What is full hd?

Full HD, or full of high resolution, is the highest image quality available on consumer television. There are three different HD modes: 720p, 1080i and 1080p, but only 1080p is full of high resolution. Part 1080p number concerns the number of vertical lines shown on the screen - the higher the number of rows, the sharper the image. "P" means the screen uses progressive scan to display images. Progressive scanning shows images very quickly by completely refreshing the screen with each frame. This allows quick movements to display in sharp details.

To understand why 1080p is considered full HD, it is important to know something about other display options. Most standard TVs with resolution are 480i resolution. This means that they have 480 lines of vertical resolution and the interlaced scanned display. Connected scanning restores half of the lines at the same time, first even lines than odd lines. This means that only for each of the lines displayed is new, the second PLead is from the frame before. Another common resolution is 720p, which is an increase in resolution and improved scan style. 1080i was the next step with the improvement of the resolution, but a step back in the scan type. Finally, 1080p has both full resolution and progressive scanning.

only a device designed for running in 1080p creates a Full HD material. Many cameras, video recorders and television with low -to -medium ranges say they are able to display at 1080p, but that's not entirely true. What these items do is to create, read or display materials in lower resolution or with interlaced scanning and upscale video on 1080p. The result of the reduced is almost 1080p, but not exactly there. The image is stuttering a little, fast movement blur or certain areas of the screen will seem fuzzy as if they have not been focused. In many cases anything deposited for starting in Full HD will have a label listing 10 somewhere on your packaging80p.

There are many Full HD options, but most free air broadcasts are still in 720p or 1080i. However, many satellite and cable providers have shifted to 1080p. The number of TVs, computer monitors, camcorders and DVR, which are native 1080p, is still increasing. Many video game systems can also be displayed on Full HD and some can also play HD films.
