As I'd hoped, the sum total of all the effort JVC has put into the 42WX70's pictures results in comfortably the best performance standards JVC has delivered from an LCD TV to date.
Particularly significant is the depth of black level the set can portray. JVC's LCD TVs have traditionally struggled in this department, leaving dark scenes looking rather grey and flat. But the black levels attained by the 42WX70 are excellent, looking only marginally lighter than the jet black of the bezel.
What makes this all the more impressive is the fact that the new black level prowess is achieved without having to significantly reduce the image's brightness, leaving images which contain a mix of bright and dark elements looking exceptionally dynamic. Indeed, even if you deactivate the set's dynamic contrast function (which reduces brightness during dark scenes to boost black levels) the 42WX70's black levels still look excellent.
Also making a massive contribution to the image's at times jaw-dropping dynamism is the screen's much-feted colour response. There really does seem to be a greater degree of subtlety, blend finesse, and tonal expression on show via the 42WX70 than we're accustomed to seeing on normal flat TVs - so much so that at times I felt this was enough to justify the 42WX70's relatively inflated asking price.
I should clarify here, too, that while the set's colour prowess is indeed at its most eloquent when viewing digital SLR stills (even my highly amateur snaps looked somehow more professional!), it also shines through clearly when watching a Blu-ray or playing an HD game.
As usual for a JVC DynaPix TV, meanwhile, the 42WX70 also excels when it comes to fine detail reproduction. The set's ability to show even the tiniest of textures and details on a high quality Blu-ray is up there with the very best, while its ability to add sharpness and definition to standard definition sources is rivalled in my book only by Philips' Pixel Perfect HD screens.
