TV manufacturers are improving picture quality, and 8K is the next big advancement in resolution. The resolution of an 8K TV is 7680 by 4320 pixels, marking an increase of another four times over 4K and 16 times the pixels of a 1080p or HDTV. The picture quality of an 8K TV is sharp and crisp, but the cost may inhibit buyers from rushing out to purchase one right away. TV manufacturers will likely continue to improve the 8K offering. If you choose an 8K TV, you'll need a few additional accessories. Video rated at 8K requires high speed to lead into the screen. You'll need at minimum 2.1 HDMI cables and a fast internet connection if you stream your content. HDMI 2.1 is a newer standard with a maximum bandwidth of 48Gpbs, three times the previous HDMI 2.0 capability.
