White horizontal line while booting

Hello yesterday i built my new pc: MSI Tomahawk B450 MAX AMD Ryzen 5 3600 MSI Evoke GP rx5700 16GB DDR4 G.SKill 3200 RAM

When I booted my pc i noticed white lines... I updated my bios and drivers now I always have the white line while booting sometimes on a higher or lower position, like shown in the video (second 16):

​

I tried: \- Clean uninstall with DDU and reinstall drivers \- Switched from DP to HDMI, got no white line with hdmi (booted 5times to test)

\- played WoW(BFA) and did some Furmark Tests had no issue
