way. Humans have 2 (two) eyes. Each eyeball is round. Even if both eyes vision didn't overlap, the maximally wide FOV covered by two eyes would be two adjacent squares. Which makes the aspect ratio to 2:1 max. However, non-overlapping view this is extreme scenario, more applicable to lower species (such as fish).
To summarize, 2.35:1 is ridiculous invention from previous century. The framing of most scenes in movies is awkward, with actors top of the forehead chopped off. Hollywood should kill it once and for all.

No, human vision is not "naturally widescreen". It isn't just the retina alone that determines field of view, and normal field of view is 4:3. Also, I don't know why you would have more trouble looking up and down than side to side - I certainly don't.Your comment about "natural selection" - you are just making that up. Personally, I'm a big fan of watching where I put my feet, that doesn't involve looking at the horizon. I think that's pretty much normal, but maybe I'm wrong.
You are confusing societal conditioning with the fundamental man. If you lived in a different kind of society, one that hunted animals in trees, for example, your conditioning would be entirely different, and you wouldn't think "wide-screen" was so "natural" because it would be "natural" for you to look above you as much as to the side. Movies are made wide-screen because of the limitations of seating arrangements for audiences more than anything else. There are scenes in which that view works well - like looking at a horizon with an unobstructed view, say from the deck of a ship or a mountain top, but there are areas where the wide screen utterly fails, as in the experience of walking down a city street between tall buildings.
Movies largely turn us into floating entities without feet living in a sky-less world. It isn't natural, we are just conditioned to it.

I may be betraying my age, but on my 30" 2560x1600 display + 24" 1920x1200 display set up, it is much easier for me to look at the bottom half of the display than the top half, and in fact, I prefer moving my head sideways a greater distance (towards the 24" display) than tilting it up. If it's just for a few seconds then it's not a big deal, but for longer periods of time, my body definitely has a preference.Also, I'm not sure field of view is the relevant thing to measure. Even if I were to only use a 24" or a 20" display, I am not trying to see the entire display as a whole, but a specific area at a time, so length:width ratio of the display is not significant. Length:width ratio of the window I am focusing on is far more significant, especially in terms of readability of text. Watching videos full screen or playing games would be a different matter, of course.
I suspect for my scenario/working habits, a wider display (which allows moving less frequently-used windows off to the side) would be preferable to a taller but narrower display, requiring me to tilt my head more often (or waste real estate), as well as to having a dual-display set up as in my current one.

I seconds this, although with "just" one 16:9 or 16:10 monitor. I tend to put things I focus on at about the same height, independnet of how much space is left above and below it.
