Since December 2007 a very nice multiformat screen is what I use to view movies on.
Davision 4D Multiformat screen :
The screen has 2 separate screens which can be extended to a length that is freely chosen. This way any aspect ratio screen can be created. There are 4 memory positions to which these aspect ratio's can be stored and recalled from by using either of the 2 suplied remote controls.
