Hi ! I am using Mathematica 10 on a computer running Windows 8.1 Pro. The screen resolution is the recommended: 1680 * 1050. This means, that everything on the computerscreen looks very good - except Mathematica 10 ! When I start Mathematica 10, it starts in very low screen resolution - even lower, than when I used Windows 7 on the same computer. It looks very bad ! I have tried to install ( I think) any possible driver ( 66 ! ) - nothing helps ! HELP !
