Full HD TVs are capable of showing high definition images that are up to five times as sharp and detailed as old style 'standard definition' images. You'll need to have an HD source, such as a Blu-ray player, games console or HD TV to be able to really see the difference though. All TVs on sale today are HD-Ready. A Full HD TV has a letter p after it and this means that the picture is shown in the best possible quality.
1920 x 1080 is the highest resolution available on a television. Often shortened to 1080p, it refers to the number of pixels a screen can display and the level of detail it can show.
A TV that's 3D ready lets you view 3D television, movies and games in full 3D. 3D TV uses stereoscopic technology (the same thing currently being used to thrill audiences in 3D cinemas) which shows a slightly different image to each eye in order to create depth. Forget crummy old cardboard glasses, modern 3D television uses Active Shutter Technology to delivery full HD 3D movies and programmes.
To watch 3DTV you'll need a TV such as the Sharp LC40LE831, a pair of 3D glasses for each viewer and a 3D video source. A 3D Blu-ray player is a popular choice, and Sky TV have content that's available now for 3D TVs. Although in it's infancy, 3D gaming is also set to take off soon, with the Sony PS3 offering free firmware upgrades to allow people to enjoy 3D gaming in HD.
The 40LE831 has 4 x HDMI inputs. HDMI stands for High-Definition Multimedia Interface and is a standard used for audio / visual equipment. Like the older scart, HDMI is a port that allows you to connect things like Blu-ray players and games consoles to your television. Unlike scart, they're very easy to plug in - and take up a fraction of the space scart leads do. HDMI allows for HD devices to send high resolution information to the television. HDMI is an uncompressed digital signal, as opposed to previous analog interfaces such as S-Video, component video and composite video. In short, HDMI is the best way to connect your AV equipment and is going to be with us a good way into the future. There's a really good blog post over at Hi-Def hardware if you'd like to find out more.
If the idea of paying a subscription fee each month for HD television programs doesn't appeal then you'll be pleased to know that the Sharp LC40LE831 comes with Freeview HD built in. Freeview HD is the high definition big brother to Freeview and allows you to enjoy completely free access to HD stations such as BBC HD and many more. There are currently over 50 Freeview HD stations, with the line-up constantly being revised and added to. Find out what you can watch on Freeview HD here.
The 'mega' of this feature means a million. Contrast is the measure between the darkest dark and the whitest white a screen can produce. With Dynamic Contrast, the backlight is adjusted dynamically to give you better black levels. There's an excellent post on Mega Contrast over at Yahoo Answers which explains this in detail. There's some helpful tips on this subject too over at the High Def Forums in this thread.
