Comment (by kallisti5):

 Actually, I had that backwards.

 The first connector sees a digital monitor and finds a digital EDID.
 (which is legit and makes it look like a valid attached digital monitor
 over TMDS).

 The second analog connector sees a valid analog EDID, however the card
 reports the encoder is unloaded (no display detected reading the analog
 channels)

 If you have a bunch of monitors attached, try detaching all but the VGA
 and reboot. Haiku's app server doesn't support multiple monitors at this
 time.
