This was priced just under $400 less than a couple weeks ago. I think this model is being cleared out and is being replaced by the 27UP650 (current $450), which as far as I can tell, the main difference is an updated stand (please correct me in comments if that's not accurate).
It's also the same price on B&H photo:
2 x HDMI 2.0, DP1.4, headphone out, 3-sided bezel-less display, VESA-mountable and color-calibrated from factory. Stand supports tilt, height and rotate. I quite like the bottom power button/joystick control.
