Product name: HDMI male to male cable. Length: 30cm/1FT. This HDMI cable supports a range of higher video resolutions and refresh rates, including 8k 60Hz and 4k 120Hz, with resolutions up to 10K. It also supports high dynamic range HDR, and the bandwidth has been increased to 48Gbps It is used for extension and expansion between standard HDMI interface devices to realize real-time transmission of audio and video signals. Compatible with 8K@60HZ/4K@120HZ Dolby Vision & Dolby Sound, and compatible with lower resolutions, including 3840x2160, 2560x1600, 2560x1440, 1920x1200, 1080p, etc. HDMI 2.1 also adds multiple enhanced refresh rate technologies for videos, movies, and games, ensuring that users can use high resolutions smoothly without stuttering. For example: ? The "Variable Refresh Rate (VRR)" used in games can reduce the delay, lag, and tearing of the screen, allowing players to play the game more smoothly. ? There is also "Quick Media Switching (QMS)" for video and movies, which eliminates the delay that causes a blank screen before content is displayed. ? The "quick frame transfer (QFT)" is aimed at VR virtual reality, which greatly reduces the delay and makes the real-time interaction experience better. In addition, there is "Auto Low Latency Mode (ALLM)", in which the optimal delay can be automatically set. Both HDMI interfaces use 24K gold-plated interfaces and gold-plated pure copper conductors, which greatly improves signal transmission efficiency. The two interfaces do not distinguish between input and output, plug and play, the signal starts to transmit immediately, no need to drive the plug. Package Quantity: 1x8K Short HDMI 2.1 Cable
