I've looked, and it's surprisingly difficult to find one with decent resolution in a decent size. It seems they're all 1080p nonsense.
I'm not even looking for fancy features like OLED or whatever, I just want 4k in >60" screen size without any smart features. Why is that so hard??
SAMSUNG Business QE43T 43-inch 4K UHD 3840x2160 LED Commercial Signage Display, HDMI, USB, Speakers, 3-Yr Wrnty, 16/7 Operation, 300 nit (LH43QETELGCXZA), Black
What you want is a "commercial signage display". They usually have all the modern display features because they're intended to make products look good, and they're generally well built because they're meant to be on all day.
They cost more than similar TVs because they're not subsidized by smart TV shovelware and data gathering.
Huh, cool! Do you know if they tend to last longer than consumer TVs? If they include better heat dissipation and whatnot (since they're intended to always be on), it may be worth the extra price.
Not from experience, but if it's designed to be on all day and you only use it 4 hours a day (ish) it should last a long time.
Heh, same. I bought what was probably the last generation of dumb TVs. It's a 4k 65" panel from a company called Atyme which I believe is now defunct, made with an LCD panel that was part of some other company's manufacturing order but didn't pass quality check, and it has like 2010-ish TV electronics (you can tell because the settings menus look just like what you find on all the TVs from that period). It's 4k but it doesn't have any of the fancy features like HDR because the electronics are limited... but it also doesn't have a bootup delay, it just turns on.
I didn't learn about commercial signage displays until after I had bought it.
It's hard because the advertising somewhat subsidies the price.(Ie: they want the ad revenue so they will sell the display at cost with the intention that they'll make all the profit back from ads)
Yo can absolutely find commercial displays in that size and resolution, but you'll pay a much higher price for them.
It's probably worth it if they're built better, which they probably are if they're intended to run continuously. So better heat dissipation, mosfets, etc.
