Dear who it may concerns,
after struggling with the firmware update for the MK3 (Windows User) for two days, now the next issue with this Keyboard. The display brightness and contrast dropped during the use and is now on an absolute desaster, as it is nearly not possible to see anything on this display. The Hardware settings have not been changed from my side and even turning the brightness controls to 100 do not bring back the display brightness. My question: Do any of you have the same effect? Can this be a firmware problem or is the display already broken after a week?
