You need to assess if the display is responding the same to different inputs compared to its internal patch generator.
You then need to assess if different input sources result in different levels on the display.
Then you can define where this different is coming from - the difference you have already seen, so something is 'wrong' somewhere...
You cannot assume anything - you have to define exactly where the difference is being generated.
It could be anything, other than LightSpace, as that always just sends an RGB Triplet value that is always the same value.
