Why do lines look blurry with linewidth 1 in R2017a?

I am using R2017a and when I plot lines with linewidth of 1, they appear blurry or pixelated, as in the screenshot below. How can I fix this so the lines look crisp? I suspect it is not Matlab but rather some operating system setting (Windows 10), but any help would be appreciated.

You might have to switch to 'opengl' hardware mode for graphics smoothing functionality. To do so, you can run the following code in MATLAB command window:

opengl hardware

Further, you can use the following settings to turn on line smoothing (if disabled earlier) in MATLAB:

set(0,'DefaultLineLineSmoothing','on');
set(0,'DefaultPatchLineSmoothing','on');
opengl('OpenGLLineSmoothingBug',1);

These tips worked, thanks.

Line smoothing was deprecated in 2014b, so I suspect that the only one that really changes anything is the first suggestion.

I think that the reason that you are seeing this change is that MathWorks found some issues or instabilities with your graphics hardware/driver combination and felt it was better to emulate graphics on software, which doesn't support anti-aliasing. You might want to try updating your graphics driver, if possible as this usually also solves the problem.
