Connect 16 4K UHD source devices to 16 4K UHD screens
Matrix Switches are premium solutions for distributing content from multiple source devices to multiple displays. The Lindy 16x16 HDMI® 4K60 Matrix supports HDMI® 2.0b 18G signals, allowing for the transmission of clear 4K Ultra HD 60Hz resolutions. Additional support for High Dynamic Range ensures video content is displayed with enhanced brightness, greater contrasts and a much wider colour gamut, perfect for digital signage displays in retail, creating informational multi-display setups in education, or distributing content in commercial installations such as cinemas. HDCP 2.2 support ensures there are no issues with a variety of 4K content when connected to source devices including set top boxes, Blu-Ray players and 4K HDR media players.
As well as HDMI® audio pass-through, individual Coax ports allow for a separate connection of digital speaker systems and amplifiers, creating immersive audio experiences to compliment the video content. The Audio Return Channel (ARC) feature allows audio to be sent from a TV to an audio system or soundbar over the same HDMI® cable that is used to send video to the TV. This eliminates the need for a separate audio cable and simplifies the setup process.
The Matrix also features a downscale function for each output port from 4K to Full HD, making installations with older displays hassle free while always ensuring the viewer receives the optimum picture from their display.
This Matrix can be easily controlled via push button switching on the unit, while the included remote control and IR extension also allows the user to have better control over multiple videos and displays, great for trade shows, training presentations or sales demonstrations.

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.
