I've had this issue a couple of times now (only owned the monitor for 2 weeks). After turning the monitor off and then turning it on later, the screen is completely blank. At first I thought the display was broken as tried different displayport and HDMI inputs and nothing presented an image. Then realised via another forum that somehow in the menu settings under "colour" it had defaulted to colour temperature "blue light" and all colours had been moved down to 0. Changing the colour settings back to user or anything else returned the image.
Has anyone else had this issue - are Acer aware and is a firmware update planned to stop this annoying bug from happening?
