If you buy “digital signage” or “commercial display” monitors, they won’t have built-in ad-tracking; some models have a recent version of Android built-in that makes it easy to load Jellyfin, Kodi, and other such apps; and they’ll be built to commercial specifications, meaning they’ll last longer. They can also have better screencasting features.
On the downside: they are more expensive, you’ll need to check their specs for things like bluetooth, wifi, HDMI, and other things you need; the built-in speakers are not good. The TV of course doesn’t stop any particular app from serving you ads on its own, unless you load in another app to block them.
I have a setup like this, connected to a seedbox with transcoding, and it works great.
$10 says the cops got a budget increase though
