HD Ready

The LE40R74BDX is High Definition Ready. HD ready concerns the ability of television receivers to display high-definition pictures. The term has had official use in Europe since January 2005 when, EICTA (European Information, Communications and Consumer Electronics Technology Industry Associations) announced the requirements for the label.

EICTA introduced the label as a quality sign for the differentiation of display equipment, capable of processing and displaying high-definition signals. It is awarded on the basis of minimum functionality requirements that are detailed in the "EICTA conditions for HD Labelling of Display Devices".

In the USA, "HD Ready" refers to any display that is capable of accepting and displaying a high-definition signal at either 720p, 1080i or 1080p using a component video or digital input, and does not have a built-in HD-capable tuner.

Signal Reception HDTV

The rise in popularity of large screens and projectors has made the limitations of conventional Standard Definition TV (SDTV) increasingly evident. An HDTV compatible television set will not improve the quality of SDTV channels. To get a better picture HDTV televisions require a High Definition (HD) signal. Typical sources of HD signals are as follows:

Over the air with an antenna. Most cities in the US with major network affiliates broadcast over the air in HD. To receive this signal an HD tuner is required. Most newer HDTV televisions have a HD tuner built in. For HDTV televisions without a built in HD tuner, a separate set-top HD tuner box can be purchased.

Cable television companies often offer HDTV broadcasts as part of their digital broadcast service. This is usually done with a set-top box or CableCARD issued by the cable company. Alternatively one can usually get the network HDTV channels for free with basic cable by using a QAM tuner built into their HDTV or set-top box. Some cable carriers also offer HDTV on-demand playback of movies and commonly viewed shows.

Satellite-based TV companies, such as Optimum, DirecTV, Sky Digital (In the UK and Ireland) and Dish Network, offer HDTV to customers as an upgrade. New satellite receiver boxes and a new satellite dish are often required to receive HD content. Video game systems, such as the Xbox (NTSC only), Xbox 360 and Playstation 3, can output an HD signal. Two optical disc standards, Blu-ray and HD DVD, can provide an HD signal.

HD Ready Caveats

The fact that a product bears the label "HD ready" does not necessarily mean that it can display the full picture resolution possible from a HD source. Most HD-ready sets do not have enough pixels to give true pixel-for-pixel representation without interpolation of the higher HD resolution (1920x1080) - or even the lower HD resolution (1280x720) horizontally (CRT based sets, or the plasma-based sets with 1024x768 resolution).

The term HD compatible is also being used in Europe to indicate that a display device has HDMI capability but with lower than HD-ready resolution.

To view HD you need a high definition display and there is an industry 'kite mark' to show whether a particular display is ready for high definition broadcasts. This web site will show you which displays have passed the tests and are 'HD ready'.

To check a display, use the form on this page: select a brand, or enter all or part of a model name and number, or choose a screen size and click the 'Show me' button.
