With the BenQ MH733, you don't have to draw the curtains to see clear images. This DLP projector has a light output of 4000 ANSI lumen, this way, you presentations or videos are clear in a large lit room. Don't you have space to connect a laptop? No problem. Thanks to the built-in media player, you can show photos or presentations from a USB flash drive. It doesn't matter what your project, because the Full HD resolution will show everything in detail. This could be the small letters or numbers in a presentation. The MH733 has a projection ratio of 1.15 - 1.5:1, which means that the projector has to be placed between 1.15 and 1.5m away from the screen for a projection of 1m wide. If you want a projection of 2m wide, you double the distance to 2.3 and 3m. Be sure to check where you want to put the projector and if there's room.
