12 Reasons For

Expert Reviews Are Average

This multimedia projector received an expert rating of 70 out of 100 from PC Mag.

NEC Has Good Reviews for Its Projectors

NEC 10000:1 contrast ratio data projectors have good reviews on average and across all data projectors NEC is one of the superior brands.

Good High Def TV

One NEC U321H owner concluded that the product was good at displaying high definition TV. Pcmag.com scored the product 4 stars and mentioned “Its ultra-short-throw lens lets you project a large image when the projector is placed mere inches from the screen, and its 1080p full HD resol”.

Supports 3D

The NEC U321H supports 3D. Most of the other 10000:1 contrast ratio data projectors that are a comparable age to the U321H do not support 3D.

There are a number of other projectors which support 3D currently available that you might want to look at including because of it's better review score, the EH515[pl_3108717_price], or the EH515T[pl_3108718_price] both from Optoma or the Benq MW883UST[plb_3181970_price].

Supports Full HD

Unlike most of the other multimedia projectors of a similar type and age to the U321H which do not support full HD, the NEC U321H supports full HD.

There are a number of other projectors which support full HD currently available that you might also want to look at including because of it's better review score, the EH515[pl_3108717_price], or the EH515T[pl_3108718_price] both from Optoma or the Benq W3000[plb_3190084_price].
