With 4200 ANSI lumens brightness and a 2300:1 contrast ratio the 3M DX70i has enough projection power to fill a large auditorium even if the room has enough ambient light for the audience to take notes or refer to printed material.
Weighing about 8 lbs, the DX70i can travel the world thanks to its 100 – 240 V AC 50/60 Hz power supply and its compatibility with just about every TV standard in the world, including some of the more obscure variations: (NTSC, NTSC 4.43, PAL (B, D, G, H, I, M, N) and SECAM (B, D, G, K, K1, L). It's HDTV-compatible too: (480i, 480p, 525i, 576p, 720p, 750p, 1080i, 1125i).
Of course you can also plug it into a PC or Macintosh to display a PowerPoint presentation or other data. It's compatible with more than two dozen PC and Mac display modes from its native XGA (1024 x 768) resolution up to UXGA (1200 x 800) and with its two built in speakers with a two watt amplifier you won't require separate speakers in small to medium sized rooms. You can add external powered speakers for larger venues. And to bring the most to your presentations the wireless remote has a mouse function and a laser pointer.
