Understanding the Difference Between 4K and 8K Resolution

    Over the years, TVs have transformed from the big space-consuming boxes to become insanely slim. And It’s not just the physical size that has evolved; resolution, pictorial quality, audio quality, and frame rate are also evolving at a very fast rate.

    Technically, both 4k and 8k are ultra-high definition television (UHDTV) resolution, but the 8K resolution will display higher picture quality than 4K resolution and the image will be more delicate, it has a 100° viewing angle that will empower you to catch every frame and enjoy videos. Let’s go into full details of what to expect when 8K screens hit the market.

    Difference between 4k and 8k display

    In this article we talk about:


    The 8k display has a resolution of 7,680 (horizontal) pixels by 4,320 (vertical) pixels, while 4k has a resolution of 3,480 (horizontal) pixels and 2,160 (vertical) pixels. Compared to Full HD with 1920 (horizontal) pixels and 1080 (vertical) pixels, 4k is four-time its resolution while 8k has two times the resolution of 4k UHD.

    The 8k UHD has 33.3 megapixels, while the 4k UHD has 8.3 megapixels.

    Frame rate

    Frame rate refers to the total number of individual pictures that are displayed per second when viewing content on the TV-probably a Movie. The frame rate also affects video quality-higher frame rate means more natural motion can be captured from the movie.

    8k displays support up to 120 frames per second while 4k display supports 50 to 60 frames per second.

    Viewing angle

    Viewing angle is the maximum angle a person can view with optimal visual experience on the TV screen. The 4K display offers a 55-degree viewing angle, while the 8k displays offer a 100-degree viewing angle which allows you to watch videos from all visual angles possible.

    Audio channel

    An audio channel refers to an audio signal communications channel in a device from the source to the speakers.  The 8K Ultra HD supports 22.2 audio channel as opposed to the 4K Ultra HD that supports the 5.1 audio channel.
