12 Reasons For

Vivitek Projectors Have Good Reviews

Projectors built by Vivitek are some of the better projectors according to average reviews from users and experts.

Supports Full HD Projection

Unlike most of the other 15000:1 contrast ratio projectors that are a comparable age to the DU978-WT which do not support Full HD projection, the DU978-WT supports Full HD projection.

There are a number of alternative projectors which support Full HD projection currently available that you might also want to consider including the Infocus IN118HDXC[plb_2945391_price] which has better reviews.

It is worth also looking at other multimedia projectors which also support Full HD projection including the Epson EB-U04[plb_3024676_price].

Has a Built-In Speaker

Like most of the other 15000:1 contrast ratio projectors that have been on the market for more than a year, the DU978-WT has a built-in speaker.

We think you might also be interested in other data projectors which also have a built-in speaker including the EB-S04[pl_3066270_price], or the EB-S31[pl_3078402_price] both from Epson.

The Vivitek DU978-WT does not support 3D image projection, although it is worth noting that most of the other projectors of a comparable spec and age to the DU978-WT also do not support 3D image projection.

We compared this multimedia projector to all the other projectors with a 3D image projection and we think the Infocus IN118HDXC[plb_2945391_price], or the Epson EH-TW570[plb_2577305_price] which also has a higher rating is also worth considering.

We compared this projector to all the other projectors with a WiFi connectivity and we think the Epson EB-W32[plb_3059517_price] which also has a higher rating is also worth considering.
