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 used Deltacast EDID Editor as mentioned in this post including checksum details. Link to comment Share on other sites More sharing options...
