How to enable screen cloning and switching between display modes on the LRC reception desk dual screen Dell OptiPlex 780 with WinXP

Short, non-technical answer: on the keyboards of the reception desk computers, press key combination

  1. ALT+CTRL+F10 to mirror the same image on both monitors;
  2. ALT+CTRL+F11 to return to extending the primary screen, i.e. showing something different on the second screen.
  3. if this stops working, restart the computer.

We do not use any more key combination ALT+CTRL+F10 to cycle through the different desktop configurations, which include cloning/mirroring the same image on both screens (also keep pressing the key combination, in order to get back to extending the image to the 2nd screen, for running an informational display (calendar, PowerPoint) to display on the 2nd screen after mirroring the lab assistant’s screen onto the 2nd screen when interacting with a client on the other side of the help desk counter).

Longer, technical answer: You have to configure this. But the Win XP dialogue: Display Properties / tab: Settings only allows for “extending” the desktop to the secondary screen. However, button: Advanced leads to another dialogue, with a tab: ATI Control Center, by the graphics card manufacturer.

If you also enable the advanced settings in this dialogue, you can get to the hotkey settings where, among other things, you can enter a key combination for cycling through Display Configurations, one of which being cloning.


In addition, you can save this configuration as such:


Why all these minutiae? You cannot have LRC clients and staff at the help desk communicate with the help of a computer (and all the goodies accessible now, from intranet to interwebs) if they cannot easily share the screen (and, in order to both even interact with the screen, share keyboard and mouse, which are easy to duplicate, if you have some spare USB input devices lying around). If you can make them share, you have applied AI to business problems (compare dual screen system in the LLC entrance area here). If calling the after state “AI” sounds too lofty to you, you may call the before state  “flying blind” instead: I just care about the delta which remains the same.
