window/s screen adjustment

[jollysolivajonathan]

Recently, i have used the internet but i cannot read the information because the image and letters are so big. And at the same time when logging cannot see the login: to type the pi, password and it the same when shutting down or raspi-config messages cannot see from the left edge of the screen and bottom of the screen.

I think you need to modify config.txt

And adjust overscan_left etc
