A TV capable of operating in those conditions has to be more expensive or else it'll need replacing twice as often and cost even more long term. Remember when Tesla used bog standard laptop screens in their dash because they were cheaper than automotive grade, leading to high failure rate?

This makes me wonder if my local McDonalds, which has three big screens mounted vertically in the drive-thru, ended up with not the commercial grade ones. They’re cooking in the sun in a hot climate all day, so they fail and turn into flickery messes, and it seems like they’re on a cycle of roughly 3 months newly-replaced & working, 1 year flickering.
