As is typical, there's a front infra-red sensor for the Pro8200 projector's remote control. The control panel (more below) is on the top, towards the back right (looking from the rear). Venting is out the side, while inputs and other connectors are in the back. There's also a security bar, and a Kensington lock slot.
Underneath, there is an adjustable, drop down, center front foot, and both rear feet are screw thread adjustable.
Size of the Viewsonic Pro8200 projector has to be considered small. True, there are other single chip DLP projectors for home that are smaller, but, most LCD and LCoS projectors are a size or two larger.
Unlike home theater projectors in general, the Pro8200, as mentioned above, is a cross-over projector. It is designed to do double duty, as a home theater projector. It claims 2000 lumens, which is a healthy amount of lumens for a sub-$1000 business projector (yes some are up to 3500 lumens, etc, but 2000 - 2500 lumens has been the standard for basic portable projectors for several years now.
And the Viewsonic Pro8200 has a speaker - considered a necessity for business and education projectors.
Next comes a component video input (three color coded RCA jacks - Red, Green, and Blue). Right next store to those, are the composite video jack (yellow RCA) and a pair of audio inputs (left and right - white and red RCA jacks, plus an S-video connector.
Audio, not normally found on home projectors is a big thing for the Viewsonic Pro8200. Not only is there a rather decent sounding speaker, that can handle, say, a classroom, or provide decent sound to a movie in a pinch, but a lot of audio inputs and outputs. In addition to the two mentioned, there are two additional audio inputs (each a stereo mini-connector) and an audio out. Plus there's even a Mic input (more on that later), and a 12 volt trigger for controlling a properly equipped screen.
That leaves only a USB A, and of course, a pair of HDMI 1.3 inputs. That's a pretty complete and respectable set of inputs and outputs.
Now that we've gotton to the HDMI inputs, here's where we had big problems with the first, pre-production projector. It hated long cables, It refused to work with my PS3 or a Magnavox - with any of several hdmi cables in the 4 to 8 meter lengths. It fared only slightly better with the Magnavox, which at least was clean with a 2 meter cable. From the PS3 even that was problematic. End of conversation, between the hdmi, and the ghosts - static with the power off (the mic input), the first projector had issues.
The good news is that the newer one had virtually no trouble, where the first one was a complete disaster. There was still one longer HDMI cable that it wouldn't work with, that three other projectors had no trouble with, but overall, let's say there's no major hdmi issue, although the Pro8200 may be more finicky about cabling than some others.
