I don't even understand the pitch? you have the disc playing, in your hands, your ownership, no buffering, no subscription required. and they're saying....hey do you want a worse experience?
i heard you can buy the monitors hanging over the counters at mcdonalds from the OEM where the "smart" is a module you have to buy seperately. is it something like that, or was it sold as a really big PC monitor?
They're called digital signage displays. Those module slots are usually in the intel SDM form factor.
This stuff is expensive as these displays and modules are rated for 24/7 operation and the software they ship with by default is specifically made to manage content on a large fleet of them.
You're honestly gonna get a way better experience for cheaper by getting a normal TV + a NUC/Nvidia shield and just not connecting the TV to a network ever.
since the processing power doesn't matter and it's not being connected to the internet, it can be any chinese underspecced tv as long as the screen itself is good.
