The quiet Eco mode allows a comfortable operation in the bedroom. The contrast values of the 3-LCD technology are certainly not as good as DLP, but you have no rainbow effects (and it saves the additional noise by the DLP color wheel). Should lose no resolution to the projector mount that one does not have to use the keystone correction (which I see as a wonderful stopgap for temporary use - for fixed installations, it would be a shame permanently on "selling" pixels to dispense).
In summary, one can say that the price of a 50-inch TV superclass gets a large-screen home theater experience including 100 inch screen (same full HD pixel count to 4 times the scene inflated!).. You trade image quality and contrast against a monstrous "Wow" experience -> makes a lot of fun, but you can not stop to look closely :-)
