Jesus, again already?
Or just buying a regular TV and not connecting it to the internet. Signage TVs are specialized and will cost a lot more for a lot less.
Because nobody buys them? I have a reasonably nice 1080p60 dumb TV, and when I decide I want to upgrade, I’ll be looking at 4k (or maybe 8k) signage displays. Being part of an app ecosystem at this point is a design defect on a TV, and the superior product costs more, so fewer people buy it.
I also suspect the usable life of a smart TV is a lot lower, to the point that paying twice as much for a signage TV may not equate to twice the price in the long run. Fewer parts outside the panel that can slow down or fail entirely
Because they’re a specialty product sold to businesses not mass produced products sold to budget-minded consumers.
I also doubt they’re technologically superior as they’re just designed to display a static McDonalds menu for 18 hours a day, not play Dune in HDR at a massive bitrate. I’m no fan of tracking or similar corporate bullshit surrounding advertising but you’re making a lot of (almost entirely) assumptions here about these signage displays. You’ll likely be paying more than 2x the price of a comparable model considering these are likely equivalent to Black Friday TVs.
