A Guide to Technology

There is dissimilarity between full HD and HD ready. There are many companies launched there TVs and monitor’s but the customer confused that which one is better. At that moment your knowledge is aware you to buy perfect thing.

Let us discuss about the difference between full HD and HD ready.

Firstly, know that what is HD? The full form of HD is High Definition; this all is about the signals and clarity of vision that you seen with the help of vision media like television, Projector and others. HD is the system of higher resolution than standard-definition (SD) video, and most commonly involves display resolutions of 1280×720 pixels (720p) or 1920×1080 pixels (1080i/1080p).

Resolution of Standard Definition (Conventional) TVs is 720 H x 480 V = less than 1 million pixels.

Resolution of HD Ready TVs is 1366 H x 768 V = 1 million pixels

Resolution of Full HD TVs is 1920 H x 1080 V = 2 million pixels.

* H = number of Horizontal pixels, V = number of vertical pixels

FULL HD

1080p is the shorthand name for a category of HDTV video modes. The number 1080 represents 1,080 lines of vertical resolution (1,080 horizontal scan lines) while the letter p stands for progressive scan 1080p can be referred to full high definition although 1080i is also “Full HD” (1920×1080 pixels). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total. The frame rate in hertz can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 Hz.

The meaning of 1080p as a display resolution is not correct because in fact 1920×1200/1920×1080 displays may or may not be able to display 1080p video. Use of 1080p and the closely related 1080i labels in consumer products may refer to a range of capabilities. For example, video equipment that upscales to 1080p takes lower resolution material and reformats it for a higher resolution display. The image that results is different from the display of original 1080p source material on a native 1080p capable-display. Similarly, equipment capable of displaying both 720p and 1080i may in fact not have the capability to display 1080p or 1080i material at full resolution. It is common for this material to be downscaled to the native capability of the equipment. The term “native 1080p-capable” is sometimes used to refer to equipment capable of rendering 1080p fully.

HD ready

The label “HD ready” may not display the full picture resolution possible from an HD source. Most HD ready sets do not have enough pixels to give true pixel-for-pixel representation without interpolation of the higher HD resolution (1920×1080) – or (in rare cases) even the lower HD resolution (1280×720) horizontally (CRT based sets, or the plasma-based sets with 1024×768 resolution).

Note:

1. Obviously full HD is better choice but, this differentiation takes place (important) when the vision surface area is large at that moment you will saw major difference between full HD and HD ready.
2. HD movies and pictures depend on the input signal standards.
