Just wonder, how does the font rendering look like on the Microsoft's Surface Pro?
FWIW in my case, the problem has never been on the Tablet side, only on the attached monitor side.
Have you tried using a Zoom or scaling change to help change the symptom? FWIW I am still using 112% in my IE tabs. And I think I am using some of the Change only the text size options in the Display dialog but don't know how to find out for sure.
Related to this, does anyone know why MS stopped allowing us to use Intel's HD Graphics tool? I keep imagining that there are useful tweaks in it but now can not test that recollection.
