Hi,

I have a Ryzen 5 3400G, MSI B450M gaming plus max and two screens with connection VGA, I bought two adaptators, HDMI to VGA and DVI-D to VGA, when I connect the screen with adaptor DVI-D to VGA, the screen have interferences, like lost signal in TV, 3 seconds working well, 3 seconds working bad, I taste the adaptor DVI-D to VGA in another PC with another GPU and works well, Any idea where is the problem?, motherboard, apu or software? . I have a clean installation of windows 10 1909 with the last drivers and firmware. Thanks.
