P_20151104_085324.jpgWhen I power on my Sabre board with the HDMI monitor connected, all is well in the world.   I see a beautiful image on my monitor.


With the board still powered on, I disconnect the monitor.  On re connection, I will sometimes see this message on the serial terminal.


mxc_hdmi 20e0000.hdmi_video: Read EDID again

At this point the image on the monitor looks like it's out of sync with the source.  (I'm attaching the image)


There is no further EDID messages on the serial terminal after this  message.

Has anyone run into this issue before?  Does anyone know how to recover from this without cycling power to the board?  Does anyone know how to prevent this from happening?
