Posted on February 18, 2015 by Art Feierman
NEC NP-PA521 PROJECTOR:  Summary   The NEC NP-PA521U is a very capable business/installation projector that covers all of the bases with a bright image, good out-of-the-box picture quality (and very good with calibration),  great networking support with computer-based control and presentation capabilities, highly flexible mounting options, great support for multi-projector installations, interchangeable lenses for maximum flexibility, and many other features.  The sections below summarize some of the capabilities of this projector.

Picture Quality

The NP-PA521U offers a native 1920 x 1200 resolution and it shows when projecting text or presentations where the text is very clear the finest details visible.  For still viewing photos or video this NEC model does a very good job with good out-of-the-box color accuracy that can be further improved with a professional calibration or even making just a few user adjustments.

Video and Audio Performance

The NP-PA521U puts out a very bright image easily meeting its published 5200 lumen specification in the brightest mode.  If offers excellent image sharpness thru the combination of a high native resolution and a quality lens.  Brightness and color uniformity were both good and the best out-of-the-box picture modes offered good color accuracy, which can be further improved with calibration.  Contrast and black level performance was typical for 3LCD business projector, which is to say not as good as with DLP and LCoS based models, but still perfectly acceptable for the vast majority of business/commercial applications.

The NP-PA521U's built-in 10-watt speaker is adequate for use in a small to moderate size conference room.  However, using higher quality external speakers would be appropriate for larger venues and/or where higher fidelity audio is desired, especially for music reproduction.
