Original Title - Screen Resolution
After updating from windows 8 to windows 8.1 my screen resolution fell from 1920 x 1080 to 1536 x 864.
All my graphic card drivers are up to date. When I go into screen resolution the screen resolution is set to 1920 x 1080 whereas in reality it is 1536 x 864 as shown by Nvidia Geforce experience.
What should I do?
