Dragonfly™ High Contrast projection screens deliver peak performance from challenging ambient light applications by reducing glare and enhancing black levels. Contrast in an image is vitally important for rich color saturation and definition. High contrast projection screen material is the perfect solution for rooms with ambient light, or where the projector has weak black levels and high light output (many LCD/DLP projectors, for example). An image can only be as black as the screen and room allow - that's why Dragonfly™ high contrast screens are ideally suited for these challenging situations. With a gain of 0.9, the screen appears darker by absorbing extra light. This creates a richer image by maintaining color balance and enhancing black levels. Every fixed screen frame is hand-wrapped with VelTX™ black velvet, providing an elegant finish that absorbs any overscan for the perfect theater experience. The beveled 3-1/4 in. aviation grade aluminum frame is rigid, easy to assemble, and looks great too. The Dragonfly™ screen has been engineered with SnaPerfect™ technology to provide quicker screen attachment to the frame and an always-tight, wrinkle-free surface for a lifetime of image perfection. Dragonfly™ fixed screens include our Set-n-Lock™ mounting system, which features pre-measured tethers connecting the single top and bottom installation bars. This ensures a fast and easy fixed screen wall mount with the ability to slide it for centering to the projector. And unlike the competition, our Set-n-Lock™ includes clips to secure the screen to the bottom rail, keeping it snug to the wall and safe from prying fingers.
