Display

hdmi_enable_4kp60
# Raspberry Pi 4 Only

By default, when connected to a 4K monitor, the Raspberry Pi 4B, 400 and CM4 will select a 30Hz refresh rate. Use this option to allow selection of 60Hz refresh rates.

IMPORTANT
It is not possible to output 4Kp60 on both micro HDMI ports simultaneously.
WARNING
Setting hdmi_enable_4kp60 will increase power consumption and the temperature of your Raspberry Pi.
