Huidu HDP901 LED video processor and splicer
The HDP901 handles live video sources, two-channel screen splicing and monitoring for LED display systems. It provides DVI outputs for the sending system, picture-in-picture, chroma key and four user presets. Optional SDI adds a further input and loop-through connection.
HDP901 specifications and source notes
Reference: original V1.2 specification dated December 17, 2017 and V1.2 user manual dated December 18, 2017. Differences between the documents are identified below instead of combining them into an unsupported maximum rating.
| Processor role | Video processing and two-channel splicing with a separate monitoring output |
|---|---|
| Inputs | 4 composite video + 2 VGA + 2 DVI + 2 HDMI; 1 SDI optional (11 inputs when equipped) |
| Input timing | VGA/DVI up to 1920 × 1080 at 60 Hz; HDMI lists 480i/p, 576i/p, 720p and 1080i/p |
| Main / monitor outputs | 4 DVI connectors arranged in A/B groups; 1 DVI monitor output; SDI loop optional |
| VGA output note | A VGA output is mentioned in the signal table but not listed among the output connectors; confirm actual availability |
| Custom output reference | 5.3 million pixels at 60 Hz across A/B; documents also list 30 Hz custom modes. Confirm the selected timing and sending-card arrangement. |
| Documented 60 Hz modes | 3840 × 1380, 7680 × 640 and 2560 × 1920 appear in the resolution tables |
| Resolution discrepancy | Specification feature list says 7840 × 640 at 60 Hz, while its table and manual say 7680 × 640. Confirm before designing an ultra-wide screen. |
| Image functions | PIP/POP, chroma key, crop/full-screen display, freeze, cut/fade switching |
| Presets / sending cards | 4 user presets; space for up to 4 sending cards, not confirmation that cards are included |
| Power | AC 100–240 V, 50–60 Hz; manual lists 45 W internal supply, 22 W maximum consumption and 4 × 5 W sending-card load as separate figures |
| Dimensions / weight | 483 × 280 × 69 mm including mounting ears/connectors; net 4 kg |
| Temperature conflict | Specification: working 0–45°C, storage −40–105°C. Manual: working 0–50°C, storage −40–70°C. Confirm the applicable rating. |
Plan the splicing and signal path
Define the complete LED canvas, A/B output layout, source timings and compatible sending cards before configuring the processor. Use the monitor output to check the live image and transitions. A large custom output resolution does not by itself establish the load of the installed sending cards.
For overlays, check the PIP input-pair restrictions and the manual’s cut/fade limitation. Save the required scene presets after setup and retain the installation parameters for future changes.

Frequently asked questions
Does HDP901 include LED sending cards?
The chassis provides installation space for up to four sending cards. This is not a statement that they are supplied. Confirm the card models, quantities and required LED loading with the order.
Are all eleven video inputs standard?
The total includes optional SDI. The listed base inputs are four composite, two VGA, two DVI and two HDMI. Confirm whether the SDI input and loop output are installed.
Can I use picture-in-picture and chroma key?
Yes. The manual describes PIP and keying for overlays. It also states that cut and fade switching cannot be used while PIP is enabled; check the input-combination table for the intended sources.
Which wide output resolution is supported: 7840 or 7680 pixels?
The specification’s feature list says 7840 × 640, while the resolution tables in both documents list 7680 × 640 at 60 Hz. The discrepancy is unresolved; confirm the exact output timing on the supplied unit.
How many scene presets can I save?
Both documents describe four user presets for storing and recalling display settings. Keep a record of the screen and sending-card configuration before changing a working installation.
