The 40DS7BJ carries a native pixel count of 1,366 x 768 which is, of course, enough to earn it its HD Ready wings.
Fittingly for what’s clearly one of the TV world’s more forward-thinking TVs, the 40DS7BJ carries a digital tuner. And as with the vast majority of digital TVs, it sports a conditional access slot for adding subscription services to the core Freeview package.
There’s 7-day electronic programme guide support too, which includes the facility to set up to 10 recording events simply by selecting the programmes you’re interested in directly from the EPG listings.
Perhaps the feature that will most define the 40DS7BJ’s success or otherwise, though, is something called DynaPix. Don’t be fooled by the vaguely prehistoric flavour to this name; this is cutting edge stuff all the way, incorporating a host of separate picture algorithms aimed at improving just about every fact of the final image.
Our choice of DynaPix’s highlights would be: a digital scaling engine that adds in extra fine detail as it goes about its business; motion-adaptive interlaced-to-progressive conversion for fighting the jaggedness otherwise seen on curved edges; contrast enhancement; MPEG noise reduction for cleaning up digital broadcasts; automatic colour optimisation; and black level boosting.
As if all this wasn’t clever enough, the whole processing kit and caboodle has now, for the first time on a JVC TV, been squeezed onto a single 32-bit processor to boost its operating speed, potentially reducing the possibility for nasty side effects to be generated.
Some of the DynaPix features mentioned above can be accessed via the TV’s onscreen menus, with one final further feature of note being a dedicated backlight adjustment.
The good news is that at times the 40DS7BJ’s pictures look nothing short of breathtaking. The bad news is that at other times they’re merely good.
