What People Are Saying

Rated 5 out of 5 by from Helps my productivity I am using this for audio mixing and editing and occasionally using dual control with 2 computers. It saves me from having to juggle about with windows all the time and it helps me with file transfer. I am very happy with it and can recommend it to anyone doing video or audio editing.

Rated 5 out of 5 by from Amazing monitor First impressions, whooa - the sheer size of the thing. Initially I thought that it was way too big, but had it just over a week now and getting accustomed to it. Having the dual / three / four screen facility is superb and it really is just like having extra monitors but without the frames in the way. Some web pages cannot cope with the extreme size, they do their best, but one can reduce the scaling which helps a bit. I opened Excel and got 42 columns without re sizing! As expected games are fantastic (if they support the ratio of course - even if they don't it's still pretty good) The split screen facility even works on remote desktop connections which is nice.. Best bit - the utter surprise on friends' faces when they see such a screen.. It's lovely.. nice one LG...

Rated 3 out of 5 by from Too expensive Beautiful screen. 0 bad pixels. No backlight bleed. Excellent viewing angles. Much too expensive for the features. You can buy two 27" 1440p monitors for the same price (at least in my region). I chose this monitor because I hate bezels. This might be the last monitor I ever buy. If the upcoming VR craze lives up to the hype.

Rated 5 out of 5 by from A beautiful screen This monitor is very crisp (despite having a lower resolution than its big brother LG34um95. The colour is very good and I have no dead pixels . I do wish that the stand had more height adjustments.
