HD-VP1620 dual-window LED video processor
The Huidu HD-VP1620 combines video processing and LED sending through 16 Gigabit outputs. It supports up to 10.4 million LED pixels and two live video windows with picture-in-picture (PIP) or picture-outside-picture (POP) layouts.
Cabinet setup and scene recall
Front-panel navigation and connection settings let operators configure cabinet connections locally. HDSet through USB-B provides computer-based sending-card and receiving-card setup. Up to eight user templates can store settings for recall, while automatic parameter storage retains adjustments after power-off.
Input choices include HDMI, DP, DVI, VGA and the configured EXT interface. Audio can be selected from HDMI, DP or the analog input. Brightness, freeze, black-screen and key-lock shortcuts are available on the front panel.

Frequently asked questions
Does the HD-VP1620 support picture-in-picture?
Yes. It supports two live video windows with PIP and POP layouts. The front panel has WIN1 and WIN2 controls and a PXP shortcut for the dual-picture layout menu.
Can I configure cabinet connections without a computer?
The specification describes a front-panel connection-setting function for cabinet connection parameters and a navigation setup function. USB-B and HDSet are also available for sending-card and receiving-card configuration.
Which input should I use for a 4K source?
The document lists DP 1.2 up to 3840 × 2160 at 60 Hz. It also lists that resolution for HDMI alongside “HDMI 1.3 backward compatible” wording. Confirm the actual HDMI signal support and firmware for the supplied unit before relying on a 4K60 HDMI source.
Is mobile app control ready to use?
The linked V1.0 specification marks the Wi-Fi mobile app functions as developing. Do not assume they are enabled on every unit; confirm current hardware, firmware and app support. Front-panel and USB/HDSet controls are documented.
How much LED screen capacity is available?
The controller supports 10.4 million pixels through 16 outputs, with 650,000 pixels per port. Screen width and height limits, and each port’s 2048-pixel width or height limit, must be checked separately alongside the pixel totals.
