Zerodha web not support wide screen monitor why? How to fix this
As Zerodha Kite isn’t long blocks of text,
the justification to have whitespace on the sides like Wikipedia
is a non-sequitur. 
(already clarified the same on that topic-thread)
Extending the chart area and removing large empty white space on the sides,
enables a higher resolution chart / longer duration to be viewed on-screen with the marketwatch on the side.
Hopefully, the devs see sense and enable this. 
But, don’t hold your breath waiting for this.
