How to Modify HDMI Output Parameters in Linux for ODROID-XU3 (Lite) Development Board

Good news, I’ve finally managed to make HDMI output in my ODROID-XU3 Lite development board work with the Ubuntu image after some more tweaking. So ODROID XU3 Lite Ubuntu review is coming in the next few days. But first, I’ll explain the few steps I went through, in case others experience a similar issue.

I downloaded, extracted, and flashed the latest Ubuntu image to a micro SD card with dd to give another try at running Ubuntu on my board, but no luck, I still got that black screen, albeit the system boots properly, as I got the command line using the serial console.

During my Android review of ODROID-XU3 Lite, I noticed the system would always revert back to 720p60 video output, and HDMI output settings can be selected in /media/boot/boot.ini with the following content:

I actually tried a few settings in my previous attempt but unsuccessfully. Now I know that 1080p does not work in Android with my TV, so I’ll focus on the 720p settings.

Trying 720p-edid, lead to a black screen, but enabling 720p-noedid worked around the issue, and I could finally see the LXDE desktop environment on my TV.  That means my TV (Panasonic TH-L39EM6T) and ODROID-XU3 Lite board have issues communicating EDID information, and it’s most probably a driver issue that needs to be fixed, but at least, if you encounter a black screen with your board, it’s worth spending some time trying all options in boot.ini.
