Q: Mac Pro exit's standby every time with BenQ XL2720T
I've connected one BenQ XL2720T display to my Mac Pro. When this display is turned on it prevents the mac from staying in standby mode. This is what happens:
1) The mac puts the display in standby mode after a few minutes. (The led on the display turns red)
2) The mac enters standby mode.
3) The display looses the video signal and wakes up, displaying an error message.
4) When the display wakes up the mac seams to handle this as an "Plug in display" event and exits the standby mode.
This game can run for hours. The only way to prevent it is to manually shut off the display. Is there maybe a way to disable the "Plug in display" event? (As seen on this page About standby on your Mac - Apple Support)
Mac Pro (Late 2013), OS X El Capitan (10.11.6)
