Of the six digital projectors under review as part of the business projector comparison review, Optoma's TX-700 is the smallest, and apparently also the second least expensive. The TX700 is a new, very compact, entry level priced DLP projector claiming 2200 lumens, and a 2500:1 contrast ratio. Weighing in at 4.4 pounds, it is small enough and light enough for those requiring a pretty bright projector for regular travel.
The TX700 digital projector includes a compact soft, padded carry case.
Each of the six projectors has it's own review, and this is the projector review for the TX700 alone. The comparison review will concentrate on the strengths and weaknesses of each projector compared to the others.
Moving to the top of the projector, you will find the zoom lens control and the control panel. The panel is pretty typical - a power button, menu button four arrow keys and and enter key. When not in menu mode, the right arrow key can be used to auto-sync on the signal if (unlikely) necessary. The left arrow key is for selecting sources. There are also the usual 3 "idiot" lights - Power, Temperature, and Lamp.
That takes us to the input panel (shown below) on the back. It is nicely laid out and has an almost surprising number of inputs and outputs for a projector in this size and price range.
To start, it has a DVI-I digital input that can handle digital, or an analog computer signal. There is also a 2nd analog input that can alternately handle component video. A stereo audio jack for the small internal speaker, and the usual S-video and composite video jacks. The TX700 projector also has a monitor out, which you would need for working with a desktop computer rather than a laptop. Having the monitor out, is usually a requirement for K-12 schools so the TX700 should be a contender in that marketplace. Lastly is an RS-232 for external control from a computer, and the rear Infra-red sensor.
That completes our tour of the unit itself. Time to look at how the Optoma TX-700 performs in terms of image, including brightness, compression technology, color handling, and more.
