I found the adjustment rings for zoom and focus to be sloppy, they did not move smoothly, and if you first focus the projector, then adjust the zoom, it knocks the focus off. Two points: First, this isn't that unusual in entry level projectors (Optoma's H27 also exhibits this problem), and second, this is a prototype, so it may "feel" much better with production units. That said, this issue is more of a "feel good" issue than having anything to do with performance. Afterall, once you set the projector on a table (or ceiling mount it, and adjust the focus and zoom so both are right - you are done. It's not like the zoom or focus are going to shift while you are watching content.
The control panel is located in the back right corner of the top (looking from the rear). The layout is very compact, functional and easy to navigate, just in case you have misplaced the provided remote control. The control panel itself feels very solid, and works flawlessly from a mechanical standpoint.
As you can see from the image, power is on the left side. (Press once for power on, twice for power off.) The center is the Mode select (Movie, Cinema...) and doubles as Enter, when you are in the menus. It is surrounded by the four "arrow" keys. The bottom one brings up the Menu. We will look at menu functions in the General Performance section. As you can see on the lower left, there is the aspect ratio button, which basically toggles between 16:9 and 4:3 (there's a "Real" 1:1 ratio as well for displaying exactly what the source sends - pixel for pixel. The Auto button is primarily to lock onto an analog source like a computer, and the source button - well, that says it all. In addition to the power indicator you have the obligatory Temp warning light, and the lamp indicator light which will indicate normal operation or a problem.
That takes us to the back of the projector with its input panel. The W100 projector is particularly well equipped, sporting 2 sets of component video inputs, and a DVI-I connector. The DVI-I accepts a digital signal, which is your preferred method of bringing video in from your cable/satellite box, HTPC, or Digital equipped DVD playeras well as analog (for hooking up a PC). Alternately, though, you can bring in an analog signal such as from a PC, for a business presentation. While there is no obvious way to hook up a computer (through the analog) and a digital source simultaneously, third party connectors are available that will allow you to hook both up at the same time. There is also the usual composite video and S-video inputs, and an RS232 for "command and control." Unlike most home theater projectors, however the W100 has a 2 watt speaker (we'll assume primarily for "business use"), so there is also a stereo mini-jack. There is an additional IR sensor on the back panel, and also the power input connector.
That pretty much covers the layout of the W100 home theater projector. Time to look at its performance.
