Depending on what you’re looking for, you might just want a computer monitor. Those are essentially “dumb TVs” without Internet connectivity or an operating system, and they have HDMI connections, so there you go.

You can also look into commercial TVs, although more and more of those are “smart” these days. Even if they’re smart, and they tend to be a bit more pricy, they aren’t preloaded with crapware and usually have excellent warranties. So that’s another option.

What’s stopping you? Just out of curiosity.
