Review on Acer KA220HQ 21.5 inch Viewable Monitor: 1920x1080P, 60Hz, Tilt Adjustment, HD Display by Jared Clayton

If you don't have high expectations for your screen, this option is fine. But if you plan to use it for design or as a screen for watching movies, forget it. The brightness is difficult to control, it differs in different parts of the screen, so the colors don't match. Once you get a little further away from the screen than you're working on (e.g. watching a movie) it becomes even more apparent, and if the screen isn't at the exact angle you forget to understand what's happening in the movie when the scene is a bit dark.
