The Micro-DVI port is a proprietary video output port introduced on the original MacBook Air in 2008. It is smaller than the Mini-DVI port used by its MacBook models.
To use the port for displaying video on a standard monitor or television, an adapter must be used. Both a Micro-DVI to DVI adapter and a Micro-DVI to VGA adapter were bundled with the original MacBook Air. A Micro-DVI to Video adapter, which provided composite and S-video outputs, was also sold separately. The Micro-DVI to DVI adapter is only compatible with a DVI-D (digital) signal; DVI-A and DVI-I signals do not work as they do not have the required analog connections.
The Micro-DVI connector was replaced with the Mini DisplayPort connector starting with the Late 2008 MacBook Air, making it one of the shortest lived connectors created by Apple.
Additionally, the Asus U2E subnotebook includes a "Micro-DVI" port, [1] which unlike the Apple version has the same form factor as HDMI.
Although it is electrically compatible with HDMI, it does not provide audio output.
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content.
S-Video is an analog video signal format that carries standard-definition video, typically at 525 lines or 625 lines. It encodes video luma and chrominance on two separate channels, achieving higher image quality than composite video which encodes all video information on one channel. It also eliminates several types of visual defects such as dot crawl which commonly occur with composite video. Although it is improved over composite video, S-Video has lower color resolution than component video, which is encoded over three channels.
Apple Inc. has sold a variety of LCD and CRT computer displays since introducing their first display in 1980. Apple paused production of their own standalone displays in 2016 and partnered with LG to design displays for Macs. In June 2019, the Pro Display XDR was introduced, however it was expensive and targeted for professionals. In March 2022, the Studio Display was launched as a consumer-targeted counterpart. These are currently the only Apple-branded displays available.
The Apple Display Connector (ADC) is a display and data connector developed by Apple, Inc. as a proprietary modification of the DVI connector. ADC combines analog and digital video signals, USB, and power all in one cable. It was used in later versions of the Apple Studio Display, including the final 17" CRT model, and most versions of the widescreen Apple Cinema Display, after which Apple adopted standard DVI connectors on later models.
High-Definition Multimedia Interface (HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards.
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, as well as many monitors, projectors and HD television sets.
Mini-VGA connectors are proprietary and non-standard alternative video connectors that were used on some laptops and other computer systems in place of a standard VGA connector. Apple, HP, and Asus each introduced separate connectors using the same moniker of "mini-VGA", but which are otherwise physically incompatible with each other.
The Apple Cinema Display is a line of flat-panel computer monitors developed and sold by Apple Inc. between 1999 and 2011. It was initially sold alongside the older line of Studio Displays, but eventually replaced them. Apple offered 20, 22, 23, 24, 27, and 30-inch sizes, with the last model being a 27-inch size with LED backlighting.
A composite monitor or composite video monitor is any analog video display that receives input in the form of an analog composite video signal to a defined specification. A composite video signal encodes all information on a single conductor; a composite cable has a single live conductor plus earth. Other equipment with display functionality includes monitors with more advanced interfaces and connectors giving a better picture, including analog VGA, and digital DVI, HDMI, and DisplayPort; and television (TV) receivers which are self-contained, receiving and displaying video RF broadcasts received with an internal tuner. Video monitors are used for displaying computer output, closed-circuit television and other applications requiring a two-dimensional monochrome or colour image.
DisplayPort (DP) is a proprietary digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data.
DMS-59 was generally used for computer video cards. It provides two Digital Visual Interface (DVI) or Video Graphics Array (VGA) outputs in a single connector. A Y-style breakout cable is needed for the transition from the DMS-59 output to DVI (digital) or VGA (analogue), and different types of adapter cables exist. The connector is four pins high and 15 pins wide, with a single pin missing from the bottom row, in a D-shaped shell, with thumbscrews. As of December 2020, this adapter cable was listed as obsolete by its primary vendor Molex.
The Mini-DVI connector is used on certain Apple computers as a digital alternative to the Mini-VGA connector. Its size is between the full-sized DVI and the tiny Micro-DVI. It is found on the 12-inch PowerBook G4, the Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, the 2009 Mac mini, and some late model eMacs.
Mobile High-Definition Link (MHL) is an industry standard for a mobile audio/video interface that allows the connection of smartphones, tablets, and other portable consumer electronics devices to high-definition televisions (HDTVs), audio receivers, and projectors. The standard was designed to share existing mobile device connectors, such as Micro-USB, and avoid the need to add video connectors on devices with limited space for them.
Mac Mini is a small form factor desktop computer developed and marketed by Apple Inc. As of 2022, it is positioned between the consumer all-in-one iMac and the professional Mac Studio and Mac Pro as one of four current Mac desktop computers. Since launch, it has shipped without a display, keyboard, and mouse. The machine was initially branded as "BYODKM" as a strategic pitch to encourage users to switch from Windows and Linux computers.
The Mini DisplayPort is a miniaturized version of the DisplayPort audio-visual digital interface.
Audio connectors and video connectors are electrical or optical connectors for carrying audio or video signals. Audio interfaces or video interfaces define physical parameters and interpretation of signals. For digital audio and digital video, this can be thought of as defining the physical layer, data link layer, and most or all of the application layer. For analog audio and analog video these functions are all represented in a single signal specification like NTSC or the direct speaker-driving signal of analog audio.
The Apple Thunderbolt Display is a 27-inch flat panel computer monitor developed by Apple Inc.and sold from July 2011 to June 2016. Originally priced at $999, it replaced Apple’s 27-inch Cinema Display. For displays it can only connect with computers with a Thunderbolt port. It is incompatible with most non-Apple computers, along with Macs released before 2011 and the 2012 Mac Pro or the single USB-C Retina MacBook. Devices with Thunderbolt 3 using an adaptor will work with the Apple Display.
USB-C, or USB Type-C, is a 24-pin connector that supersedes previous USB connectors and can carry audio, video, and other data, e.g., to connect to monitors or external drives. It can also provide and receive power, to power, e.g., a laptop or a mobile phone. It is used not only by USB technology, but also by other protocols, including Thunderbolt, PCIe, HDMI, DisplayPort, and others. It is extensible to support future protocols.
AMD Eyefinity is a brand name for AMD video card products that support multi-monitor setups by integrating multiple display controllers on one GPU. AMD Eyefinity was introduced with the Radeon HD 5000 series "Evergreen" in September 2009 and has been available on APUs and professional-grade graphics cards branded AMD FirePro as well.
