HD-VP1240A four-window LED controller
The Huidu HD-VP1240A combines video processing and 12 Gigabit LED outputs for screens up to 7.8 million pixels. Four-window layouts and eight scene presets support multi-source display setups, while standard Wi-Fi enables mobile app control.
4K input selection and control
HDMI1 supports 4K at 60 Hz through HDMI 2.0. HDMI2 and HDMI3 support 4K at 30 Hz through HDMI 1.4. DP and Type-C each support up to 3840 × 2160 at 60 Hz, but share an input selection and cannot be used simultaneously. Two DVI inputs provide additional 1080p source connections.
Use front-panel controls for window selection, brightness, scene recall, freeze and black screen. USB-B connects a computer for configuration, and RS232 connects central control equipment. The microphone interface is reserved in the specification and is not presented as an active voice-control feature.

Values follow the linked HD-VP1240A V1.1 specification. Its detailed HDMI table mentions an HDMI3/projection choice, while its main feature list describes two HDMI 1.4 inputs. Confirm this configuration detail for the supplied unit; Wi-Fi app control alone does not establish projection availability.

Frequently asked questions
Which VP1240A inputs accept 4K60 video?
HDMI1 uses HDMI 2.0 and accepts up to 3840 × 2160 at 60 Hz. DP and Type-C are also listed for that limit. HDMI2 and HDMI3 use HDMI 1.4 and are limited to 3840 × 2160 at 30 Hz.
Can I use DP and Type-C simultaneously?
No. The specification says they cannot be used at the same time. DP is the default selection; Type-C must be enabled in Advanced Settings. Plan sources around this shared selection.
Does standard Wi-Fi mean wireless projection is included?
Standard Wi-Fi is explicitly described for mobile app control. The detailed HDMI table separately says to choose between HDMI3 and projection, without fully defining that projection configuration. Confirm the supplied version and projection capability before ordering.
How many pixels and windows can it control?
The VP1240A supports 7.8 million pixels across 12 outputs, at 650,000 pixels per port, and four-window layouts. Its maximum width of 16,000 pixels and height of 4,000 pixels are separate limits within the total loading capacity.
Can the USB port play media files?
The linked VP1240A V1.1 specification describes USB-B as a computer configuration interface. It does not list USB-drive media playback, so that feature should not be assumed from the USB connection.
