I have a RX5700XT and i can't install the AMD driver on my computer.
When I install it the process goes to 67% and after I have a black screen. when it happens my screen display a breaking monitor green during one second and after black screen. If I move my DP to another it works one second and after I have the same result.
To connect my computer to my screen I use Display port 1.4.
In HDMI it doesn't work too.
My config :
Motherboard : ASUS ROG x570 GAMING-F
CPU : Ryzen 3800X
GPU : Asus STRIX RX5700XT
RAM : CORSAIR 16 Go
Display : LDLC RS232
Thanks for your help.
