The AcousticPro UHD (ultra-high definition) is a moiré-free self-supported acoustically transparent front projection screen material. The dense synthetic weave of this transparent screen is compatible with Ultra-High Definition/4K resolutions while mitigating light penetration for a brighter picture. The AcousticPro UHD design maximizes sound penetration with minimal attenuation without compromising picture quality. The AcousticPro UHD transparent screen material's wide diffusion uniformity offers a broad viewing angle with superb picture quality across the entire surface. This provides equal brightness levels on or off axis. "Speaking of 'observing', the Electric125H-AUHD performed admirably across a diversity of content and at all hours of day and night; its ambient light suppression was top-notch." - Brian Dipert, EDN Network Elite Screen Series: Spectrum, Evanesce, Aeon Gain: 1.0 Viewing Angle: 180° (90°L/R) Moiré-free Wide diffusion uniformity - maintains luminance levels throughout entire surface Mildew Resistant Flame Retardant: Complies with NFPA 701 Standards 4K UHD, Active 3D, and HDR ready Mean Attenuation: -2.36dB
