Connect and switch between 2 HDMI® source devices and 2 HDMI® displays
A matrix switch is a multi-port solution for distributing content from multiple sources to several displays in a variety of configurations.
The Lindy 2x2 HDMI® 18G Matrix Switch is a premium, compact solution for distributing content from two devices to two displays. Dual HDMI® inputs and outputs provide the ability to switch between 2 separate source devices or 2 connected HDMI® displays, or output video simultaneously.
With support for HDMI® 18G signals, this matrix allows for the transmission of high quality 4K UHD 4096x2160@60Hz resolutions, while additional support for HDR (High Dynamic Range) ensures video content can be viewed with enhanced brightness, greater contrasts and a much wider colour gamut, perfect for high quality residential setups or small scale digital signage installations in retail.
HDCP 2.2 support ensures there are no compatability issues with 4K content when connected to source devices including set top boxes, Blu-Ray players and 4K HDR media players. Simple EDID management via an integrated switch allows the user to control and ensure the optimum resolution based on their connected displays.
As well as HDMI® audio pass-through, a 3.5mm audio port allows for a separate connection of both analogue speaker systems, and optical audio devices such as soundbars and amplifiers, for creating immersive audio experiences to compliment the video on screen.
This matrix can be easily controlled via push button switching on the unit, while the included remote control 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.
