Magnimage LED-780H Video Processor for Four-Screen Splicing
The Magnimage LED-780H is a video processor with four DVI output groups for screen splicing or independent display control. The brochure lists up to 8 million pixels across the processor. Match the output timings and downstream LED sending system to the actual screen layout before ordering.
For 4K input planning, the LED-780H user manual V1.2 specifies DP input at 3840 × 1080, 60 Hz, or 3840 × 2160, 30 Hz. Do not interpret the product’s 4K label as a guarantee of 3840 × 2160 at 60 Hz on every input.

Standard Connections and Output Groups
The interface reference below follows the linked LED-780H brochure and manual V1.2, especially printed pages 8–11. Expansion modules depend on the configuration supplied.
| Connection | Standard arrangement |
|---|---|
| Video inputs | 2 DVI, 2 HDMI 1.3, 1 DP and 1 SDI input with SDI loop |
| DP input timings | 3840 × 1080 at 60 Hz or 3840 × 2160 at 30 Hz, as listed in V1.2 |
| DVI outputs | 8 connectors in 4 groups; each group has an A output and a B backup output |
| Control | Front-panel controls, network host control, USB and RS232 |
The paired DVI connectors do not provide eight independently configured output groups. Confirm the four-group mapping, resolution and backup connection plan with the downstream sending equipment.

4K Expansion Boards and Optional Modules
Magnimage’s August 10, 2017 technical bulletin describes the following expansion options. Select one connector on the board for the active input; two physical connectors do not mean two simultaneous sources.
| Optional board | Connectors | Listed input timings |
|---|---|---|
| HDMI 1.4 | 1 HDMI + 1 DVI; select either | 3840 × 1080 at 60 Hz or 3840 × 2160 at 30 Hz |
| DP 1.1 | 1 DP + 1 DVI; select either | 3840 × 1080 at 60 Hz or 3840 × 2160 at 30 Hz |
Extended VGA, DVI, SDI or DP input configurations, Genlock synchronization and the monitor module are configuration-dependent. The brochure marks Genlock and monitoring as expansion modules. Confirm the installed boards and current availability; the original rear-panel photographs show a configured example.

Splicing, Layers and Installation
The LED-780H supports horizontal or vertical screen splicing, custom input/output resolutions and EDID management. In non-splicing mode, an output can display four independent pictures with adjustable source, size and position. Choose the operating mode before specifying the picture layout.
Preset recall, image cropping, freezing and preview switching support prepared show workflows. For a replacement, retain the existing output map, input timings, software details and downstream controller configuration.

Frequently Asked Questions
1. Does this processor connect directly to LED receiving cards?
Its program outputs are DVI connections. Plan compatible downstream sending equipment and receiving cards; do not treat the network control connector as a numbered LED data output.
2. Are Genlock and output monitoring included?
They depend on the installed expansion modules. Specify synchronization and monitoring requirements in the inquiry, and confirm the actual module list on the quotation.
3. What is needed for a very wide screen?
Provide the full canvas, output-group resolution, frame rate and source layout. The maximum custom width and height are separate limits, and total pixel count alone does not establish a supported timing.
4. Which software should I install?
Request a software package matched to the unit and firmware. The linked manual covers V1.2 operation; confirm compatibility before updating an existing installation.
