Replaced my Viewsonic VG1930Wm with brand new Vx1940w..both being 19" inchers but as vx1940 is 1680x1050 res the text was smaller due to higher res ofcourse. I already had Large fonts enabled with my previous monitor Display Properties>apperance>font size...but still the fonts were smaller on the new monitor. So googled and found this..thought will be help if not to all atleast to a few ...so all those with high res monitor here is the way to calibrate ur text .

Changing Windows' Default Display Font Size

For clearer text try MS ClearType Tuner PowerToy
