HD-VP1640A Four-Window LED Video Processor
The Huidu HD-VP1640A integrates video processing and LED sending through 16 Gigabit Ethernet outputs. It supports four display windows with flexible layouts and a maximum total load of 10.4 million pixels. Eight scene presets store arrangements for recall.
Input Configuration Choices
DP and Type-C inputs share use: they cannot operate simultaneously. The listed configuration also includes one HDMI 2.0 input, two HDMI 1.4 inputs and two DVI inputs. Optional configurations replace one HDMI 1.4 input with a projection input, or one DVI input with SDI input and loop output. Confirm the required option set before ordering.

Planning the Installation
Use the pixel limit together with the separate width and height limits when sizing the LED screen. The maximum dimensions do not describe a 16000 × 4000 full canvas. For wireless use, distinguish standard Wi-Fi control from the projection input configuration required for the intended source.
