This means you can actually use the projector in a room that has normal lights on. It doesn't have to be dimmed. It also has VGA and DVI inputs, allowing you to connect to old and new computers, alike.
Other inputs include Ethernet and RCA. It has a 1.2X zoom lens, which isn't much but for the price, it's pretty good. Other features include automatic color adjustment and whiteboard mode. You can get the Canon LV-7275 next month for $999.
