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.
AFAIK this will only get you 720p to 1080p depending on the streaming service. No 4K, no HDR.
Buy a smart TV box like Apple TV or Nvidia Shield. You can get full quality streaming with some ads but not nearly as bad as the software that’s built into some of these TVs.
I know, I was just letting people know that this guys solution comes with downsides.
