Here is a screenshot from the KVX 370 Indextron with 3.7 inch CRT. The camera was just a few inches away. If viewed from several feet, the index stripes are not as visible.
This is a screenshot from the bigger brother, Sony IDX 5000 Indextron. It has a 5.25 inch screen with finer pitch. After this shot, the scratches on the plexiglass screen cover were buffed out. Again, looks better from a few feet away. This shot is larger then actual size.
