NEW FEATURES
1. Color Management System
This section describes the new features in iScan Duo’s CMS
1.1 Secondary Color Gamut Controls (Cyan, Magenta, Yellow)
Secondary Color Adjustments (x,y,Y) are enabled in the Color Gamut menu. For
example:
Main Menu > Output Setup > Color Gamut > Cyan-x
1.2 Luminance Control for Color Gamut
Color Gamut adjustments now come with luminance control ‘Y’.
The primary colors (Red, Green, Blue) and White each comes with a new luminance ‘Y’
control. For example, Red controls now feature Red-x, Red-y and Red-Y. For example:
Main Menu > Output Setup > Color Gamut > Red-Y
1.3 White-point controls for Gray Scale
Gray Scale controls now also include white-point adjustments as an alternative to using
primaries (Red,Green,Blue).
062210 1
At each IRE setting, in addition to Red, Green and Blue, the on-screen menu includes
White-x, White-y, White-Y adjustments.
Main Menu > Output Setup > Gray Scale > White-x
Main Menu > Output Setup > Gray Scale > White-y
Main Menu > Output Setup > Gray Scale > White-Y
2. Output HDCP Mode can be turned Off
Some applications do not required HDCP content protection. For these applications, the
ability to turn off HDCP on the outputimproves the iScan Duo’s response time when
providing a signal to a display.
IMPROVEMENTS
Updated the automation interface to support new features in this release as well as
Firmware update (0xAD) and system restart command (0xAE).
All solid color test patterns are now at 75 IRE.
Avoid front panel LED flashing when both A/V HDMI outputs aren't connected.
Added support to changing output settings without a display.
BUG FIXES
Test Pattern on-screen indicator did not show correct test patterns when using
remote short-cut buttons.
Serial automation command for Zoom (0x46) only accepted integer values.
Front panel menu text and back light remained on when exiting main menu.
At 1080p output, lower part of gamut selection menu remained at bottom of screen
when opening edit control.
Changing the output resolution from SXGA to VGA and cancelling the operation
would cause the system to be unresponsive.
CEC pass-through did not work.
Info screen page rolled over on front panel display but not on the OSD.
KNOWN BUGS
If 100 IRE Gray Scale adjustment is selected, moving to Color Gamut adjustments
and back to 100 IRE Gray Scale will cause the iScan Duo to output wrong gray scale
level. Selecting 90 IRE and back to 100 IRE levels fixes the problem.

DVDO iScan Duo
Owner’s Manual Supplement
Firmware Version 2.10 (Build 062n)
This document provides additional information for the DVDO iScan Duo configured with

1. Color Management System improvements
This section describes improvements made to the iScan Duo’s CMS.
1.1 User Chromaticity
The iScan Duo now features a User setting under the Chromaticity menu.
Main Menu > Output Setup > Chromaticity > User
This feature allows the user to obtain the display’s chromaticity values manually if a) the
value obtained from the display EDID (Auto) or b) the preset values provided in the
Chromaticity menu do not accurately reflect the actual display’s performance.
Here are the steps to obtain the display chromaticity values directly
1. Obtain a good color meter
2. Turn on the iScan Duo’s test pattern generator (TPG) using the following
methods
a) Use the menu system
Main Menu > Output Setup > Test Patterns > On
b) Use the Test Pattern On/Off button on the remote control.
3. Set all Color Gamut Offset and Gray Scale offset values to zero.
Alternatively, turn on CMS Bypass (see below)
4. Go to the User menu and select the first item, Red-x
Main Menu > Output Setup > User > Red-x
062210 3
The TPG automatically generates only the Red primary (75IRE).
5. Enter the measured Red-x value. Note the indicators reflect only the output of
the Test Pattern Generator.
6. Select Red-y and enter the measured Red-y value
7. Repeat step 4,5 and 6 with Green-x and Green-y
The TPG automatically generates only Green primary (75IRE).
8. Repeat step 4,5 and 6 with Blue-x and Blue-y
The TPG automatically generates only Blue primary (75IRE).
9. Repeat step 4,5 and 6 with White-x and White-y
The TPG automatically generates only White primary (75IRE).
10. Output chromaticity should now match your display’s actual chroma response.
If necessary, the chroma and luma can now be fine-tuned using the Color Gamut
and Gray Scale controls.
1.2 CMS Bypass
In some cases, it is helpful to bypass the CMS when calibrating a display (see User
Chromaticity Control above). The CMS Bypass control is available in the Output Setup
menu.
Main Menu > Output Setup > CMS Bypass
On Signals coming into the iScan Duo bypasses the
Color Management System.
Off (default) The Color Management System is enabled.
2. Per input per format saved settings
Input settings are now saved per format supported by the input. Different inputs
support different formats. For example, Video (composite), S-Video inputs support
NTSC (480i 60Hz), PAL (576i 50Hz), 240p 60Hz and 288p 50Hz, while Component video
and HDMI inputs can support other formats including HD and PC formats.
The iScan Duo will save input settings for each format (if supported by the input) below.
