Hi,
I deal with very similar issues. I have Samsung S24C650PL 1080p (connected with HDMI), which I bought one year ago. I used it a lot with Windows without any issues. Last week I bought my first Macbook Pro Retina and since than it is a pain.
- All fonts are significantly more blurred than with Windows.
- Especially scanned PDFs are horrible, very difficult to read, much worse than the rest of the system.
What is, however, really weird, if I move the Preview app with the PDF from the internal display to the external, it shows the right and sharp image for cca one second before it becomes blurred. So it is obviously software-related issue.
I tried:
- Deactivate "Use LCD font smoothing when available" --> no effect at all
- Deactivate "Smooth text and line art" --> no effect
- Use any possible settings in "Displays" --> no effect
- Call the Apple support and talk with them for 40+ minutes --> no effect and no help
What is even more weird, if I use Parallels with Windows, it is okay! Even in the small window and not in fullscreen, the Windows show everything just as they should - crisp and sharp lines and fonts.
The unique "workaround" I found is related to PDFs and their readability.
- Install Acrobat Adobe, which uses obviously a different rendering engine than Preview app. (However, I don`t like the app.)
- Install Foxit Reader for Windows under Wine (even that is much better than Preview app.)
I am pretty frustrated with these issues, because I thought Apple cares a little bit, but it is simply not true.
And I can`t understand why MacBook Pro Retina can`t render the fonts at least so well as a cheap notebook for 200+ euros. 😟
