LG 4K Nanocell TV offers nice performance and good value

---

Television technology continues to advance, with many of today's screens offering picture quality and other features that could have only been dreamed about not too many years ago.

I've followed, and participated in, this evolution ever since I discovered I might be a nerd – or at least since my first colour TV. Back then, a 20-inch screen was considered the best because, as CRT-based technology, that size offered the best compromise between pixels and the (empty) space between them. You could get up to 27 inches or so (and, eventually, giant CRT's of 40 inches or so also came along) but it was argued by many video snobs that the actual picture quality was best at 20 inches.

That was analogue technology and though its resolution never really got beyond 480i, it was pretty darn good for the time, especially if you embraced the old Laserdisc technology and, then, DVD.

Now, of course, it's a whole 'nuther ballgame, with digital high-definition TV having been the rule for the past couple of decades. And now it's "ultra high definition", which is known mostly as 4K (3840 x 2160 pixels).

Today's TV's have not only grown in pixel count, of course, but in picture quality as well. Top of the line quality, as far as I've seen so far, is OLED technology, which offers fantastic colours and blacks in ultra-thin packages. The downside is that they're still expensive, appreciably more expensive than other, lesser types of panel.

LG has been leading the OLED charge for quite a while now, after Sony pretty well abandoned the technology it had actually invented decades earlier. Now, several players are vying for your OLED dollars, which should help bring prices down.
