To promote interoperability between DVI-D and HDMI devices, HDMI source components and displays support DVI-D signaling. For example, an HDMI display can be driven by a DVI-D source because HDMI and DVI-D both define an overlapping minimum set of supported resolutions and frame buffer formats. Some DVI-D sources use non-standard extensions to ...

Any DVI-to-HDMI adapter can function as an HDMI-to-DVI adapter (and vice versa). [56] Typically, the only limitation is the gender of the adapter's connectors and the gender of the cables and sockets it is used with.
There are three HDMI connector types. Type A and Type B were defined by the HDMI 1.0 specification. Type C was defined by the HDMI 1.3 specification. Type A is electrically compatible with single link DVI-D. Type B is electrically compatible with dual link DVI-D but has not yet been used in any products.
Like modern analog VGA connectors, the DVI and DisplayPort connectors include pins for DDC, but DisplayPort only supports DDC within its optional Dual-Mode DP feature in DVI/HDMI mode. The standard was created by the Video Electronics Standards Association (VESA).
On Channel 0 the C0 and C1 bits encode the Horizontal synchronization (HSync) and Vertical synchronization (VSync) signals. On the other channels they encode the CTL0 through CTL3 signals which are unused by DVI but in the case of HDMI are used as a preamble indicating the type of data about to be transferred (Video Data or Data Island), the HDCP status and so on.
