GTX 680 4 Monitors Graphics Problems Sierra

[gatd]

I have a mac flashed GTX680 I need to run 4 monitors, never had any problem in doing so in el capitan I just reinstalled the earlier nvidia drivers from yosemite all working good.
Today I installed Sierra only three monitors working then reinstalled the early nvidia drivers and got all 4 monitors working again.
There seems to be a problem now with the graphics slow and flickering jumpy with slight tearing when I go on the dock siri etc.
any help please?

May be you can try to post in the Mac Pro forum. Due to lack of upgrade from Apple, lots of membera at there still discussing the old stuff like the GTX680.

Also, quite a few guys at there running multiple monitors. May be you can get better / sooner reply from there.
