Test Results and Connectivity
Bright image and wide brightness range. The projector fully lived up to its 3100 lumen rating on our tests. The measured 3122 lumens is easily bright enough for the 92" diagonal image we used for testing to stand up to the typical ambient light in a conference room or classroom. For smaller screen sizes and lower lighting conditions, six other presets offer a choice of color correction settings and brightness levels that range as low as 1639 lumens. For still more flexibility, Eco mode lowers brightness by nearly 45%, to 1739 lumens for the brightest preset. It also raises the rated lamp life from 3000 to 4000 hours.
Good brightness uniformity. Brightness uniformity for the 485Wi came out to a moderately good 76% in our tests. However, the brightest and dimmest areas are far enough apart, and the change is gradual enough, so the difference is barely noticeable on a solid white screen. Break up the image with graphics and text, and it's impossible to see.
Good connectivity. The 485Wi's connection panel offers all the connectors you're likely to need, including an HDMI port for a computer or video source; two VGA ports for computers or component video, a VGA pass-through port, and both S-video and composite video ports. Audio ports include one stereo miniplug input paired with each VGA connector, a single stereo phono plug input paired with the composite and S-video connectors, a miniplug jack for a microphone, and a stereo miniplug output.
In addition, there's a USB B port for connecting to a computer for the interactive feature and for controlling the mouse from the projector's remote; a USB A port for a document camera, for reading files from a USB memory key, or for sending the image over the USB port; an RS-232 control port for a computer or third party controller; and a LAN port for data as well as for controlling the projector over a network.
