HI ! I am using Windows 10 and Mathematica Home Edition 10.4.0 on a PC. In Windows Control Panel I have adjusted my computer resolution to 1680*1050. And it all works fine - except when I start Mathematica ! In Mathematica the screen resolution is only 1344*840 and my computer works only with DirectX 9. As soon as I exit Mathematica, the computer works with a resolution of 1680*1050 for all other programmes, and with DirectX 11.2. How can this be ?
