Huidu HD-H6 six-output LED multimedia player
The HD-H6 brings local program creation, media playback and live HDMI sources into a six-output LED control system. Its 3.93-million-pixel capacity suits installations that need both scheduled content and interactive presentation, including meeting rooms, exhibition spaces and hotel lobbies.

Live sources, local playback and control
Choose synchronous HDMI input or asynchronous local playback, with picture-in-picture and cascade functions described in the specification. Dual Wi-Fi supports simultaneous hotspot and wireless network access. Bluetooth connects supported peripherals and enables voice-control functions.
Wireless projection activation, USB casting hardware, optical modules, fiber and regional 4G/5G modules are optional. The relay connector is reserved. Both RS232 and RS485 connectors are shown, but the feature list describes central control as RS232 or RS485; confirm simultaneous-use requirements.
The video playback combinations are alternatives, and codec-specific limits still apply. Confirm the module and firmware configuration for optical duplication. Keep the IP20 unit protected from water.


HD-H6 frequently asked questions
What is the HD-H6 maximum LED loading capacity?
The H6 provides six Gigabit LED outputs with a total capacity of 3.93 million pixels. Maximum width is 65,536 pixels or maximum height is 8,192 pixels; neither dimension overrides the total pixel limit.
Can H6 create and play content without a computer?
Yes. The specification describes local program editing, creation and playback, plus third-party information-publishing apps. It lists Android 11.0, 4 GB RAM and 64 GB internal storage.
What HDMI input resolutions does H6 accept?
HDMI IN supports up to 3840 × 2160 at 30 Hz and recommends 1920 × 1080 at 60 Hz. The separate HDMI LOOP input supports up to 2048 × 1152 at 60 Hz. HDMI OUT is used for cascading or monitoring.
Are wireless casting and 4G/5G included?
The optional-accessory list includes a wireless-projection activation code, USB casting transmitter and region-specific 4G/5G module. The casting transmitter requires device activation. Confirm the selected package rather than assuming these options are enabled.
How does H6 optical cascading work?
SFP IN accepts a cascade signal and SFP OUT passes the signal to the next unit. FT08 duplication requires special firmware. Optical modules and fiber are optional, and the document does not specify a numeric maximum fiber distance.
