Plug-and-forget auto sensing only works correctly for devices that do not output continuous voltage over the HDMI port when turned off. Powering on a device gives it output priority over the other two devices. Output priority is given to the next device on the switch if the current output device is turned off. Make sure the connected devices supply enough power to the switch.Devices that require HDCP 2.2 or higher may be incompatible (e.g. Roku 4).Please use High-Speed HDMI cables that are ≤50ft/15m. 28AWG recommended.
