Due to a really long living room I need to mount my projector at precisely 4.01m away from the screen - it's where the most suitable joist is for ceiling mount. This equates to a screen size of 2.11 (given some automated figures). I'm aware that black borders really improve contrast perception so I don't want to go for a 230cm screen - or am I wrong in this assumption? Either way, the layout of the room will not allow a 190 screen due to the EPSON TW10H throw at that distance. The wall that it is projecting on to has a chimney breast so I can't use the wall! Thx for the advice!
