What video resolutions does the SW-4X1HDUSBC support?

HDMI inputs support up to 8K@60Hz 4:2:0 12-bit and 4K@120Hz 4:4:4 12-bit. The USB-C input supports up to 8K@30Hz 4:2:2 10-bit and 4K@120Hz 4:2:2 10-bit.

What is the maximum video bandwidth?

HDMI inputs support up to 48Gbps FRL and 18Gbps TMDS. The USB-C input supports up to 32Gbps with DP 1.4 compliance.

Does the USB-C input support DP Alt Mode?

Yes. The USB-C input is DP 1.4 compliant and supports video bandwidth up to 32Gbps via DisplayPort Alternate Mode.

What EDID modes are available?

Eight EDID presets via 3-pin DIP switch: copy sink EDID (default), 4K@60Hz 4:4:4 2ch PCM, FRL 12G 8K HDR with 2ch/5.1ch/7.1ch audio options, and FRL 10G 8K HDR with 2ch/5.1ch/7.1ch audio options.

What power supply is required?

The included 5V/1A DC power supply (AC 100-240V input). The unit consumes 2.25W maximum.

What are the dimensions and mounting options?

145mm (W) x 68mm (D) x 18mm (H), weighing 258g. The ultrathin metal housing can sit on a desk, mount behind a display with Velcro, or tuck under a conference table. It is not rack-mountable.

No video output — what should I check?

Verify the power LED is on (red). Check that the correct input is selected (green LED on IN 1-4). Use Ultra High Speed HDMI cables for 8K (2m max). Try changing the EDID DIP switch to match your display resolution.

USB-C source not detected?

Ensure the USB-C cable supports DP Alt Mode. Not all USB-C cables carry video — use a cable rated for DisplayPort or Thunderbolt. Check that the source device has DP Alt Mode enabled.

Why choose this over a standard 4x1 HDMI switch with a USB-C adapter?

The native USB-C input eliminates adapter dependency — no signal degradation, no lost dongles, no extra failure points. It supports up to 32Gbps DP 1.4 video natively without conversion overhead.

What certifications does it have?

CE, FCC, and UL certified. The universal power supply (AC 100-240V 50/60Hz) supports worldwide deployment.
