Sony has developed an ultra short-throw projector that is able to display a 147-inch 4K image on a plain wall and is displaying it at 2014 International CES in Las Vegas.
There is no need for any special installment or construction to use this projector. You just need to place it next to a plain wall.
Watching movies on a 147-inch screen would look great, as would an image of a beach, sunset, or world heritage site. The projected image would look like scenery through a big window.
Sony plans to start selling it in the U.S. for about $30,000 – $40,000 after summer 2014.
