Bought one. Coming in tomorrow. PRIME is the best.
Got it today. No dead pixel. Good color. Lots of options in the menu. 2 HDMI and 1 DP. PIP/PBP. 4 USB ports. Couldn't test G-Sync because I'm use a 980ti. Almost as good as the Dell S2721DGF. It's a great buy at $300 for a IPS 144Hz. Will run some more test this coming week. Will probably look into upgrading the video card for G-Sync in the near future.
