Sony’s Projection Simulator iOS tool provides easy simulation for Sony projector installers and system integrators. The tool contains an interactive simulation of throw distance for each kind of lens and available lens shift range. Different aspect ratios between screen and projection image can be calculated by selecting variables. The simulator provides theoretical values based on entered dimensions; real-world results may vary slightly due to tolerances. No login.
