2x1 8K HDMI 2.1 Switch

The BZBGEAR BG-8K-HS21 is a compact 2x1 HDMI 2.1 switch designed for users who need to alternate between two source devices on a single display. It handles 8K resolution at 60Hz with 4:4:4 chroma subsampling and 4K at 120Hz for high-fidelity gaming and media playback. The unit supports 48Gbps bandwidth and passes HDR10+, Dolby Vision, and HLG metadata. Its ultra-slim profile fits discreetly into any AV rack or desktop setup.

Replacing Manual Cable Swapping

This switch eliminates the need to physically change HDMI cables when moving between a console, media player, or PC. The jump is worth it when sources output 8K60 or 4K120 signals that require the full 48Gbps bandwidth and HDCP 2.3 compliance. It also preserves VRR, FVA, and ALLM features for variable refresh rate gaming without signal degradation. Users staying at 4K60 or lower with static HDR may not need this bandwidth headroom.

Integration With HDMI 2.1 Sources and Displays

Connect two HDMI Type A sources to the inputs and one display to the output using standard 19-pin cables. The switch draws power from the connected devices and requires no external adapter, freeing a power outlet. It supports LPCM, Dolby TrueHD, DTS-HD Master Audio, and DSD bitstream pass-through for full audio fidelity. Ensure source cables are rated for 48Gbps to maintain 8K60 4:4:4 performance across the link.
