Worth pointing out is that DDC for external displays isn't working until my fixes for SDVO gets in there. Manually setting a mode works fine. Otherwise you'll default to 1280x1024 (or was it 1024x768?).

I suspect this is just DVI with a HDMI connector. That is the case for Fit-PC2. It is hooked up to the SDVO and provides video but no audio.
