  4K and 8K These are two standards for ultra-high-definition video resolution that make watching videos on a big screen awesome. The detail and quality of 4K or 8K videos are so high that they're almost like real life. You can enjoy these standards on many big-screen TVs, gaming consoles, and movie theaters. But what's the difference between 4K and 8K?
  What Is 8K Resolution?
  8K resolution is the ultimate video resolution today. It has 33.2 million pixels, which is fourfold more than 4K and sixteenfold more than Full HD. More pixels mean sharper and clearer images. With 8K, you can see every detail, even on a large screen or close up. You can also enjoy a wider viewing angle, as the pixels are smaller.
  But can you tell the difference between 4K and 8K? It depends on your screen size, distance, content quality, and eyesight. Generally, the bigger, closer, better, and sharper your screen is, the more likely you are to notice the difference.
  What Is The Difference Between 4K and 8K Resolution?
  While both 4K and 8K resolutions offer a vast improvement over their predecessors, the differences between them are noteworthy. Read more about the difference between 4K and 8K resolution below:
  Resolution: 4K has a resolution of 3840 x 2160 pixels for TV or 4096 x 2160 pixels for cinema. It is four times the resolution of Full HD. 8K has a resolution of 7680 x 4320 pixels for both TV and cinema. It is sixteen times the resolution of Full HD.
  Frame Rate: 4K has a frame rate of 50 to 60 frames per second (fps), while 8K has a frame rate of 120 fps. Higher frame rate means smoother motion and less blur.
  Audio Channel: 4K has an audio channel of 5.1, while 8K has an audio channel of 22.2. More audio channels mean more immersive sound and realism.
  Viewing Angle: 4K has a viewing angle of 55 degrees, while 8K has a viewing angle of 100 degrees. This means that 8k viewers can sit closer to the screen or view it from more extreme angles without experiencing visible pixelation or image degradation.
  What Do You Need To Stream 8K On Your TV?
  If you want to stream 8K on your TV, you will need several things:
  8k-Compatiable Devices
  To watch 8K content in its original state, you will need an 8K TV, an 8K monitor, or an 8K projector. Then you will need an 8K-compatible source, such as a Blu-ray player, a gaming console (Xbox or PS5), or a custom-built PC with Nvidia RTX graphics card. You can connect these devices to enjoy 8K content.
  Sufficient Bandwidth
  Secondly, to stream 8K online, you need enough bandwidth. Netflix says you need an internet connection of 25 Mbps or higher to stream 4K content. So, for 8K, you need at least 100 Mbps internet connection. These numbers may change depending on the platform, the content, and the compression.
  HEVC Support
  Another thing you will need to stream an 8K video online is HEVC support. HEVC stands for High Efficiency Video Coding: a video compression standard. It can shrink the size of an 8K video file by up to 50% without compromising much quality. This way, you can stream an 8K video online faster and smoother, and use less bandwidth and data.
  But not all devices support HEVC. Most of the newer devices, such as the latest TVs, monitors, streaming devices, Blu-ray players, and gaming consoles, have an integrated HEVC decoder. But some of the older devices, such as some laptops, tablets, smartphones, and computers, may have a restricted HEVC decoder that can only handle lower resolutions.
  HDCP-Compliant Adapters
  Lastly, you will need an HDCP-compliant adapter to stream an 8k video online. HDCP stands for High-bandwidth Digital Content Protection. It is a way to keep digital content safe from copying. To stream an 8k video online, you will need a device that works with HDCP 2.2 or higher, the latest kind of HDCP that can show 8K resolution.
USB-C Adapter
  One of the adapters that supports HDCP 2.2 or higher is the USB-C Adapter (8K HDMI). This adapter can connect your USB-C device to an HDMI display and support up to 8K resolution at 60 Hz or 4K resolution at 144 Hz. Another adapter that supports HDCP 2.2 or higher is the USB-C Adapter (8K DisplayPort). This adapter can connect your USB-C device to a DisplayPort display and support up to 8K resolution at 60 Hz or 4K resolution at 144 Hz, too.
