Input Lag is still measured using the Leo Bodnar lag tester at 1080p. The LG supports 1:1 scaling modes as well as aspect and wide. In all these modes I had the exact same results so whatever scaler LG is using for this is very quick. If you run a game at native resolution or scaled you will likely see similar results.

Processing Lag Comparison (By FPS)

I measure lag at a scant 18ms. For almost all gamers this should be fast enough, and with the extra wide view you’ll potentially see more of the environment when playing games. Of course, this is dependent on the game, and some games will simply crop the top and bottom rather than expanding your field of view.

Gamutvision reports that 73% of the AdobeRGB gamut is covered by the LG 34UM95. This is right by the 99% of sRGB coverage that LG specifies for the display, and what you should expect with White LEDs and an IPS panel.

LCD Color Gamut

The power draw is comparable to a 27" LCD despite the larger size of the LG monitor. Even with a USB hub and Thunderbolt ports, the power draw is good here considering the size and resolution.

    Why doesn't this have any of the input ports on the side? Whenever I want to slip in a flash drive I want an easily accessible port.

    Given the width of this monitor, I suspect most users would actually find it easier to reach the ports in back.
    The ports aren't too densely packed, so once you acclimated yourself to the location, the back ports are probably pretty easy to access by feel.

    5120x2160 would be amazing - once you get that you'd probably wont need to buy another display again

    Everything is fine except the price. When will the price of monitors greater than 24'' come down!

    Based on this model I would like to:
    Remove Thunderbolt, USB und audio to make it cheaper.
    Make it a bit smaller (27 - 29") but keep the resolution.
    Add variable refresh rate for stutter-free movies and games.

    At this point I'd be willing to spend 500€ on it even though I'm pretty pleased with my current model.

    Wow those pictures are grainy.

    I really like this monitor. I currently have a Dell U2711 at 1440 x 2560 and would love a little more horizontal real estate to play with. 4K is just too much screen and does not scale well currently.
    It is a niche product but IMO way overpriced at the moment. I would consider an upgrade to this monitor if it was priced at a more reasonable $800 or less... Part of the cost is most likely due to the non standard IPS panel size. Still having an IPS panel with these dimensions is a great idea, certainly for the way I use my PC...

    Some really misinformed replies in the comments section..

    "It's niche but it's not for enthusiasts" ?
    - Enthusiasts are a niche market as they are a minority.

    "The Human eye is actually 4:3"
    - lol

    "4K is the future but 21:9 is not" ?
    - Err so what about a 21:9 4k display ? Not so much ? Fine I'll take one.

    "more people want 4:3 than widescreen"
    - WTF ?

    Ever since the 21:9 ratio was released in displays people whom have gone out of thier way to find ways of shunning it. Perhaps because they are trying to justify everything where they have spent thier moneies and is the only way the can react to not being able to buy the latest and greatest??

    21:9 is finally here,thankgod, and its here to stay, so get used to it.

    My thoughts on the physical aspects of the display...
    It seems like they have got a lot right here, but I cant stand plastic silver finish. I really don't like materials that are cheaper knock offs made to look like something they're not.

    Also these un even sized bezels, they should be equally thin on all four sides. NEC was the only company to do this right imo.

    Also...

    Make it black or make it with high quality materials like Apple do, or even better do both.

    Bet the panel itself is very impressive though.

    I like 21:9 but not the initial panels that had a horizontal resolution of 1080. This panel has a more usable 1440.....

    "21:9 is finally here,thankgod, and its here to stay, so get used to it."

    Fine. Turn this monitor to portrait mode and be happy. Excuse me if some of us wan't IMAX experience, not embrasure world view.
