New information has been added the Advanced Operation page for displays that are badly pre-calibrated and cannot be set to their native/uncalibrated state, as with some projectors from the likes of JVC/Epson/etc.

The example used is a genuine projector very badly manufacturer pre-calibrated to Rec2020, in use with an external LUT Box such as Lumagen, madVR, Tetratune.
The unique Reduced Gamut approach available within ColourSpace is the only way to accurately overcome such display issues!
