The Optoma EW536 is a DLP projector that comes in a square and boxy black plastic housing. The combination of matt and gloss black gives it a stylish look, while the built-in lens and zoom ring mean it's safe to carry around. Unlike the Epson EB-W10, which has focus and zoom rings side-by-side, the Optoma has a zoom ring on the top of the unit, while the focus is hidden away on the front of the device. This may initially prove unusual for first-time users, but we didn't have any problems getting a sharp and focused image.
