HD-VP820 Video Processing and LED Sending
The Huidu HD-VP820 is an all-in-one LED video processor with eight Gigabit Ethernet outputs. It supports two-picture PIP and POP layouts, source switching and scene-preset recall. Five digital and analog input channels provide connections for different video sources.
Setup and Monitoring
Navigation Settings guide initial setup, and panel buttons can set cabinet connection parameters without a computer. The USB Type-B port connects to HDSet software for sending-card and receiving-card configuration and upgrades. An HDMI monitor output provides a synchronous 1920 × 1080 at 60 Hz feed for an external LCD.

Input and Loading Notes
The supplied specification lists both HDMI 1.3 backward compatibility and a 3840 × 2160 at 60 Hz HDMI input limit. These original entries are retained here; confirm the supported HDMI source mode for the unit before planning a 4K60 connection. The DP input is separately listed up to 3840 × 2160 at 60 Hz.
Maximum width and height are separate limits. Apply the total pixel limit and each Ethernet port’s loading limit when laying out the screen. The Wi-Fi mobile app is marked as under development in the supplied document, so confirm availability before relying on it.
