Does the same effect occur in BIOS or another O/S?

Just for clarification, that white box appears on both monitors or just one?

nope jus tone of the monitors... very strange! Im using HDMI for that monitor and if i swap to another HDMI-monitor (same res) the box is gone When I swap betweet the monitors its the same on the hdmi (using hdmi for one and dvi for another). the hdmi always got the white box with the AOC monitor...
