The StarTech.com ST12MHDLAN4K is an HDMI-over-IP extender kit that sends 4K video at 30 Hz over Gigabit LAN for video walls, digital signage, and other multi-display installations; it suits AV integrators and businesses that want to use existing network infrastructure for video distribution.
Recommended For
- Digital-signage teams in retail, hospitality, or corporate spaces that need to send one HDMI source to displays across an existing Gigabit LAN and manage routing from the control app.
- AV integrators building video walls or multi-display installations who want to add compatible receivers and route sources across a network rather than rely on a fixed HDMI splitter.
- IT or facilities teams extending a 4K30 presentation or signage feed to a remote display, including point-to-point runs up to 100 m over Cat5e or better cabling.
- Installers who can coordinate with network staff to provide sufficient bandwidth and configure IGMP snooping for a multi-device AV-over-IP deployment.
