With 4000 ISO Lumens and a contrast ratio of 2000:1 the WXGA-resolution Epson PowerLite 1925W Multimedia Projector has the projection power to present large images in venues where ambient light would be a problem for lesser projectors. However, it's a gentle giant that works and plays well with others. It's got an international 100 – 240 V AC 50/60 Hz power supply and it can handle NTSC, PAL and SECAM TV signals. It can also project 720p, 1080i and 1080p high definition signals. And those signals will stay in pristine digital form from the source thanks to the 1925W's HDMI port.
