The decision to purchase an LCD panel as apposed to a Plasma screen can be very daunting to the uninitiated and with so much misinformation within the market place, getting a straight unbiased answer can prove extremely difficult indeed. The fact is they're competing technologies with advantages and disadvantages associated with both, what the user must remember is that they differ in how they process and display incoming video/computer signals.
One of the most informed websites to visit is www.plasmatvbuyingguide.com Here you will find various articles explaining the pro's and con's of selecting the right TV for you. You can also find buying tips and the latest news and reviews on both Plasma and LCD's. This site can provide you with all the necessary information you will require before selecting the right TV for you.
The debate about whether to buy a panel that is SD/HD or full HD comes down to practicality and cost. Depending on how far the viewer sits away from the screen can help to decide what level of technology is necessary to achieve an acceptable viewing experience. Firstly, it should be pointed out that the difference between these definitions is simply the total amount of pixels displayed in the panel, both vertically and horizontally.
For example, a SD TV consists of a resolution of 576i (576 horizontal lines interlaced) and is the equivalent of DVD picture quality. The minimum HD picture resolution is 576 lines x 720 pixels @ 50Hz progressive (576p) or it can also be 720p and for Full HD 1080i (1080 horizontal lines interlaced). What's the difference between 720p and 1080i, well progressive scanning (720p) produces a smoother, more film like look, but a 1080i actually contains more detail. Though it has fewer lines, the native progressive scan format (720p) eliminates motion artefacts that originate in interlacing, so for programmes that contain sport content 720p would be the choice. Alternatively, for subject matter that has very little motion, 1080i is capable of rendering more picture detail.
That being said, it is not essential to invest in 1080i technology if you intend to sit a distance of 3-4 metres away from your screen, the difference would be quite negligible to the eye. From 1-2 metres back it would be advisable to increase the pixel quota from 720p to perhaps 1080i, however not many of us choose to watch TV from that distance so you can afford the luxury of deciding between SD or HD or Full HD. Another thing to consider is broadcasting content, at present all broadcasters use a minimum of SD digital quality for their programming, but now free-to-air channels have included a HD broadcast that is either 720p or 1080i, for network ten this is channel 1 on the programming list.
So now armed with that information the consumer, yourself can decide on what is the best value for money panel to buy.
