Question No HDMI signal on my first PC build ?

[Elypsix]

Hello, so I built my first PC.
I ve managed to turn it on (fans, lights). But that’s about it.
My monitor says « No HDMI signal » and whenever I have it connected to my motherboard (without or with graphic card) or to my graphic card (when installed).
I had to update the BIOS which I think I did with an USB.
Here are the specs (if more are needed I will give them):
CPU: Ryzen 7 5800X
MB: ASUS TUF Gaming B550-Plus
PSU: AeroCool Lux550

The monitor works fine and the cable also.

even tho your mainboard has hdmi output, your CPU doesnt have integrated GPU, so that hdmi output wont give you any picture with your current CPU
the only way to get picture is from GPU video outputs

your mainboard should have four debug leds showing you POST progress, if some debug led gets lighted up and wont budge after while, then it should tell you where is your issue

or to my graphic card (when installed).

You don't get a picture either with your graphics card and display cable connected to it?

Mainboard video won't work as said, only Ryzen cpus with G (graphics) suffix has igpu.

What graphics card have you got?

None of the four leds light up.
