The 50PS7000's pictures are also unusually dynamic for a plasma TV, thanks in no small part to an ability to produce brightness levels well beyond the capability of any other plasma brand we can think of. This aggressive if not particularly subtle talent helps the set give the impression that it has a vibrant colour palette, as well as adding drama to its black level response by virtue of the way dark image elements appear side by side with very bright, colourful ones.
Look past the surface gloss and sometimes grandstanding efforts with bright HD material, though, and neither the 50PS7000's colours nor black level response are quite as accomplished as they first appear. For instance, with standard definition, at least, even after careful calibration colours start to exhibit quite a few rogue tones, especially where people's skin is concerned.
As for the black levels, while they look good for most of the time, if you watch a predominantly dark sequence, such as the utterly stupid night-time 'liaison with a princess' sequence in the otherwise excellent Braveheart Blu-ray, there's definitely a bit more greyness around than you'd get with plasma TVs from Samsung, Panasonic and, of course, Pioneer.
Predominantly dark sequences on the 50PS7000 also highlight another concern. For frequently during my tests I noticed weird little 'echoes' of very bright image elements lingering behind for as much as a few seconds after they were supposed to have disappeared. It's possible that this problem might diminish the longer you use a 50PS7000, but not one of the other current plasma brands suffer with a similar issue, so I don't see why the 50PS7000 should either.
The 50PS7000 hits more trouble when showing standard definition sources. For as well as introducing the extra rogue colour tones noted earlier, the 50PS7000 doesn't do a particularly great job of suppressing the video noise inherent to so many Freeview broadcasts, and even a few DVDs.
Wrapping up my assessment of the 50PS7000 by checking out its audio talents, I was pleasantly surprised by just how crisp and 'alive' the TV sounds with a good movie soundtrack. It's a pity, perhaps, that there's not a bit more manly bass 'grunt' on hand to counterpoint the tinkly stuff, but the occasional harshness that thus occasionally appears isn't a bad price to pay for such a consistent level of audio clarity.
Fans of LG's plasma screens will probably just see this review as an exercise in self-justification for what I said about the 42PQ6000 recently. But all I can say is that I'm being completely honest when I state that while I appreciate its price point, the 50PS7000 is another LG plasma TV that's ultimately left me feeling slightly cold - especially when I think about what's going on in some other quarters of the plasma and even LCD worlds.
