Some people say that there's no difference between a regular a television picture, and a LED (backlight screen) with HDMI cable. They're wrong though. This TV has one of the best resolutions I've seen, and if you doubted LG to make top-quality tech beforehand, this product would change your mind quickly.
The picture is fully HD, 1080p, and has something called 'Mega Contrast Ratio', the purpose of which I'm not certain of, but whatever it does it works. The picture is incredibly clear and extremely defined, with images sharp enough to perform minor surgical procedures with. There is also a selection of picture modes to select from which, surprisingly, actually make a difference, including 'Intelligent sensor' which actually adjusts the picture according to the light in the room (I think), and the format of the video you're watching. Unlike some other brands of television, the picture modes do effect your enjoyment, and you can adjust it to fit different camera modes such as Cinema, Sport, Game and so on.
Sound is another area in which this TV scores highly on. When I first switched to this model I was surprised how good the sound quality was, which has stereo surround sound in-built, which is almost of home cinema system quality. Noises are clear and crisp and slight sounds can be heard easily, which makes the monitor great for gaming. The only down side is the hum the TV emits, which some newer HD tellys have managed to get rid of.
The button layout for this TV is average however, with some slightly irritating features such as the arrow which would usually turn the volume up (the one pointing left) turns it down, but this doesn't take long to get used to. On the other hand, on my T.V a message quite frequently states: 'Is This TV connected to your Computer' in a large box, obscuring a game of Battlefield 3 (see my other review.) However, a lot of flat-screens seem to have their controls squashed round the back, to the side of the TV screen so it's much more convenient to have all of this model's buttons at the front, clearly labelled, on a touch screen capacity.
So, in summary, the picture and sound is the best I've seen and heard on a television this size before, and can be found as cheaply £250 meaning this should defiantly be bought if you want something in between HD Ready and 3D. Just bear in mind this is a monitor TV, and won't show BBC2 or anything.
