X10) = PIP window input selection: 0 to 4

X10! = Audio level adjustment range: -15 to +9 dB

X10@ = Audio gain adjustment range: 0 to 9 dB

X10# = Audio attenuation adjustment range: -15 to 0 dB

X10$ = Volume range: 000 to 100, (always returns 3 digits)

X10% = PIP window size: 1 = 1/4, 2 =1/9, 3 = 1/16, 4 = 1/25, 5 = Side by side normal, 6 = Side by side full screen

X10^ = PIP audio setup: 1 = follow main window, 2 = follow PIP window, 3 = toggle audio

X10& = RGB delay: 0 to 10 (0 to 5 seconds in 0.5 second steps).

X10* = Scaler resolution/EDID emulation:
0	= automatic: match current output resolution (default)
1	= match display device (defaults to 1024x768/60 if display cannot be read)
2	= custom EDID	3 = custom EDID	4 = custom EDID

For variables 10-78, see the following table
