I purchased one of these TV's for £619.99 recently. It's my first large LCD TV. My main use for the TV is standard def digital TV via a Sky box which it works well with. As expected, the picture is bright and clear but it does suffer with that slight blur to the image as most Hi-def TV's do with a standard def input.
However, connect it to a hi-def source (In my case, an Xbox 360 + HD-DVD add on) and the image comes alive. The picture is amazing and so clear. In standard def the image can sometimes be slightly jumpy during fast moving scenes, but in high def mode, everything moves so smoothly. There are a range of inputs including Scart, Component and 2 x HDMI. Plenty for me at the moment.
As with a lot of large LCD/Plasma TV's, the sound isn't like you would expect from your standard CRT TV. In my opinion it has something to do with the fact there isn't any depth to the casing so the speakers are reduced in size. I could be wrong. There is bass but it can suffer when the volume is turned up high. Not ideal for playing your tunes out loud on. But, the majority of people won't be put off by this as it will connect nicely to a surround sound system.
Overall, I have owned this TV for around 3 months now and I am pleased with it. The only thing that does annoy me slightly is the strange pattern that appears when the Channel 4 logo comes up on the screen. It seems that whenever the background is almost completely white, anything in a darker colour develops a strange alternating pattern. At first I blamed it on my Sky box, but if you pause the image then start it again, the pattern stops?! It's hard to describe, but anyone who own's the TV will no doubt know what I mean, unless it's just a problem with mine that is!
If your thinking of buying one, go for it. You won't be dissapointed. Freeview is built in and the piano black frame makes it one of the best looking LCD's available.
