HD-VP1240 four-window LED video processor
The Huidu HD-VP1240 combines video processing and 12-port LED sending for displays up to 7.8 million pixels. It supports four live windows with POP layouts, two DP inputs, two HDMI inputs, DVI and an EXT input configured for the supplied unit.
Source selection and cabinet setup
Use DP 1.2 for sources up to 4K at 60 Hz, or HDMI 1.4 for up to 4K at 30 Hz. Preset and customized input resolution settings are available for DVI, HDMI and DP. Select source audio from HDMI, DP or the analog input for the 3.5 mm output.
Front-panel navigation and connection settings support local cabinet setup. HDSet over USB-B provides computer configuration, and RS232 connects central control equipment. Automatic parameter storage retains settings after power-off; up to eight user templates provide scene recall. Brightness, freeze, black screen and key lock have front-panel controls.

Frequently asked questions
Does the VP1240 support four simultaneous windows?
Yes. The V2.0 overview and feature list specify four live windows with POP layout, and the front panel has WIN1 through WIN4 selection controls. Input count, window layout and LED output load should be planned separately.
Are all HDMI and DP inputs capable of 4K60?
No. Both DP 1.2 inputs support up to 3840 × 2160 at 60 Hz. The two HDMI 1.4 inputs support up to 3840 × 2160 at 30 Hz.
Can I set up cabinet connections without a computer?
Yes. The specification describes front-panel navigation and connection settings for cabinet parameters. USB-B with HDSet is also available for sending-card and receiving-card configuration and upgrades.
Is Wi-Fi app control available on this version?
The linked V2.0 document marks mobile app functions as developing. Confirm hardware, firmware and app availability before relying on wireless control. Front-panel, USB/HDSet and RS232 controls are documented.
How many LED pixels and presets does it support?
The VP1240 supports 7.8 million pixels across 12 Gigabit outputs and up to eight user templates. Maximum width of 16,000 pixels and height of 3,840 pixels are independent limits; a screen must also fit the total pixel capacity.
