The Atlona AT-HD620 HDMI + Mini-DisplayPort (MDP) to MDP with Stereo Audio scaler and switcher box allows the user to extend the usage of their Mini DisplayPort monitor. This device can convert HDMI signals from any HDMI enabled source (BluRay, PS3, Xbox, Cable Box, TiVo and so on) to a Mini DisplayPort monitor. The scaler is able to upconvert any HDMI resolution to match the native resolution of an Apple iMac 27” (2560x1440) and Apple 24” (1920x1200). The scaler is capable of scaling up to dual link resolutions. The AT-HD620 will perfectly work with other Mini DisplayPort and DisplayPort monitors as well. The switching abilities of the AT-HD620 allows users to have HDMI sources as well as Mini DisplayPort sources connected at the same time and switch between them rather than disconnecting and reconnecting cables each time a user wants to view HDMI sources or work on a laptop and use the Apple iMac 27” or Apple 24” as a display.


  • AT-HD620 is capable of scaling any HDMI source to resolutions up to 2560x1440
  • Supports native resolutions of Apple iMac 27” (2560x1440) and Apple 24” LED
  • HDCP1.1 and DisplayPort 1.1a compliant
  • HDMI and Mini DisplayPort inputs and Mini DisplayPort Output Switch and scaler
  • Supports 50/60Hz frame rate conversion with 60Hz output, which would allows users from all over the world to use their HDMI equipment
  • Supports 3-D motion video adaptive, 3-D de-interlacing, hue, saturation, sharpness, RGB (color tone) level, and aspect ratio size
  • User has the ability to control the HD620 via supplied IR remote or Manual button selection
  • Mini DisplayPort Input is pass-through only, no scaling
  • Compact size with elegant design

Note: The Atlona HD620 will pass audio from the HDMI to iMac 27" display via Mini DisplayPort Connection; however Apple 24" LED can't take audio from Mini DisplayPort (only though USB), therefore user would have to either use a separate audio output from the HDMI device to connect to AV Receiver or can also use an analog stereo output from HD620 to connect to a set of powered speakers.
