HDMI Video Data-Rate, Chroma & End-to-End Headroom Planner
Estimate one uncompressed video payload, compare exact source-to-display link caps, expose the governing bottleneck and test lower-chroma alternatives.
Will this video format fit the entire HDMI path?
Calculate an active-pixel payload with an explicit timing allowance, then compare it with the lowest exact cap across source, intermediary, cable and display. Passing this estimate is not a signal-lock guarantee.
Method
Payload uses resolution × refresh × bits per pixel, where chroma changes bits per pixel; an editable timing allowance is added before the result is compared with every user-entered link cap.
Important limitation
The planner cannot infer EDID, DSC, HDR transport, firmware, port mode or certified cable performance. Exact manuals and a physical end-to-end test control.
