The pipboy is really blurry, how do I fix it?

It is supposed to be an old CRT display, so it is a bit fuzzy and blurry. That's normal.

If it is so blurry that you can't read the text, then you have another issue. Also, you can zoom in and out of the maps to see the markers better.

Not the screen, the actual device. Screen is crystal clear, but the labels and buttons are blurry.
