Similar to my AOC monitor, that has this joystick-button hidden in the rear of the frame, that is very annoying during the power-off procedure.
Also, if the screen passes from "source lost" to standby (after turning off the pc) the pressing procedure should be repeated, and if you don't take care to the monitor, you stay here pressing the button 30 seconds for nothing...
Also x2 this AOC gaming monitor is the worst screen I've ever seen, its okay for gaming/video, while for every else use is absurdly too darker or too brighter (too bright even with luminosity set to 0 and adjustable only by a "shadow control" option, which is causing loss of image detail).
So also acquiring a new laptop is now a pain in the ass... good to know.
