Two ideas to investigate:
* did you check with another more recent AGL release? (LL or master: Renesas
BSPs have different versions)
* any way to read DDC/EDID data using for example
[read-edid](http://www.polypux.org/projects/read-edid/)? Should work on ARM
boards, but never tested myself (or I don't even remember :) )

I have the same problem, regarding the required resolution is not available,
furthermore, the display is completely blank.
