1080ti Sierra

[clustermagnet]

Hope someone has a solution for the problem i am having.

1080ti, sierra 10.12.5 (16F73). Display port to display port cable running to a PA328Q Asus 4K monitor.

I am able to get 1080p no problem, however when setting to any higher resolution, the monitor does the pinkish color rainbow flicker and I have to roll back to 1080p.

Ive tried rotating the slots on the card itself. I know for a fact this setup runs 4k no problem (linux). Any help would be greatly appreciated guys!

Thank you!

The resolution is listed as "1080p"? I'm not sure if this make sense in this case but that sounds like the Mac thinks the monitor is a TV.

use safari technology preview and switch on experimental features (if you are trying in browser) Opera is better though.

and yes to fix your problem.. SwitchResX is best bet. http://www.madrau.com
