What is Full HD – Difference between HD Ready and Full HD resolution
Finding the right device can be a daunting task, especially when you're bombarded with terms like Full HD, Ready HD, 4K Ultra HD, and so on. What do these letters mean? If you are not aware, do not worry! This article will explain what is Full HD and the difference between HD ready and Full HD resolution.
High definition or HD, the new reference standard for image resolution is often used interchangeably with "Full HD" to describe the image resolution of a product – but this has only confused. Let's try to clarify that. The concept of HD has completely changed the level of visual detail and clarity that we expect from our screens.
What is Full HD?
Full HD is a term used to refer to the resolution of the TV screen. This basically means an image with a resolution of 1920 x 1080 pixels. The measurement of the number of pixels is carried out by estimating the height and the width. Thus, if a display unit such as TV has a resolution of 1920 x 1080p, it means that its height is 1080 pixels and its width is 1920 pixels and the total number of pixels that this resolution can support is 1920×1080 = 2073600 pixels. The higher the number of pixels, the better the quality of the image, because the number of combined pixels composes an image on the TV. This resolution is commonly seen on widescreen TVs or 16: 9 monitors.
At the upper end of the spectrum, there is Ultra HD (UHD or 4K). This image resolution is bigger, sharper and sharper than even in 1080p. However, the Ultra HD image resolution has not yet been adopted universally. Why? Although technically, "4K" refers to a horizontal resolution of pixels containing 4096 pixels, no vertical resolution is specified for this resolution. Thus, Ultra HD TVs are not technically 4K.

Difference between HD Ready resolution and Full HD resolution
Primarily, the difference between HD Ready resolution and Full HD resolution refers to the actual size of the image. HD can refer to 720p or 1080p, but Full HD can only refer to 1080p. On the other hand, the HD Ready expression refers to only 720p. Thus, when the term 'HD Ready' is used to describe a TV or monitor / laptop / PC, it means that the camera has an image resolution of 720p. The term "HD" can also be used. As such, the HD Ready image resolution will contain 720 lines of pixels along the vertical axis and 1,280 lines of pixels along the horizontal axis, which will give the 39, image a height of 720 pixels and a width of 1280 pixels.
This will result in a total number of pixels of 921,600, the lowest resolution image can be considered high definition.
In addition, the Full HD resolution corresponds to a height of 1080p and a width of 1920 pixels. This gives a total number of pixels of about 2 million pixels in total.
The more pixels in an image, the better, because more pixels in each area will allow an image to contain little or no visible pixels (known as retina display), which allows for clearer details and clarity. In a retinal display, there are more pixels in a specific area than the human eye can see individually.
