Screen Materials Quick Reference Guide


FireHawk in its fourth generation is a flexible front projection screen surface engineered for use with today’s high-powered projection technology in applications involving the presence of ambient light. 

Ambient light is the enemy of two-piece projection. Screens designed to reject ambient light can be effective at furnishing an image in even the brightest of rooms,but the trade-off is the presence of unwanted artifacts such as color-shift, hot-spotting, and poor off-axis viewing. Stewart Filmscreen is in the business of image fidelity, and FireHawk G4 was designed to provide the best possible tradeoff between image fidelity and ambient light resistance. With improvements to uniformity and off-axis viewing, FireHawk G4 is even closer to the reference quality and image fidelity that have long been synonymous with Stewart Filmscreen.
