Yep, a commercial display is what OP is looking for. You won't get fancy stuff like high framerates or digital audio processing, and they cost a bit more as many of them are meant to be on 24/7/365, but there are no apps installed. They'll have network connectivity, but only so you can manage them.
Be careful when buying commercial displays for digital signage, some do not have speakers built in, though they should still have a 3.5mm and/or optical out and you can always strip the audio from an hdmi cable.
Quite right. I did get one with speakers, but they were even worse than I expected. I bought a sound bar to go with it. There are also a few quirks that remind me it's a commercial display. Like there's no power button on the unit. I have to use the remote. I suppose one wouldn't want their signage turned off by randos.
They have robust command documentation as well, so controlling them over a network is pretty easy. Lots of possibilities there.
