The difference between HD and 4k is in the resolution. Resolution refers to the number of pixels, or dots, that make up the display on a screen. It is typically measured in terms of width and height. The higher the resolution, the sharper and more detailed the image or text will appear on the screen.
HD stands for high definition and refers to a resolution of 1920x1080 pixels. 4k, on the other hand, has a resolution of 3840x2160 pixels, which is four times that of HD. This means that 4k displays have higher pixel density, resulting in sharper and more detailed images.
Resolution comparison between SD (720x480) Full HD (1,920x1,080) 4K Ultra HD (3,840x2,160) 8K Ultra HD (7,680 by 4,320)
Whether it matters or not depends on various factors such as the size of the screen, viewing distance, and the content being displayed. For larger screens or closer viewing distances, the difference between HD and 4k becomes more noticeable. Additionally, if you are watching content that is specifically shot or mastered in 4k, you will benefit from the increased resolution.
However, if you are viewing content that is not optimized for 4k or if the screen size is smaller, the difference may not be as significant or even noticeable. Ultimately, the decision of whether it matters or not will depend on personal preferences and the specific use case.
Fun Fact!
4K images are 4,096 pixels across and 2,160 down. Multiply the width and height, and altogether this roughly adds up to an immense 8.3 million pixels!
