HRE ANSWERS • DISPLAYS & PROCESSING
Planning video processors for LED walls begins with the show’s requirements: what needs to appear, where it belongs, and how operators will change it. Before choosing equipment, document the source-to-screen path and agree who is responsible for each stage.

How Video Processors Level Up Your LED Wall
Start with the picture the audience needs
Make a list of the content the wall must show: presentation slides, camera images, playback or combinations of those sources. For each show moment, describe the required layout and transition. Use a simple drawing that everyone can review before hardware choices become fixed.
- Which sources must be visible at the same time?
- Which changes happen live, and who calls them?
- Does the design require separate regions or one continuous image?
- What should the audience see if a source becomes unavailable?
Assign processing responsibilities explicitly
Do not assume that every function belongs in a separate box. For example, Brompton documents scaling, clipping and colour adjustment on its Tessera T1 LED processor. That is a model-specific example, not a statement that every LED controller has the same capabilities.
Ask the team to identify where each required task will happen: source selection, image sizing, composition, mapping to the screen and operator control. Check the actual models and configuration against their documentation. This avoids planning the same task twice or leaving it unassigned.
Agree the handoff with the LED-wall provider
Request the wall’s pixel map and the expected input arrangement. Record each supplied feed and the screen area it serves. Where content has to cross a boundary between surfaces or feeds, include that behavior in the rehearsal plan.
- What image dimensions should the content team deliver?
- What signal format should each input receive?
- Which equipment performs cropping, scaling and positioning?
- Who owns the screen map and approves changes?
- How will the team confirm correct framing and alignment?
Keep physical screen dimensions and pixel dimensions in separate fields. Both are useful project inputs, and a labeled drawing makes the handoff easier to review.
Build a source and output worksheet
Create one row per source: source name; connector; requested format; receiving input; required screen region; operator; fallback. Create a second list for outputs: output name; destination; required format; assigned screen area; cable path; verification result.
These are planning fields, not promises that a particular processor supports every requested format or layout. Resolve each requirement against the proposed equipment before the final system is approved.
Rehearse the show workflow
Use representative slides, motion content and camera images during preparation. Check the intended layouts, source changes and recovery actions. Record the result on the same worksheet so an unresolved issue is not lost between the shop and show site.
As part of the handoff, capture the approved screen map, configuration versions and operator notes. A second technician should be able to identify which source feeds each destination without relying on memory.
