NEC NP-PA521U Projector Review – Pro and Cons

NEC NP-PA521U PROJECTOR:  Pro and Cons

Pros

  • very sharp, high resolution display with excellent focus over the entire image
  • virtually no color fringing visible on displayed text from more than couple of feet back from the screen, indicating very good alignment of LCD panels and also good optics with a very low level of  chromatic aberration
  • high readability of text and presentation graphics
  • excellent network support (wired and wireless) for control, monitoring, and multimedia presentation functions
  • built-in support for Crestron Roomview, AMX Beacon and PJ Link for connectivity and control
  • multiple NEC projectors can be controlled and managed from a central PC using the supplied software
  • interchangeable lenses along with lens shift (w/ certain lens models) should satisfy just about all mounting situations
  • extensive multimedia capabilities
  • support for multi-projector installations with edge blending, color and brightness matching and geometric corrections
  • ability to project onto non-flat, not rectangular surfaces and the ability to mount the projector at virtually any orientation makes this a versatile projector for digital signage and other specialized commercial applications
  • DICOM Simulation mode allows this model to be useful for medical education purposes
  • several out-of-the-box picture modes available with reasonably accurate colors as well as a very bright mode for use in situations where the extra light output is needed
  • excellent connectivity capabilities
  • air filter rated at 4000 hours reduces maintenance labor and costs

Cons

  • the zoom, focus and lens shift adjustments are all manual which makes setup a little more time consuming that with projectors having powered lens adjustments
  • the remote control can be difficult to operate in a dark room, since it has no backlight and there are many small buttons.  I would note the NEC on-line brochure for this projector mentions the remote being backlit, but he remote I received with the projector lacks this capability.
  • sound quality from the built-in speaker is, at best, only average for this class of business projector
  • While the 3 year length of the warranty is good, a rapid replacement service is only provided for the first year, while a few other manufacturers offer a similar replacement programs for the full duration of their factory warranties
