DP是新接口標準，雖說可以轉接，但應該隻是向下兼容的：
-
HDMI (high definition media interface) is a newer port, but is 100% compatible with DVI. You can get cheap DVI->HDMI and HDMI->DVI cables and adapters (not converters, because there's nothing to convert). HDMI has the advantage of being able to carry an audio signal, but this only works if your card supports outputting HDMI audio and your monitor has built-in speakers can can receive audio over HDMI.
In 2009, HDMI 1.4 and subsequently 1.4a were introduced, with some significant changes from previous versions. These cables are backwards compatible, but add new features such as improved support for 3D displays, higher resolutions, and Ethernet over HDMI to allow for network connectivity on display devices. Most of these features will not affect the typical user, particularly when connected to a computer monitor, but are worth noting.
-
DisplayPort is the newest connector, and has only recently become available. Only newer and high-end monitors tend to have DisplayPort. There are converters from DP to other cables, but they require active converters which are sometimes less stable than a regular cable connection and can be expensive. Only use DisplayPort if both your monitor and graphics card support it, or if you have more than 2 monitors. If you have more than 2 displays, ATI graphics cards require that you use DisplayPort connectors for the third and any additional monitors.
-
Mini DisplayPort is electronically identical to DisplayPort, but has a smaller connector. It is common on higher end laptops, and is also found on some video cards. Mini DP has the same caveats as normal DisplayPort. Adapters for DisplayPort and Mini DP are not compatible, because of the size difference.
