In other words, 6,000 pixels can satisfy maximum horizontal field of view and the resolution of viewed images. The horizontal human field of view is around 100 degrees each degree can accept up to 60 pixels.

4K UHD cannot only bring a clearer and more natural image, but also deeply moves the audience.įrom a scientific perspective, we can tell the huge difference between 4K UHD and Full HD even more easily. The most impressive part is a more detailed image achieved by increased resolution. Once compared, you can tell the difference between the old and new specifications. “Do we really need Full HD? DVD quality is good enough though.” However, the truth is that the audience gets spoiled once they have experienced Blu-ray quality. Is there a big difference when viewing 4K UHD and Full HD movies? Actually, this is exactly the question people asked when the Full HD Blu-ray discs were just released. The more complete specifications you get, the more you can enjoy 4K content from a 4K player, USB file and an online video platform. These are all the specifications that you need to pay attention to when buying a 4K display.

For example, a HDMI 2.0 terminal (capable of transmitting 4K/60p signals), make sure that you use a USB player supporting H.265 high efficiency video coding (compared to H.264, the H.265 lowers the required traffic when playing 4K video) and a HDCP 2.2 as well as HDCP 1.4 compliant equipment (to play 4K videos with HDCP 2.2 copyright protection). If you wish the display equipment to fully correspond to 4K content, besides a 4K panel, you’ll also need to make sure if the related equipment can perfectly match. Through the developments over the years, major 4K UHD displays support 3840×2160 pixels and only very few products support 4096×2160 pixels. Take home displays for example, the 4K UHD specifications refer to one of two high definitions: 3840×2160 pixels and 4096×2160 pixels.

What is different from a Full HD is that the specifications of 4K UHD varies in professional fields and thus results in different definitions of horizontal pixels x vertical pixels. 4K UHD refers to a horizontal screen display or image resolution in the order of 4,000 pixels. This resulted in the phenomenon that all brands started to dedicate themselves to the development of 4K UHD products. Since mid-2013, the global imaging industry started to move to 4K and 4K UHD supporting displays were launched one after another.
