The Optoma ZK451ST-B is a 4K UHD short throw laser projector rated at 4,100 lumens. It throws a large image from close to the wall, so it suits golf simulators, home theaters and meeting rooms where the projector sits near the screen. The DuraCore laser light source is rated for up to 30,000 hours with no lamps to replace, and instant on/off skips warm-up and cool-down. Against lamp-based short throw models it wins on upkeep and startup speed; against premium home theater projectors it gives up some black level and color accuracy, and its built-in audio is basic.
