When a PDF is used in the Hype doc via resources its not blurry, but when previewing it or exporting it is.
I have the same settings, drag the pdf on stage and preview it. Let me know if its blurry/low res.
I was thinking it's supposed to be unchecked, but it doesn't seem to have an effect. I just tested it with a PDF of an image. The exported version seemed identical to the preview version.
You're saying it looks good on the scene, but blurry in the browser. Are you using any filters elsewhere in the project?
that did the trick.
