Sony 4K Ultra Short Throw Projector. With the size of televisions still getting larger, the size of your living room walls to house all of the technology is not necessarily growing at the same rate. Sony has come up with a solution to this problem. The Sony 4K Ultra Short Throw Projector is placed mere inches away from the wall, but produces a 147-inch, 4K image. By placing it next to the wall, there is no problem with viewers interfering with the projection, so no viewer shadows. The projector is available for purchase at major retailers starting at $1,299.
