I had a serious issue after updating my blog to the Word Press 2012 Theme. The font looked like CRAP on my home PC and my Work Laptop. Doing a little bit of research on the new Open Sans Font I learned I needed to go to:
Control Panel > Display > Adjust Clear Type Settings
Once I turned on Clear Type and calibrated it, Open Sans stopped looking like a steaming pile of Lego poo and started looking pretty good. The side effect is I think the rest of my fonts got a little fuzzier, but I’ve been at work a long time so maybe coming back tomorrow will help me out with that.
If you read my blog and notice the letters i and l and t look all blocky and crappy and thicker than other letters then give the Clear Type settings a try.
