Question New build display no signal to the screen

[Shyriate_Fr]

My new build seems to work "normaly" because the motherboard has debugs light that turn on when something is wrong and when I start the pc all the debug lights go off. But it is not displaying anything to the screen. I have tried every ports from the motherboard as well as the ports from the GPU.

Doing some research I think that the gpu needs the drivers to be able to display to my monitor (because it is too new/framerate problem/resolution problem) and the thing is that I don't have other monitors around.

And since i'm not able to display anything i can't go to the bios to change display settings neither i can install windows and the gpu drivers... and the it's an AMD CPU so it can't display anything on its one...

Do you have any idea how I could check my hypothesis/solve my problem.

Thank for having a look onto my question.

Welcome to the forum lets try from the begging what is in the system
even without drivers you would still get screen in the bios with AMD/NVIDIA

Try a different cable, my HDMI ports stoped working recently, have figured out why yet, but using old vga cable in monitor worked where HDMI didnt!
