"Blurry Text" was a wide expression. When I looked at your picture, I was shocked - that was really worth complaining about!
It is difficult to understand why it is happening, only with some. Perhaps MS, in their wisdom, have decided it has nothing to do with their OS, but is hardware related - RIP.
Anyway, glad you got the problem resolved.
P.S. Later.
I might have to retract on that. When I expanded you picture (second click) the text was as close to perfect as it gets. I am still of the opinion that it was a screen resolution problem. But this is far from explaining why only in IE !!
