Get the one that has the input that matches your needs & output(s).
For example, the HP only has VGA and HDMI. The AOC has VGA and two HDMI, and the ACER has DVI, VGA, and HDMI.
Aoc or Acer both are pretty good.
just stay as far away as you can from anything that has hp written on it.
edit: i would personally probably go for the Aoc
