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 Sony Bravia KDL-40EX723BU, 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.
This television features Clear Voice technology. This is a special set of audio enhancements that aim to make speech in movies, TV, commentary etc easier to hear. It works by amplifying the sound of each human voice and make it clearer against background noise.
DLNA is all about getting our digital devices in the home to talk to each other and work together. The Sony Bravia KDL-40EX723BU features DLNA making it easier than ever to connect your cameras, camcorders and other sources to your TV. DLNA allows you to connect devices easiler as well a share content over your home Wi-fi network. It's a set of rules that manufacturers work to in order to get a range of devices working together. Lean about DLNA here.
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 Sony Bravia KDL-40EX723BU 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.
Although this feature comes in slightly different flavours, depending on the manufacturer, the technology works in the same way. A light sensor detects the current lighting conditions in the room and alters the brightness and contrast accordingly. The aim is to produce the perfect conditions for the current brightness of your room. This feature can normally be turned off it needs be. The 40EX723BU has a built in light sensor.
Skype compatible TVs allow you to use the successful Skype video chat system through your TV. Skype is a fantastic way to keep in touch with loved ones when they are in different parts of the country, or anywhere in the world. You can chat with your friends and family from the comfort of your living room without a headset or computer.
To get Skype TV you'll need four things:
You can find out more about Skype for TV at the official website: http://shop.skype.com/skype-for-tv/ which has info on compatible cameras and TVs. There's also a good video on the subject below.
While just about every TV these days has at least one USB port, not all of them are capable of playing movies. Even recent televisions might be stuck with a usb port that can only be used for photos and music playback. If you like to download and watch content from your USB, make sure your TV supports USB 2.0 media playback. The Sony Bravia KDL-40EX723BU offers full support for videos played directly from your USB memory stick and you can access and browse movies using the remote.
The Sony Bravia KDL-40EX723BU has features that use content from the Internet. To use these extra capabilities, you'll need to connect your TV to the web. This can be done via your existing home Internet connection using the router supplied by your service provider.
The X-Reality Engine is the part of the Sony Bravia KDL-40EX723BU that controls and enhances the image shown on screen. A combination of computer hardware and software take each frame and 'clean it up' using a series of filters. The aim is to provide a crisper, clearer image. Two main areas of focus being colour and contrast. Three separate noise reduction filters enhance the images prior to upscaling and Sony's Image Enhancer improves texture, outline, contrast and colour.
The Sony Asia website has some more information on Bravia Engine 3, along with some examples of pictures with and without the X-reality engine - click here.
