Conclusion: The Optoma TW610Sti after a closer look has turned out to be a pretty good choice. Its manufacturer rated lumens of 3100 and its testing results of 2800 lumens have put this projector in high contention as one of the more formidable projectors on the market in the short throw interactive category. Its interactive capabilities are not as extensive as most projectors on the market, but they clearly are aligned with interactive projectors by Epson and Hitachi.
Pros: 3100 rated lumens and produces 2800 lumens in our tests., Comes with the PointBlank interactive pen., A full suite of inputs and outputs makeing it capable of just about anything., Fairly light weight at 6.9 pounds. So it’s easier to mount., PointBlank pen can be used while walking around the room., 4 adjustable feet if you plan to lay the projector on a table. Easier setup., Full featured menu system on the top of the projector in case you lose the remote.
Cons: Since it is not ultra short throw you will have a little more shadow if you use the interactive features up at the whiteboard., Remote design was a little confusing. Requires you to look at it., You have to take down the projector to replace the lamp if you ceiling mount it., Is 3D ready but does not except 3D Blu-ray content.
