wegosi Posted June 2, 2020 Share Posted June 2, 2020 Hello @RehabMan I have the same problem. But this topic was created in 2015. There are other approaches to fix 'gradient banding' for external monitor? I inserted my EFI folder: https://drive.google.com/file/d/11Zly2e4lKKcB3SEe6aIQXoWSDe0hmN-x/view?usp=sharing Link to comment https://www.insanelymac.com/forum/topic/305679-intel-hd4600-bandinggradient16-bit-colors-issue-y510p/page/6/#findComment-2724701 Share on other sites More sharing options...

I used Deltacast EDID Editor as mentioned in this post including checksum details.
