Reminder: Projectors with a true lumen output of 2200 lumens or higher are required for metal and gray fiberglass material screens to ensure clarity. If your projector does not meet this requirement, the screens may not be visible clearly. Please confirm your projector's compatibility before selecting a metal or gray fiberglass screen to avoid any potential issues with returns and exchanges. Any costs associated with shipping, packaging, and potential damage due to these issues are the buyer's responsibility.
