Actually we have three BBB boards, and two of them are perfectly displaying on our LCD screen with 1080@60 (I do not know why though, I have looked the lin <http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI>k that you send me Robert). All BBBs came with preinstalled linux 3.8.13-bone-70. On one that has display problem I reinstalled linux 3.8.13-bone41 accidentally and after than I upgraded to bone70. I am not sure If they have exactly same u-boot version. Is it ok, If I update you tomorrow?
