You can connect your TV and a video projector simultaneously and even use them in parallel. No switching is required; the splitter distributes the output signal to both HDMI devices. It supports video resolutions up to 4K – also known as Ultra HD or UHD. Through EDID, the connected devices communicate their capabilities, including supported video resolution and audio format. When operating two devices with different resolutions, the smallest commonly supported mode is usually selected. With the EDID switch, you can manually set the mode. HDR and Dolby Vision are supported in Copy-EDID and Mixed-EDID modes. HDMI-CEC communication is possible between the source and Display 1. ARC is not supported. It features a robust metal housing with an external power supply (USB connection).
