This Mini DisplayPort to HDMI Adapter allows you to connect a Mini DisplayPort or Thunderbolt equipped computer to a HDMI monitor, projector or LCD. This allows you to use your existing HDMI 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. Please note: For audio output to HDMI your Mini DisplayPort must support audio output via Mini DisplayPort. Contact your computer or graphics card manufacturer for further information.
