Which projectors are supported?

This driver utilises the currently available settings from the Epson universal API. Current and future projectors that adhere to this API will work with this driver.

If you are using IP control please make sure that you have set the projector standby mode to ‘communications on’ otherwise you will lose control when the projector turns off.

What cool things can i do with this driver?

  • The driver has the ability to detect warnings and errors (via event maps). This makes it easily for integrators to proactively service their customers when the projector is due for a bulb change or requires immediate attention.
  • On projectors that have lens memory you can recall these lens memory positions via the driver's options. This is extremely useful if you combine it with something like the Chowmain Kaleidescape driver which can provide you with the aspect ratio feedback of the movie. Automate lens positions to suit the movie you are watching to ensure that 235 movies fit the screen perfectly without manual intervention!
  • Have the screen blank or lens closed until certain conditions, like theatre curtains being fully opened, are met
  • Event map programming to change the 3D sync setting of the projector or have the projector automatically set a 3D sync option depending on the source
  • Dynamically set the color temperature and picture modes depending on the input source
