LyX ⇒ I can't visualize DVI and get PDF to decent resolution

[Robpazzuzu]

Good morning to everyone,
I'm new to this forum and i need support to complete my bachelor of science thesis with Lyx,infact every time i export my lyx file to pdflatex and i open it, it appears to be with a too low resolution, with body types scoloured. Usually body types have to be black, not grey. Can you help me? I've the last lyx version. Also i can't open dvi file that i export from my lyx file (the dvi exportation process produces also a lot of postcript file in the same folder).
Thanks in advance
update : maybe the solution is to convert to dvipdfm format, but i get error when i try, see the image

Welcome to the forum!

I think the font in your document is bad. Please try this: add the line

\usepackage{lmodern}

to your document preamble (via menu, Document settings).
