Output Compatibility Correction — The HDMI DA2 monitors the EDID of each connected
display to ensure it is compatible with the current input signal. The following adjustments are
made for each output independently:
z Interface format: If the connected display is DVI and the input signal is HDMI, the signal
is reformatted to DVI. If the output is HDMI and the input is DVI, no reformatting is needed
because HDMI is backwards compatible with DVI.
z Video color bit depth: If the connected output device does not support the color
bit depth of the input signal, it is truncated down to the next level that is supported
(12-bit > 10-bit > 8-bit). The signal can be forced to always truncate to 8-bit via Simple
Instruction Set (SIS
™
) commands, disabling deep color.
z Audio: If the connected output device does not support the audio format of the input
signal, audio is muted.
NOTE: These adjustments do not affect the actual video or audio data (there is no video
scaling or audio decoding or mixing). It is up to the user or installer to ensure that
the connected display device is compatible with the video resolution of the input
signal.
Easy mounting options — The HDMI DA2 is a quarter rack wide, 1 inch high, and 3 inches
deep, which allows the unit to be conveniently mounted in a rack or under furniture.
