TV buying guide Part I

Size and space



Blu-ray players, home cinema systems and HD broadcasting have now become commonplace within the home, and the demand for larger screen TVs has grown right along with them. TVs can now be as thin as an inch, making it easy to save you precious space in your living area or bedroom.
When selecting the screen size which is right for you, it's important to consider the space in your room and how far away you will sit from your TV. Full HD 1080p sets can be viewed in the finest details at a closer distance than HD ready sets. The optimum viewing distance for a HD Ready 40-inch TV is 2.2m compared to just 1.6m for a Full HD 1080p model. All of our sets will have wide viewing angles that will enable friends and family to enjoy the action wherever they are sitting in the room.
The visible screen size is the standard by which all televisions are measured. The measurement in inches is taken diagonally from one corner of the screen to the other. All of our screens have a widescreen viewing ratio (or aspect ratio) of 16:9. This will allow you to see the whole picture as most broadcasts are now transmitted in widescreen.

Wall mounting

Save even more space in your home by wall mounting your TV. There are a number of options available for you to choose from, helping you find the accessory to meet your viewing needs.
The fixed wall mount is the most basic type of TV wall mount. It allows the TV to be placed as close to the wall as possible, with just enough room behind it to install the cables. You'll need a good-sized wall area to allow the TV to be placed in exactly the right aspect and height for your viewing position.
Similar to the above, the tilting wall mount is fixed against the wall, however it will allows you to tilt the TV around 15 degrees vertically. This is useful when you have to install it higher than you'd ideally want, for example above a fireplace. It allows you the flexibility to adapt your TV angle when you've moved your seating arrangements or even to reduce the glare from a window.
Partial articulating wall mounts allow screens to be installed in the corner of your room. Your TV can be brought away or tucked back flat against the wall, as well as letting you position it towards the left or the right.
If you want a fully articulating mount which will enable you to move the screen to whatever position you want, view our fully articulating wall mounts. They can stay flat against the wall or extended out towards the room, turn fully left or right and titled up or down.

Our range of TVs will provide you with a truly cinematic experience right in the comfort of your own home. Slim designs mean they're perfect for sitting on stylish TV stands or to be wall mounted with our range of wall brackets.
Smaller screens are also ideal for use as a computer display, providing they have a PC input. We've highlighted some of the key differences between LED and Plasma below.

LED strengths

  • Energy efficient
  • Thinner models
  • Light weight
  • Displays darker blacks

Plasma strengths

  • Larger screen availability
  • Produces high contrast ratios and render deeper blacks
  • Colour accuracy and saturation
  • Good for motion tracking (little or no lag in fast-paced action)


The high definition revolution


The introduction of high definition (HD) television was hailed as the biggest thing to happen in TV broadcasting since the change from black and white to colour. You'll notice a huge difference with high definition TVs as they display up to 4 times the quality of current analogue and digital broadcasts. The level of detail is astonishing with clearer, sharper and more vibrant images.

How it works

The best general indicator of TV picture quality is screen resolution. The resolution is made up of lines of pixels that display the picture. The greater the resolution the higher the picture detail will be. The resolution of a standard definition broadcasts is 576i (576 lines of 720 pixels each). HDTV is broadcast in 3 different formats: 1080i , 720p and, most recently, 1080p.
  • 1080i uses an 'interlaced' system which breaks the image into 2 fields and displays 'odd' and 'even' fields alternatively.
  • 720p uses a 'progressive' system which displays each frame of the image as a whole.

Full HD 1080p

A significant number of televisions are also 1080p or Full-HD compatible. 1080p is the purest form of high definition that a television can display. This leads to a smoother, more film-like image, which will satisfy sports and movie lovers alike.
With a 1080p signal, the information that makes up an image is displayed "progressively" or all at once, rather than in an "interlaced" fashion. Blu-ray players, games consoles and Full-HD peripherals, such as your camcorder or digital camera, can provide you with 1080p images.

What you need

In order to enjoy the benefits of HDTV you'll first need a Plasma, or LED TV that is labelled 'HD ready' or being 'HD 1080p'. A TV may be labelled 'HD ready' if it meets the following criteria:
  • It must have a minimum resolution of 720 lines in wide aspect ratio.
  • It must support both 720p and 1080i formats
  • It must have a HDMI (High Definition Multimedia Interface) or DVI (Digital Video Interface) input that supports HDCP (copy protection)
  • It must be compatible with analogue HD sources (e.g. camcorders)

Upscaling

Some televisions will take a standard definition signal from a DVD player or the built-in digital tuner, and give it a HD "makeover". While this does make the picture better, the benefit of HD is appreciated fully when used in conjunction with a compatible source such as a Blu-ray player.
