Question External monitor connected to laptop via HDMI says "No Signal" ?

[MindKenn]

Hello, my laptop screen has been broken for a few months so I tried connecting an external monitor to laptop's HDMI port but monitor says "no signal". Any help with this is appreciated.
My laptop is an ASUS TUF FX505G

I have this issue right now and this is exactly what I did. I was updating NVIDIA driver and now I have a dead laptop screen and 'no signal' with external monitor via HDMI. I don't know what to do...
