I’m using CAC-1510 to connect 2018 Mac Mini to Dell 3007WFP at 2560×1600. I’m glad I found this adaptor, but I’m getting random scattered red or green dots appearing and disappearing across the screen quite frequently. Sometimes appears to follow a pattern, either dark areas of the screen, or in a band across the screen. Don’t have this problem when connecting the same display directly to my windows PC using the same DVI cable.
