Test Results and Connectivity
Bright image with wide brightness range. As with most Epson projectors, the EX3212 came in at roughly its claimed brightness on our tests, at a measured 2882 lumens, or 103% of the 2800 lumen rating. That's easily bright enough for the 98" diagonal image I used in testing to stand up to the ambient light in a typical classroom or conference room. As a point of reference, using SMPTE recommendations, it's suitable for roughly a 230" image in theater dark lighting.
For smaller screen sizes or lower ambient light levels, you can lower the brightness by using one of six other presets, which I measured at 1581 to 2396 lumens. You can also switch to Eco mode, which drops brightness by about 22%, to 2250 lumens in the brightest mode. Keep in mind too that because the EX3212 is an LCD projector, it offers the same brightness for color lumens as for white, which means that a color image -- whether a graphic, a photo, or a scene in a movie -- will be just as bright as a text document with a white background.
Excellent brightness uniformity. The EX3212 also does a good job of maintaining uniform brightness across the screen, with a measured brightness uniformity of 85%. Just as important, the brightest and dimmest areas are far enough apart, with the shading between them changing gradually enough, so I couldn't see any difference in brightness on a solid white screen.
Acceptable connectivity. Not surprisingly, considering the price and small size, the EX3212 offers relatively few connectors on the back panel. However the list includes most, if not all, of what you're likely to need.
- 1 HDMI
- 1 VGA IN (for RGB or component)
- 1 S-video
- 1 RCA composite
- 1 USB A (for directly reading files from USB key)
- 1 USB B (settable for controlling the projector from the computer or for mouse control from the remote plus direct USB display and audio.)
- 1 RCA stereo IN
