Yeah this is true. The TCL TV I have has an ad for Deadpool when I turn it on. It's a dumb TV in the sense of it's not connected to the Internet but it still has these from the brief period of time where it wasn't during setup. The ROKU tvs are even worse imo it has like weird scrolling banner ads as a TV screensaver. We have a Roku TV as well.

Honestly fuck all the manufacturers I don't even want a damn 'smart' TV and I'm also pissed at everyone else that enables this by not caring. I guess I helped perpetrate it also but I had no choice I would have bought differently if I could. A lot of people don't mind having non-stop ads jammed down their throats though even by objects they own. The only time I think my TV should be showing me ads is if it's literally free.

Ours had a really sluggish menu with ads until we disconnected it from the internet. Now it has zero ads and the menu to switch sources is as fast as it should be.

I wish I had never connected it to begin with though. I didn't know better. It used to default to whatever console was on, but it updated and no longer does that for some shitty reason. So I have to go through the menu and manually switch sources now. Probably to make sure I saw all the ads before using my playstation. Assholes.
