The MEGA65's digital video output can also do HDMI-compatible audio (as confirmed via an Agilent N5998A HDMI protocol tester). However, some DVI monitors don't like seeing HDMI-style data islands, and refuse to show an image.
Ideally the MEGA65 would auto-detect this situation, presumably via EDID info block.
As a fall-back, we should support reading one of the mother board dipswitches to allow disabling the data islands to provide a pure DVI signal.
