【8K Optical Fiber HDMI Cable】8K optical fiber HDMI cable is evolving rapidly; it realizes ultra-long-distance audio and video transmission, without signal compression, no delay in light speed transmission, no electromagnetic interference, and no radiation. It is compatible with 8K@60HZ and 4K@120HZ, clearly displays every particle, and accurately processes every signal source.

【Upgrade Revolution----HDMI 2.1】 Highwings 8K HDMI Cable conforms to the standard HDMI 2.1 version. Compared with HDMI 2.0, its transmission speed has a qualitative leap, from 18Gbps to 48Gbps (6GB/s) directly, and there will no longer be stuck or dropped frames when watching video from now on. Support eARC, can achieve more advanced audio signal control capabilities. It is also backward compatible with HDMI

【HDMI Cable For Game Enthusiasts】 This HDMI Cable is not limited to 4K@60HZ, it can break through 4K and achieve 8K ultra-high image quality. It can also achieve a super smooth picture of 4K@120HZ. Its latest game mode supports variable refresh rate, maximizes the value of the graphics card and CPU, and is more accurate in the processing of rendered images. When the scene is switched, the refresh rate will change accordingly to obtain a smoother and more detailed picture.

【Reinforced classic high-quality materials】 This 8K HDMI Cable uses Highwings' most popular classic style, with a new smart chip, making it reach an unprecedented height. The strength of the aluminum alloy shell and the tail's anti-bending design has been upgraded to make it more durable. The plug part is still made of 24K gold-plated material, which accurately transmits signals. The military grade tensile nylon material also greatly extends its life.

【Unidirectional Transmission】Highwings Fiber Optic HDMI Cable is the unidirectional transmission. The plugs at each end are marked ✨【SOURCE/DISPLAY】✨, please note that source is the signal source (laptop, PC, ps4/ps5, Xbox and Blu-ray player, etc) and the display is the display end (monitor, TV, projector, etc).
