NEC PE401H Conference Projector Review
December 12, 2013,
Brightness and Uniformity -Our test model of the PE401H delivered 3,975 ANSI lumens in High-Bright, Presentation, and Blackboard modes, essentially matching its 4,000-lumen specification. The other Picture Modes performed as follows: Video and Movie - 2,880 lumens, and sRGB - 1,210 lumens. Brightness uniformity was 83% with the bottom of the image slightly brighter and with no discernible hot spots. Eco mode reduced brightness by about 28% in all modes. Unless maximum brightness is a requirement, Eco mode will provide a bright image with greatly reduced fan noise.
Image Size and Displacement - For a 150" diagonal image, the PE401H can be placed anywhere from 17'5" to 29'8" from the screen thanks to its large 1.7:1 zoom ratio. At that image size, the bottom of the image is offset about 12" above the centerline of the lens, and this displacement is good for both ceiling and tabletop mounting although it may not be ideal for shelf mounting at the rear of a room since there is no lens shift on the PE401H.
Frame delay - Frame delay was only two frames (32 msec) which is about as fast as it gets for projectors of this class. That makes for good gaming performance and establishes the PE401H as a good contender for home video projection.
Menu Position and Opacity - Unfortunately, the on-screen menu cannot be moved from its location in the center of the image, nor can its opacity be modified. This is mildly inconvenient when initially setting up the projector, but once optimum settings have been determined, it ceases to be an issue.
Menu Layering - Because the PE401H has so many setting options, the on-screen menu is necessarily layered so that menus do not become too cumbersome. This limitation causes a fair amount of button pushing during initial setup, but it is not an issue once the projector is up and running.
User 1 Settings - As described earlier, your User 1 personal settings are going to be modified if another user tries to change any Picture Mode settings.
If you have a good-sized room that needs a bright projector with high resolution, the NEC PE401H is a prime candidate. At 4,000 lumens with HDTV native resolution, this projector puts up outstanding data and video images at a modest price. Because of its size and weight, the PE401H is probably best mounted in a permanent location, but it can serve as a luggable projector when needed. It also makes a nice home video projector with more than adequate brightness even in moderate ambient light. Smooth, detailed, brightly lit images are the PE401H's hallmark, and it earns our highest rating for its performance.
