Source note
The document states one control range for both modes (2.6 million pixels) and no per-port capacity. hdmiInputs counts HDMI IN and HDMI LOOP; hdmiOutputs is the HDMI OUT monitoring output. 4G/5G is an optional module. The cover prints Version 1.4, while the version description on the last page ends at V1.3. The document does not state an output frame rate; 60fps appears only in the video decoding table.
