The projectors also offer flexible image zoom options, ranging from 75% to 100%, allowing you to tailor the image size to your specific viewing preferences.

Another aspect worth considering is the projector's longevity and available accessories. COI projectors are designed with a durable lamp, boasting an impressive 30,000-hour lifespan. This longevity ensures years of usage without the concern of frequent bulb replacements.

Each projector comes equipped with essential accessories, including a remote control, a user manual, and a power cable.
