The out of box results for RGB level tracking looks a lot out and DeltaE results look high to my non-expert eye
, but the rest looks pretty good when comparing to the V20 results.
Calibrated results look extremely good, the lack of the pro filter and slightly higher black level don't put it above a V20 for me still though, def a step up from the G20, if you don't need freesat. David does say the pro filter on the GT30 makes a difference in anything but a dark room.
"Truth be told, after witnessing the GT30 with its Infinite Black Pro screen coating, stepping back down to the Panasonic TX-P42G30s less light-resistant screen meant that we werent as immediately taken by it. Unless you watch TV in total darkness (in which case the differences between the Viera G30 and the 2D performance of the GT30 will be all but invisible), wed suggest that prospective TX-P42G30B or TX-P50G30B buyers consider stepping up to the GT30, whether they are interested in 3D capabilities or not. Its Infinite Black Pro screen coating does afford the picture a certain depth and glossiness that the G30 cant fully replicate. Is this, and the fact that the GT30 is also capable of 3D display, worth an extra £300-400, though? Well leave that for you to decide."
For the money though this looks a stonking set, the ANSI contrast sounds very impressive and there looks to be some good reasons to have this over the V20 as well as the G20, unless like me your a black level junkie, in witch case I'd stick with the V20 or go GT30.
