Hi,

I'm currently on Mac OS 10.12.6 with a NVIDIA GeForce GTX 1070 8191 MB plugged on a 4K screen via a DisplayPort cable

I'm facing some Black Flashs while working on my Mac since I've built it sadly. More often on softwares using some ressources (Adobe Photoshop / Premiere Pro) but sometimes with the Finder and Chrome opened only.

Any ideas on why I'm facing those issues?

Here's attached to this post my Clover config file, Verbose mode video and BIOS screen grabs

Note that web drivers are up to date as well maybe not the GPU itself though..)

Thanks in advance and son’t hesitate to ask more details if it’s needed!

Regards,
Charles.
