6 Reasons For

Optoma Has Good Reviews for Its Data Projectors

Optoma 18000:1 contrast ratio data projectors have good reviews on average and across all data projectors Optoma is one of the superior brands.

Supports 3D

The Optoma DX345 supports 3D, as do most of the other 18000:1 contrast ratio data projectors that have been available for around the same time as the DX345.

We compared this data projector to all the other projectors which support 3D and we think because of it's better review score, the Optoma W300 is also worth considering.

There are a number of alternative data projectors which also support 3D which you might also want to look at including the Optoma X350 (£283.61).
