Re: [beagleboard] Re: BeagleBone Black - No HDMI Output
I've confirmed the cable isn't good. I plugged the cable into my Sony Ericsson Xperia Neo, there is output on my HDMI monitor. But nothing happens when connected to BBB. I know there are different versions for the HDMI spec. Do you mean I have to use the cable that supports newer version? honercek On Monday, September 30, 2013 10:01:37 PM UTC+8, Gerald wrote: > > OK.

I've updated BBB using the newest firmware, BBB-eMMC-flasher-2013.09.15.img. Still have the same problem.
