In addition, there are the obligatory S-Video and Composite video inputs, as well as three stereo audio inputs. The Canon SX7 also has a stereo audio out (nice when ceiling mounting, to feed nearby ceiling speakers), a service port, and a USB port for basic "remote mousing" features (such as Page Up, Page Down).
There are two screw thread adjustable rear feet, giving the SX7 a nice, stable three point stance.
The SX7 comes with a more decent set of cables than most. There's a DVI to VGA cable for analog computer, a component video adapter, and a USB cable. Better still would have been to include a standard VGA-VGA cable so the user has enough to support two sources without having to run out and buy an extra cable.
The Canon SX7 has a single 1 watt audio speaker system - a bit basic for such an otherwise high priced, and fairly large (for a portable) projector.
The SX7, is basically a "box" projector - rectangular, deeper than wide, but sculpted with rounded front edges, and a sloping front, plus some brushed silver trim around the sides, to brighten up an otherwise neutral gray finish. Not bad looking at all, for those concerned about such things.
