Yes, agree with Jeff. It was different for CRT RPTVs, which would drift out of convergence and grayscale. Not so much with grayscale now on any of the new displays, and not at all with geometry/convergence, which only applied to CRT.
I still specialize in keeping CRTs top shelf/top flight displays, with dazzling HD whether they are front or rear projected, and flat panels are a different animal completely. I do both, but rest assured that if you have a CRT based display, you can call me and I'll work my magic on it for you, from a distance if necessary. CRT owners might want to check out my long running AVS thread, "Don't Dump Your CRT RPTV!".

Lots of eye candy there. CRT tech delivers some of the finest HD out there - always has. You don't need to buy new if you have one.
