4.1.4 Scaling limitations


When scaling an SD 4:3 input (e.g.: AFD Code: 4:3_8) to a 1920x1200 monitor the output image will not fill the
monitor as it should. The aspect ratio will be maintained.

When scaling an SD letter box input (e.g.: AFD Code: 4:3_4) into a 1920x1200 or 1920x1080 monitor the output
image will not fill the monitor as it should. The aspect ratio will be maintained.

4.1.5 Processing delay


The Kaleido-

Solo‟s video processing delay is about 1 frame when the input frame rate is equal to half of the output

rate (e.g.: i60 to p60). In all other cases the processing delay is kept to its minimum. Audio delay is adjusted
accordingly.

4.2 Audio


Kaleido-

Solo doesn‟t decode compressed audio. Selected compressed audio will be passed through HDMI and

SPDIF interfaces unprocessed.

Note that if you pass compressed audio through to the HDMI output, you must use a monitor that
supports compressed audio.
