Kodi on ODROID-C2: Adjust refresh rate

1. Change the hpd option in /media/boot/boot.ini file. (“true” → “false”)

• /media/boot/boot.ini

# HDMI HotPlug Detection control
# Allows you to force HDMI thinking that the cable is connected.
# true = HDMI will believe that cable is always connected
# false = will let board/monitor negotiate the connection status
# setenv hpd "true"
setenv hpd "false"

2. Change /sys/class/display/mode file permission. (644 → 666)

$ sudo chmod 666 /sys/class/display/mode"
