Poster screen playback and setup
Use an independent playback layout for separate adverts, or configure HDMI-connected posters as one larger picture. The manual also describes creative screen arrangements and synchronized playback on separate screens. Confirm the pixel layout and cascade wiring before publishing programs.
USB can update or play programs and expand storage. Supported content includes video, pictures, GIF animation, text, WPS documents, clocks and schedules. Network access enables remote management; sensors and GPS require the relevant external hardware.
Check board mounting, power supply and enclosure protection. The controller must be protected from water; the document does not assign it an outdoor waterproof rating.

Frequently asked questions
Can the HD-B6L join several LED poster screens into one image?
Yes. HDMI input/output supports cascade splicing, with up to 10 levels documented. The specified combined loading limit is 2.6 million pixels across multiple B6L cards; confirm the screen arrangement and receiving-card configuration.
Can I switch between live HDMI and stored advertising content?
The B6L supports synchronous HDMI playback, asynchronous program playback and mixed playback, including picture-in-picture. Choose the required mode during configuration.
Does 4K video playback mean a 4K LED output?
No. Video decoding and window playback are separate from the LED loading limit. A single B6L is specified for 1.3 million LED pixels.
Is 4G included, and which app controls the B6L?
Wi-Fi is standard and LedArt provides mobile control. HDPlayer handles PC configuration and publishing. Remote cellular access requires the optional 4G module; XiaoHui Cloud supports Internet management.
Can both audio connections be used immediately?
The 3.5 mm TRS output is documented as a standard two-channel output. Although the feature list also mentions 4-pin audio, the interface description marks that connection reserved; confirm its availability for the supplied hardware.
