Conguring Linux
After booting the ODROID to a Linux desktop, the screen reso-
lution should rst be updated to match the refresh rate of the monitor.
To do so, edit the /media/boot/boot.ini le located on the Linux boot
partition using a text editor:
$ nano /media/boot/boot.ini
After the le has loaded, uncomment the following lines after comment-
ing out the current selections. In the following example, the 1080p
resolution at 60hz refresh rate has been selected, which is the default
conguration on rst boot:
# Possible screen resolutions
# Uncomment only a single Line! The line with setenv written.
# At least one mode must be selected.
# 480 Lines (720x480)
# setenv m “480i60hz” # Interlaced 60Hz
