Hi all, I got a new monitor (Acer x233Hbid) that advertises itself as 1920x1080 with a max refresh rate of 75hz. When connected to the Mini (new 2009) I get 1920x1080 ok, however I only get a 60hz refresh rate. Is there something about the Mini or is it the monitor that limits this to 60hz? Would I notice any difference between 60hz and 75hz anyway? Since 60hz is unchangeable in System Preferences, I have a feeling that's the preferred setting for LCD monitors.
