The 0.5″ in-screen boarder a few have mentioned does exist, and does take the true screen size down from the advertised 30″. The other is if you plan on achieving 200Hz refresh rate, you’ll need a display port on your pc. My Alienware lappy doesn’t have a DP, only HDMI so the best I can get is 165Hz (still amazing).
