Panasonic TX-P42GT20B review


Panasonic takes 3D plasma to a smaller level, and throws in its first 2D to 3D upscaling

Nearly crosstalk-free 3D pictures ; Good black level response ; Decent 2D to 3D conversion ; Good price for a 3D TV

Contrast not as good as the VT20 series ; One or two colour tone issues ; 3D images lack punch

great system!


The first TV that was delivered turned out to be faulty- the 3d glasses only sync'd with the screen when we stood up! After a bit of a faff to-ing and fro-ing to the store and phoning customer care, the TV was replaced by a fully working model!
