Does the Mini DisplayPort to Dual-Link DVI Adapter support an operating frequency of 120hz ?

I would like to use my MacBook Pro with a 120 Hz monitor (24'') and the classical Mini DisplayPort to DVI don't allow me to get this frequency.

    Short answer, yes! Make sure that the adapter is a powered adapter (via AC adapter or USB connection). This extra power is required in order to properly amplify the video signal at 120Hz. Another advantage of this adapter is that it also allows for playing games in 3D @ 60Hz (in actuality it is sending two 60Hz video signals simultaneouslly in order for the 3D effect to take place). The main thing to remember is that in order to be able to use either the 120Hz 2D signal or 60Hz 3D signal is that the monitor itself has to be able to support those refresh rates. My understanding is that none of the Apple iMacs or stand alone monitors support the 120Hz refresh rate for digital type signals (DVI, Displayport, etc). And no, HDMI 1.4a only supports 60Hz 2D and 24Hz 3D, but does NOT support 120Hz 2D or 60Hz 3D. I own an Alienware M18X laptop that is equipped with a mini-displayport and used a Live mini-displayport to Dual-Link DVI adapter to output a 120Hz signal to my Alienware AW2310 120Hz 3D monitor and it worked perfectly! I was able to play games @ 120Hz in 2D and @ 60Hz in 3D mode. I hope this information that I have provided helps you with your efforts.

  • I bought this cable to use my MacBook Pro (2010) with the NVIDIA 3D Vision and a 120Hz 3D-Ready monitor (AW2310), under Windows using bootcamp. Using the standard mini displayport to DVI, it was not able to achieve this (only let me do 60Hz), but was successful with the dual-link adapter. When booted into OS X however, in Display settings under System Preferences, I was not able to select 120Hz, only 60Hz. Hope this helps you out.

  • Like the above poster I bought the dual-link adapter and was not able to get 120hz through OSX.

  • The hardware itself does. I use bootcamp to play 3D content and games on my Windows partition using the adapter and an Nvidia Nvision Asus monitor. It works great. I haven't been able to get 3D on the OSX side though. Not sure how to do that.
