How do i restore my native screen resolution or screen quality (1080*1920)?

I recently just did a factory reset on my android due to some issues, but unfortunately after i rebooted the phone my screen resolution had downgraded and changed from it's original. I so confused cause i'm no tech genius.

PLEASE HELP!
