ViewSonic PLED-W200 Portable Business Projector
There are actually vents on the front, rear, one side, and bottom of the PLED-W200; in fact, the only sections that don’t have one are the top and the side that contains the CEA adapter port, mini B USB port, and SDHC card slot. The rear also has the power adapter connector.
On the bottom of the device are two rubber feet with a third foot (located under and just to the side of the lens) that adjusts to alter the viewing angle. There are plenty of controls on the top of the projector, including the manual focus control that is conveniently large enough for anyone to find and adjust in the dark, as well as power and temp indicator lights; up and down directional keys for the menu; and Power, Menu, and Enter buttons.
While the on-device controls are well-placed, it’s a bit awkward to use them; because the PLED-W200 is so light, the force of pressing a button will usually move the device slightly and force the user to readjust its positioning.
The menu is straightforward enough, with seven tabs: Source, Picture, Video/Audio, Setting, Option, Information, and Language. The Picture tab lets users toggle through several different color preset color modes, including two user-defined presets, adjust keystone settings, and select an aspect ratio. You can adjust things like frequency, tracking, and speaker volume under Video/Audio, and under Settings you can toggle between projection types (such as front table or ceiling-mounted), power settings, and other minor details. The Options tab lets you change the background color when the screen is blank, set a password, use digital zoom, and more.
