I should say right away that I couldn’t get hold of the CX100 tuner box JVC does for the 42WX70, and so have reviewed the screen using my own source gear (Sky HD box, Blu-ray player, Xbox 360/PS3, PC) connected via the three HDMIs and PC VGA port built into the screen. But then actually I suspect this will reflect the set-up situation/preference of many of our readers too, at least until some of JVC’s more exciting external tuner box options come through.
One last unique selling point of the 42WX70 is its colour range. For in a move designed to make the TV irresistible to serious photographers, the 42WX70 enjoys a remarkably wide colour gamut able to show 100 per cent of the sRGB/HDTV colour spaces, and 96 per cent of the Adobe RGB colour space.
This latter fact means the TV should be able to show HD digital SLR photographs with unprecedented accuracy – as well as, we’d hope, delivering extra subtlety and dynamism with our favourite video sources. With this in mind, it’s reassuring to see that JVC provides a decent list of colour space options, as well as a seemingly reliable Auto mode if you’d rather not think about this key issue for yourself. It’s worth adding here, too, that every 42WX70 panel is calibrated to the 2.2 gamma setting before leaving the factory, ensuring – hopefully! – exactly the same colour accuracy on each and every panel that’s sold.
Further exploration of the onscreen menus reveals that the 42WX70 is remarkably flexible in all kinds of different ways – a reflection, no doubt, of both its sophistication and its desire to appeal to the custom installation market that’s likely to be so key to its success.
Among the most helpful of the reams of tweaks on offer are: a sophisticated colour management system; white balance fine tuning; gamma adjustment; two types of noise reduction; and the de rigueur Eco option, which adjusts the image settings to get the optimal power efficiency out of the screen.
There are some promising things going on with the TV’s processing, as well. For starters, the TV features the very latest version of JVC’s usually very credible DynaPix HD system, which works on a whole host of picture elements and is especially renowned for increasing the sharpness of standard definition sources.
Then there’s 100/120Hz Clear Motion Drive II processing, designed to reduce blur and judder when watching PAL and 24p sources. And finally there’s a Real Bit Driver – which you can deactivate if you wish – that applies 12-bit signal processing to each of the red, green and blue colour elements.
