HD-VP1640A four-window LED video processor
The Huidu HD-VP1640A combines video processing and 16-port LED sending for up to 10.4 million pixels. It supports four-window layouts and eight scene presets, with HDMI 2.0, DP and Type-C input paths capable of 4K at 60 Hz under the documented configuration limits.
Select the right input configuration
DP and Type-C share a selection and cannot be used simultaneously. HDMI1 supports 4K60; the HDMI 1.4 inputs support 4K30. HDMI3 and wireless projection are alternative options, as are DVI2 and SDI. Confirm these choices before ordering so the available inputs match the source equipment.
Wi-Fi app control is standard. Wireless screen projection, USB media playback, SDI and 4G-related interfaces depend on the selected version or option. The linked specification distinguishes standard and premium versions, so features shown in one diagram should not be assumed to be included in every unit.
