ODROID-XU3/XU4 Tips

You can select the HDMI resolution by editing the boot.ini file. Just remove three “#” marks for your display.

The boot.ini file must be placed on the FAT partition on your boot media.

The default setting is 1920×1080(60hz).

Note: More distribution support will come with time.

HDMI support should work out-of-box for everyone including framebuffer console if you experience any issue please contact us on the ODROID Forums

On the provided Ubuntu image there are several examples on how to configure the HDMI to your specific resolution or even lock to a certain resolution. You can check the configuration file on /media/boot/boot.ini of the Ubuntu Image

For displayport configuration please follow this guide Displayport Guide on ODROID Forums
