What to watch for
Brompton processors only drive panels fitted with Tessera receiver cards. A panel is "Brompton compatible" or it is not, and that is a hardware fact about the panel, not a setting.
Frame rate, genlock and shutter angle are one problem on a camera shoot. The processor can be locked and still beat against a camera if the shutter is wrong, which reads as a processor fault and is not one.
Dynamic Calibration and extended dynamic range features require calibration data loaded for the specific panel batch. Mixing calibrated and uncalibrated tiles in one wall shows up instantly on camera.
