    Hi All,
    Does anyone know or has anyone tried to use a 120hz Monitor using a mini display port to display port (full size) cable. Just wondering if OSX Yosemite even supports native 120hz monitors. I only want to run at 1080p (1920x1080)

    DisplayPort definitely supports it, and I'm pretty sure Intel HD4000 supports it. Not sure about OS X, though, as I've only bothered with it on a gaming (Windows) machine.

    Worst case scenario is you'd be running the monitor at 60 Hz.

    My 144 Hz monitor automatically goes to 60 Hz when I plug in a single-link DVI connector.

    Just tested my Mini Display Port (Thunderbolt) to Display Port Cable, OSX Defaults to and SwitchResX reports 1920x1080@100hz.
    OSX Display Preference Pane does not show refresh rates - only the screen resolution.
    So even though the Samsung is an 120hz 1920x1080 display SwitchResX does not report a 120hz refresh rate as default.
    However I can up the monitor to higher resolution with SwitchResX (2560x1600@100hz) but it is not that sharp with smaller print..

    With HDMI Cable SwitchResX reports 1080p@60hz resolutions with a bunch of other 60hz options as well which is what is to be expected as HDMI (1) only supports a maximum of 1080p@60hz.

    Monitor is Samsung Syncmaster SA23950 (3D)

    So my advice to people is buy a cheap mdp to dp cable and forgo Apples expensive USB/DVI-D solution.

    Can you create a custom 1920x1080 120 Hz resolution in SwitchResX and see if you can make the monitor work in OS X at full refresh rate?

    What about 105, 110 or 115 Hz?

    HDMI should support over 60 Hz, but the monitor may be configured to only report 60 Hz as a supported refresh rate. Try creating a custom resolution in SwitchResX at a higher refresh rate and see if it works.

    I was able to run my Seiki 4K TV at 1080p 110 Hz over HDMI from 2012 15" rMBP.

    I don't know if monitors are any different than tvs when it comes to this, but a 120+hz TV will take 60 hz content and either just repeat frames ("draw" each frame twice for 120hz, 4X for a 240hz) or will interpolate the extra frames between the original frames, if there's some kind of motion blur reduction software running on the tv.

    I created a custom resolution which I think is correct (I saved then copied my EDID info for 120hz)in SwitchResX.
    Unfortunately after a reboot the custom resolution shows as invalid.
    Still 100hz is better than 60hz :)

    What's the highest refresh rate that works? Have you tried 105, 110, 115 Hz?

    I have to purchase SwitchResX to allow more than one custom resolution. It wont let me delete the 120mhz custom now from the menu.
    I am not purchasing this software (read rip off) just to test different refresh rates. Sorry.
