Apple Mini DisplayPort to DVI Adapter
The Apple Mini DisplayPort to DVI Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to a display that uses a single-link DVI cable.
This adapter supports display resolutions up to 1920 x 1200.
Apple Mini DisplayPort to Dual-Link DVI Adapter
The Apple Mini DisplayPort to Dual-Link DVI Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to a display that uses a dual-link DVI cable.
This adapter supports display resolutions up to 2560 x 1600. To use it with a dual-link DVI display such as the 30-inch Apple Cinema HD Display, connect the USB cable from the display to the USB-A port 
on the adapter, then connect the USB-A cable on the adapter to the USB-A port on your Mac.
Apple Mini DisplayPort to VGA Adapter
The Apple Mini DisplayPort to VGA Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to display that uses a VGA cable.
This adapter supports display resolutions up to 1920 x 1200. To achieve resolutions greater than 1600 x 1200, displays with high refresh rates might require that you lower the refresh rate.
Because the VGA connection is analog instead of digital, HDCP-encrypted content might not play back, or might play back at a lower resolution.
