HDMI 2.1 standard supports up to 144Hz refresh over HDMI, including 120Hz with the latest consoles. The full 240Hz action is available only over DisplayPort 1.4 and need a GPU that supports Display Stream Compression (DSC). Any certified HDMI 2.1 cable will allow you the 144Hz rate.
Sorry, there was a problem. Please try again later.Any high-speed HDMI cable can reach up to 240hz, at least at 1080p.
