Coincidentally, Google just announced a "basic TV" mode, although we don't know what TVs will ship with this feature. https://9to5google.com/2021/02/24/google-tv-basic-tv-mode/ Maybe Framework's next product should be a dumb TV, perhaps based on the latest LG OLED panels.
In addition to not having the ecosystem network effects from modules and upgrades that notebooks (our first category) have, TVs are extremely difficult logistically. You need to be able to get really great financing terms and freight rates to be able to have huge thousand dollar objects sitting on boats, trains, and trucks for weeks at a time.
