The VSW12100 is an HDMI switch that allows you to use two HDMI sources, such as a PS5 and Xbox Series X, on a single HDMI display. The switch supports 4K 120Hz, VRR, and HDR, including Dolby Vision. You can switch between the sources either manually via a button or automatically to the last activated source. The switch requires a USB power source, although in some cases this may not be necessary. HDCP 2.3 is supported, as well as all common audio formats. Automatic switching does not work with all devices, such as Apple TV or Shield TV.
