It was easy to get perfect convergence on any digital CRT TV: just adjust the position of the pixels
of the three images (not beams!) before DAC. This applies to distortion also of course.
I've seen ultra high res three-tube projectors with perfect convergence. This requires
a stable mount and screen on the wall of course.
