Dual monitors functioning improperly
Posted on 2004-04-07
Using PowerPoint 2002 Office XP and Windows XP with a Dell 8100 laptop. Since I cannot get an external monitor to work properly I presume the problem is with Windows, not PowerPoint
Formally, when I connected a monitor or projector the desktop ran simultaneous on both monitors. Without any change in settings or installations the 2nd monitor view disappeared leaving a dark screen. I adjusted the settings and can extent the PowerPoint desktop onto the 2nd monitor but it is a blank blue screen to which I can reposition the mouse.
I restored Windows to a previous date and the problem was cured temporally but shortly thereafter it recurred and I now have a dark 2nd monitor unless I click the extend box (on the # 2 in display Properties which is the default monitor, not the ViewSonic.
3 monitors are enabled in device manager:
a. default monitor which is the laptop Radeon 7500 [disabling it had no effect]
b. laptop flat panel, the Radeon 7500 i.e. it is there twice.
c. external 2nd monitor, a ViewSonic
In display properties:
1 the flat panel on Radeon 7500
2 default monitor on Radeon 7500 also with extend desktop visable, which can be checked or not.
The ViewSonic external monitor is not there. Why?
Is the problem with 3 monitors? Before trying to set up "presenters view" in PowerPoint, which is my goal, I need to get the desktop to be seen on the 2nd monitor as it use to be.
I will appreciate advice.
