What people are saying

Rated 5 out of 5 by from Great high tier monitor This monitor is fantastic. I recently bought all three panel types to get a first hand comparison of them all. They were a 240 hz acer TN panel, 120 hz ultrawide viotek VA panel and this screen. I can’t feel the difference between 240 and 144 hz. The VA panel is just too big for competitive gaming.This IPS panel is by far my favorite. It sits at a good price for the features and quality, while still being good enough for having that competitive edge.

Rated 5 out of 5 by from Fantastic Monitor! For many years I have been using a TN panel for competitive gaming, and a 2nd more color accurate monitor for editing videos and photos. This monitor is not only a combination of the two, but looks even better than both! My concern was that the 1ms that is advertised is actually unusable due to overshoot, when using the faster setting. I use the fast setting which is advertised as 5ms, and don't notice a difference than my 1ms tn panel. The truth is most panels (even tn) that say they are 1ms truly are not. If you look at benchmarks comparing this to other tn panels, it actually has the same response time, if not very slightly slower. As far as the colors for this monitor goes, I honestly didn't realize how much games would look different than my tn panel. It looks like I put all of my games on a higher graphics setting, as everything is much more clear. I have not done editing with this monitor, so I can't speak for that, but I have watched a couple videos in 2k and was blown away. As far is the back lighting uniformity goes, it is hard to say if I got lucky or LG's quality control is much better than other manufactures, as I don't see how the uniformity could be anymore perfect. I honestly can't tell where the backlight is coming from which was a concern of mine, with buying the monitor off amazon. I also am going to post this review on other websites, as I have seen comments from other people wondering how good this monitor actually is. So if you see it on other websites with different account names, its not because LG payed me. I purchased this monitor with my own money from Amazon, as I needed an upgrade.

Rated 5 out of 5 by from Excellent Gaming Monitor! Best monitor I've ever owned. Bought this primarily for gaming, and couldn't be happier. Playing games at 1440p 144hz is really incredible and silky smooth, and the quick response time is excellent. The only negative thing I can say about this monitor is that is has pretty bad IPS Glow, which is quite noticeable in dark scenes. If that doesn't bother you than buy this monitor if you can.
