How switching and multi-display behavior works
Only one source is shown at a time. Changing inputs causes a normal HDMI re-handshake. The switch does not split one source across several displays.
Control: Manual button or included IR remote; automatic switching is explicitly not supported.
Never assume: a product advertised as “bidirectional,” “splitter” or “matrix” behaves like another topology. Follow the source/output map above.

Setup and usability guidance
Best first test: one source, one short cable path, one display and 1080p60. Expand only after this baseline works.
- Step 1: Connect the USB power cable to a stable 5V USB source; a wall adapter is not supplied.
- Step 2: Connect up to three HDMI sources to the numbered inputs.
- Step 3: Connect the single HDMI output to the display.
- Step 4: Place the IR receiver path where the remote can reach it and fit a compatible battery separately.
- Step 5: Select sources manually or by remote; do not expect auto-switching.
- Step 6: Begin at 1080p60 and move to 4K60 only when both HDMI cable legs and endpoints support it.

What this product does
- Follows this path: Three HDMI source inputs → manual or IR source selection → one HDMI display output.
- Supports its ceiling: Up to 4K60; listing also states 1440p120 and 1080p240 with a fully compatible path.
- Uses these ports: 3 × HDMI Type-A female → 1 × HDMI Type-A female.
- Handles control this way: Manual button or included IR remote; automatic switching is explicitly not supported.
- Passes compatible audio: Compatible HDMI audio; the listing names PCM 2.0, Dolby 2.0/5.1 and DTS 5.1/7.1. It does not establish every Dolby/DTS variant or eARC.
What this product does not do
- No automatic switching despite the old keyword-stuffed title
- One HDMI output only
- Power adapter and remote batteries are not included
- Not a splitter, capture card or KVM
- No eARC or variable-refresh guarantee is established

Warnings and limitations
- Power: USB-C power input; USB-A-to-USB-C power cable included, wall adapter not included.
- Display negotiation: mixed displays can force a lower common mode or create a blank screen.
- Protected content: HDCP must be supported end to end; the device cannot bypass protection.
- Heat and moisture: indoor use only; keep dry, ventilated and away from direct heat.
- Cables: For 4K60 the listing recommends no more than 10ft (about 3m) on both the input and output HDMI cable. The 33ft figure applies to IR remote range, not HDMI cable length.
