Hello everyone,

I'm working on a project using the A20 SOM module and I would like to connect it to a [ur=http://www.waveshare.com/10.1inch-hdmi-lcd-b-with-case.html]waveshare 10" touchscreen[/url] display.
The problem I'm facing has to do with the specific resolution.
As the display has a resolution of 1280x800, I can't figure out how get this resolution out of the A20 SOM.
I've tried changing the script.bin(fex) file without any luck. I tried the framebuffer width and height and some other settings, but I couldn't get it outputting 1280x800.
I also tried using xrandr without any luck either.

Does anyone of you know how to get this exact resolution from the HDMI?

Thanks in advance
Laurens

i had the same problem with 7" monitor (800x480)
I used armbian 4.9  Armbian_5.25_Lime2_Debian_jessie_next_4.9.7
and external power, monitor connected to usb-hub and then to lime2, because this monitor need 5V~2A power supply
And everything will be okey.

I'd be happy when this helps.

sorry for my English :)
