You wrote two messages in tandem so I reply here:
- no problem to find a projector screen that can fold up that gives a good contast with a projector cheaper than a beovision 77" but as I said, I do not have space for a 77" tv and for cinematic experience I would really like a really big screen! A small OLED can never compete with that imho. If so, then all cinemas would also be OLED ;)
- PS5 can be plugged into the soundcenter, of course, in the current gen there is no good support - which is also why it needs to be updated.
