I'm not too familiar about the technology available in this field, but I purchased the PowerLite 730c for backyard movie night. It was super -met all my needs. The projector was set up about 10 feet away from our screen and the picture quality was great - approx a 5x5 image that was very clear. I waited to start the movie until it was dark, although the projected image was clear enough to be viewed at twilight. We connected a sound system to my computer, so I cannot comment on that... I watched the ebay sales for a while, and don't think there's better than this for the price!
This are a higth precision proyector .... mid size .... very nice and clear picture... and. Powerful... I has 3 like this and works very fine.
Has some issues with overheating, but it works exactly as stated in the listing.
Verified purchase: Yes | Condition: Pre-owned
Needed a back-up projector for work. It was easy to set-up even without a manual. It is a good buy.
