Apple's video strategy is not as 'custom' or 'proprietary' as you might think. It is extremely forward looking, though, and leads the greater market by 2-3 years.
Most Macs in the wild today have a Mini DisplayPort. It was developed by Apple, but later was adopted as a VESA standard and which Apple licenses free of charge. HP, Lenovo, Dell, Toshiba and others now have laptops on the market with Mini DisplayPorts.
Other video interfaces that have shown up on Macs are DVI (pre-2008-ish) and HDMI (Mac Mini only). Both, also industry standards.
The latest innovation from Apple was through Intel's "Thunderbolt" technology which takes the Mini DisplayPort and allows other peripheral devices to connect to it. It is completely backward compatible with Mini DisplayPort, so a new adapter is not required. Any standard Mini DisplayPort adapter or screen will work with it.
