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 HDMIDA2 is a quarter rack wide, 1 inch high, and
3inches deep, which allows the unit to be conveniently mounted in a rack or under
furniture.
