GrayHawk LS is the large format version of GrayHawk G4. The neutral density gray shade is shared — size constraints are not. GrayHawk LS can be furnished in seamless, 40 by 90 feet, fixed frame applications as well as in large format, retractable screen configurations — the largest retractable screens in the world. GrayHawk LS extends the ability of the GrayHawk G4 fabric into larger dimensions. This neutral density gray, flexible front projection screen material enhances black levels in non-optimum viewing environments where wide seating is still needed. GrayHawk LS is just below unity gain and has excellent off-axis viewing characteristics. It is a great compromise of features, calibrated to deliver superb results.
