The 6042QM is a gimmick, was dead cheap. The 9044QM inch is my travel pvm
The 20F1E is my main screen, the 20M4E is in my bedroom.
The two 14 inch screens need more or minor fixing and will find a nice home at my friends.
BTW, I had more at home, I already gave away my 2130QM, the 20M7MDE and my 2042QM
