Chroma sub-sampling reduces bandwidth
& is usually visually undetectable.

Avoid on LED screens, or use pixel gaps
between regions to prevent colour bleed.
Network overhead
& other data
<10Gbps =
Fits on only 1 link
Likely OK for multiview

10-20Gbps =
Needs both links
Reconsider for multiview

>20Gbps=
Cannot transport,
reduce bandwidth
