My Acer TM5720 used to run on Vista. The ATI utility worked perfectly to manage multiple monitors. (I have an external display to the left of the laptop. The external should be the primary display and the laptop screen the secondary. When I remove the external display, everything moves back to the laptop display automatically. Connect the external display and it becomes the primary display again.)
Now I'm running Windows 7 and there are no official ATI drivers available. I am using the Windows display driver for my screen card (ATI Mobility Radeon X1700). Windows allows me to easily set up my display arrangement, however when I disconnect the external display, the laptop screen does not become the primary display and all windows open on the external display becomes inaccessible.
Is there any (free) software out there that can give me back the functionality I had before?
