While I haven't figured out why the X startup isn't recognizing
the current video mode, I have figured out that I can switch
between modes using XRandR:

1080P:
	root at nitrogen6x-lite:~# xrandr --size 1920x1080 --rate 60
720P:
	root at nitrogen6x-lite:~# xrandr --size 1280x720 --rate 60

There's probably also a way to set this up inside xorg.conf,
but I don't know the secret(s) yet.

Regards,


Eric
