MSS does not take screenshot of entire screen

I'm a beginner programmer and I was trying to write a program to capture screenshots. I am using MSS to do so. I can capture screenshots with MSS but only a portion of my screen gets captured. Please see code attached.

from mss import mss                                                     

with mss() as sct:                                                      

    for filename in sct.save(0,'test width{width} height{height}.png'): 
        print(filename)

edit: formatting errors

edit1: My native resolution is 3200 x 1800. When I changed my resolution to 1920 x 1080, the library works fine.
