Detection failure refers to the inability of a system or device to accurately identify or detect another component or device. In the context of HDMI, IPCManager, or Device Manager, a detection failure would mean that the Device Manager is unable to properly discover the encoder in the local area network or encoder is failed to detect input signal of HDMI.

If it shows 1920*1080P@30HZ on GUI, probably it's failed to detect the HDMI signal. Take the following steps if there is a failure to detect an HDMI signal. Ensuring that the HDMI cable is properly connected and meets the necessary requirements, as well as checking and adjusting the output resolution of the HDMI signal, can often resolve detection issues.
