I’m running an Odroid C2 and trying to drive a 14.9" 1280x390 60hz LCD marquis display. On a Pi I can change the boot config files to the following and the display works like a champ.
[HDMI:1]
hdmi_group=2
hdmi_mode=87
hdmi_timings=1280 0 8 128 64 390 0 1 3 24 0 0 0 67 0 42009500 8
On the Odroid running Armbian 22.11 Jammy XFCE I tried changing:
/boot/armbianEnv.txt
adding
display_autodetect=false
hdmimode=1280x390p60hz
I had no joy with this change, it did not modify the display output. I love how fast and light Odroid is with Armbian, it is really snappy, but I need some help stretching out this display. Any help pointing me in the right direction would be greatly appreciated, I already threw you $5 to take a look @Igor https://paypal.com/donate/?hosted_button_id=A2AM5NWLVENF2&source=url
