This is what I was looking for, and it should be fine. So that doesn't help us.
Have you noticed if the "blurriness" is better or worse in some programs than others?
(By the way, at about this point, it'll be tempting for you to start questioning your own sanity, and wondering whether it really is blurry or not. Keep trusting your initial instinct - if you think it's blurry, it is.)
