Atlona (Dual Link) DVI to Mini DisplayPort Converter for Apple 27-inch LED and 27-inch iMac. Model: AT-DP400

The Atlona AT-DP400 is a DVI to Mini DisplayPort converter designed to convert signal from any Mac or PC computer with a dual link DVI output to a digital signal over a Mini DisplayPort connector. The AT-DP400 is specifically designed to work with iMac 27-inch and 27-inch LED which can support resolutions up to 2560x1600. Users can use the connected monitor as their main display or extend their desktop using it as an additional screen. The Atlona DVI to Mini-Display Port Converter is compatible with all Apple and PC Computers which have a DVI or Mini-DVI connections. The DP400 features an attached DVI cable and uses USB as power source, leaving no need for an external power supply. **Not compatible with Thunderbolt**

Important Notes:

Note1: For PS3 or Xbox users, you can use the DP400 converter without additional devices at resolutions up to 720p. Make sure to set your source to 720p prior connecting it to the DP400. Even through DP400 is able to pass-through very high resolutions, the Xbox or PS3 will only be able to view 720p because iMac 27-inch doesn't accept 1080i or 1080p, for this application we recommend the AT-HD620 (HDMI to Mini DisplayPort Scaler)

Note2: The DP400 requires Dual Link video card which support 2560x1440 in order to output 2560x1440 to a display. Please make sure you card is Dual Link.

How is our converter different from others:

  • AT-DP400 is HDCP Compliant, which means that you can play copy protected material through our converter
  • Apple 24" and Apple iMac 27" and 27" LED Compatible

  • Power Over USB, no external power supply needed
  • True pixel to pixel signal
  • Pro Mac Compatible, works with all professional applications such as Final Cut Pro
  • Our converter is only hardware based, therefore will never have any issues with new operating systems or updates.

 DataSheet

  My brand new Thunderbolt monitor doesn’t work with DP400. The connections look the same.
  Unfortunately none of our products support Thunderbolt based Displays.

  I have a 27” Apple Cinema Display, why can’t I get 2560x1440 resolution but do get 1280x720?
 

There are three different scenarios why this could happen:

  • Your graphics card doesn’t support dual-link resolutions up to 2560x1400. Make sure that your graphics card is dual link and supports dual link resolutions as Apple’s Cinema Display only supports three specific resolutions (2560x1440, 1280x720, 800x600) if your graphic card is limited to single link (maximum supported resolution 1920x1200), then second supported resolution with above mentioned resolutions becomes 1280x720.
  • Your graphics card supports dual-link resolutions up to 2560x1440 but it only outputs 1280x720. This only applies to ATI/AMD graphics cards and this issue only shows up in Windows OS where the drivers are not compatible with Apple’s 27” Cinema Display. When using the same graphics card on a Mac OS based machine, you can get up to 2560x1440 resolution.
  • Your graphics card is capable of outputting dual-link resolutions up to 2560x1440 but you’re only limited to 1280x720. If you have another display connected to the same graphics card where AT-DP400 is connected to (this can also apply to built in displays for laptops), when mirroring your displays, your graphics card will output based on lowest common denominator supported resolution; for example, if your laptops built in display supports up to 1366x768 and Apple Cinema Display supports (2560x1440,1280x720,800x600), your graphics card will choose 1280x720 as it becomes a lowest common denominator supported resolution for both monitors.
In order to have individual resolutions for each monitor, under display preferences, you can switch to extended display mode and set the resolutions for each monitors separately.

  Can the AT-DP400 work in a backwards configuration, allowing for me to view a Mini Display Port source on a DVI monitor?
  Unfortunately, the AT-DP400 was only designed to work in one direction and thus will only allow you to convert a DVI-I or DVI-D (not DVI-A) signal to a Mini Display Port connection.

  Can the AT-DP400 be used with monitors other than Apple Cinema Displays?
  The AT-DP400 can be used with a wide range of monitors as long as the display port is enabled. There is no restriction for brand; however the AT-DP400 will support a wide range of brands.
