For all the 42WX70's cutting edge picture brilliance in most areas, though, it's sadly - and a little surprisingly - let down by LCD's old motion handling problem. Without the 100Hz/120Hz Clear Motion system engaged, fast moving objects clearly smear and lose resolution. And even with Clear Motion active, the picture still looks markedly more blurred with action-packed shots than the very best LCDs we've seen. In fact, I'd say the 100Hz system actually makes HD games look slightly more rather than less smeary - though luckily games are also less troubled by motion blur without the Clear Motion circuitry engaged than standard video signals.
Audio on the 42WX70 comes courtesy of an optional, detachable speaker 'bar' that can be fastened under the screen without compromising the space available for the external tuner modules. In some ways, this robustly-built bar works very nicely; there's certainly an abundance of treble information, and you can get plenty of volume out of it without distortion kicking in. But there isn't quite as much deep bass around as I'd hoped such an external speaker solution might have offered.
I should probably add that the speaker bar I was supplied with crackled occasionally, but I'm confident that this was just a problem specific to my early review sample.
Having thoroughly established itself in custom installation circles thanks to its D-ILA projectors, it makes perfect sense for JVC to follow those projectors up with the 42WX70. Especially when that TV combines some outstanding picture quality improvements and genuine innovations with - potentially, anyway - the sort of bespoke feature flexibility previously only found on megabucks offerings from the likes of B&O and Loewe. It's just a damn shame that motion smearing issue stops us being able to give the 42WX70 a truly unreserved thumbs up.
