The cable's 4K@240Hz capability does not mean the PS5 itself outputs games at 4K@240Hz; console output is limited by the console, game, and display.

HDMI 2.1 vs HDMI 2.0

Important Compatibility Note

To use advanced HDMI 2.1 features such as 4K@120Hz/144Hz/240Hz, VRR, or eARC, the connected source and display must also support the required HDMI 2.1 features.

For example:

PS5 + HDMI 2.1 Cable + HDMI 2.1 TV → 4K@120Hz possible

but:

PS5 + HDMI 2.1 Cable + HDMI 2.0 TV → limited by the TV's capabilities

The cable cannot increase the maximum resolution or refresh rate supported by the connected hardware.
