Noob issue: I have two brand-new SABRE-SD boards with i.MX6Q processors. Both have Android SD Cards. Nothing is modified. All fresh out of the box. Neither board will display on HDMI. I have tried 2 monitors and 2 HDMI cables. The monitors built-in firmware reports "no signal" on their input HDMI ports. The monitors and cables work on other computers so clearly there is no HDMI output from the SABER-SD. According to NXP/Freescale tutorial video the SABRE-SD is plug and play --- no configuration of the SABRE-SD is required to get HDMI output.
I'm stumped. Any ideas?
