Conclusion: For a short throw projector, the Acer S5201M is a solid performer both in brightness and sharpness. While this alone can be matched by other projectors on the market, the S5201M separates itself from the pack by including interactive ability at a very low price. While I had some issues with the interactive software, I believe that with a little getting used to, it would be more than adequate for most uses.
Pros: Good brightness, Sharp image with any resolution, Interactive pen works well, If mounted, lamp can be changed without unmounting the projector, No dust filter to clean or replace, Can be projected on a variety of different colored surfaces, Can present from USB drive, 3D ready
Cons: Primary colors are dark in the Bright mode, DLP rainbow artifacts are noticeable with video, Whiteboard software could use improvement
Summary: For a price tag of Rs.75,000 (plus taxes), the Acer S5201M feels quite expensive. On the plus side, it does have plenty of connectivity options and some nifty networking features that would appeal to a system admin, but this does not make up for the fact that the overall picture quality is just about average. The short throw range is great if you don’t have a lot of space to play around with, but text appears pixilated most of the time due to the low resolution.
