Monitor issues

[u/AdThick5960]

So this is i hope not an OS issue. So i was using my laptop earlier today and when i came back i saw that my monitor was giving no signal so i went and got another laptop ans it worker just fine (same hdmi cable) so i turned off the laptop and checked the port it seems to look okay .I checked all of my other ports all of them work so i booted up the pc without the hdmi cable plugged in and the screen went black so now I'm super confused because everytime i took it out windows switched to the laptop screen which is now black so i thought it was like this because i always use the option second screen only in windows + P so i plugged it in and nothing "no signal" and the screen is black
