My convergence is very good. But, I am just using the fine mode (can use blue, green, or red) to fine tune my convergence on the crosshatch pattern in my TV's service menu. There is also a pattern that displays "stars." Know what I mean? (black background with 75 or so points of white light) You can fine tune each color on each star. Which pattern do I use, or in which order? Does it matter? Either one? Thanks. P.S. My TV is a RPTV by Sony - 3.5 yrs old.
