UNITEK V1127A video splitter HDMI 2x HDMI

This bi-directional 4K HDMI 2.0 switch lets you route HDMI signals between two sources and one display or between one source and two displays. It supports up to 4K Ultra‑HD resolution and is backward compatible with earlier HDMI versions. The unit has a solid aluminum‑alloy housing and durable construction to withstand typical operating temperatures and static conditions. For best 4K@60Hz performance use HDMI 2.0 cables up to 3 m (AWG26 or thicker); longer cables reduce the achievable signal specification.

Advantages

The switch offers bi‑directional functionality so it can be used either to select between two input devices for a single screen or to switch a single source between two displays. Signal switching is performed instantly with a front button and an LED indicator shows the active port. Its robust aluminum‑alloy enclosure improves durability and helps protect the electronics from static and temperature extremes. The device is plug‑and‑play and does not require an external power adapter.

How to use

Connect your HDMI sources and displays according to the intended mode: either plug two source devices into the input ports and one display into the output port, or connect one source to the input and two displays to the output ports. Use suitable HDMI2.0 cables following the length and conductor recommendations for desired resolution. Press the front button to switch the active signal; the LED indicator will show which port is active. No additional power connection is necessary.

Recommendations

For reliable 4K@60Hz performance, use HDMI 2.0 cables no longer than 3 m with AWG26 or thicker conductors. If you need longer runs for 4K output, keep cable lengths under 10 m and verify device compatibility.
