Switch both Con0 to Con1 in you Config file. Con0 is your internal display which should be LVDS.

As for VGA, if it's not working OTB, then it's not supported.

By the way, your Config is missing the PlatformInfo Section

Hmm, the other E5470 I seen has HDMI on Con1, maybe your hardware is different, try setting Con2 as HDMI

it did not work with con2.
One thing to keep in mind is that I don't have a battery, the battery ran out, I don't know if it is influencing the hdmi configuration.

No it does not, does system have a discrete video card?

If so, that needs to be disabled via SSDT patching

Please post an IOReg file with IORegistryExplorer.app with HDMI connected
