- I think he means mis-registration. I notice this effect with my Viewsonic 6
- with certain colors (like some background colors at 1024X768 in Windows).
- Pure colors look fine, but some dithered colors show a kind of herring bone
- effect. So mis-registration will result in a fine herring-bone type pattern
- when viewing areas of certain colors, and mis-convergergence results in
- a ghosting of blue or red around white dots or lines.
