Can all HDMI cables do 4K 60Hz?

The answer to this question is no, not all HDMI cables can support 4K 60Hz as it depends on the cable’s speed rating and bandwidth, with High Speed HDMI cables being the minimum requirement for achieving 4K resolution at 60Hz. To ensure a 4K 60Hz connection, it’s essential to choose an HDMI cable with a bandwidth of at least 18Gbps, which is typically labeled as High Speed or 4K-compatible.

Understanding HDMI Cables and 4K 60Hz

To understand why not all HDMI cables can support 4K 60Hz, we need to delve into the world of HDMI versions and their capabilities. The HDMI 2.0 standard, for instance, supports 4K at 60Hz, but older versions like HDMI 1.4 may only support 4K at 30Hz.

HDMI Versions and 4K 60Hz

The HDMI 2.1 standard offers even higher bandwidth and support for 4K at 120Hz or 8K at 60Hz. When it comes to 4K 60Hz, the HDMI cable must be able to handle the increased bandwidth required for this resolution and frame rate.
