The Linsn L4 supports synchronous HDMI display and asynchronous program playback. The manufacturer’s V3.1 specification identifies two network ports: one output and one backup. The older listing also mentions HDMI output and 4G, which are not confirmed in that specification; check the supplied hardware before relying on either function.

Yes. It supports HDMI synchronous input and program playback through USB flash drive or LAN.
Can both network ports be treated as separate display outputs?
The V3.1 specification lists one display output and one backup port. Confirm the usable loading for the intended arrangement.
