1080p Full HD TV Defined

There are many names for Full High Definition Television. The term has been shortened to Full HD TV and given other more catchy names such as True HDTV and Ultra HD. Another more technical term for it is 1080p. Don’t be mistaken they all mean the same thing, this type of television is basically conforms to the 1080p standard. This means it has a resolution of 1920 x 1080 pixels and employs the progressive method of scanning indicated by the letter ‘p’ after the 1080.

So what is the significance this type of TV and why TVs that conform to this standard superior to other televisions. Basically it is down to two particular aspects of HD TV – resolution and scanning method.

The first is easy to explain – resolution. The resolution is basically the number of dots or pixels that make up the images displayed on screen. It is represented in a format which is the number of horizontal pixels x vertical pixels. In the case of full HD TV this is 1920 x 1080. This resolution is shortened to just 1080 in reference to the number of lines. This is the highest number of pixels available for mainstream high definition televisions today.

Television channels broadcast their programs in resolutions up to this particular resolution. The alternative to this is televisions with 720 lines, which obviously means that there are fewer lines of pixels and therefore televisions that solely use this standard are not capable of producing as high resolutions as 1080 televisions.

Secondly the scanning method is little more difficult to explain. Now that you know the images on screen are made up of lines of pixels, imagine that as the images displayed on the television change these pixels must be redrawn. There are two similar methods that are used to do this they are called interlaced scanning and progressive scanning. Basically with interlaced scanning alternate lines of pixels are refreshed for each frame, so to refresh all lines of pixels two frames must pass. With progressive scanning every line is refreshed for every frame. The resulting effect of this is that progressive scanning produces smoother images on screen, this especially noticeable when used on large displays with fast moving action.

Knowing this it should now be a little easier to see the benefits that owning an LCD Full HD TV has over other lesser televisions sets.

Full HD TV: High Definition Television Information

Because of the changeover to digital television, high definition TV is readily available to all. The pinnacle of HD TV is what is commonly called full HD TV, this is the term used for viewing at the best quality available.

Before you can achieve this you are going to require two things, one is a full HD compatible television and the other is a full HD signal. Why is it that life is never simple especially when it comes down to technology? I say this because not all high definition televisions are ‘full HD TVs’ and not all high definition broadcasts and equipment is capable of ‘full HD formats’.

So what should you be looking for? A full HD TV is also called 1080p compatible. The number 1080 refers to the number of rows of pixels that make up the images displayed and the ‘p’ stands for ‘progressive’ scanning (as opposed to interlaced scanning). All you need to know about this is that progressive produces the better quality images when compare to interlaced scanning. So if your television is 1080p compatible is has the best resolution and scanning method available, hence the name full HD TV.

Once you have the TV, you are going to need a 1080p signal to input into your TV and this is where you could be left a little disappointed. If you are expecting to watch your favourite TV broadcasts in full HD then think again. There are very few TV channels that are broadcast in 1080p, most are actually 720p or 1080i.

However if you want to watch BluRay movies and play the latest games consoles on your full HD TV it is then that you are going to be using your TV to the maximum. So when it comes to high definition viewing might want to put a little thought into it before splashing out on the latest Full HD LED TV.
