GerdS, I can speak directly to your issue. I can tell you that RSG panels do not auto adjust to ambient lighting conditions in the space in which the flight sim is setup. E.g., on a recent flight at "night", over a very, very dark landscape and with the lights off in my Sim Room, the glare from RSG PFD/MFD was so bright relative to the real-time/weather on approach into KUNV, I had to shield my eyes from the RSG glare to be able to see the runway to land. I talked with RSG, and its superb support team. I was advised that unless I am on a windows machine with a graphics card that itself provides for changing the illumination on the RSG panels, I'm out of luck. I'm on MacOS. So, is there a way for you to modify the ambient light conditions in the room in which your Sim is located? HTH, Anthony
