How to go back to single screen from dual display?

I recently got a LG 45" ultragear monitor and figured out how to extend the displays into 2 displays. But is there a way to go back to 1 display and use the entire monitor?

When I went into my display settings and clicked "Show only on 1", the right half of my screen just turns black.

Appreciate any help I can get.

    Open the Display settings by pressing the Windows key + I, then click on "Display".

    Click on the display you want to disable (usually Display 2).

    Scroll down and select "Show only on 1" for that display.

    Important: Do not select "Show only on 1" from the drop-down in the display that is part of the large monitor. Instead, ensure only Display 1 is active.
