I'm not 100% sure that's not a PVA. The last shot from below is holding it's colour far better than the TN on my laptop here. My laptop screen, all the colours invert at about 10 degrees below. Don't take the 180/180 viewing angles literally, even a CRT doesn't have 180 degree viewing angles. The angle quoted is usually something like where the brightness drops to 1/10th of that from head on.Yep: http://forums.overclockers.co.uk/showpost.php?p=11221244&postcount=2513
This makes me wonder if the glossy screen isn't even related to TN panels...
Did you send it back and did they send you a screen with better viewing angles?
