Problem
You have noticed that your screen is more zoomed in/out than normal when you are on a web browser.
Solution
It could be that you have changed the zoom settings in the top corner of your screen. In this case, go to the three dots at the top of your screen and change your zoom percent.
Alternatively, it might be that you have accidently held down the Ctrl button and moved your scroll wheel so the screen may have zoomed in or out. In this case, just hold the Ctrl button again and move the scroll wheel up and down until you are happy with how the screen looks.
