What is HDTV?
HDTV stands for High Definition Television. HDTV is a vast improvement on traditional TV viewing quality. Most HD-ready sets are manufactured to a powerful resolution of 1366 x 768 pixels, or even up to 1920 x 1080, giving a realistic crystal clear image.

What size are the new HDTV sets?
The viewing area for HD screens is much larger than that for the typical rear-projection screen. Diagonal sizes of 40 inches or more are not uncommon and the largest luxury screen available is 65 inches. The depth of the set is also significantly different - old style TVs protrude a distance backwards, meaning they are bulky, difficult to move and position. DH LCD and Plasma screens are flat, meaning they take up very little space and can often be wall-mounted.

What is an LCD screen?
Liquid Crystal Display technology has overcome early problems to now become the dominant TV version. Large LCD screens are now available at high quality. All formats can be shown on LCD screens without a problem and HDTV is perfectly suited to this medium.

What is a Plasma screen?
Plasma display TV is a flat screen technology where visible light is created by phosphors excited by a plasma discharge between two flat panels of glass. Their larger size, better contrast, faster response time and slim, wall-mountable design has set Plasma screens ahead of LCD in the past, but LCD is now catching up - or level - with this technology.

What is an HDD (Hard disk drive)?
Hard disk drives are devices that allow recording of your TV or DVD material, at HD level. They often come combined with DVD recorders and freeview tuners, in one box. These work by storing the sound and images digitally, just as a pc would do. They are entirely compatible with satellite/ freeview channels and can enable multi-channel simultaneous viewing and recording, fully programable recording and live-TV pausing.
