What are the different screen resolutions?
Understanding Screen Resolution
The quality of your TV screen has two variables. The quality of your signage provided by your TV provider or your internet speed and stability.
Therefore for a 4k TV to show a 4k picture you will need both a 4K signal and TV that is capable of 4k
Pixels
They are the small dots that make up the picture you see on a screen. These pixels can only be seen if you are right up next to the screen,
when at a distance, these come together to make the picture on your TV screen.
720p
Referring to a resolution as 720p, it relates to the rows and columns of pixels on a picture. In the case of a 720p television this has 1,280
columns plus 720 rows of pixels, which is refer to as 720p. When both figures are multiplied you get 921,600 pixels. This being the lowest
resolution that can be referred to as high definition.
1080p
1080p or Full HD is where there are 1,920 columns multiplied by 1,080 rows which comes to 2,073,600 pixels twice the amount of a 720p screen.
For a number of years, 1080p is knew as the industry benchmark for high definition screens, with most content (that is, television programs,
films, and computer games) is made and dispersed in 1080p. RTE, Free to Air is now available in 1080p through a standard TV aerial.
4K
4K is commonly called Ultra HD / UHD. Theoretically, the name is a bit of a contradiction, as there are 3,840 columns and 2,160 rows of
pixels (so you would think it would be 2160p?). This totals 8,294,400 pixels, four times the amount of pixels as in a Full HD 1080p display
TV also nine times more than a 720p display. 4K content is provided by Sky’s top packages, through 4k content online and some gaming consoles.
