Is there an easy way to zoom into a specific part of my screen and lock the position? I’ve tried using Windows Magnifier but it moves around with the mouse, and with the mouse setting turned off it’s difficult to position.
I would suggest you could use Magnifier with Lens (Ctrl+Alt+L) view. And you can change the size of the lens using the sliders in the menu as the following screenshot.
You’ve got three different options for the type of zoom you can use on your screen.
Docked gives you a half and half view, so one side of your screen is normal, and the other half is zoomed in.
Full screen brings up the zoom across your whole monitor.
Lens (which in our opinion is the most useful for most scenarios) is a smaller box of magnification which follows your mouse around the screen, whilst the rest of the screen stays at normal magnification.
