I got a new MacBook Pro with Touchbar in late 2016 and treated myself to this display to accompany it. I loved everything about it - bright, vivid colors, crisp details, one-cable charging/output, easy menus. I decided to buy a second identical one two years later. I would have given it five stars until the second one arrived.
Unfortunately, the second one immediately had an issue with its coloring, with both displays set to factory default settings. I do not professionally edit photos or videos, but even simple tasks are distracting when the new display has an obvious yellow tint and the old one is a perfect white on web pages or documents.
Making matters worse, my new one is still under warranty, and I have now returned it to LG twice for repair or replacement. Both times, after going through the effort of shipping my monitor, being without it for two weeks each time, and reconnecting it two two different computers (a Dell Latitude from work as well as my MacBook Pro), the same display flaw occurred. I am nearing the point of giving up. So I'd give the original display five stars, and give the newer display one star, averaging out to three stars.
I have read horror stories about LG service, and I am basically living it. The second time I sent it in, the support rep said that they would probably just replace it - but they did not, they just replaced a different part than they replaced the first time. I don't see how such a visually obvious coloration flaw can pass their quality/calibration checks. [This review was collected as part of a promotion.]
