Hi, this morning i put on the TV, there was an update. Since then, i have duplication of all inputs (android home screen, HDMI4 tv signal, etc...) So i have double screen (see this image: https://imgur.com/a/hKWpOfU ) I've read about secret settings (motherboard settings?) available through some codes (eg 1147) in the normal settings menu but cannot get into such thing to fix this. Also, how would i be able to rollback the update? Customer support is not available by phone, and the support section of the medion website is under construction. Any help would be truly appreciated!
