Q: Connecting a 144hz monitor to 15'' retina macbook pro?

Hi, I recently bought the benq xl2411z 24'' monitor which has the capacity to run in 140hz as opposed to 60hz. I have been told that you cannot run 144hz in OSX but you can do it in Windows (bootcamp),


Right now the screen is connected via HDMI; however, I have been told that HDMI is incapable of running 140hz and that I need to use DVI.

 

So basically, I'm wondering what is the best way to connect the external monitor to run 144hz?

 

Thanks!

 

BTW I have a mid 2014 retina macbook pro 15'' with intel iris pro (not discrete graphics).

MacBook Pro with Retina display, OS X Yosemite (10.10.1)

    You need to use a Mini DisplayPort to Dual Link DVI converter that supports at least 120 Hz. It may work at 144 Hz. There is no other way.

    Thanks for the reply, I eventually figured it out on my own. But for anyone else looking into this, yeah you need a Mini DisplayPort to Dual Link DVI converter (the expensive one, not just the Mini Displayport to DVI). It does run 144Hz which is good. In my case I have a eGPU I was building, so in the end I didn't need the adaptor after all; but for most people you'll need the adaptor if you want to connect a high refresh rate monitor directly to your MPB.

    I actually have the same monitor for my 13" Retina MBP and was wondering what the cheapest "Mini DisplayPort to Dual Link DVI converter" would be that can run 144 hz.
