Bought an LG 27" UHD (I think model no. 27UD68) monitor close to 2 years ago and it has really changed things when it comes to photo and video editing!
It was well calibrated out of the box, other than adjusting the backlight levels - the colours were pretty accurate (sRGB).
I use an X-Rite i1 displaypro calibrating puk & software and I have not seen much drift in the monitor in that time.
It was the cheapest 4K monitor at the time, the stand was not as adjustable as the more expensive models and had less chrome/silver finishings, but the panel itself delivered the goods!!
