I'd like to upgrade my V20 for a larger ST or GT50. However, I've read several stories about vertical banding or "the dirty screen effect" that have given me some pause.
My V20 performs fantastically well. Now that it's a few years old I don't even get floating blacks (this was a small issue when I first got the TV). The 50Hz bug can be a minor annoyance, but that's really my only complaint. That said, the TV feels small to me now (I sit roughly 2.5m from the screen). I'd love a larger screen, but I don't want a set with problems. Nor do I want to spend my time going through a potentially endless cycle of replacements.
I'm keen to hear owners' experiences with their ST50 and GT50 televisions. Has vertical banding been an issue? Should I be concerned about this? If I got a set that was affected it would certainly annoy me, though I'd really like a larger screen.
