how to disable 4k secendary display?

[AC Question]

I opened developer options and changed only some animations,but my brother changed something.... He said he clicked something like secondary screen and picked 4k, and now my device is weird and i can't do anything with it. Please help?

Go back to your developer options, right under the animation settings, there is the simulate secondary display option. Set it to none.
