CRT displays
In the very beginning (throughout the 1970's) Apple did not manufacturer or sell displays of any kind, instead recommending users plug-into their television sets or (then) expensive third party monochrome monitors. Apple's history with CRT displays only began in 1980, starting with the Monitor III that was introduced along side the Apple III business computer. It was a 12" monochrome (green) screen that could display 80x24 text characters and any type of graphics, however suffered from a very slow phosphor refresh that resulted in a "ghosting" video effect. So it could be shared with Apple II computers, a plastic stand was made available to accommodate the larger footprint of the monitor. Image:Apple Monitor II.jpg Roughly 4 years later came the introduction of the Monitor II, which as the name implies, was more suited in look and style for the Apple II line and at the same time added improvements in features and visual quality. In 1984 a miniature 9" screen, called the Monitor IIc, was introduced for the Apple IIc computer to help complement its compact size. By early 1985 came the first color CRT's, starting with the Monitor 100, a digital RGB display for the Apple III and Apple IIe (with appropriate card), followed shortly by the 14" ColorMonitor IIe and ColorMonitor IIc, composite video displays for those respective models. Image:Applecolor RGB Monitor.jpgIn 1986 came the introduction of the AppleColor RGB, a 12" analog RGB display designed specifically for the Apple IIGS computer. It supported a resolution of 640x400 interlaced (640x200 non-interlaced) and could be used by the Macintosh II, in a limited fashion, with the Apple High Resolution Display Video Card. Also introduced that year was the Apple Monochrome Monitor, which cosmetically was identical to the former screen but was a black and white composite display suitable in external appearance for the Apple IIGS, Apple IIc or Apple IIc Plus.
The second generation of displays were built into the Apple Macintosh line of computers. Back then the Macintosh had a high resolution 9-inch monochrome monitor that could display 512x342 pixels. All future models of the Classic style Macintosh later featured this exact display. New external Apple Displays were introduced in 1987 with the Macintosh II. The Macintosh II had a PC-style expandable case which required an external monitor, it was also able to run up to six external displays simultaneously using multiple video cards. The desktop spanned multiple monitors and windows could be dragged from monitor to monitor, or even straddle two or more. The Color 12", 16" and 21" displays were introduced with resolutions of 512x384, 832x624 and 1152x870. Also monochrome displays were introduced mainly for the publishing industry, like the Macintosh Two Page Monochrome Monitor which was able to display pages next to each other with identical resolution to the 21" color one. Also the Macintosh Portrait Display was introduced which had a vertical aligment of the screen and was able to display one page. A 12" monochrome version was also introduced at the low end.
The third generation of displays were introduced in the form of the Macintosh Color Display in 1992 and was the first Apple display to feature a Trinitron, or aperture grille, CRT. The first display to include built-in speakers was introduced in 1994 as the AudioVision 14". Monitors were divided into two groups. There were the cheaper Multiple Scan monitors with standard shadow mask CRTs with fewer colors and lower resolution. There was also the AppleVision series of displays which were positioned to the professional market and included more expensive Trinitron CRTs. Many models didn't include built-in speakers because they were considered toys by some in the publishing industry. The AppleVision line of displays were later renamed as ColorSync displays when Steve Jobs returned to Apple and consolidated the product lines. Only 17" and 20" models were left in the product line.
The fourth generation of displays were introduced simultaneously with the Blue & White Power Macintosh G3 which included the translucent plastics (initially white and blue, then white and grey upon the introduction of the Power Mac G4) of the iMac. The displays were also designed with same translucent look. The Apple Studio Display series of CRT displays were available in 17" and 21" models, both using Trinitron CRTs. The last Apple CRT was introduced in 2000 along with the Power Mac G4 Cube. It featured clear plastics to match the Cube and LCD Studio Displays, a flat screened Diamondtron CRT, and the new Apple Display Connector, which provided power, USB, and video signals to the monitor through a single cable.
LCD displays
Image:Apple IIc Flat Panel Display.jpg The history of Apple LCD displays started back in 1984 when the Apple Flat Panel Display was introduced for the Apple IIc computer. The display had an odd aspect ratio (making images look vertically squished) and required a very strong external light source, such as a desk lamp or direct sunlight to be used. Even then it had a very poor contrast overall and was quite expensive, contributing to its poor sales and consequently it dropping from the market not long after its introduction.
The next flat-panel was introduced on March 17, 1998 with the 15" Apple Studio Display which had a resolution of 1024x768. After the eMate, it was one of the first Apple products to feature translucent plastics, many months before the unveiling of the iMac. It had a DA-15 input as well as S-video, composite video, ADB and audio connectors, though no onboard speakers. In January 1999 the coloring was changed to match the blue and white of the new Power Macintosh G3s, and the connector changed to VGA.
The 22" widescreen Apple Cinema Display was introduced in August 1999, simultaneously with the Power Mac G4 and in the beginning was sold only as an option to the Power Mac G4, selling for $3,999. It had a native resolution of 1600x1024 and used a DVI connector. The display had a striped look on the bezel, similar to previous Studio Displays and iMacs. In December, the colors of the 15" display were changed to match the new Power Mac G4s, and the input was changed from VGA to DVI, the audio and video features dropped, and the ADB functionality replaced by a two-port USB hub.
In 2000 the 22" Cinema Displays switched to the ADC interface, and the 15" Studio Display was remodeled to match the Cinema Display's easel-like form factor and also featured the Apple Display Connector. In 2001 an LCD-based 17" Studio Display was introduced, with a resolution of 1280x1024. In 2002 Apple introduced the Cinema Display HD which had a 23" widescreen display with a resolution of 1920x1200. In 2003 Apple introduced the 20" Cinema Display to replace the now discontinued 22" display and it had a resolution of 1680x1050.
Image:Dual apple monitors.jpg In 2004 a new line was introduced, utilizing the same 20" and 23" panels alongside a new 30" model, for $3,299. The displays had a sleek aluminum enclosure with a much narrower bezel than their predecssors. The 20" model has a 1680x1050 resolution, the 23" has 1920x1200, and the 30" has 2560x1600. The 30" version requires a dual-link interface, because a single-link DVI connection (the most common type) doesn't have enough bandwidth to provide a picture to a display of this resolution. Apple sells the new NVIDIA Quadro FX 4500 as an option to the Power Mac G5. The card includes two dual-link DVI connectors which allows a Power Mac G5 to run two 30" Cinema Displays simultaneously with the total number of pixels working out at 8.2 million.
Connectors
Apple has employed a large number of display connector designs over the years:
- Original DA-15 (commonly but incorrectly known as a DB-15) used on all desktop Macs without a built in monitor up until the 1999 Blue and White Power Macintosh G3.
- A 13W3 connector (as on Sun Microsystems machines) used on the Macintosh Portrait Display
- A non-standard "mini-15" connector used on early PowerBooks which allowed an Apple monitor to be attached via a short adaptor cable.
- Apple MultiMedia Display connector (HDI-45) used on some "AV" model Centris, Quadra and Power Macintosh 6100 machines.
- Standard 15-pin high-density D VGA connector, first included on some Power Macintosh 9600 models and available on all current Macintoshes either directly or via a short adaptor cable.
- Standard DVI connector, which can also provide VGA via a short adaptor cable, and composite and S-Video in the Power Mac G5 and Mac mini.
- Apple Display Connector, which carries DVI, VGA, USB and power in one connector.
- A mini-VGA connector, which can provide VGA via a short adaptor cable. It appears on the white iBook, eMac, iMac G4 and G5, and first generation 12-inch PowerBook G4. Later models also support a composite and S-video adapter attached to this port.
- A mini-DVI connector used on the 12" PowerBook G4 (except first generation) which provides DVI, VGA, or composite and S-video, via short adaptor cables.
Additionally, various Macs have been able to output:
- S-video via standard 4-pin mini-DIN connector
- Composite video, via:
- S-video port and use of short adaptor cable (PowerBooks)
- Standard phono connector (AV Macs)
- A non-standard 3.5mm jack that functions as either a headphone jack, or stereo audio and composite video out via an adaptor cable (FireWire Special Edition Clamshell iBooks and early "Dual USB" iBooks with external reset button)
- S-video, Composite, or VGA, via:
- Mini-VGA when using an Apple Video Output Adapter (S-video & Composite or VGA)
- The Apple Video Adapter was specially designed to allow users to connect to S-video or composite video devices. The video adapter cable plugs into the video output port (Mini-VGA) built into the back of certain Macintosh computers. The video output port supports VGA, S-Video and Composite video out. The Apple Video Adapter is for S-Video or Composite video output only, use a separate Apple VGA Adapter for VGA video output options. With the Apple Video Adapter you can connect to your TV, VCR, or overhead projector via S-Video or Composite cables.
Compatible with: iBook without an external reset button, 12-inch PowerBook G4, Mac Mini, eMac, iMac G5, or 17-inch iMac (1GHz) with Mini-VGA port.
- The Apple VGA Display Adapter was specially designed to allow users to connect certain Macintosh computers to an extra VGA monitor or external projector (equipped with VGA) for 24-bit video-mirroring. The VGA cable from your external monitor or projector cable plugs into the Mini-VGA video port built into your Macintosh via the Apple VGA Display Adapter.
Compatible with: eMac, iMac G5, iMac G4 flat-panel, 12-inch PowerBook G4, or iBooks having a Mini-VGA port. Most Macintosh computers with the Mini-VGA port can also use the Apple Video Adapter for S-video & Composite output options.
- 12-inch PowerBook G4 (first generation) models support video-mirroring and extended video desktop modes which enables you to have a dual-display setup on your 12-inch PowerBook G4. 15 and 17 inch PowerBook G4 models have a Mini-DVI port which later replaced the Mini-VGA port on the second generation 12-inch PowerBook G4 models.
