Make the picture fit the wall
Walls are rarely a standard screen shape. Scaling and windowing in the processor decide whether content looks sharp, stretched or cropped.

LED video processors and sending controllers.
An LED wall is only as good as the signal feeding it. HJ plans the video processor, sending controller, cabling and source switching together with the LED display, so the picture fits the wall and operators can change sources without guesswork.
THE STARTING POINT
Start with the everyday problem.
Switch sources without a technician
Laptops, media players, cameras and signage players can be selected from a simple panel or preset, so staff do not touch the processor settings.
Plan the signal path, not just the screen
Cable type, distance, sending and receiving cards and rack power are part of the design, and are tested before the wall is handed over.
LED video processor & controller Canvas
SYSTEMS & SCOPE
Connect the right parts of the LED system.
Choose the areas that match your priorities, then confirm how they work together. Open a topic for related installation or service information.
Fine-pitch indoor LED
Processor and controller settings matched to the pixel pitch and cabinet layout of indoor LED walls.
LED video wall
Cabinet layout, wall size and aspect ratio confirmed so the processor output matches the wall.
Indoor & outdoor LED
Brightness, weather and viewing-distance considerations that change how the signal is set up.
Digital signage & CMS
Scheduled playlists from a signage player or CMS feeding the processor.
Video wall & CMS service
Support for existing walls, controllers and content systems.
Large-venue projection
Where the venue mixes LED and projection, sources and presets are planned together.
Control-room video wall
Multi-window layouts for camera, monitoring and dashboard sources.
Meeting-room & hall AV
Laptop, wireless presentation and camera inputs switched through one panel.
Structured cabling
Signal and network cabling routed, labelled and tested to the rack.
Fibre for long signal runs
Fibre links where the controller room is far from the LED wall.
Backup power
UPS for the processor, controller and player, so a short outage does not leave the wall blank.
LED & signage service
Checks, repairs and re-calibration for existing LED displays and controllers.
Planning the signal path.
New LED wall
- Provide the wall size, cabinet layout and the sources to be shown.
- Confirm where the processor and controller will sit and the cable route.
- Agree the presets staff will use, such as presentation, video and full-wall signage.
Existing LED wall
- Describe the symptom: flicker, wrong aspect ratio, dead sections or slow source change.
- HJ checks the controller, cards, cabling and settings before recommending changes.
- Existing equipment is reused where it meets the agreed requirements.
BEFORE THE QUOTATION

Wall layout
Cabinet count, resolution and aspect ratio.
Sources
Number and type of inputs, and who switches them.
Signal distance
Cable type and any fibre runs.
Existing equipment
What can be kept, repaired or replaced.
USEFUL ANSWERS
Questions before you start.
Do I need a video processor for an LED wall?
Most LED walls need a sending controller to drive the cabinets. A video processor is added when the wall must scale content, show several windows or switch between several sources. The site assessment confirms what your wall needs.
Can staff switch between laptop, camera and signage without calling a technician?
Yes, where agreed. Presets or a simple control panel can be set up for the sources used, and tested at handover.
Why does content look stretched or cropped on our LED wall?
This usually comes from the wall resolution and the processor scaling or window settings, not the LED cabinets. HJ checks the settings and signal path first.
Can you work with an LED wall installed by another contractor?
The assessment checks the controller, cabling and documentation first. Support is confirmed after that review.
Plan your next step with HJ.
Share the wall size, the sources you want to show and what is not working today. We will review the requirements and confirm the next step.
