What is Full HD?

Both Full HD and 4K UHD represent the resolution of a display. Full HD resolution means there are true 1920 pixels in width and 1080 pixels in height. However, if you want to enjoy true HD images, you also need to connect the display to Full HD Blu-ray player via HDMI cable of course, a Blu-ray disc in Full HD format is necessary.

What is 4K UHD?

4K UHD refers to a horizontal screen display or image resolution of approximately 4000 pixels. The 4K UHD specification refers to one of two high-definition resolutions: 3840 x 2160 pixels and 4096 x 2160 pixels. After years of development, mainstream 4K UHD monitors support 3840×2160 pixels, and only a few products support 4096×2160 pixels.

What is the difference between 4k UHD and Full HD?

In fact, you can tell the difference between the old and new specs. As the resolution increases, the displayed image becomes more detailed. From a different perspective, we can more easily distinguish between 4K UHD and Full HD. A person’s horizontal field of vision is about 100 degrees. According to Full HD specifications. The horizontal resolution is approximately 1920, corresponding to a “32 degree” field of view. To get a larger angle of coverage, you need to shorten the distance between the eye and the image. The closer the eye is to the image, the easier it is to detect the pixel spacing, creating what is known as the “window glass effect.”
