is a LCD monitor with those specification details worth $270.40 Australian dollars / $221.46 American Dollars? I live in australia

A. Is it 20"? The spec is not bad. Rule of thumb when to purchase a new LCD monitor: Contrast ratio should be high, the higher the better (i.e: 1000:1 is way better than 500:1), the lesser the response time is always better (will have smoother graphics when you are watching or playing game), the higher the brightness is also better, and the option to have both analog and digital input is always nice to have and last, the viewing angle, more angle is better if you are looking at bigger screen size. Overall the specs is good. I think it is pretty good buy if it is 20" screen size.

what is the disadvantages of LCD monitor?
Q.

A. While LCD monitors have a lot of strengths, they still have weaknesses that might turn off potential buyers. However, it's our opinion that these disadvantages don't really detract from the benefits of using an LCD monitor.

* More expensive than CRTs. You pay for what you get; LCDs look good and are good for your eyes (see Advantages article).
* Dead pixels. When the electrical current to one or more pixels does not operate properly, one or more cells are permanently aligned, resulting in a dead pixel.
* Screen care and fragility. LCD monitors may be slim and sexy, but they're also more prone to damage and screen breakage.
* Native resolution. LCD monitors can only display information well at the resolution they were designed for. At any other resolution, image quality will suffer.
* Pixel response time. In videos and fast-paced video games, LCDs suffer from the ghosting effect.
* Viewing angles. Looking at an LCD monitor from an angle causes the image to look dimmer or even disappear completely.
* Colors. The color accuracy of an LCD monitor does not match that of a CRT monitor's.
