BeagleBoard verification


I am Srujan from UHCL I have a new Beagle board I tried to verify it I
connected the USB-OTG cable to power it and a monitor through HDMI-
D cable I saw the LEDs glow but I did not see anything on the monitor
I waited for soo long but nothing came up, the monitor is working
though, can you tell me whats the problem or do you have any reference
that I can check in the manual or any website??

Thank you.
