I upgraded my MSI Wind Top 2400 to Windows 10. The Standard Graphics Driver from MS failed. With the AMD-Driver "non-whql-64bit-nieg-radeon-crimson-16.2.1-win10-win8.1-win7-feb27" works it. But the picture is not exactly sharp. All letters and Icons are not claer in it apperance. The Solution is 1920 x1080 with a Frequency of 29 Herz. What can be the Problem?
