Sony HMD LDI-50 and LDI-100 Features

The LDI-50 has a resolution typical of home units sold for game playing and TV viewing.  For comparison, two images are presented below, one in the LDI-50 format, and the other in the higher resolution LDI-100 format.  The image below is my attempt to approximate the difference in resolution between the two HMDs by changing the resolution of a photograph.
