Bi-Directional HDMI 2.1 Switch

The ESTONE switch routes 48 Gbps signals between two sources and one display, or one source and two displays, with a single button press. It handles 8K at 60 Hz, 4K at 120 Hz, 144 Hz and 165 Hz, plus 1080p at 240 Hz. The aluminium chassis aids heat dissipation and resists fingerprints during frequent use.

Replaces Manual Cable Swapping

This unit removes the need to physically unplug HDMI cables when moving between a console, PC or streaming device. The upgrade is worth it when a display has only one HDMI 2.1 port but multiple 4K high-refresh sources need access. It does not suit users who need two screens active simultaneously, as the splitter mode toggles rather than mirrors.

48 Gbps Bandwidth Headroom

The 48 Gbps link comfortably carries 8K 60 Hz with Dynamic HDR, Dolby Vision, VRR and eARC metadata. It also supports 4K 144 Hz and 1080p 240 Hz chroma 4:4:4 without compression. Headroom runs out if a future 8K 120 Hz source appears, because the 2.1 spec caps the switch at 48 Gbps.

Questions about this item

Does the switch need external power or does it draw power from the HDMI ports?

The bi-directional HDMI 2.1 switch operates without an external power adapter; it draws the small current it needs directly from the connected HDMI sources.

How do I change between the two inputs or the two displays, and what is the common mistake?

Press the button on the aluminium chassis to toggle sources or displays; the mistake is expecting both screens to show an image at the same time — the splitter mode only switches, it does not duplicate.

Will the gold-plated HDMI connectors or the aluminium housing need any upkeep over time?

No routine maintenance is required; the gold-plated contacts resist oxidation and the aluminium shell dissipates heat passively, so the unit runs reliably without cleaning or part replacement.
