Hi,
I tried many settings without success until i decided to change my Nvidia Color depth setting.
You can find it in Display, Change Resolution, i have refresh rate at 60Hz and the color depth has been changed from 32bit to 16bit.
In SereneScreen setting, i have checked the "Wait for vertical sync" and set the Display mode on "Automatic".
I have 3 screens, and it's working fine now on all 3 monitors !!!


I hope that helps.
