Windows 10 Messed Up My Display

[mikstone]

I upgraded to Windows 10 and it went smoothly. But when I booted it up, I found that my screen size was too small. I think that that my display resolution has changed but I cant change it back as the option to select display resolution is blacked out.
I have an Nvidia GTX 960M and Intel Integrated.
