this is a new build. i have 3 x asus monitors. all 3 monitors are working, but on monitor #3, there is a small rectangular dark gray box (sort of near the center of the screen) with two light gray arrows on the bottom right of it. the box is not clickable or moveable.
system specs:
windows 7 pro 64bit
asus p8z68 deluxe mobo
crucial m4 128gb ssd
silverstone 1000w atx psu
g.skill ripjaws x series ddr3 1866 16gb
intel i5 2500k cpu
asus vw246h monitor x 3
what i've discovered so far:
if i change the order the monitors appear in windows, the dark gray box will always appear on monitor #3, so i don't think it's monitor-related. if i go into the monitor menu and select system setup, then splendid demo mode, and select on, the dark gray box turns light gray on the left side. this has been the only way i've found to interact with it.
here's a screen shot (i've cropped the image, but the box actually appears near the center of the screen and about 3 inches from the top of the screen):
