Hi
I have a question about my mac mini late 2012 running os x mavericks on a Benq xl2420t monitor.
The monitor it self has a 120hz refresh rate but iam unable to hit that in os x. The maximum im getting is 100hz using a mini display to display port cable. I have no issues getting 120hz in windows. Any ideas anyone
thank you so much
Mac mini, OS X Mavericks (10.9)
If by "in Windows" you mean on a PC apart from your Mini (not Bootcamp), it's probably because the PC has a better display adapter (GPU). The Intel HD4000 graphics in the Mini is not exactly "top of the line".
I wonder if OS X caps out at 100hz. I called apple care and even them couldn't confirm.

You could try experimenting with SwitchResX which allows you to create additional customer resolutions and frame rates. For example it is widely used to create proper 24p settings for use with TVs. OS X itself does not do proper 24p only 50i and 60i (on TVs). There is a trial version of SwitchResX available.
This would only work if it is a software issue and not a limitation of the Mac video interface.

After doing a search the best I have seen is that it might be possible to do 720p resolution at 120Hz although in theory the HDMI version supported by the Mac mini (1.4) should support 1080p at 120Hz. It maybe that using a dual-link Thunderbolt to DVI adapter might help see http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter
It suggests DisplayPort 1.2 is needed which is supported in Haswell chipset machines which unfortunately the Mac mini does not yet use.
120hz in Os X
