Precision Video Processing for Any LED Display
Modern LED walls demand more than just sender/receiver hardware.
GeoBox adds an open, professional video-processing layer in front of any LED controller—to make the content actually work.
For system integrators, LED brands and AV consultants working with complex LED walls.
Why Most LED Walls Fail Client Expectations
Clients invest heavily in LED walls and expect “basic” capabilities: multiple sources, flexible layouts, reliable BYOD, smooth switching.
Standard LED controllers were never designed for this level of processing.
“Why can’t we show multiple 4K sources on one canvas?”
“Why does the image stretch on this ultra-wide LED wall?”
“Why do laptops randomly go black or show the wrong resolution?”
“Why can’t we mix LED with LCD and projection in one workflow?”
💡The problem is not the LED wall. The problem is the missing processing layer between sources and the LED controller.
LED Controllers vs. Professional Video Processors
LED controllers are excellent at driving LED modules.
Professional video processors are designed to prepare, shape, and manage signals before they reach the LED system.
| LED Controller (Sender / AIO) | Professional Video Processor (GeoBox) | |
|---|---|---|
| Primary Role | Pixel routing, synchronization, LED driving | Scaling, cropping, multiview, custom timing, switching |
| Sources | 1–2 basic inputs | Multiple UHD/4K inputs, BYOD ready |
| Layouts | Simple, fixed, limited PiP | Flexible multiview, custom layouts |
| Output Timing | Preset formats | Fully programmable custom resolutions |
| Technology Scope | LED only | LED + LCD + projection |
💡LED controllers make the wall light up. Professional video processors make the content usable in real workflows.

Where an Open Processing Layer Makes the Difference
Museums & Exhibitions
Immersive exhibitions and cultural spaces often use non-standard LED canvases and mixed source and display technologies.
Commercial Spaces
Retail, corporate lobbies, and public displays require reliable multi-source presentation and consistent visuals.
Education & Trainings
Training centers, simulation rooms, and universities rely on synchronized, low-latency multi-source display.
Conference Rooms & Live Events
Meetings, auditoriums, hybrid events, and stages need smooth switching and stable source management.
