So I'm a desktop support technician. A user here came to me with an interesting issue. His desktop has rotated 90 degrees. Its sitting long way with a resolution of 1024x1280. Mouse controls are rotated as well. Everything is functioning normally, just rotated. I've looked at the settings in Properties and didn't see anything to change the orientation of the desktop. The problem isn't in the monitor (older Dell LCD) as it displays the monitor settings correctly and resolution as 1280x1024. The user told me he had set a binder on his keyboard and this happened. I'm sure he hit some keys in sequence that caused it, however, I have no idea what keys. Never seen this before. Any help would be greatly appreciated.
