As projected image size increases, the distribution of light over a larger area lowers the perceived brightness of any projector, thus requiring more lumens for optimal viewing. When projectors with lower brightness are used in these circumstances images can look washed out and be difficult to see and read.
ViewSonic® projectors with 4,000 or more lumens are designed for the larger rooms, screen sizes and audiences that benefit from higher brightness projection. Ideal for auditoriums, large meeting rooms, lecture halls, cafeterias and other substantial spaces – along with any space with high ambient light – projected images will be crisper, clearer and more vibrant with a 4,000+ lumens projector.
Bright enough to shine through a great deal of ambient light, projectors with 4,000 or more lumens also eliminate the need to completely dim the lights, making it easier to take notes, maintain eye contact and interact during presentations.
