I had a problem that the wandboard did not recognize the resolution of my Sony 1600×1200 TFT display.
This issue seems to be on all screens I’ve tested when I used a HDMI-DVI converter.

By editing the file /etc/X11/xorg.conf you can set the resolution manually.
At the bottom of the file, you got a section thats called “Screen”

Change this to somthing like this, and change “Modes” to the resolution of your screen.

Section "Screen"
        Identifier      "Default Screen"
        Device          "Configured Monitor"
        Monitor         "i.MX Accelerated Framebuffer Device"
        DefaultDepth    24
        DefaultFbBpp    32
        SubSection "Display"
                  Modes "1600x1200"
         EndSubSection
EndSection

Just a tip, Hope it can come in handy 🙂
Take care & thanks for passing by…
