The key is determining how much ambient light you have in a room to make sure you have bright whites and as near as blacks as possible. That's where AVIXA's PISCR (ANSI/INFOCOMM 3M-2011, Projected Image System Contrast Ratio) Standard comes into play. Learn how to test your projector setup to ensure a clear, crisp image with this introductory video.
