HDMI Output
Select
• Primary - The HDMI Output of the Io IP is always the primary format. The
current format and frame rate are displayed on the right.
• Stereo 3D - A pulldown menu for 3D output allows you to select either Side-
by-Side or Top-Bottom (Stacked) output of left-eye and right-eye signals.
NOTE: This selection must agree with the format selection in the third-party CineForm
Codec pulldown menu (NOT included with AJA Desktop Software).
Audio Ch
An Audio Channel pulldown allows you to select the number of embedded audio
channels for the HDMI output.
Ch 3/4 Swap
This checkbox controls HDMI input audio channel placement. Some multi-
channel audio decoder systems route the low frequency effects audio to channel
4, and some to channel 3. If you want to monitor or pass audio though to another
device, this control can be used to align these two channels correctly.
• Checked - (default) HDMI audio channel 3 is moved to channel 4's location,
and input channel 4 is moved to channel 3's location.
• Unchecked - HDMI audio retains the original 3 and 4 channel locations.
Protocol
The Protocol pull down allows you to choose between two “Auto” modes, or to
explicitly force the output to a desired protocol.
• Auto Detect - (most reliable) AJA device attempt to reconfigure the HDMI
output to match the current protocol setting of the output monitor. This
option will be the most reliable in creating an output image. However, the
output may result in loss of audio.
• Auto Set - (best quality) The AJA device HDMI out will attempt to
automatically set the output monitor into the best protocol, usually HDMI.
• HDMI - Forces the use of the HDMI protocol regardless of the attached
device’s EDID. Connection may fail if output monitor does not support the
HDMI protocol.
• DVI: - Forces the use of the DVI protocol regardless of the attached device’s
EDID.
Color Space
The Color Space pulldown allows you to choose between two “Auto” modes, or
to explicitly force the output to a desired color space regardless of the attached
device’s EDID or user application needs.
• Auto Detect - (most reliable) AJA device attempt to reconfigure the HDMI
output to match the current color space setting of the output monitor EDID.
This option will be the most reliable in creating an output image. However, the
output may result in an inferior image due to color space conversion and loss
of bit depth.
• Auto Set - (best quality) The AJA device will attempt to automatically set the
output monitor into the best color space and bit depth that matches the user's
application needs regardless of EDID of the output monitor. This may result
in loss of image if the output monitor does not support a specific color space
mode.
• RGBA-8 - Forces the use of RGBA-8.
