4x2 HDMI Matrix for Multi-Source Setups

This Vszerda matrix switch connects four HDMI sources to two displays simultaneously. It suits offices, classrooms, home theatres and commercial installations that need flexible routing. The unit handles 4K signals at 60 Hz with 18 Gbps bandwidth and HDCP 2.2 compliance. Automatic downscaling converts 4K to 1080P when a connected display cannot accept the higher resolution.

IR Remote and Audio Extraction Expand Control

The bundle includes an IR remote for source switching without front-panel access. Optical and 3.5 mm stereo outputs separate audio from the HDMI stream for amplifiers, soundbars or powered speakers. A 5 V power adapter and user manual complete the package. These accessories let operators route video to screens while sending sound to a dedicated audio system.

HDMI 2.0b Bandwidth and Downscaling Limits

The switch operates within the HDMI 2.0b specification at 600 MHz maximum bandwidth. Only 4K sources are automatically reduced to 1080P; other resolutions pass through unchanged. Deep-colour support covers 8, 10 and 12 bit formats. The two outputs mirror the selected input rather than showing independent sources, so simultaneous different content on each screen is not possible.

Questions about this item

Does the 5V power adapter or any internal component need periodic replacement?

The unit ships with a 5V power adapter and has no user-serviceable parts; if the adapter fails it can be swapped for an equivalent 5V supply.

What bandwidth ceiling limits sustained 4K 60 Hz throughput on the HDMI 2.0b paths?

The matrix is rated for 18 Gbps and 600 MHz maximum bandwidth, which is the hard limit for continuous 4K 60 Hz 8/10/12-bit signals.

How much heat or fan noise does the switcher produce when running all day?

The device has no fan and draws only 5V power, so it runs silently with minimal warmth during extended operation.
