When choosing a projector for daytime viewing, it is essential to consider the brightness or lumens of the projector. A higher lumen count means that the projector will be able to produce a brighter image in daylight conditions. While there are many projectors on the market with high lumen counts, it is essential to consider the image's quality. Some projectors may have high lumens but produce a washed-out or grainy image when viewed in direct sunlight.
