The projected image quality must meet THX specifications. Screen luminance, image contrast, color calibration and accuracy, and focus resolution are evaluated by THX by using standard industry test equipment, test images, and proprietary test patterns. The projected image is measured and evaluated to verify the entire image size is projected on the screen with minimum […]
