That covers the front of the X10. The left side of the projector (if you are still looking from the front), has, along the top edge, an infra-red sensor for the remote.
Also on the left are the two recessed, large dials for focus and zoom.
The X10 has no power or menu controls on the projector itself, making it completely dependent on the remote control.
On the top, centered along the back, are the power indicator and three other indicator lights.
That takes us to the back of the projector where all the inputs, and other connections are located. They are all significantly recessed, allowing the cable cover to hide the cable connections when installed. InFocus knows that most X10's will end up being ceiling mounted (which means inverted). Clever folks that they are, they labeled all the inputs upside down, so they would appear right side up when installing, and connecting cables. So, here you go - it looks upside down, but it's not.
The X10 offers one HDMI input (1.3 compatible), and a M1-DA (InFocus proprietary connector), which handles both digital (HDMI 1.3 or DVI) or analog inputs (computer, or component video). In addition there is one component video input - the usual 3 RCA jacks - S-Video, and Composite video inputs. Basically, the collection and mix of source inputs is about typical for home theater projectors these days.
