Screen flickering. Windows 10 and 2 monitors.

Hello folks, how you all doing?

I've always used a multiple-monitor setup and flux worked just fine but now things got bad. I've upgraded to windows 10 and got a new monitor.
Now every time I turn Flux on, the bigger screen connected via HDMI-DVI adapter-PC starts flickering badly. The other small screen, connected straight through HDMI is fine.

I notice when I turn on MOVIE MODE it reduces the issue quite a bit. But not 100%.

So would this be because of Windows 10 or Flux is not compatible with all monitors, which would explain this happening in my new display?

Hope you can help me out.
Thanks!

Okay now I set light at night to 3700 and it seems to have stopped the flickering a bit, definitely LESS than with 3400.

Weird. Anyone?
