nView remote adjustments

My nView has a few settings with which I'm not familiar. It has the following:
Text
Rear
Pix Adj
Phase
I don't know what those do. Does anyone know what these do?
I tried to find some info through the search function but found nothing specific.

It also has:
Reset
3 Source Settings
Bright
Contrast
Color
Tint
Horizontal
Vertical
Focus
These all work, I know what they do and I can see noticable change except Focus which I don't really see any difference.
