HD graphics are a type of graphic that is designed to have more pixels than the standard definition. HD stands for High Definition. This means that the picture is as “clear” and detailed as possible. HD doesn’t just refer to TV though, it also relates to computer’s monitor displays.
When you see a photo on your laptop or desktop, these pictures are most likely in HD quality. The higher the resolution of an image (or video) file, then generally the better looking the image will be from any viewing angle. This makes all images more crisp and clear than if they were not High Definition files with high resolutions.
Early HD resolution consisted of 1280×720 pixels or less than 2 megapixels (MP), making images look noticeably blurry due to the relatively low pixel density.
The first TV sets which displayed a 720p screen, appeared in 2007. 1080i became the standard from 2006 onwards followed by progressive scanning and high-definition digital television screens that showed 1920 x 1080 pixels per frame. However nowadays with more advanced cameras an average smartphone can shoot up to 12 MP at 4k resolutions, providing stunning results on a full HD 1080 display.
Any resolution greater than standard definition is considered high-definition or, more commonly, HD. It can mean 4k or 8k as well. To avoid confusion, 4K resolution – which is 3840×2160 – is typically called Ultra HD or UHD, while a 1920×1080 screen resolution might be termed as Full HD or FHD. HD is often understood as 1280×720 screen resolution.
