Thanks Gel,
I don't see a 50 series Panasonic as an option; I simply refuse to go back there.
There are no reports of uniformity problems with the GT60 or VT65 at the moment, only the ST60. As the GT60 and VT65 use a newer panel, they may be free of the vertical banding issue; though I'd be lying if I said I'm not a little worried now.
There are small problems I wouldn't fret about, like a bit of dynamic false contouring, but noticeable stripes across one side of the screen are a more than minor problem in my view.
I may be sweating over nothing. As I say, nobody has reported problems with the VT65 at this stage, at least not to my knowledge. I'm just tired of messing about and constant disappointment.
