Hi!,
i have a question about my Samsung UEC5100QW. First, I have been rash enough to make changes to the service menu

and i don't know how to revert those changes. I have resolved the "HDMI Calibration Failure" correctly (using "8x8 1080p FULL RGB chessboard pattern") but, for the other values, i don't know if i have changed something or not. In the first "Option" page, my Model is correct C5100 but i don't know my "Type". Somebody could help?
