The adapter cable shown in Figure 12.8 is not designed to work with graphics cards and
drivers that do not support HDTV resolutions and timings. You may need to upgrade your

DVI ports, this type of adapter cable is only intended for PC-HDTV connections.
Starting in late 2006, some vendors began to release PCIe cards including HDMI ports.
Some provide HDMI input and output for use with HDV camcorders, whereas others us-
ing ATI or NVIDIA chipsets are graphics cards that also include HDMI output. Although
HDMI is a royalty-based interface, requiring an annual license fee of $10,000 plus a pay-
ment of 4 cents per device, and the newer DisplayPort interface is royalty-free, HDMI
continues to be used on a wider range of current video cards and systems with integrated

such as the one shown in Figure 12.1 , use the mini-HDMI (HDMI Type C) connector to
save space on the card bracket.

DisplayPort
DisplayPort is the latest digital display interface standard. It is designed to replace VGA,
DVI, and HDMI for use in PCs and to coexist with HDMI in consumer electronics
devices. Dell originated the design in 2003 and then turned it over to VESA in August
2005. In May 2006, VESA published it as an open industry standard.
DisplayPort is designed to replace all the previous digital and analog interfaces, including
DVI, HDMI, and even VGA. In addition, it is a royalty-free interface and does not incur
the licensing fees of HDMI or the implementation patent fees of DVI. Also, DisplayPort
is designed both as an internal and an external interface, meaning it can replace the FPD-
