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). One of the simple ways is to add chmod command into the /etc/rc.local file.

• /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
chmod 666 /sys/class/display/mode

if [ -f /aafirstboot ]; then /aafirstboot start ; fi

exit 0

3. Reboot

• SYSTEM → Settings → Video → Playback(Settings level >= Advanced) → Adjust display refresh rate
  • off → On start / stop or Always
