Touch LCD with Mac Mini I bought my first Mac Mini today. I'm using touch screen LCD PL2735M (http://www.iiyama.com/gb_en/products/prolite-t2735msc-2/). When I click on screen, mouse is moved to that place, but no click is issued. Is there any touch settings? (sensitivity, calibration). Thank you.
This might help...  when using a trackpad on a MacBook, tapping does not, by default, click the mouse...   there is a setting (System Preferences -> Trackpad -> Tap to click) that must be enabled.   

You might try checking for that...  or something similar, to enable "tap to click" for the monitor (if possible).   I can't say 100% this will work, as I've never seen a touch screen used with a Mac... however hopefully this helps.
