Every THX Certified Projection Screen is tested to ensure that the optical properties do not impact the chrominance, luminance or uniformity of the projected image. THX analyzes the micro-perforations or fabric weave to make sure that it is manufactured in such a way that it’s invisible to the eye when viewed from your seating position. This acoustically transparent material makes it possible to place the loudspeakers behind a THX Certified screen, allowing for a smooth sound experience in relation to the picture.
THX Contrast Enhancing Tests
THX Contrast Enhancing Tests are designed to analyze the effects of stray room lighting and light reflections in the home theater environment. Being able to minimize light reflections is critical in home theaters with light-colored décor.
Stewart Filmscreen’s manufactures the first two projection screens to pass the advanced THX Contrast Enhancing Tests. The result? Improved black levels and better visual performance in varied light conditions.
