That's not what the standard says. They should be 100% compatible. The 
incompatibilities come about when trying to feed HDCP HDMI to non-HDCP DVI 
or vice-versa, or incompatible resolutions and/or scan rates.

Monitor capabilities are read from an EPROM (EDID) on DVI and HDMI systems; 
if the driver for the display adapter decides that the monitor can't support 
the desired display, it may decide to shut off video output. That can be 
another source of incompatibilities.
