The Epson "EasyMP" software (tested on version 2.86) is designed to remotely stream a user's computer to supporting projectors. These devices are authenticated using a unique 4-digit code, displayed on-screen - ensuring only those who can view it are streaming. In addition to the password, each projector (tested on PowerLite Pro G5650W and G6050W) has a hardcoded "backdoor" code (2270), which authenticates to all devices.
