The Sharp PG-LX2000 Projector:
Simple, Budget-Priced, and Capable

Test Results and Connectivity
Acceptably Bright with wide brightness range. I measured the projector in its brightest mode at 2557 lumens, or about 91% of its 2800 lumen rating. As a point of reference, that's easily bright enough for the 98" diagonal image I tested with to stand up to a typical level of ambient light in a conference room or classroom.
For lower levels of ambient light or smaller screen sizes, you can use any of four other color presets, which I measured at 791 to 1932 lumens. In addition, Eco mode drops the brightness by about 17%, to 2131 lumens in the brightest mode in my tests.
Good brightness uniformity. The measured brightness uniformity for the PG-LX2000 is a more than acceptable 72%. The difference across the screen is visible with a solid white image, with a slight sense of the bottom of the screen being a little brighter than the top (as confirmed by measurements). Break up the screen with text or graphics, however, and it's impossible to see any variation in brightness.
Slightly better than minimal connectivity. The connection options on the PG-LX2000 are best described as minimalist, if not actually minimal. The only choices for connecting image sources are the HDMI port for a computer or video source, a single VGA port for a computer or component video, and a composite video port. The only additional connectors are a set of phono plugs for stereo audio input and an RS-232 port for controlling the projector from a computer or third-party controller.
Notable for its absence is an audio output. If you want to use an external sound system, you need to bypass the projector, which means you won't be able to automatically switch the audio source along with the image source
