Thank you very much for your feedback, I understand it now. Do you think it would be a feasible thing to put a small bubble in the display settings like it's the case for the other settings to explain to the users what you explained to me? Sio that everyone can understand that 203 is the SDR brightness according to the standard. Best regards. -- You are receiving this mail because: You are watching all bug changes.
