Optoma EX525ST Review


The EX525ST is uniquely tailored to be a fantastic classroom projector.

Consumer review (



Lens throw is an important factor when picking a projector. People often overlook this feature though. I've owned 3 of these for 7 months now.

Short throw lens. Can throw a very large wall size image without having to be used in an excessively deep room. 100" projection at 4 foot throw. If you want wall sized projection look for "short-throw" projectors like this one

The projector housing is a bit larger than I envisioned while researching it online. DVI and VGA input but no HDMI. Only 1024x768 native, but the internal scaler works well up to 1080p
