This is a great TV. True to life tones unlike the over saturated LCD/LED tvs from other manufacturers. Even with SD transmissions the quality is upscaled effortlessly. An excellent array of features too, Viera cast is really handy for iPlayer and the tv also see's networked hard drives to easily play your saved movies.
I have no desire for 3D, it is awful to watch sports in 3D and also expensive to provide £100 each pair of glasses if you are to have guests round. So this being the best 2D TV around has the exact same quality as the 3D GT30 range which is also superb.
In response to previous reviews, the TV does have a slight buzz when it's cold but you have to be about a foot away from it to notice, then it goes after a few minutes.
I looked into which tv to buy for over a year, almost buying an LED samsung which are great TVs but are not true to showing tonal graduation, anything dark simply appears black. Whereas the Panasonic shows the detail and tonal variations perfectly.
I'm a very fussy customer who is very picky about what I buy. I use high end Hi-fi and expect my TV to match.
This TV does.
