This Mini Display Port to DVI-D Adapter means that you can connect a Mini Display Port or Thunderbolt equipped computer to a DVI-D monitor, projector or LCD. This means that you can use your existing DVI-D monitor with newer Mini Display Port devices. It is ideal to be used in established digital entertainment centres, home offices, conference rooms or advertising displays. It also supports AMD Eyefinity technology which gives you a cost effective way of creating a non-standard aspect ratio or ultra-high resolution display made up from up to 3 or more monitors. This feature also means that you can run multiple applications simultaneously on separate screens, improving productivity.
