Benefits of LCD TVs
In the screen of an LCD TV, each pixel is produced by a tiny cell that contains a thin layer of liquid crystals. These molecules bend light in response to an electric current. It is the same display technology used in your digital watch though a little more sophisticated.
LCD televisions tend to be clearer than CRT TVs which can suffer from convergence or focus difficulties. Their improved clarity means that even small LCD TVs can display higher resolutions than the same sized CRT.
Resolution
A factor for both CRTs and LCD televisions is resolution. The number of pixels horizontally and vertically defines a screens resolution in pixels or dots per inch (ppi or dpi). The greater the resolution, the more information or image you'll be able to view at once. LCD televisions and displays are optimised at only one resolution.
Power Savings (Energy Conservation)
To keep your electricity bill down, you should look for an LCD TVs that are most energy efficient. LCD TVs operate much more efficiently than standard CRT TVs.
The ideal sound system for your digital LCD TV :
5.1 SURROUND SOUND TV
A multichannel audio system with speakers in front of and behind the listener to create a surrounding envelope of sound and to simulate directional audio sources.
A 5.1 surround sound system is one which creates the illusion of multi-directional sound through speaker placement and signal processing.
7.1 surround sound (via Dolby Digital Plus, DTS-HD, Dolby TrueHD) is the new emerging high definition (HD) sound formats. Dolby Digital Plus, Dolby TrueHD and DTS-HD all provide 7 discrete channels of sound /audio for your HD environment pleasure. 7.1 is in its relative infancy at the moment in terms of consumer momentum but none the less is available to buy right now. 5.1 surround sound is currently still the popular format due to large support via DVD titles. Over time Blu-ray will change this.

LCD TV Features
Brightness
The brightness of LCD TV is another important factor. LCD TVs have several backlights that provide illumination. Brightness is measured in units called nits. The majority of LCDs produce 150-200 nits which is fine for most users. The backlights in a LCD television are good for 10 to 50 thousand hours of operation.
Since they're fairly fragile and more likely to break, backlights usually come with only a one year warranty. This warranty is often separate from the one for the screen so you might want to extend the backlight warranty to match the duration of your LCD television warranty.
Positioning
LCD televisions can provide a range of options for positioning a display. The common way to view a screen is landscape mode (longer than wide). Some LCD TVs let you pivot the screen 90 degrees so you can view it in portrait mode (taller than wide) which is great if you're growing tired of scrolling so often (ie. using it as a computer monitor). You should also check out whether the screen can both tilt and swivel. Easy adjustment is important if you'll be doing presentations. You can even mount some LCD TVs on the wall.
WIDESCREEN TV
A format which displays pictures in the cinema format (widescreen), also known as 16:9 (for the ratio of breadth to length) - it offers the advantage of allowing feature films to be broadcast in their original version on your widescreen tv.
DIGITAL TELEVISION
The future method of broadcasting television signals. Using state-of-the-art digital technology, the new system is extremely flexible, allowing the transmission of perfect pictures in a number of display formats, including high definition and standard definition television, in both conventional and widescreen versions.
The accompanying audio is CD-quality with up to six channels (digital 5.1) of surround sound.
Digital television (DTV) uses digital modulation and compression to broadcast video, audio and data signals to television sets.

What is High Definition / LCD TV? |

HIGH DEFINITION TV and FULLHD
High definition television (HDTV) means broadcast of television signals with a higher resolution than traditional formats (NTSC, SECAM, PAL) allow. HDTV is broadcast digitally, and therefore its introduction sometimes coincides with the introduction of digital television (DTV).
1280x720p and 1920x1080i are typically accepted as high-definition scan rates. However, only 1920x1080i and up are TRUE high definition screens (FullHD).
SDTV - STANDARD DEFINITION TV
“Standard definition television” (SDTV) ; the current standard broadcasting quality for free-to-air television programming in Australia. SDTV in Australia is defined by the regulator (the ABA) as “576 lines x 720 pixels @ 50Hz interlaced (576i)”.
Current DVD (DVD9) format is also now referred to as Standard Definition (SD DVDs).
