I tried one Blu Ray with this before I packaged it up again, Training Day.
It looked nice, but it still had black bars. I don't have my speakers hooked up yet, but the monitors integrated ones seem okay for casual use.
Lots of movies will still have black bars.. Many are anamorphic ratio of like 2.33:1. HD TVs are 1.77:1, regular 16:10 monitors are 1.6:1 (even larger bars). If the movies were formatted for HD or 16:9 format or otherwise has a ratio of 1.77:1, then they will have no bars. But you might be missing some of the movie.
