What an LED processor calculator estimates
An LED processor or sending-card plan starts with total pixel count. A screen with 2,400 × 1,350 pixels has 3.24 million pixels before spare capacity. The processor must support the total pixel load, required inputs, refresh behavior, color depth, scaling, and data output layout.
This calculator gives an early capacity estimate. It does not replace a NovaStar, Brompton, Colorlight, Megapixel, or manufacturer-specific configuration. Always match the final design to the exact controller model and receiving card system.
| Term | Meaning |
|---|---|
| Total pixels | Width pixels × height pixels of the LED wall. |
| Processor capacity | Maximum pixels a processor can drive under a given configuration. |
| Data port capacity | Approximate pixels supported per output port, depending on system settings. |
| Spare capacity | Headroom for mapping, changes, redundancy, and design margin. |
When processor planning becomes important
- Large LED walls with millions of pixels
- Ultra-wide stage screens or custom aspect ratios
- Church IMAG systems with live camera feeds
- Corporate or broadcast environments needing reliable scaling
- Rental walls that change layout often
- High-refresh or high-frame-rate applications
Processor planning is not just about total pixels. Input format, backup signal paths, low-latency requirements, and content workflow can change the required equipment.
Processor planning examples
| Scenario | Planning note |
|---|---|
| Church LED wall | Check lyric slides, sermon notes, and live camera routing. Leave spare capacity for future screen expansion. |
| Stage LED backdrop | Video playback, media servers, and custom mapping may require more advanced processing. |
| Retail display | Resolution and media-player output format should match the wall's actual pixel dimensions. |
| Conference room wall | Make sure common laptop or presentation resolutions scale cleanly to the LED wall. |
Questions to ask before buying a processor
- What is the exact LED wall pixel resolution?
- What input signals are required: HDMI, SDI, DisplayPort, media server, or switcher?
- What refresh rate, color depth, and grayscale performance are required?
- How many output ports are needed for the cabinet map?
- Is redundancy required for events, broadcast, or mission-critical displays?
- Will the screen size expand later?
LED processor FAQ
Is processor capacity only about total pixels?
No. Pixel capacity matters, but input format, refresh, color depth, port mapping, scaling, and redundancy also affect processor choice.
What is a sending card?
A sending card or controller output sends mapped pixel data to receiving cards in the LED cabinets. Naming varies by brand and system.
Should I leave spare processor capacity?
Yes. Spare capacity helps with future expansion, mapping changes, redundancy, and avoiding designs that run at the edge of capacity.
