Here are some of the key specs:
-4ms response (GTG)
-300 cd/m^2 (typical, 250 min)
-Vesa 100x100 compatible
-HDMI x2, DP x1
Very similar monitors have been selling recently for $350, so with tax, Costco is right on par with that price. This deal, however, affords the opportunity to get the panel in store, get it home, and be sure it doesn't have any dead pixels and/or isn't a lemon. That was worth quite a bit to me!
