I’ve not looked into it much other than seeing it in this video by Jeff Geerling and making a mental note for next time I’m in the market for a TV but it may be of interest to you.
I’m sorry I can’t provide more details than that, but it’s basically a digital signage TV designed to run 24/7 for years, and as such is actually built without the absolute bargain basement parts that go into consumer units.
Money.
Also I imagine the ads will be silent but animated, like a regular website ad but full screen, essentially turning whatever you’re watching it on into a giant billboard.
It’s just another thing to block I guess.
