Huidu HD-VP1640A LED Video Processor Overview
The Huidu HD-VP1640A, also referred to as VP1640A, is a 2-in-1 LED video processor that combines video processing and LED sending in one unit. Its 16 Gigabit Ethernet outputs connect to compatible receiving cards and support an LED display load of up to 10.4 million pixels. Four-screen layouts let you arrange several sources for presentations, events and live display applications.
Designed for synchronous playback in conference rooms, hotels, shopping malls, exhibitions and studios, the VP1640A accepts multiple video sources and includes Wi-Fi for mobile app control. Check your screen resolution, source connections and required optional modules before selecting a configuration.
HD-VP1640A Technical Specifications
| Specification | Details |
|---|---|
| Product type | 2-in-1 LED video processor with integrated sending function |
| LED outputs | 16 Gigabit Ethernet ports for compatible receiving cards |
| Maximum loading capacity | 10.4 million pixels in total |
| Maximum screen dimensions | Up to 16,000 pixels wide or 4,000 pixels high, subject to the total pixel capacity and output configuration |
| Video input capability | Up to 4K@60Hz on supported inputs; not every connector supports the same format |
| Standard video connections | 1 × DP / 1 × Type-C shared input, 1 × HDMI 2.0, 2 × HDMI 1.4 and 2 × DVI; DP and Type-C cannot be used simultaneously |
| Screen layout | Up to four screens with flexible positioning; picture-in-picture and picture-out-of-picture layouts |
| Scene presets | 8 presets for storing and recalling display arrangements |
| Wireless control | Standard Wi-Fi for mobile app operation |
| Audio | 3.5 mm TRS stereo input and output, plus HDMI/DP audio input |
Screen-sizing note: The width and height limits are separate limits, not a supported 16,000 × 4,000 canvas. Calculate width × height and keep the result within 10.4 million pixels, then check the receiving-card layout and port allocation. A 4K input describes the source signal; the actual LED canvas must also satisfy the output limits.
Video Inputs and Optional Configurations
The standard connections include HDMI 2.0, HDMI 1.4, DVI and a shared DP/Type-C input. Select DP or Type-C for that shared channel; they are not two simultaneous independent sources. Match each source device to the resolution and refresh rate supported by its chosen connector.
- Wireless projection: the optional projection configuration supports mobile phone or tablet screen sharing and changes the available HDMI 1.4 input arrangement.
- SDI input and loop output: an optional configuration replaces one DVI input with SDI and provides SDI LOOP. Confirm this configuration if your source requires SDI.
- USB media playback: optional USB hardware supports video and image playback from a USB drive.
- 4G remote unlocking: available as an optional function; confirm the required module and service arrangement before ordering.
Wi-Fi app control and wireless screen projection are different functions. Standard Wi-Fi control does not by itself confirm that projection, USB or 4G options are installed.
Four-Screen Layouts and Everyday Control
Use the four-screen display function to arrange presentation content, camera feeds or other connected sources. Eight scene presets help recall recurring layouts. Mobile app control supports operations such as source switching, screen settings, brightness and volume adjustment, and one-click black screen.
The processor also supports brightness adjustment, a key lock and internal temperature monitoring. These functions help operators manage the display during everyday use and live presentations.
Connection Diagram

Planning Your LED Display System
- Record the LED screen width and height in pixels, then calculate its total pixel count.
- List the source devices, connectors, resolutions and refresh rates you need to use.
- Confirm receiving-card compatibility and the load distribution across the 16 Ethernet outputs.
- Specify any required projection, SDI, USB playback or 4G remote-unlocking options before purchase.

Frequently Asked Questions
What is the maximum load of the HD-VP1640A?
The maximum total load is 10.4 million pixels across 16 Gigabit Ethernet outputs. Screen dimensions, receiving-card loading and port allocation must also be checked.
Does the VP1640A support 4K@60Hz input?
Yes, on supported input interfaces. Check the selected port’s signal limits; 4K input support does not mean every port accepts 4K@60Hz.
Can DP and Type-C be used at the same time?
No. DP and Type-C share an input channel, so only one of the two can be used at a time.
Are USB playback and SDI included as standard?
No. USB playback and SDI are configuration-dependent options. Confirm the installed hardware before ordering, along with any wireless projection or 4G requirement.
