Hey guys, I've got a screen here, it's 1280x800. Specifically it's the ODROID-VU.
I've also got 2 beaglebone blacks. Both are RevC. One is on 3.8.13-bone47 so factory and the other is on 3.8.13-bone70 so latest.

Thing is the factory board shows up on my screen just fine while my updated one does not. I tested my cable and latest board on a 9" with the same resolution and it seems to work just fine so it's not the cable or the connector.
xrandr on both the working and non working come back with "Can't open display" 
I tried adding video=HDMI-A-1:1280x800@60 to /boot/uEnv.txt and nothing happened

At this point I really don't know what to do, nor do I know where to get the factory image.

Any ideas?

How about:

video=HDMI-A-1:1280x800@60e
