The home page of my $1700 smart TV has a full page ad about watching ads
(sh.itjust.works)
I just finished setting up a custom router with dns ad blocking. Next comes a media player so I can purge this smart TV filth from my household.
Huge shout out to Louis Rossmann and the FUTO communuty contributors, check out the wiki on self-hosted software if you haven't already.
Congratulations! So, how does the TV work with the adblocker set up?
It's absolutely no different! The TV is doing something weird to get around it, or these ads are just cached from earlier. I'm not sure yet. Good news is that the ad blockers definitely works, we're getting 96/100 on https://adblock-tester.com/
what brand is it? just to know what to avoid
Hisense. Name and shame baby
*with Google's TV OS
Google TV is the easiest to get rid of ads on. I have a Sony and a Hisense both no ads.
Look up and use the Projectivy Launcher.
You'll also want to sideload an app that forces the default launcher to Projectivy (can't recall the name) because they don't allow changing it through the stock OS. Projectivy tries to use accessibility settings to take over on its own, but it breaks some other features so I don't use them.
Check for HTTPS traffic as well as the regular let 53. They could be doing DNS over HTTPS to get around the block, or a static IP for a nameserver.
DNS calls are definitely cached. You'll have to wait a few days until your TV refreshes DNS entries.
