Font - best one?

I found since I updated to v12 the font I was using before (Georgia, 11) looks different and now not so easy to read. I guess it has to do with the high DPI, I'm not sure what that is, but I think I need to change the font. Which font is the best one for readability? Which font is used in the images of listers n the Dopus manual? That one looks easy on the eye.

The DPI changes should only affect the size of the font, so making it larger or smaller might return it to what you were used to seeing.

The default font on Windows 7 through to Windows 10 is Segoe UI, 9.

Thanks! That's a nice font, I haven't used it before.
