Jansicotek OZ8Q3-1 3-port HDMI 2.1 switch

The Jansicotek OZ8Q3-1 is a 3-port HDMI 2.1 video switch that routes three HDMI sources to a single display. It supports 8K resolution at 60 Hz, 4K at 120 Hz, and 1080p at 240 Hz with 48 Gbps bandwidth. The unit handles 12-bit, 14-bit, 16-bit, and 36-bit deep colour, RGB 8:8:8, Dynamic HDR, 3D content, and HDCP 2.3. It is built for gamers and home-theatre users who need to connect multiple consoles, streaming sticks, or PCs to one TV or monitor without swapping cables.

Plug-and-play setup with manual button switching

Installation is straightforward: connect up to three source devices to the HDMI inputs and one display to the HDMI output. The switch draws power from the connected devices so no external adapter is required. Press the button on the box to cycle through inputs; three LED indicators show the active port. The only common issue is that some low-power sources may not provide enough current for reliable switching, in which case a powered USB adapter on the source side can help.

Verify source output and cable quality before

Check that each source device can output the desired resolution and refresh rate over HDMI 2.1. Ensure your HDMI cables are certified for 48 Gbps bandwidth to support 8K at 60 Hz or 4K at 120 Hz; older cables will limit you to lower modes. Confirm the display accepts the same high-bandwidth signals on its HDMI 2.1 input. The switch does not convert or downscale signals, so every link in the chain must match the target specification.
