The resolution of TV screens
For Digital Future | September 10, 2008
Almost all HDTV screens use a fixed number of pixels to produce an image. That includes the flat-panel LCD and plasma TVs, as well as systems for front and rear projection technologies that use DLP, LCD, or LCOS.
All these pixels have a native resolution that indicates the maximum level of detail that can play a TV. Two of the most common resolutions are resolutions of 720p and 1080p.
You can also see another form of the resolutions as "1920 x 1080 pixels." This indicates with precision the number of pixels that the screen is really the first issue is the horizontal resolution and the second number is the vertical resolution. Multiplying these two numbers we see the totality of pixels is the screen. For example, 1920 x 1080 pixels = 2073600, which is usually simplified to "2 million".
These networks simulate the different sizes of pixels common in the television screen, from 480i (resolution of the old-fashioned TV) high-definition 720p and 1080p. As resolution increases, the pixels are smaller, allowing an increase in the detail of the image very important.
