Simplest option is probably speak to sales staff & specifically ask about the set up process. It might be worth phoning a couple of reputable TV vendors as they may have more understanding than the spotty herberts in the sheds at the local retail park.
I last bought a TV outside of your preferred time frame but back then Panasonic made, what for my needs, was the best panel for the price & didnt insist on having internet in order to set it up (no idea whether this has changed with current generation models)
It doesnt help with your hdmi concerns, but what about blocking the TV at router level or restrict it by putting it on VLAN/guest network then disconnecting it from the internet forever once set up.is complete?
For images, on Android you could use Imagepipe.
Once you’ve set it up, simply “share” the image to Imagepipe, it does its thing then automatically passes it on to whatever app you want - for example a messaging app for you to send on to others (it stores a copy of the image minus its metadata in an Imagepipe folder in your gallery for ease of access should you need it again).
For video, from memory I think mp3tag for Windows/Mac can remove metadata from some video formats
mobile Chromium doesn’t have ublock anyway…
Kiwi browser on Android is Chromium based & has had the ability to add extensions such as uBlock for years
Everyone knows the popular ones so here’s a shout out to a few that are perhaps not so commonly known:
My most used can no longer live without app:
I dunno if TV is dead per se as we all enjoy watching shows/movies. Not really interested in gimmicks - we only have 4K as all new TV’s are 4K & we only got it because our previous TV failed & they can no longer be repaired.
All i want is a good quality dumb screen. You can stick all your smart features where the sun dont shine, I’ll handle everything via a separate box that I control thank you. I’ll not be at the mercy of your shitty EULA, you won’t monitor my viewing habits or force ads into the UI or remove your dogshit apps without warning. Our TV has never been online, HTPC with a couple of USB TV tuners, uBlock Origin, an interface of my choosing, remote control & lots of storage handles everything. Still perfectly happy watching SD stuff, the only 4K we watch is YouTube.
Kiwi browser (Brave & Firefox on desktop) with: uBlock Origin, Sponsorblock, DeArrow (fights YouTube clickbait thumbs & titles, same dev team as Sponsorblock), Violentmonkey with a few scripts: Google Shut Up, Search cookie auto reject
If you’re an Android, Kiwi Browser has an option to remove AMP (use direct website over AMP version)
Another vote for Nextcloud which I self host but paid plans are available. I use Libre Office on PC. Docs synced to Nextcloud can then be viewed/edited on Android using Collabora
Has anyone said Minecraft? I haven’t played games myself for years (well before Minecraft) but live in a house where it was played for hours at a time. Soundtrack never became annoying & whenever I hear it it instantly takes me back in time.
My bank literally forces me to use their godforsaken shitty app but wherever possible I use web over app especially for corporations (eBay, Amazon, YouTube, catch up TV etc). Like you & others said, reduces exposure to data harvesting
