The fact that JVC seems more set on making Super Slim a real mass market option right from the off rather than pursuing a high-brow premium market is also reflected in its price; the sub £1k cost we've found online really doesn't seem a lot to pay for a cutting edge design incorporating some brand new technology.
That technology is essentially a completely redesigned backlight unit and power supply substrate. Regarding the backlight unit, the JVC lab boys have managed to optimise the light-diffusing plates and light-reflection sheets that make up a key part of an LCD TV's chassis, as well as improving their overall composition. The result is that the set should deliver uniform light diffusion at all corners and edges without adding more CCFL tubes to the design - as well as ensuring that the picture remains bright enough to compete with current fatter flat boys.
For power, as well as redesigning the supply into a slimmer shape, JVC has direct mounted it on the LCD backlight unit and integrated a fanless heat dissipation system.
Clever though all this sounds, though, it does inevitably raise concerns about whether the shift to slim has compromised JVC's LCD picture quality in any way. We'll get into that presently, but first we need to point out that its Super Slim design is certainly not the 42DS9's only claim to fame.
For starters it has a very handy three HDMI inputs, all built to the key v1.3 specification and all capable of receiving Blu-ray's 1080p/24 format. Plus there's the de rigueur component video input, and everything else you'd expect any self-respecting TV to offer bar a D-Sub PC input. This lack of a dedicated PC connection is rather surprising in this day and age, but thankfully it doesn't mean you can't connect a computer at all; you can use one of the HDMIs, provided you've set your PC to a resolution of 720x576, 1280x720, or 1920x1080.
One other little limitation of the 42DS9's connections worth mentioning is the fact that although the HDMIs can handle v1.3's Lip-synch and Deep Color capabilities, they can't also take the x.v. colour system.
