Advanced tab – these controls are provided:
Y Cr Cb R G B
Y Gain G Gain
Cb Gain B Gain
Cr Gain R Gain
Y Offset G Offset

Note that settings made in one tab appear in both. Note also
that while all of the adjustments in the Advanced tab are
independent, the All Gain adjustments in the Basic tab
interact with other settings on that tab.
If you change some settings and attempt to switch
modes, you may be asked to confirm your changes
since they will affect image quality.
3.4.4 The Reference panel
The reference is used to gracefully handle misaligned
hot switches at the input or to use the built-in frame
synchronizer.
-
This panel allows the selection of the reference to be used
by the 3DX-3901.
Use the radio buttons in the Reference Source area to
select from the following options:
• Auto – this mode selects the first source detected in
this order of priority:
o External Reference input
o URS
o Selected Input signal
• External – selects the signal connected to the rear-
panel REF IN connector
• URS (Universal Reference Signal) – selects the
internal reference from the backplane
• Input – uses the currently-selected input signal.
URS Format – use the radio buttons in the URS Format
area to select whether the URS is OFF, 29.97 Hz or 25
Hz.
• When URS is OFF, the URS reference format
source cannot be selected, and will also be ignored
by the automatic detection mode.
Note that there is no external reference or URS support
for 1080p23, 1080p23sf, 1080p25 or 1080p29 inputs.
