With Sony's HD-to-4K upscaling, the stairstep jaggies of HD images are visibly reduced in 4K projection. You don't get added resolution. (That can only come from the source.) But you do get a noticeably smoother picture.

4 HD images

Thanks to the four input slots, Sony 4K SXRD projectors can also accept four HD inputs to display four simultaneous high definition images. Each image appears complete in its own quadrant of the common screen. And each retains full 1920 x 1080 resolution. Here's a decisive advantage for Command & Control applications that depend on multiple feeds, for Museum Exhibits, Casino Sports Book and for any application that tracks more than one video feed at a time. The projectors also support side-by-side display of two HD feeds.
