If you own an Apple laptop then you'reprobably aware that despite their generally remarkable ease of use,these fantastic machines have one, persistent Achilles heel: theirvideo-out ports. For whatever reason, Apple can'tseem to decide on a single video interface for its notebooks and PCs.While this means that you, as a Mac owner, have to use some fancyfootwork in order to get the right adapter for displaying video datafromyour computer, this task is anything but impossible. Below,we'll look at some of the most common types of video ports used onApple laptops and the adapters you need to put these ports to work. Mini-DVI Asmaller variation of the DVI video connector, Mini-DVI allows you totransmit digital and analog video signals out from your laptop to anexternal display. The initials DVI stand for Digital Visual Interface.The DVI connector was originally developed as a digital alternative toanalog video connector schemes (most notably VGA), and because of itsunique genesis, the DVI connector is able to transmit both analog anddigital video. Apple has employed the Mini-DVIconnector on Intel-based iMacs and MacBooks, as well as on the MacMini-a 2009 desktop computer. A box, bordered on each side by verticallines, typically signifies a Mini-DVI port. This signifier is used byApple to designate Mini-DVI ports on its laptops and PCs. LikeI mentioned above, Mini-DVI ports are able to transmit both analog anddigital video signals. If you want to carry a video signal out fromyour Apple computer's Mini-DVI port, you can use one of severaladapters, depending on your specific needs. If you're going to betransmitting video to a monitor or projector with a VGA (Video GraphicsArray) analog video input, then you need a Mini-DVI-to-VGA adapter. If you're going to be transmitting video from your laptop to a digital display, then you're going to need a Mini-DVI-to-DVI adapter. Micro-DVI TheMicro-DVI connector is (surprise surprise) an even smaller variation ofthe Mini-DVI connector. Because of its small size, the Micro-DVIconnector doesn't have all of the features offered by the Mini-DVIconnector, so this connector type is typically used only in computerswhere space is at an absolute premium, such as in the MacBook Airlaptop computer. Micro-DVI ports are rectangular in shape and look very similar to a USB port. Micro-DVIports can transmit only digital video signals, as opposed to Mini-DVIports, which can transmit both digital and analog video signals. Thismeans that laptops with Micro-DVI ports are not compatible with VGAprojectors and monitors. However, you can still display a visual signalfrom your MacBook Air if you use a Micro-DVI-to-DVI adapter.This adapter will plug into your laptop's Micro-DVI port and carry asignal out from that port to a digital display that features aregularly sized DVI input. When looking forprojectors or monitors on which to display a signal from your MacBookAir, it is important to make sure that the input on these projects ormonitors is of the DVI-D variety. DVI connectors come in three types:DVI-I, DVI-A, and DVI-D. DVI-D connectors can transmit only digitalsignals, whereas DVI-A connectors can transmit only analog signals andDVI-I connectors can transmit both analog and digital signals. Becauseof its design, the Micro-DVI connector can transmit only digitalsignals and is therefore compatible with only DVI-D connector ports. Mini DisplayPort In2008, Apple announced that it would begin phasing out Mini-DVI andMicro-DVI connectors in favor of Mini DisplayPort connectors. As aresult, almost all MacBooks, Macbook Pros, MacBook Airs, and iMacsproduced later than 2008 employ a Mini DisplayPort interface for alltheir video-out needs. Mini DisplayPort connectorsoffer a higher level of video resolution than their Mini-DVI andMicro-DVI predecessors, and Mini DisplayPort jacks can carry audio anddata signals, as well as video signals. Designed as a replacement forthe various DVI and VGA connectors still cluttering the market,DisplayPort boasts the advantage of reverse compatibility with thetechnologies that proceeded it. This means that given a Mini DisplayPort-to-VGA adapter, a Mini DisplayPort-to-DVI adapter, or a Mini DisplayPort-to-DisplayPort adapter,you can display video from you laptop's Mini DisplayPort jack ontoalmost any kind of a projector or monitor.  The newest Apple computershave the "Thunderbolt" port which accepts Mini DisplayPorts. Theversatility of Mini DisplayPort makes it perhaps the most convenient ofApple's connector schemes to date. Now let's just hope they stick withit.
