This looks like a pretty standard set of modes for a
4:3 aspect ratio monitor.

This doesn't match one of the CEA modes:
https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_3.0.35_4.1.0/drivers/video/mxc/mxc_edid.c#L41
Can you boot with this command-line argument?
mxc_hdmi.only_cea=0
I think you'll either need that or you'll need to choose a
display resolution from the list. It appears that your monitor
and CEA both like 1280x720@60, though you'll likely get
letter-boxing.
Regards,
Eric
