At work, I'm using a Fujitsu Lifebook E series laptop, along with a HP ZR22w secondary screen, connected on DisplayPort. My OS is Windows XP, fully updated, but without Admin privileges
As soon as the screens shut themselves down (power off, or automatic sleep mode after idling too long), the Windows configuration for my screens (extended desktop, and relative positions of the screens) disappear. But when I go to Windows display settings, they seem unchanged. I have to mess them up and redo them right to retrive my previous configuration. This also happens when I shut down manually the secondary screen (using power off button).
Given that I have no admin privileges, it is not possible to use a software like UltraMon. I used a similar configuration at home for several months, and I never had any problem like that.
Any idea how to fix that?
