What you mean by black hole and filter? I blocked a bunch of tcl domains on my pihole and made my router drop everything in port 53 coming from every other device that wasn't pihole. It seems to have worked for now.. Is that a good solution?
Pi-hole blocks the name resolution. TV wants to go to Hisense.com, asks your Pi-hole where that site is. Your Pi-hole sees that Hisense is on a block list, so it says back to your TV "sorry, no idea how to get to that site, it must be offline."
If the manufacturer wants to get around this, they program a public DNS in, like 8.8.8.8, or they hardcode the static IP for their website into the TV. Now when it wants to go to Hisense, it never has to ask your Pi-Hole where that site is, and it doesn't get blocked. Heck, it probably won't even show up on your Pi-hole's logs.
If you black hole the site, then any traffic going out there gets dropped, and the hard-coded addresses on the TV don't matter for shit.
Where can I find out more about black holing a site?
I don't think my tcl TV has it hardcoded because my pihole is always blocking tcl domains
