NEC NP-PA521U Projector Review – Specifications 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 1.
