not sure how much you’re wanting to pay, but this doesn’t sound too bad. I’m looking to upgrade soon myself. I have a 40 inch dumb 1080 Element TV. It works well still, but wanting bigger and 4k. I’ll probably move the one i currently have to my son’s room.
edit: there are some better deals I think. That was just one of the first links. It’s only 60hz, you might find one that’s 120hz for not much more.
