Hue
As with Saturation, Hue can also be con-
trolled independent of the display. Hue is
the same as the “Tint” control found on
most TVs and controls how colors are dis-
played in the image. The Hue control is
not available for Component or
PAL/SECAM inputs.
YC Delay
Sometimes there is a lag between the
Luminance (Y) and the Chrominance
(C, UV) of the video signal. This will
cause a color “smearing” because the
color component of the image is not
lining up properly to the black and white
luminance component of the image.
The iScan Ultra can compensate for these
errors in the source signal by shifting the
phase of the Y with respect to the C, for-
ward or backward to align them properly.
Use the
▼ and ▲ controls to adjust the
phase and observe the effects on your
display to obtain the optimal setting.
Please note, this control is not applicable
when using a DVI output.
Sharpness
The Sharpness control on the iScan Ultra
has two independently controllable areas
that affect the definition of edges in the
display as well as small details. When you
cycle down to the Sharpness control it
will first go to the ‘Edge Enhance’ para-
meter, which you can adjust using the
▼ and ▲ controls. If you make the edges
sharper, there will be a “halo” effect
around edges. Making them less sharp
will soften edges but remove the “halo”.
Pressing the Picture Control control again
will cycle down to the Fine Detail control,
which you can adjust using the
▼ and ▲
controls. Increasing fine detail will
improve viewing of fine details but may
also increase visibility of noise or other
artifacts in the source signal. Please note,
this control is not applicable when using
a DVI output.
Chroma Filter
The Chroma Filter function corrects a
common problem found in many DVD
players (and other digital set-top boxes
with MPEG decoders), where the Chroma
portion of the signal is not decoded prop-
erly from the source material. This causes
the edges of some colors to appear incor-
rectly on the display. You can identify if
you have this problem by using the
SMPTE test pattern and looking at the red
portion. If you see poor color transitions
or jagged edges where the red transitions
to another color, then you will benefit
from the Chroma Filter feature. For more

To activate the iScan Ultra’s Chroma
Filter, press the Picture Control control
until the LED next to Chroma Filter is
illuminated and use the
▼ and ▲
controls to enable/disable this feature.
