Samsung Premiere can project a 100-inch screen with only 4.5 inches. It has a built-in 40W, 4.2-channel audio system. Although it is not a stand-in for a dedicated external audio system, watching TV is sufficient. This projector uses red, blue, and green laser technology to show brilliant 4K images. It has a 0.66 inch DMD (DLP chip) with a specified brightness of 2800 ANSI lumens. So is SAMSUNG Premiere worth buying?
