Excerpt: Hitachi's CP-X205 is the most expensive LCD projector here. It has two VGA inputs and a VGA output, enabling it to display the projected image on a monitor. It doesn't have a DVI input. The lamp costs 11p an hour to run, which is almost twice the running cost of Optoma's EP727. Like the other office LCD projectors, it contrast ratio of 500:1 is fairly low.
