Troubleshooting a Brompton Tessera LED wall
The reference for broadcast, high-end rental and virtual production stages, the Brompton Tessera ecosystem (SX40, S8, S4, M2 processors, R2/R2+ cards) is built for camera capture. Its issues concentrate on the signal chain, genlock and capture configuration.
Degraded or missing image on part of the wall
- Check link status in Tessera: every panel chain reports in real time.
- Swap the fibre or data cable of the affected segment with a known-good link.
- Check the R2 card of the first mute panel (indicators, reseat).
- Verify the mapping in the Tessera project: a panel moved physically but not in the project shows the wrong piece of image.
Camera capture: Tessera's strength, if configured
ShutterSync aligns the wall's phase with the camera shutter: the cure for scan lines on tight shots, configured with the shoot's real frame rate and shutter angle.
Genlock: camera and processor must share the same reference. A slow brightness beat on camera almost always means a missing or doubled reference.
Dynamic Calibration (with the Hydra bench) exploits panels at their best calibrated brightness; after module replacements, check the calibration data follows.
Frame Remapping and Extended Bit Depth answer precise needs (multicam, slow motion, low brightness): document the settings chosen for each shooting configuration.

The wall is perfect to the eye but striped on camera — is Brompton at fault?
No: it is a capture configuration to set. ShutterSync with the right rate plus a common genlock solves the vast majority of cases — see also our camera flicker guide.
What should I watch on a heavily touring rental kit?
Fibre and data connectors (dust, locks), panel-to-project pairing after each build, and consistent Tessera versions across a kit's processors.
Can I mix Tessera firmware versions?
Avoid it within one wall: harmonize processor and R2 versions per kit, out of production, before the tour rather than during it.
Does Lédia know the broadcast environment?
Yes: genlock, shutter angle, ST 2110/IPMX, redundancy: Lédia reasons about the whole signal chain, not just the wall.
