HD-VP820 all-in-one processor for dual-window LED displays
The Huidu HD-VP820 integrates video processing and LED sending with eight Gigabit Ethernet outputs and up to 5.2 million pixels of loading. It supports two live windows and accepts digital and analog sources for stage, rental, studio and fixed-screen applications.
Screen setup and live operation
Use front-panel navigation to set cabinet connections, select input sources and adjust brightness. PIP/POP layouts and eight scene templates support repeated display arrangements. Parameters are saved automatically, and key lock, black screen and freeze controls are available during operation.
The HDMI monitor output provides a 1080p view on an external display. USB Type-B connects to a computer running HDSet for sending/receiving-card configuration and upgrades; it is not specified as a USB media-playback port.

Frequently asked questions
Can the HD-VP820 display two sources together?
Yes. It supports two live windows, including picture-in-picture and picture-outside-picture layouts, with eight scene templates for recall.
Which input should I check for 4K at 60 Hz?
The DP 1.2 input is specified up to 3840 × 2160 at 60 Hz. The HDMI table also lists that resolution but labels the interface HDMI 1.3, so verify HDMI capability with the supplied hardware before relying on that combination.
Is the HDMI monitor output a 4K output?
No. The monitor connection is specified at 1920 × 1080 at 60 Hz for an external display. It is separate from both the input resolution and the LED output loading.
Can I use a phone app to configure the VP820?
The document lists Wi-Fi but marks mobile app functions as developing. Confirm current support for the supplied firmware. Front-panel setup and USB Type-B configuration through HDSet are documented workflows.
What does the eight-port loading limit mean?
The processor is rated for 5.2 million total pixels, with 650,000 pixels per Gigabit port. The maximum screen width and height are separate layout limits, not a supported full 8,000 × 3,840 canvas.
