3-Port 8K HDMI 2.1 KVM Switch

The YINGHUA 3x1 switch connects three HDMI 2.1 sources to a single display. It supports 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth. Gamers and home-theatre users can toggle between consoles, PCs or streamers without swapping cables.

Upgrade from manual cable swapping

Moving to this unit is worthwhile when sources and the display both run HDMI 2.1 and certified Ultra High Speed cables are used. Without HDMI 2.1 on both ends the 8K 60 Hz and 4K 120 Hz modes cannot be realised.

Push-button or IR remote switching

The switch is powered from the HDMI lines and works immediately. Common issues arise when non-certified cables limit bandwidth or when one source lacks HDMI 2.1, causing the link to fall back to lower resolutions.

Questions about this item

What HDMI cable length and gauge does the YINGHUA 8K 3x1 switch support for reliable 48 Gbps transmission?

The switch works with standard HDMI 2.1 cables up to 2 metres long and AWG24 gauge to maintain the full 48 Gbps bandwidth for 8K@60 Hz or 4K@120 Hz signals.

How do I switch between the three HDMI inputs on the YINGHUA 8K 3x1 switch, and what is the common mistake to avoid?

Press the easy-click button on the unit or use the included IR remote; the common mistake is forgetting that both the source device and the display must be HDMI 2.1 compliant and connected with certified Ultra High Speed cables to achieve 8K@60 Hz or 4K@120 Hz.

When should I replace the HDMI cables used with the YINGHUA 8K 3x1 switch to keep 8K@60 Hz performance?

Replace any cable that is longer than 2 metres, heavier than AWG24, or not labelled HDMI 2.1 Ultra High Speed, because only certified 2-metre AWG24 cables are specified to sustain the 48 Gbps link required for 8K@60 Hz.
