Going from a new MacBook Pro M1Max to a 2007 Apple Cinema Display 30″ with USB3.2 Type-C to Dual Link DVI-D HDCP OFF. It works pretty well but in areas of the screen that are supposed to be black, there frequently are light flecks of static. It’s especially noticeable in Final Cut Pro X. On my other 4K non Apple monitor (HDMI) there is no such static on the same program when I move it over to that monitor. I have tried connecting through several different USB ports including a Sonnettech Thunderbolt 4 dock. Any ideas?
