Question RTX 3060: monitor not recognized (new build, no OS installed)

Hi!

I just completed a new pc build (my first) but it seems my monitor is not recognized by the GPU...

Everything seems fine (CPU, RAM, power supply) and the GPU has power (it is lit) and is recognized by the motherboard because the debug led on it isn't lit.
There is still no OS on the machine and I could neither install Windows, update the BIOS nor the drivers of my GPU because if the pc seems to run fine, when I connect a monitor via the HDMI of my GPU, the monitor says "No signal". And I cannot do anything in the BIOS without a screen... (and my CPU has no integrated graphics).
The monitor works just fine with another pc, and the HDMI cable is also fine. I checked an re-checked that the GPU is in its slot.

So either I did something wrong, or maybe the GPU cannot connect to a monitor via HDMI without having updated drivers ? I'm lost so if someone has an idea of what's going on, I'll glad to hear the solution.

Here are the parts of my PC:
GPU: Msi Geforce RTX 3060 Gaming X
Motherboard: Msi Mag X570S Tomawhawk max wifi
CPU: Ryzen 9 5900x
RAM: 2x16Go Crucial Max DDR4-4400 CL19
Monitor; Samsung LE22B450C8W (a tv)
(And the others: Corsair RM850X, 1 HDD & 1 SD M.2)

Are you sure you plugged the HDMI into a GPU port and not into the motherboard?

I did the same thing when I built my first computer. The easiest solutions are often the ones overlooked.

Yeah I'm sure of it !
I tried both HDMI ports (first the GPU and after on the motherboard to be sure)

Thanks everyone. This morning everything was fine so maybe the PC just needed a good night sleep... Don't know what the problem was but happy it disappeared !

(Before that, I've re-flash the BIOS, take out the GPU and put it again in its slot, that's all)
