Warrky WARRKY-AV-H03 HDMI switch 2x1 4K 60Hz 3.3ft cable

Switching between two HDMI sources

This bidirectional HDMI switch connects two sources to one display or one source to two displays with a simple button press. The 3.3ft fixed braided cable eliminates the need for an extra lead and reduces loose-connection faults. It supports 4K at 60Hz and 2K at 144Hz with HDCP 2.2 compliance for protected streaming content. Audio pass-through handles uncompressed 7.1, 5.1 or 2-channel formats including Dolby Atmos and DTS.

Sustained thermal performance under load

The aluminum alloy shell dissipates heat efficiently during continuous operation. The supplier notes the casing remains at 92°F after 12 hours of use, indicating stable temperatures for long viewing or gaming sessions. An industry-leading IC chip maintains 10.2Gbps bandwidth without signal degradation over the AWG26 HDMI 2.0 standard wire. Gold-plated connectors resist corrosion and interference better than nickel alternatives.

Installation constraints and common issues

The fixed 3.3ft pigtail cable limits placement flexibility; the source or display must sit within that reach of the switch body. Only one of the two connected displays operates at a time in display-switching mode, so simultaneous output is not possible. The compact 2.07 x 1.77 x 0.51 in dimensions fit tight spaces but require access to the button for manual switching. No external power adapter is needed for typical HDMI sources.
