We said that the 3 chip Runco's were very sharp, but, by virtue of combining the RGB colors, there's always some misconvergence with any 3 chip projector, be it DLP, LCD or LCoS. Those more expensive Runcos were very good for 3 chippers, but the LS-5 is crisper still. This is a nice, sharp single chip DLP, and that's about as good as it gets. I note that no projector is razor sharp from center to corner. That said, this projector has good optics. You'll find center to corner sharpness to be better than most projectors we look at.
For your consideration, our usual close up images
