Trinitron Visual Phenomena

#2): This depends on the geometry of the frame of the grille allowing scattered electrons to go back into the edge of the visible screen; it also occured in some non-Trinitron CRTs

#3): Really? Do you mean black edges, like underscan? Not normal, and if it is underscan, should not appear on any consumer set unless something needs repair. Or are you describing a video game display that is deliberately sized small so that nothing gets outside the viewing area of a normally overscanned TV?

Great points.

3) I must have described it inaccurately, I meant overscan. Sony sets seem to have more overscan than others of the time period.

"a picture is worth a thousand words" how about posting one so we can see what your are describing.

Good point.
