Interactive Short Throw Projector
July 31, 2014
Collaboration features. You can connect up to four Ricoh interactive devices over a network, interact with each, and see the same image on all four.
Ultra short throw. The WX4141Ni can throw an 80" diagonal image from less than 10" away.
Portable. The projector weighs 6.6 pounds and measures 8.7" x 10.1" x 5.7" (HWD), it comes with a soft carrying case, and it's designed to set up easily on a flat surface below a screen.
Bright image with wide brightness range. I measured the WX4141Ni in its brightest predefined mode at 3011 lumens, a solid 91% of its 3300 lumen rating. Other predefined modes came it at 1818 to 2010 lumens with the Standard lamp setting and 1074 to 1875 lumens in Eco mode, with most dropping by 41% to 47%.
With interactivity on, you're locked into a single predefined mode. With the lamp set to Standard, I measured it at 1686 lumens, which is bright enough for an 80" image to stand up to the ambient light in most classrooms or conference rooms.
As with most DLP projectors, color brightness is lower than white brightness, which is likely responsible for the color quality issues I saw with both data and video images.
Acceptable brightness uniformity. With only a 66% brightness uniformity score for the WX4141Ni I could easily see the difference in brightness on a solid color screen. Breaking up the image with text or graphics doesn't quite hide the difference, but makes it far less obvious. Unless you're unusually sensitive to this issue, it shouldn't be a problem.
