Kean Production Services and Red Rock Ops built a measured colour pipeline for a three-day conference with one main LED wall and 24 projectors. The team targeted Rec.709 across the different display technologies rather than trying to force projection to reproduce LED primaries it could not reach.

A Klein K-10A meter was profiled for each display type with a Colorimetry Research CR-250 spectroradiometer. Calman generated correction LUTs, Livegrade managed them and four AJA ColorBox processors applied the transforms on the projection paths. Brompton SX40 processors carried the LED correction.

The resulting measurements were reported below 2 dE2000 between the main projectors and LED wall and around 3 dE2000 on delay screens. A mobile measurement cart let the colourist adjust individual zones from the floor as ambient conditions changed. UDC-4K converters simultaneously produced UHD and HD paths for display, stream and recording needs.

This is a supplier case study rather than an independent test, and it covers one event. It does not publish pre-calibration error, total setup time, drift across the three days or added end-to-end latency, though the team said latency was not a concern for IMAG.
