got the app in a discount and wasn't too sure how useful it might be to me. I am still so happy to have recently installed several screens and had never seen this as distraction. Then with the App: the effect is stunning, simple - just sweet. Can't say it differently. Not a must have of course but really nice. Plus I noticed you can disable the dimming for each screen separately. the only complaint, if any, would be: the dimming intensity is always global and can't be regulated separately. Which would be good in case some of the monitors are just differently bright by design or so. Altogether, however, a positive surprise!
