According to the specification, the HDMI 2.1 cable from Digitec supports a bandwidth of up to 48 Gbps, which is theoretically sufficient for 4K at 240 Hz. However, the available information specifically mentions 1440p at 360 Hz as an example, not explicitly 4K at 240 Hz. The HDMI 2.1 standard itself allows 4K at 240 Hz, but the actual support also depends on the cable quality and the connected devices.
