Seems like a huge discount? Down from $409. I've pulled the trigger, hopefully it's worth it. From what I gather it's a step down from the venerable 27GP850 with nano IPS but hey it's quite a bit cheaper.
One gripe I've been seeing regarding LG monitors with this kind of stand is that the vesa mount points are recessed, making it harder to find a suitable bracket that fits.

300 nits is a joke.
