# TeXmaker PDF viewer blurry

I am using TeXmaker on a MacBook Retina with an additional external display. The documents displayed in the PDF viewer while on the external display are very grainy/blurry and hard to read, while they are completely fine on the MacBook screen and when opening the produced PDF with another software. I didn't find anything related to this online.

• Please help people to help you by posting a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. Have you tried adding \usepackage[T1]{fontenc} to your preamble? – cfr Apr 19 '14 at 3:15
