I have an Acer XB271 enroute, and I have a PG279Q that I just received yesterday sitting on my desk. Unfortunately, the PG279Q has some funky hole in the screen causing some light to come through. The backlight bleeding on my PG is solid, so I'll have a good unit for comparison.
If the Acer checks out, I'll keep it. I'm not a fan of the pictures of the stand, but if the panel is good, it'll be a keeper. The Asus will go back for a refund. If the Acer is bad, they both go back, except I'll request a replacement be sent from Newegg for the Asus. I just like the stand and bezel of that one much more (although I haven't seen the Acer in person, so my opinion may change).
