    External screen used to work, now just goes to sleep

    I have windows 10, always worked great with external screens. Without a reason, the external screen goes to sleep between 10-60 seconds after plugging it into my laptop. The display setting shows the screen is connected and working fine (see screenshots), but the screen remains in sleep/ dark screen mode.

    I've checked the sleep settings, put all display settings back to regular, restarted, uninstalled/ reinstalled/ updated NVIDIA, removed desktop background images. All together I've spent around 3 hours researching and trying forum solutions from the past 10 years and nothing is working.

    This screen works fine when plugged into another windows 10 laptop so I'm fairly certain this has to do with my laptop.

    Any help on this?

    No it doesnt actually. Another screen works in that port, I can have 3 screens.
    I still have to swap the cord to see if that't it. Although it IS a samsung screen which doesn't surprise me.
    I will post solution
