  I believe the Lynx's (Seiko) display is only 160x100 pixels (lo-res)...

  At the lab were I work, fiberoptic bundles are used to take the image
from a SharpVision projector to optics that enlarge the image to about
13" diagonal. Doesn't look too bad blown up to 13", so this technique
might work with LEEP optics and head coupled applications.
