Ricoh PJ WX4130N Short Throw
Conference Room Projector
Networking - This is the strong suit for the WX4130N. Not only is there an Ethernet hardwire connection, but Ricoh has added a wireless LAN board. It is simply a matter of installing some proprietary Network Utility software supplied on a CD-ROM, and connection is made to any local wireless feed. In a move that will thrill all the iPad users, Apple offers an iPad app called the Tamago Presenter which facilitates the simultaneous connection of several iPads whose common output can be wirelessly detected by the WX4130N and displayed. This is terrific for multi-user collaborations and is an indicator of the vertical integration coming to the tablet computer/projector environment.
Connectivity - The WX4130N has most of the requisite inputs for today's classrooms and conference rooms. Computers are accommodated via a VGA connector, and an HDMI input handles computers, DVD players, and similar devices. There is a composite video input, an audio input, and a Type A USB input that connects storage devices such as thumb drives although only JPEG and MPEG formatted files can be displayed. Finally, an Ethernet LAN connection interfaces with networks for projector control and Web surfing applications.
Brightness Uniformity - One of the usual limitations of short-throw projectors is less than sterling brightness uniformity. It is common to see higher illumination at the bottom of the image along with hot spots due to the vagaries of the convex aspheric mirror found in most short-throw projectors. Ricoh's internal free-form concave mirror solves almost all of the problems of trying to get a long light path into a small package, and the result is an unusually uniform level of illumination across the entire image.
Picture Controls - Like most projectors, only composite video brought the full range of picture controls to bear (saturation, tint, etc.). However, the WX4130N does allow independent adjustment of red, green, and blue regardless of the source selected, so fine color tuning is available even for HDMI material.
Presets - The WX4130N comes with only three presets: Bright, Standard, and Natural. Bright is optimized for data projections and Standard for video. The Natural setting pushed red a little too much for this reviewer's taste.
Lamp Life - The WX4130N lamp is rated for a 3,000-hour life in Normal mode and 4,000 hours in Eco mode. Since Eco mode only lowers brightness by 32% and reduces fan noise in the process, Eco mode may be a good choice for all projection conditions except high ambient light.
Warranty - At three years, the WX4130N warranty is comparable to most other projectors in its class. The lamp is warranted for 90 days.
