Monitor looses signal after first reboot during win 11 installation

Hi. I plugged this pc and formatted disk in uefi.

13900K stock

2x16 GB DDR5 GSKILL 6800

Rtx 4090 Gigabyte Gaming

Aorus Elite Z790 AX

SSD KINGSTON 2TB

Seasonic 1300W PX ATX 3.0 PCIE 5.

So during installation windows 11, when pc rebooted first time,pc loosed signal and nothing happened on screen. Then i pressed reset button and it was fine and no issues again. But why that happened? Should i worry?

My monitor is Alienware AW2723DF 1440P

I wouldn't worry if it doesn't happen again - probably just a driver installation timing-out.

But it happened after first reboot during installation. Just before AORUS logo post.

@sew333: Microsoft Windows bug. Sometimes Windows doesn't pick up a signal from a connected Display Port/HDMI to a Monitor/TV. You could try turning off and on your monitor or unplugging and reconnecting your Display Port/HDMI. If that doesn't work rebooting your PC usually fixes it.

@locus-solus: oki thank you

That's normal but I did find something interesting. I had an AOC monitor I've had for over 5 years. However sometimes the HDMI signal would go black on my AMD cards. I tried two different cards so it was definitely the monitor.

In this case a monitor replacement did the trick along with replacing the cable. I have a Xiaomi budget monitor and it works much better because I never get a black screen.
