Is it possible to add a Full HD test pattern to the Wallpapers.
With a test pattern it’s easier to accurately adjust the brightness, contrast, color and sharpness.
Now you cannot accurately adjust the “color adjustment” with the available wallpapers.
In the current situation to adjust the picture settings for different kind of light conditions,
I rename a test pattern to “a_bg.png” and adjust the picture settings.
The problem is that everytime I restart the projector, it gets replaced with the original wallpaper.
Select "color adjustment"
If I can choose a test pattern as wallpaper.
