I'm trying to make screen mirroring work with my own DNS by creating the static PTR SRV and TXT records. I create all the necesary b._dns-sd._udp lb._dns-sd._udp _services._dns-sd._udp and coresponding _airplay._tcp _raop._tcp records. That seems to work as I can see the records in dns-sd -Z _airplay._tcp and dns-sd -Z _roap._tcp or in the Discovery Browser app But for some sort of reason I cannot seem to see my displays in the Screen Mirroring menu If anyone has any suggestions, I am all ears.
