Miracast Failure?

[GMan]

I have 3 LG TVs in the house. Two of them are 5 years old and the third is less than a year. I discovered Miracast on Windows 11 a while back - "Windows key + K" pops up available devices on the local network to share to. All three TVs are on the local network and show up in "Settings/Bluetooth & devices". One of the 5-year-olds is an LGOLED65C7P model and it does not come up in the Miracast popup.
Any ideas?

Problem solved! Turns out an LG setup operation was required, which must have come automatically with the other two models.
