There are existing brands that sell dumb TVs. Sceptre is one that I'm fond of. They compete on they aren't the cheapest usually but quite reasonable. Most people want to buy cheaper "smart" TVs though and deprive them off the Wi-Fi password, which makes it harder for dumb TV manufacturers to stay in business and get cheaper through economies of scale, which further compound the problem.
I’d really like to go with a dumb set, but their panels seem way behind.
Comparing their flagship 86” set: U860CV-UMRD (claimed) to Hisense U8 (measured, native/worst case):
3000:1 vs. 9449:1 contrast
300cd/m2 vs. 910+ brightness
60hz vs 144hz.
The hisense is significantly cheaper, so I think the comparison is fair.
Oddly, sceptre reports percent of NTSC gamut and not a modern color space. The percentage doesn’t imply poor color representation, but its a strange choice.
