7 Reasons For

Optoma Multimedia Projectors Have Good Reviews

We calculated the average ratings for all Optoma projectors and also specifically for Optoma 18000:1 contrast ratio data projectors and found that in both cases Optoma had good ratings compared to other brands.

The Optoma DX345 supports 3D image projection, as do most of the other comparable spec projectors that have been on the market for more than two years.

Alternative projectors which support 3D image projection currently available which you might want to look at include because of it's better review score, the Optoma W300[plb_2141202_price].

Has a Built-In Speaker

Like most of the other 18000:1 contrast ratio data projectors that have been on the market for more than two years, the Optoma DX345 has a built-in speaker.

We compared all the other multimedia projectors with a built-in speaker to this projector and we think the Optoma W300[plb_2141202_price] which has better reviews is also worth considering.
