Test Results and Connectivity
Brightness issues. The measured brightness for the MW519 was about 93% of the rated 2800 lumens, at 2599 lumens in its brightest mode and a range of 1113 to 2022 lumens in its other modes. In Economic mode, the brightness dropped by about 17%, to 2146 lumens in the brightest mode.
As with the MS517, and more than with most DLP projectors, these numbers really count only for screens with white backgrounds, like a word processing document. The projector's color brightness is enough lower than its white brightness that color screens are noticeably dimmer, even with images like a Windows desktop for example.
Color brightness measurements for various modes came out to a range of only 328 to 628 lumens. One way to look at these numbers is that 2599 lumens for white brightness would make a word processing document with a white background suitable for a 194" to 263" diagonal screen, based on SMPTE recommendations for theater dark lighting, while 628 lumens for a color image would be bright enough for a roughly 95" to 129" screen size.
Acceptable brightness uniformity. The MW519 delivers near uniform brightness across the entire screen, despite a little lower score on measured uniformity than most projectors, at 66%. That's enough to show on a solid white screen, but with the image broken up by text or graphics, it's hard to see a difference even if you're looking for it.
Acceptable connectivity. The MW519 offers the identical set of connectors on the back panel as the MS517. The one important oversight is the lack a USB A port for reading files from a USB memory key.
