PixelTach guides
Short, practical answers on video timings, bandwidth and EDIDs for live events. Every number comes from the PixelTach calculator.
- Can HDMI 2.0 carry 4K60 at 10-bit?Which bit depths and color formats fit HDMI 2.0, HDMI 2.1, DisplayPort 1.2 and 1.4 at 4K60.

- How to calculate pixel clockThe formula, worked examples for 1080p and 4K, 59.94 Hz, data rate and why EDIDs round the clock.
- Custom EDIDs for LED processors and media serversHow to build and load an EDID for an odd LED canvas size so a media server outputs it pixel for pixel.
- How to plan a live event video systemWork from the screens back to the sources: show rate, link checks, converters, routing, cable numbers and a load-in checklist.
