As a side note, I have had a few questions on fuzzy imagery, but never got enough responses from reporters to track the issue down.

There may be several causes for this, in some cases I suspect linking to very very old versions of libgd, I am thinking to remove support for these old versions.

In your case, the problem is likely to be up-scaling after dvipng has rendered the image. What I was answering below is that I do not know how to massage org-mode into generating high-res images but display them at the same size as before.

The dvipng command-line switch for resolution is -D if that helps. Look for the call in org-mode and change the resolution. Something more will need to be changed to keep the size of the displayed item, this I cannot help you with (just now).

I honestly have no idea, I have not even looked at the org-mode code.

all my latex previews in org-mode are... fuzzy. These are generated with
*org-preview-latex-fragment* command, using *dvipng*.

Is there a setting I can change to up-res these? Maybe something in
