why don't my pdf's display clearly?

Let’s see an example of one uploaded through the media player.

This is a public test blog, as the active blog is private.

But, take a look at the file called
LL_Greek black-figure amphora

Thank you!!!

Remember WordPress.com’s forums are here: https://en.support.wordpress.com

yes, i looked there first. haven’t found anything.

i’ve got tons of jpgs and streaming video on our museum blog, but this stymies me. never have had an issue before.

And the pdf is large, too so shouldn’t it display well?

Is your site on WordPress.com?

Yes, https://famsfdocentce2014.wordpress.com/

Oh dear, am I confused about where to find help for .org vs. .com?

are you sure its not just a display issue?
if you zoom in, does it still appear grainy?
