1:1 Frame Rate

Disabled
The output frame rate from the iScan Duo is fixed.
Enabled The output frame rate from the iScan Duo tracks the input frame rate.
This avoids performing frame rate conversion, which can result in stuttering
motion in some cases.
The 1:1 Frame Rate feature is useful when you need to display video from both 60Hz and
50Hz sources, as long as your video display can operate at both frame rates. Some video
sources, such as Blu-ray players, can output 24Hz video. If you have a 24Hz source and
your display can also accept 24Hz, enabling 1:1 Frame Rate will allow the 24Hz video to pass
through the iScan Duo from source to display.

Frame Lock

Auto Lock The output frame rate from the iScan Duo is fixed and locks to the input
when possible.
Unlock The output frame rate from the iScan Duo is fixed and not locked to the input.
Frame Lock provides more options for handling input and output frame rate and timing variations.
In some cases, this feature may provide smoother operation when switching input sources
or formats.

Aspect Ratio

Aspect Ratio sets the display aspect ratio. If you have an HDMI display, Auto (default) is
the safe choice.
Auto The iScan Duo outputs the preferred aspect ratio reported by the display.
16:9 Sets the display aspect ratio to 16:9
4:3 Sets the display aspect ratio to 4:3
•

Color Space

Color Space provides four choices for output color space. If you are unsure what to use,
Auto (default) is the safe choice.
Auto The iScan Duo outputs the preferred color space reported by the display.
RGB Red, Green, Blue color space standard using 8 bits per color.
YCbCr 4:4:4 Component color space used for video standards; 8 bits per component.
YCbCr 4:2:2 Component color space used for video standards: 10 bits per component.

Colorimetry

Colorimetry refers to the standards by which RGB is converted to YCbCr. There are two stan-
dards for performing this conversion:
ITU BT .601: This is the colorimetry standard for Standard Definition video formats.
ITU BT .709: This is the colorimetry standard for High Definition video formats.
Auto The iScan Duo outputs the colorimetry standard reported by the display.
ITU BT.601 The iScan Duo outputs BT.601 standard
ITU BT.709
The iScan Duo outputs BT.709 standard

• Video Level
This control is similar to the Video Level control in the Input Adjust menu but applies to the
iScan Duo's output.
Auto The iScan Duo outputs the video level reported by the display.
Video The iScan Duo outputs 'video' signal level to the display.
Computer The iScan Duo outputs 'computer' signal level to the display.

Deep Color

The iScan Duo supports Deep Color displays. These displays support 30-bit or 36-bit inputs.
If the display connected to the iScan Duo supports Deep Color, the iScan Duo's output can
be configured as follows.
Off The iScan Duo will not output Deep Color format (default mode).
Auto The iScan Duo will output the display's preferred Deep Color format.
30-bit The Scan Duo will output 30-bit Deep Color format.
36-bit The Scan Duo will output 36-bit Deep Color format.

Audio Output

The iScan Duo can output audio on one of the following connectors: HDMI Video 1, HDMI
Video 2, HDMI Audio, Optical.
Auto Select The iScan Duo will automatically route audio to an audio output.
The choice of output depends on what components are connected to the outputs
and powered up.
Video HDMI Use this setting if you want to send audio to your video display's speakers.
Audio HDMI Use this setting if you have an AV Receiver with an HDMI input.
Optical Use this setting if you have an AV Receiver without HDMI inputs.
The table below shows the connector choice for audio when Auto Select is chosen.
Output Connector Conditions
