It may come to that!
If you have an NVidia graphiocs card, there's a 'rotate screen "X" to the right/left' option in the NVidia settings menu.
Under NVidia setting icon on taskbar, if you have it -the icon looks like a whorled eye, right click and bring up the right click menu.
There will be an option called "rotation settings" towards the bottom of the list.
Your options within that menu are 0 degrees, 90, 180, and 270 degrees.
This only works if you have an Nvidia graphic card and have NVidia drivers.
