Yes, i know what you are thinking about.
I might have mentioned it earlier, i have a background in image editing and monitor hardware- and software-wise calibration in the graphic arts indurstries for about … well… since ancient times.
What this thread is meant to aim at is a partial (!) increase of lighting within the cockpit´s dashboard only by brighter instrument lights.
You have absolutely no chance to create a similar strong change or effect in an defined part (!) of an image by adjusting your monitor. If you increase brightness and/or contrast and/or gamma in a way, that would be needed to get as bright and nicely readable instruments as introduced in the screenshots before, you would totally kill any other lighter and mid-ranged tones and colors on your screen, resulting in something heavily over-exposed like this “simulated image” here:
In this example you would not see any clouds or anything on the horizon anymore by adjusting your monitor in a way, to get instrument lights similar-ish bright.
We need it to be “partial”, just for the instruments, which are illuminated more or less, depending on the setup for the lights of it.
