CLAMP is used as a standard for setting the black
level of a picture correctly. The standard position of
the clamp depends on the kind of sync signal being
used. Normally, the projector CPU judges the signal
and sets the position automatically. However, the CPU
can misjudge the signal because of noise. If the
luminance of the picture seems to be incorrect, the
clamp position may need to be changed.
AUTO: Automatic setting mode. Normally set to this
position.
SonG: Set to this position if the black seems too light
or greenish.
H/C: Set to this position if the picture is too dark or
luminance is unstable.
HP: If the luminance is still incorrect after changing to
the SonG or H/C position, set to this position and
perform the H-SHIFT adjustment.
TRI-LEVEL S: Set to this position if the picture is
dark when using the tri-level sync.
Notes
• If the external signal does not have the SonG signal,
the H/C position is recommended.
• If the luminance is still incorrect after changing the
clamp setting, check the input signal and the
connections.

WIDE: Normally, set to this position (factory preset).
NARROW: When some signal such as a
superimposed signal with unstable vertical sync.
signal is input, the picture may be distorted
vertically. In this case, set to this position.
Adjustable range in the lower direction will
become narrow.
Note
When the video, S video, component or SDI 4:2:2
signal is input, V SHIFT is fixed to NARROW.
SYNC SEL (select)
Selects the sync signal when using an external sync
signal.

When an RGB signal is input
AUTO: Automatic setting mode. Normally set to this
position.
SonG: Set to this position if you project the picture
using the sync on G signal.
C: Set to this position if you project the picture using
the composite sync signal.
HV: Set to this position when using the horizontal/
vertical sync signal.
