Why can’t I set the frequency to 240Hz on my monitor?
Please check the following solution :
- Make sure to use an HDMI 2.0 or DP 1.2a cable.
- If an HDMI 2.0 cable is used, make sure to connect to the correct HDMI 2.0 port.
- If a DP 1.2a cable is used, make sure to use the one bundled by BenQ.
- Make sure to update to the latest graphics card driver version.
- Make sure that your graphics card supports 240Hz.
