My main requirement for this was that it functions well as a monitor, at native resolution, which it does flawlessly and digitally (no blurring) through a DVI connector - although there are also 2 HDMI sockets and 1 VGA in addition to the usual SCART and composite connectors. The picture is good, although from a very low angle you can notice some colour shifting; when navigating between TV programmes the response is a little sluggish but not exceptionally slow. The user interface is slightly quirky but very well presented, while the remote seems to have surprisingly few buttons which, combined with being light and feeling "plasticky", makes it seem like it's for a much cheaper TV.
The picture is as you would expect from an HD TV; this one is unusually high-res which means that it doesn't need to downscale 1080P content - seemingly its native resolution is literally the 1080P specification (1920x1080).
This kind of TV is really for a quite specific market: people who won't accept something that won't work well as a monitor and won't accept a monitor that doesn't work as a TV. You can certainly get cheaper TVs which are bigger and in some respects nicer, but they will tend to be much lower resolution, particularly compared to their size (which is important when you're sat mere inches away on your computer). You can also get cheaper monitors of similar resolution, but they will tend to be rather smaller and probably won't function as TVs. If you want HD for console games or video, you'll find more mainstream TVs are cheaper and not very discernibly worse in picture, so really this is only worthwhile if you want the TV+monitor combination.
