I was in the trade show business prior to covid and I saw endless varieties of these things. Most of them were very fussy to begin. Many times they would lose picture or power for no apparent reason. Then we had to call in a sparky to try find the reason. Sometimes we lucked out, sometimes it just sat there blank for the rest of the show. This particular brand I don’t remember seeing. (I may have not noticed the brand) Because you can’t rotate the screen it’s just an info screen for businesses.
