What can I buy her for the new theater room in her home?

My younger daughter had a theater room addition put on her house. It looks like a magazine cover! I’d like to get her something to put in it but I don’t know what to get. I looked at those big popcorn machines, or tried to, but they were sold out or discontinued. She is so particular I would hate to present her with something beneath par. I have no idea where she got the tv screen. It’s not a small 65” . It’s huge.
