The quality of picture is paramount when you watch television or movies on your home theater system. The display, be it a television or produced by some kind of projection system, is the focal point of the room and centerpiece of the home theater setup. This article will explain some of the jargon used to describe picture quality in these devices and issues that you need to consider when buying a home theater display system.
There are a number of different technologies that are used to create a display system. The old type is the cathode ray tube (CRT). This technology seems to be going out of fashion now and is being superseded by plasma and LCD technology. There
...green and blue phosphors (each triad forms a single pixel or picture element) placed between two thin layers of glass, which when activated with small electrical pulses, emit color information and light to produce a display of high quality. Since ...
The resolution is, effectively, how clearly the image is resolved on the screen. That means how clear things are to the naked eye; can you read the number plate of the sinister car that drives past the protagonists apartment for example.
Resolution is often defined in terms of number of lines that are displayed from top to bottom by the screen. Standards for this are 480, 720 and 1080. That means a picture made up of 1080 vertical lines will be much clearer than a 480.
Resolution is broken down into native resolution

Another consideration of the display is the scanning method. Scanning method is simply how the video is produced on the screen. There are two methods in use, interlaced and progressive. When video is displayed on the screen it ‘draws’ each of the lines of resolution. This is done very quickly so it is hardly noticed by the eye. In the

In progressive there is no delay between the lines as they are drawn. Progressive scanning is the latest method and does not have the flicker affect and is often thought to be more film like in terms of picture quality.
Picture quality differentiation often abbreviates these two factors to give a simple way to compare competing systems. Consequently you will see a TV specification as 1080i or 1080p for picture resolution. If you were looking at two TV’s rated as 720p or 1080p then
