You have a strange idea of what a "big flaw" is! The inability to connect an Xbox to it without an adapter isn't something most people would ever think about. Another thing you can't do with the U2412M is lay it flat and use it as a cutting board, because you'd crack the screen! It is, however, designed to be a computer monitor, and does that job extremely well.
