Brompton SX40 + XD

10 ports · 9 M px · figures from the maker's specification

This page gives what the Brompton SX40 + XD carries: its ports, pixel capacity and canvas as the sheet publishes them, and how many of each cabinet in the library one port takes at the planner's 80% ceiling.

10 gigabit ports at 525,000 px each at 8-bit 60 Hz, 9 M px in total. The sheet publishes no 10-bit figure; the planner uses theoretical bandwidth, 420,000 px per port. Largest canvas 4,096 wide by 4,095 high.

Source: Modeled with one XD unit: each of the SX40’s four 10G trunks feeds up to ten 1G legs, system capacity 9 M px total. Tessera help, Canvas Resolutions: 4K DCI 4096 × 2160 or UHD native; custom canvases up to 4094 wide (even) and 4095 high.

Walls one unit drives

The largest 16:9 picture inside 9 M px is 4,000 × 2,250 px. A UHD canvas, 3,840 × 2,160 px, fits with 706 k px to spare and needs at least 20 runs at the 80% ceiling, 10 more than this unit has, so it takes a second unit or fuller ports; the wiring plan decides the real count, since runs follow columns. Refresh above 60 Hz scales the capacity down as 60 divided by the rate; 10-bit colour takes it to 420,000 px per port by theoretical bandwidth, since the sheet publishes no figure.

Panels per port

Every cabinet in the library, grouped by resolution: a port carries pixels, so two cabinets with the same pixel count load it alike whatever their pitch or size. The per-port count is at 80% of 525,000 px, 60 Hz, at 8-bit and at 10-bit; the last column is how many of that cabinet the unit's total capacity covers with no ceiling. Rigging, power and the wiring plan for a wall of any of them come from the planner.
