When I try to connect to a wireless display on my network, I always end up seeing a bunch of copies of one TV. It looks like this, with the "[TV] Samsung 6 Series (55)" being the offending party. I'd like to delete/remove these copies from the list.
I tried renaming the TV, which worked in that the TV with the new name shows up in the menu but the copies persist. This is what it looks like when anyone tries to connect to a device on our network, so it's not just my computer. The copies persist with the TV turned off, unplugged, whatever. I tried Samsung support, but they weren't able to help me.
I believe at this point it's something on the network, but I don't know how to fix it. We're running through a UniFi Cloud Key and a Sophos XG Firewall. The TV is a 55" Samsung 670D if that matters. I'm not sure what other information might be helpful, but I'm happy to provide anything else if it would be of use.
