10 Reasons For

Good Brand

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

Supports Full HD

The DU978-WT supports full HD, which is unusual. Most of the other 15000:1 contrast ratio projectors that have been around for around the same time as the DU978-WT do not support full HD.

It may also be worth considering one of the other data projectors which support full HD currently available including the Epson 1284[plb_3127260_price], or the Infocus IN118HDXC[plb_2945391_price] which has better reviews.

Has a Built-In Speaker(s)

The Vivitek DU978-WT has a built-in speaker(s). Most of the other 15000:1 contrast ratio projectors that were released more than a year ago also have a built-in speaker(s).

There are a number of alternative data projectors with a built-in speaker(s) currently available which you might want to consider including the Epson 1284[plb_3127260_price] which has better reviews.

WUXGA (1920x1200) Projector Native Resolution

The DU978-WT has a maximum resolution of WUXGA (1920x1200). That's over two times the resolution of a WXGA (1280x800) projector, which is the most frequently found resolution.

This multimedia projector's resolution (WUXGA (1920x1200)) is in fact the best resolution across all similar spec data projectors that were launched around the same time as the DU978-WT.

An XGA (1024x768) projector native resolution is the worst resolution amongst similar types of multimedia projector.

The projector brightness of the DU978-WT of 5,000 ANSI lumens is one of the brightest amongst multimedia projectors that have been around for around the same time as the DU978-WT.

Chart Edit
