At 100% scale the picture quality is awesome, but my disappointment with the unit is that I don't want the unit in the middle of the living room floor to give a sensible size screen (2.7m for 100") but, if I have it on a shelf on the opposite wall, it is too far away, meaning I have to scale the image down and the quality is lost. I thought about ceiling mounting but don't want to lose the portability.
