If your computer supports 4K@60Hz, while your monitor/TV only supports 4K@30Hz or 1080p, you can only output 4K@30Hz or 1080p rather than 4K@60HzMacBook 12" does not support 4K@60Hz output; it has a maximum output of 4K@30Hz.An HDMI 2.0-compliant cable is required as utilizing the highest resolution 3840x2160@60Hz. HDMI 1.4/1.3 cables will likely result in a blank screen, digital noise, or display drop-offs.For certain monitors may turn on and off every minute as connected with a long HDMI cable, for stable output, we highly recommendusing a short HDMI cable within 5.9ft to connect your display.
