Connect 9 HDMI® inputs and view on a single HDMI® display
HDMI® Multi-view switches are professional solutions for showing one or more sources of HDMI® content on a single display.
The Lindy HDMI® 4K30 Multi-view Switch is a high performance solution for switching between a single or multiple HDMI® source devices and outputting to a single HDMI® display or projector. As well as standard switching between up to 9 devices, content can be viewed from all connected devices in a variety of layouts in the display, ideal for a wide range of scenarios.
These scenarios include the connection of two source devices in split screen layouts, which provide a useful layout for small scale CCTV or supporting content in retail stores, to the connection of 9 inputs for use in traffic monitoring or TV broadcasting facilities.
Resolutions up to 4K UHD 3840x2160@30Hz are supported providing an optimum viewing experience in detailed digital signage, security or broadcasting installations.
Switching can be easily controlled by the user via the push button on the main unit, or using the IR remote control, which also allows for hassle free switching between layouts modes. The switch also allows for output resolution scaling to ensure a consistent image quality within a setup, as well as independent audio switching from the connected HDMI® devices, great for adding music or alternative commentary to video content from a separate HDMI® source. Both features can also be easily controlled using the IR remote. RS-232 serial switching can also be used for control via a PC connection.
Seamless switching guarantees there is almost no downtime when alternating between connections, ensuring there is no interruption of content, meaning nothing is missed by the viewer when experiencing live sports or breaking news headlines.

Protect Critical SFP Ports from Tampering, Damage or Unauthorised Access
The Lindy SFP Port Blocker provides a fast, effective way to physically secure unused SFP (Small Form-factor Pluggable) network ports. These compact blockers are ideal for safeguarding fibre infrastructure in sensitive IT environments, AV-over-IP setups, and networked installations where access control is essential.
By preventing unauthorised connections, accidental cable insertions or foreign object intrusion, Lindy SFP Port Blockers reduce the risk of port damage and potential downtime. A robust insertion mechanism keeps each blocker firmly in place, with colour-coded keys ensuring only authorised removal. Additional keys and blocker packs are also available.
