This Mini DisplayPort to DVI-D Adapter allows you to connect a Mini DisplayPort or Thunderbolt equipped computer to a DVI-D monitor, projector or LCD. This allows you to use your existing DVI-D monitor with newer Mini DisplayPort devices. It is ideal for use 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 allows you to run multiple applications simultaneously on separate screens, improving productivity.
