Salamu alaikum , just turn on your laptop let it on for one minute then plug the screen cable from back or side then the screen will.turn on if not check the source in the screen try to change source till you get signal .

What do you mean screen cable?

HDMI CABLE

I tried that and it said there was no signal

CHANGE THE SOURCE ON THE SCREEN THERE ARE A BUTTON CHANGE THE SOURCE OF THE SCREEN DIGITAL OR ANALOGIC SO TRY PUSHING THAT BUTTON IT MAYBE CHANGED AND IT WILL WORK MOSTLY THATS THE PROBLEM

I tried it on my TV and made sure the source said pc and when I did that the tv was black and the computer screen did not pop up

I dodon'know about that its a new cable I've used for awhile with no problems until I downgraded to windows 10 Fter the installation was done for windows 10 I couldn't do anything. Cause it's black

maybe there are only one solution is to unplug the screen of your laptop from motherboard and plug the screen of HDMI thats gonna work 900 %  bcs its detecting your laptop screen as first screen .
