M50B-D player for local and networked LED signs
The Xixun M50B-D is a standalone LAN player box with Android-based program playback. Its LED output serves up to 650,000 pixels, while separate LAN, Wi-Fi and USB communication options support content publishing and display management.
Choose the optional cellular and sensor configuration for the installation. Standard loading limits, the separately stated extended-width mode and video decoding capability are different specifications and should be checked individually.

Frequently asked questions
What is the LED loading limit of the M50B-D?
The specification lists 650,000 pixels on one Ethernet display output, with standard maximum width and height of 1,920 pixels each. These are separate dimension limits and do not mean that a 1,920 × 1,920 screen is supported.
Can the M50B-D control a 7,680-pixel-wide screen?
The PDF includes a separate extended-width statement of 7,680 pixels under a “discount” condition, but it does not define that mode or its reduced loading. Confirm the intended resolution and configuration before relying on this value.
Are the two network connections interchangeable?
No. The interface table identifies a Gigabit display output and a separate 100 Mbit/s LAN input. Use each port for its stated purpose.
Does every M50B-D include 4G and automatic brightness?
The base M50B-D is listed without 4G; a cellular modem is optional and region-dependent. Automatic brightness requires a matching external brightness sensor. Confirm both options when selecting the configuration.
How do I publish and schedule content?
The specification lists LedOK Express for PC, LedOK Kit for mobile devices and local web publishing. Playlists, scheduled switching, volume and brightness can be managed through the control system. USB program import and playback are also supported.
