Resolution can be defined as number of pixels in a specific unit of an area. It does not include the total number of pixels that a device contains. Resolution are often described as number of pixels or a vertical or horizontal arrangement on a monitor.

This was used to determine A capability of a video card in that device and would vary between manufacturers. Over time as quality of TVs and computer monitors improved so did its resolution.

Resolution Numbers and Letters

When talking about resolution its numbers are often followed by a p or an i. For example, there are 720 p or 1080i. In resolution the letter p stands for progressive and the letter I stand for interlaced.

A screen that has interlaced lines arranges pixels in a horizontal way. These lines can be seen up close and are common on an older computer or TV models.

Pixels on modern devices are so small that they cannot be seen. An odd line comes first, and they are filled in by even lines. Interlaced devices have been increased and so has its refresh rate. This will reduce flicker that was a problem on any screen.

LED monitors call this frame rate. As this increase, flicker can be reduced so that a person does not even notice any flickering of a screen.
