7 Reasons For

Vivitek Data Projectors Have Good Reviews

Vivitek projectors have an average rating of 79%, which is in the top 53% of all projector manufacturers that we have analysed.

Supports 3D

The Vivitek DX831 supports 3D, unlike most of the other projectors of this type and age which do not support 3D.

We think you might also be interested in some of the other data projectors which support 3D currently available including the Infocus IN118HDXC[plb_2945391_price], or the Optoma W316[plb_2136073_price] which has better reviews.

Other projectors which also support 3D that you might also want to consider include the Vivitek DW814[plb_3383743_price].

Has a Built-In Speaker(s)

The Vivitek DX831 has a built-in speaker(s), as do most of the other projectors that came out more than a year ago.

It may also be worth also looking at one of the alternative projectors with a built-in speaker(s) currently available including because of it's better review score, the Epson 1284[plb_3127260_price].

7 Reasons Against

Does Not Support Full HD

Most multimedia projectors of this type and age do not support full HD. The Vivitek DX831 is no exception to this as it too does not support full HD.

It is worth considering other projectors which also support full HD including the Epson 1284[plb_3127260_price] which also has a higher rating.

Does Not Support Wi-Fi

The Vivitek DX831 does not support wi-Fi, although it is worth noting that most of the other projectors of this type and age also do not support wi-Fi.

It is worth also looking at other projectors which also support wi-Fi including the EB-U04[pl_3024676_price], the EB-W31[pl_3193910_price], or the EB-W32[pl_3059517_price] all from Epson.

The highest resolution of the Vivitek DX831 is XGA (1024x768). That's 23% less resolution than a WXGA (1280x800) multimedia projector, which is the most common resolution.

An XGA (1024x768) projector native resolution is actually the worst resolution amongst all multimedia projectors of this type and age.

Across all the 15000:1 contrast ratio projectors that were released one year ago the noise levels range from 29dB to 39dB.
