Here’s how to turn off “automated content recognition,” the Shazam-like software on smart TVs that tracks what you’re watching
These TVs can capture and identify 7,200 images per hour, or approximately two every second. The data is then used for content recommendations and ad targeting, which is a huge business; advertisers spent an estimated $18.6 billion on smart TV ads in 2022, according to market research firm eMarketer.
Purchase the nicest screen you can and then hook it up to a HTPC.
You can get a Beelink mini PC for $150-$700. I have a quad core Celeron gen 11 that can handle up to QHD/2K H264/5 video fine, but stutters on 4k. I bought it ($159) knowing that because power draw is my main concern (offgrid/batteries).
When I have an Internet connection I use Jdownloader for YouTube, and Sonaar / Couch Potato / Headphones / SabNZB for everything else.
Rounding that out is a Cable capable USB HDTV card that I use for local OTA TV.
I'm running LibreELEC with some customizations I've done for my personal workflow.
Can't recommend it enough. Fuck the marketing predators that lurk in what you 'own'.
The trouble is you can't find decent sized monitor panels at reasonable prices. Frankly your most practical bet is to buy a TV with minimal smart functions and never connect it, then use that for your media PC. Also maybe hack the TV, that should be far more common IMO.
