What is Full HD?
Full HD, also known as Full High Definition, refers to a high-definition display resolution of 1920×1080 pixels. This means that there are 1920 pixels horizontally and 1080 pixels vertically, resulting in a total of approximately 2.07 million pixels. This resolution is commonly used in modern TVs, monitors, and digital cameras.
Full HD is considered a high-definition resolution, but it is not as high as 4K resolution. While Full HD provides a clear and detailed image, 4K resolution has an even higher pixel density, resulting in a more detailed and lifelike image.
What is 4K?
4K resolution refers to a display resolution of 3840×2160 pixels. This means that there are 3840 pixels horizontally and 2160 pixels vertically, resulting in a total of approximately 8.29 million pixels. This resolution is commonly used in modern TVs, monitors, and digital cameras that require high-quality images.
4K resolution is considered ultra-high definition, providing an even more detailed and lifelike image compared to Full HD. The increased pixel density of 4K resolution results in a more immersive viewing experience, making it ideal for applications such as gaming, video production, and medical imaging.
Is 4K the same as UHD?
4K and UHD (Ultra High Definition) are often used interchangeably, but technically, they are not exactly the same. 4K refers specifically to a resolution of 3840×2160 pixels, while UHD is a broader term that can refer to resolutions higher than Full HD, including 4K.
In practice, however, UHD is often used to refer to 4K resolution, and many devices that support UHD also support 4K. So, while there is a technical difference between the two terms, they are often used interchangeably in the consumer electronics industry.
