HD-T902x1 four-port LED sending box
The Huidu HD-T902x1 sends synchronous DVI video to Huidu R-series receiving cards through four Gigabit outputs. It provides one DVI input, one USB-B configuration connection and one stereo audio input, with support for multiple units in a spliced display.
Loading depends on the source setup
The V1.0 specification lists 2.3 million pixels with a direct computer connection at 1920 × 1200, 60 Hz. With a video processor, it lists 2.6 million pixels at 2048 × 1280, 60 Hz. The maximum width and height are separate limits and must be checked against the selected loading mode.
HDSet provides screen configuration through USB-B. The enclosure includes an AC-to-5 V DC transformer and accepts 110–220 V AC. Audio input can be sent over the network to a compatible multifunction card for output.

The linked V1.0 document differs in its internal DC minimum, playback-software names and audio row labels. The external mains rating and the configuration-dependent loading figures are shown separately to avoid confusing these functions.

Frequently asked questions
Does the HD-T902x1 always support 2.6 million pixels?
The specification distinguishes two cases: direct computer connection is listed for 2.3 million pixels at 1920 × 1200, 60 Hz; connection through a video processor is listed for 2.6 million pixels at 2048 × 1280, 60 Hz. Match the source setup to the stated loading condition.
Which receiving cards and setup software are supported?
The document identifies Huidu R-series receiving cards and HDSet for configuration. It mentions HDPlayer in the overview and HD Show in the playback-software table, so confirm the appropriate playback software for the specific system.
Can the USB port play video files from a flash drive?
The specification describes USB-B as a configuration interface. Video arrives through DVI for synchronous display; USB-drive media playback is not listed for this model.
How do I get audio output from the LED installation?
The box accepts a 3.5 mm stereo input and transmits audio through the network connection to a multifunction card. A compatible multifunction card is required for audio output. The source document’s audio row labels are inconsistent, so confirm the exact signal path when planning the system.
Can multiple T902x1 boxes drive a larger display?
Yes. The specification supports multiple units for spliced display and unified control. Check each unit’s video source, receiving-card mapping and applicable loading limits before combining them.
