I purchased a MSI RX 6650 XT. I am using a Qnix2720LED with only DVD-D input, and an Acer S231HL with D-sub, DVI-D, and HDMI inputs. The Acer works just fine, but the Qnix will only display rotating primary colors. My first attempt was using a HDMI-to-DVI-D adapter, then I purchased a DP-to-DVI-D cable. But neither one worked. To check I used both methods on the Acer and it worked just fine. I also know the Qnix is fine because it worked with both of my previous video cards (R290 and HD 6370).
