There's also a program that Windows has that magnifies whatever the "magnifing cursor" is over. It's like a small window on your computer screen that shows you an enlarged version.
So, if you need to see something larger for one thing... you can use that program.
(It's under "Accessibility".)
Magnification and programs like Zoomtext are very helpful for a lot of low vision and legally blind people.
Unfortunately I'm too blind for magnification. I use a screen reader.
