HD-T16 4K synchronous LED sending box
The Huidu HD-T16 accepts HDMI 2.0 or DP 1.4 video and sends display data through 16 Gigabit outputs. It supports up to 8.84 million pixels and 4096 × 2160 at 60 Hz input, with point-to-point display for synchronous LED systems.
Wide-screen timings and preview monitoring
For extra-wide or tall layouts, the specification lists 8192 × 1080 at 60 Hz and 1080 × 8192 at 60 Hz custom input examples. The overall pixel capacity remains separate from the maximum width and height, so check the full source timing and receiving-card mapping.
An HDMI OUT connector previews the displayed content. Front-panel buttons select HDMI or DP, freeze the picture or switch to black. Standard Wi-Fi supports PC software wireless control; USB-B and RS232 provide additional setup and control connections.

Frequently asked questions
Can both HDMI and DP accept 4K60 video?
Yes. The V1.0 specification lists HDMI 2.0 and DP 1.4 inputs up to 4096 × 2160 at 60 Hz. The front panel selects which input is displayed.
Does sixteen-port capacity mean the total load is 10.4 million pixels?
No. Although each port is listed for 650,000 pixels, the T16 has a separate total limit of 8.84 million pixels. Screen mapping must satisfy the total limit, the per-port limits and the dimension limits together.
Can the T16 handle an extra-wide LED screen?
The specification lists custom input examples of 8192 × 1080 at 60 Hz and 1080 × 8192 at 60 Hz. These are specific timings; a maximum width and maximum height cannot be combined into an 8192 × 8192 screen.
What is the HDMI OUT connector used for?
HDMI OUT monitors the content playing on the display. The LED receiving cards connect to the numbered Gigabit outputs, while HDMI OUT connects to a preview monitor.
How are wireless control and audio handled?
Standard Wi-Fi supports wireless control from PC software. For audio, the 3.5 mm input sends audio through LED port 1 to a compatible multifunction card. Infrared remote control is optional.
