Both 4K and 8K are ultra-high definition television (UHDTV) resolution in digital television and digital cinematography. They are advanced Super Hi-Vision (SHV) TV video technology and considered to be the next generation TV video processors.

 

Consumers commonly mistake 8K and 4K to be the equivalent of 1080p and 720p resolution. While they produce impressively high-quality video, there is a considerable difference between 4K and 8K video in terms of UHDTV resolution.

 

Let’s break down each element of both to help you decide which is best for you depending on your home theater or media room viewing needs.

4K vs 8K - Specifications:

Resolution

●        4K has 3840 x 2160 pixels mainly for Ultra HD television, or 4096 x 2160 pixels for digital cinema. 4K Ultra HD is exactly four times of the resolution of Full HD.

●        8K is a resolution of 7680 x 4320 pixels. 8K Ultra HD is sixteen times the resolution of Full HD, and four times of 4K Ultra HD.

 

The higher the pixel counts within a digital image, the sharper the image displays. For instance, if you view a Blu-ray movie without changing resolution on an 8K TV, the screen will only take up 1/16 of the screen, as Blu-ray always stores video in 1080p. It does this to maintain the sharpness of the image. The same happens If you play 4K videos on 8K TV. The image cannot be played in full screen but will maintain a smaller screen to retain a sharp image.

Total Pixels

●        4K Ultra HD has 8 million pixels.

●        8K has 33 million pixels.

 

The dots on a TV are referred to as Pixels. A pixel is defined as a picture element. Each pixel contains red, green, and blue color information. This total of all pixels is referred to as Pixel Density.

 

Frame Rate

●        4K Ultra HD has a frame rate of 50 fps or 60 fps.

●        8K Ultra HD has 120 fps.

 

Frame rate refers to the number of individual frames or images that are displayed per second in a movie, computer game display or TV. It is widely used in synchronizing audio and pictures. A common argument claims that the higher the frame rate is, the more natural the motion that you can capture from the movie.

Standard Viewing Angle

●        Viewing angle of 4K Ultra HD is 60°.

●        Viewing angle of 8K Ultra HD is 100°.

 

Viewing angle is the maximum angle that you can view while maintaining acceptable visual performance on the monitor. 8K TV allows you to watch videos at greater visual angles.

Audio channels

●        Audio channel for 4K Ultra HD is 5.1.

●        The audio channel for 8K Ultra HD is 22.2.

 

Both 4K and 8K Televisions will require a standard speaker setup for optimal audio. The setup includes speakers in the front center, left, right, and rear of the room. You will also place subwoofers in the front of the room.
