Screen Flickering on 4k Monitor

[dyhardman]

I recently installed mac os sierra on my computer, and I am currently experiencing a lot of screen flickering. I am currently using integrated hd 630 graphics, although this should be sufficient to run 4k, as i can achieve this in Windows 10. Wondering if there was any fix for this, I am running on a Gigabyte GA-H270M-DS3H with a Core i7 7700, 16gb ram, and a 128gb SSD.

Experiencing the same problem, Kaby Lake 7700K with HD630 on 4K monitor, and screen blacks out every now and then. it got better when setting IntelGFX parameter to 0x59128086 and ig-platform-id to 0x59120000, but not the blackouts are not completely gone. Help appreciated.
