Q: Upside down desktop display

However, this is happening with three different laptops and three different LCD projectors as well... It happened in three different classrooms today. none of these LCD projectors have bluetooth or networking...

I did go to System Preferences on all three Mac laptops and check mirroring and Expose to see if I could flip the screen...but I did not see this as a choice.

I do not see an option in System Prefrences to flip display screen...I did select fn/alt/F7 to flip the display screen, however it only displayed a screen with different background and no dock or top of the screen displays such as Finder/File/Edit/View ect...I have also gone through the menu on the LCD projector, but it settings are all correct... it must be the MacBook Laptop...I would apprectiate ANY suggestions.

I thought maybe a visual might be helpful to my LCD/Laptop issue

Please see attachment.

(No I did not flip the image of the LCD's display from the Mac Laptop.... If our students were in a yoga class this display would be helpful)
