The StarTech ST12MHDLAN4K in depth

Scalable HDMI over your network

The ST12MHDLAN4K kit sends HDMI video and audio across a standard IP network instead of dedicated splitters and long HDMI runs. Add receivers for more screens or build a video wall, and control routing centrally from the app.

Network requirements

Your switch or router must support IGMP snooping with it enabled, plus multicast and jumbo frames. Latency at 4K 30Hz is 200ms between transmitter and receiver.
