Outdoor projectors do work in daylight—sometimes. The trick is to find one with a high enough brightness rating for the light you’re dealing with, such as the Anker Nebula Cosmos Laser 4K Projector. However, projectors often suffer at their brightest settings from color and contrast issues that might be bothersome when watching a movie. On the other hand, if you’re gathering with friends for a World Series party, and cinematography isn’t a priority, these shortcomings are much less of a concern. Generally speaking, projectors always perform best in darker environments.
