Actually, the problem is that most of these LED monitors are made with TN panels, which have inferior viewing angles, color reproduction and peak brightness, as compared to IPS/PVA LCDs.
If your friend only wants to go for an LED monitor, then the Samsung PX2370 is a better option for movies, although it is not within the same price range. If he is also considering standard LCDs, then he could go for a Dell (U2311H, U2410, U2408WFP, ST2410 (Hammad's LCD)) or an HP (LP2475w, ZR24w).
