1600 X 1200 (UXGA) Graphics Resolution

The highest resolution supported by the NP-P451 is 1600 x 1200 (UXGA). That's over six times the resolution of the most common graphics resolution of 640 x 480 (VGA) (which is also supported by this multimedia projector). In addition, this projector support graphics resolutions of 1280 x 1024 (SXGA), 1280 x 800 (WXGA) and 1400 x 1050 (SXGA+) and 800 x 600 (SVGA).

A 1600 x 1200 (UXGA) graphics resolution is actually the best supported resolution amongst all multimedia projectors that have been around for a comparable time to the NP-P451.

A 640 x 480 (VGA) graphics resolution is the worst supported resolution amongst similar types of projector.

7 Reasons Against

Does Not Support 3D Image Projection

Most projectors of a comparable type and age to the NP-P451 do not support 3D image projection. The NP-P451 is no exception to this as it too does not support 3D image projection.

Alternative projectors which also support 3D image projection that you might want to consider include the NEC L51W[plb_1496151_price].

Read more Less Chart Edit

The NP-P451 does not support Full HD projection. Most of the other projectors of a similar spec and age to the NP-P451 also do not support Full HD projection.

We compared all the other projectors which also support Full HD projection to this multimedia projector and we think the NEC P501X[plb_1555276_price] is also worth considering.

Released Over Three Years Ago

It was over three years ago when NEC released the NP-P451.

Running Costs Are Average

Based on typical energy prices and usage levels we estimate that the NP-P451 will cost £168 over 1 year to run, which is typical compared to the other 32 4000:1 contrast ratio multimedia projectors that came out more than two years ago.

Average Projector Brightness

The NP-P451 has a pretty average projector brightness (4,000 ANSI lumens) compared to most of the other similar spec multimedia projectors that have been on the market for more than two years.

Multimedia projectors with a brighter projector brightness that might also be worth considering include the NEC P501X[plb_1555276_price] (5,000 ANSI lumens).
