I recently dropped my keyboard and when I grabbed it to keep from falling on the floor, I must have hit a combination of keys that turned my monitor "sideways" in other words, I cannot get it back to "normal" it is reading left to right instead of top to bottom. When I go into my control panel, it will not let me select the correct monitor for viewing. I cannot keep turning my head all the way to the right to view my desktop correctly. Any suggestions?
