====== Kodi on ODROID-C2: Adjust refresh rate ======
===== System Settings =====
1. Change the //hpd// option in ///media/boot/boot.ini// file. (**//"true"// -> //"false"//**)
  * /media/boot/boot.ini
<code>
# 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"
</code>
  
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
<code>
#!/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
</code>

3. Reboot
