Beagleboard with Angstrom and LCD

I have a BeagleBoard C4. I am trying to run Angstrom. Connected an LCD with HDMI to DVI-D (normal HDMI can’t work?). But the screen stays black!
In the serial console i can see the Angstrom booting, it asks for login etc…

What can be wrong?

Can you post the head part of /boot/uboot/uEnv.txt file?
Normally, it should contain something like below, you can change the resolution (ex 1280x720) to fit your LCD screen.


By the way, what version of Angstrom do you have? A minimal package or with GUI?
