Mario is looking to get a new 3D flatscreen. Leo says good luck as 3D capable flatscreens died a quick death about two years ago. RIP 3D TV!
Mario's is concerned that since his Sony Bravia 3D TV is getting older, he soon won't watch his 3D BluRays. Leo says you can still watch them in 2D though. But if you want 3D, then make sure your existing 3D TV keeps working.
One alternative, you can use the theater experience of Occulus Quest 2 and other VR headsets to watch 3D movies.
The Chatroom says that Epson Home Cinema Projectors Support 3D. Here's a list.
