Three-Source HDMI 2.1 Switch

This HDMI 2.1 switch routes three separate source devices to a single display input. It supports full-spec 48Gbps bandwidth for uncompressed 8K@60Hz and 4K@120Hz video signals. The unit handles Dolby Vision, HDR10, HLG and Dolby audio pass-through with HDCP 2.3 compliance. It is built for users who need to connect multiple modern consoles or streamers to one high-performance screen.

Sustained High-Bandwidth Operation

The switch maintains the full 48Gbps link during extended gaming or playback sessions without compression artefacts. Gold-plated connectors reduce signal attenuation and EMI interference across continuous use. Bus-powered operation draws energy from the source devices, so performance stays stable without an external adapter. Auto-switching detects a newly powered source and changes the active channel instantly.

Pre-Installation Checks

Verify that your display offers at least one HDMI 2.1 input capable of 48Gbps throughput. Confirm each source device outputs 8K@60Hz or 4K@120Hz over HDMI 2.1 to match the switch rating. Ensure the combined cable runs stay within the 10-metre practical limit for ultra-high-speed HDMI cables. Check that your devices support HDCP 2.3 for protected content playback.

Questions about this item

How much heat or fan noise does the 48Gbps HDMI 2.1 switch produce when running all day?

The bus-powered HDMI 2.1 switch has no fan and draws minimal power, so it stays cool and silent during continuous 8K@60Hz or 4K@120Hz operation.

What cables or power adapters must I already own to connect three sources to one display with this switch?

You need three HDMI 2.1 cables for the sources and one HDMI 2.1 cable for the display; the switch is bus-powered so no separate power adapter is required.

Will the auto-switch and IR remote work reliably with an older 1080p projector or soundbar that only supports HDCP 1.4?

The switch passes HDCP 2.3 and is backward-compatible, so legacy 1080p gear will display correctly, though protected 4K streams may require HDCP 2.3 on the sink device.
