Epson Expands LCD Projector Line with Smaller EX Models

  • Extended lamp life, using E-TORL lamp technology to last up to 5,000 hours in economy mode;
  • PC-free presentations with USB memory devices;
  • Quick on/off (six seconds to reach the the start-up screen, four seconds to power down);
  • A/V mute slide/sleep mode, which instantly turns off the sound and images to create a quick pause in the presentation;
  • Automatic keystone correction; and
