8K HDR HDMI True Matrix 4x2 KVM Switch

This 4x2 HDMI matrix switch routes four sources to two displays while extracting audio via optical, RCA and ARC outputs. It supports video resolutions up to 4320p at 50 or 60 Hz with HDR and Dolby Vision, plus 2160p at up to 120 Hz for high-refresh gaming. Transmission bandwidth reaches 40 Gbps over HDMI 2.1, handling deep colour up to 16-bit at 4K and 10-bit at 8K. The unit includes a remote control and a 12 V 1.5 A power adapter.

Installation and common issues

Connect all HDMI cables before applying power and use standard-certified cables to avoid signal loss. The manufacturer advises connecting an 8K display to the OUT B port because OUT A is limited to 8K at 60 Hz or 4K at 120 Hz. Input cable runs should not exceed 3 metres for 8K, 5 metres for 4K or 10 metres for 1080p, while output runs allow 12 metres at 1080p. IR control works up to 5 metres; ensure the sensor has line of sight.

Ideal users and limitations

Suits installers and enthusiasts who need to distribute four HDMI 2.1 sources across two screens with multi-channel audio extraction. Not suited for buyers who require more than two simultaneous outputs or who need HDMI 2.1 features beyond the specified 40 Gbps bandwidth. Users without a US-style mains socket will need a local adapter for the included power supply.

Questions about this item

How do I confirm the UTEK 8K matrix is passing 4320p@60Hz HDR to both displays after setup?

Connect an 8K source to any of the four HDMI inputs, link OUTB to the primary 8K display and OUTA to the second display, then verify each screen reports 4320p@60Hz with HDR or Dolby Vision active in its on-screen information menu.

Which cables and accessories are included in the box versus what I must purchase separately?

The package supplies the 4x2 matrix unit, a printed manual, a remote controller (battery not included), and a 12V/1.5A power adaptor; you must provide up to four HDMI source cables and two HDMI display cables rated for the required resolution and bandwidth.

Which output should I use for my 8K TV and which for a 4K@120Hz monitor to get the best performance?

Connect the 8K TV to OUTB for full 4320p@60Hz support; use OUTA for the 4K@120Hz monitor, as OUTA is limited to 4320p@60Hz or 2160p@120Hz maximum.
