Supports Full HD Projection
The Optoma S321 supports Full HD projection, unlike most of the other similar spec projectors that were launched in the last year which do not support Full HD projection.

Quite Long Service Life of Lamp in Economic Mode
With a service life of lamp in economic mode of 10,000 hours, the Optoma S321 has one of the longer service life of lamp in economic mode amongst projectors of this age.
