This is Lisa (Chris is back at school)- I have an HP compaq nc6000 with
Intel Centrino. Yesterday we tried to turn down the graphics acceleration
following the instructions. The problem is that we were not given that option
by my system. Vista is a little different and I don't know if that has
anything to do with it, but when we got to the right place, the option to
adjust the acceleration was grayed out. We in essence came to a blank wall
and didn't know what to do next. ???
Chris et al..........
I have experimented with this on the three prominent mobile chipsets. The
Intel was actually the easiest one to work with.....go figure. Anyway.....I
have been able to get video on both screens on each chipset by turning down
the hardware acceleration. I know it's counter-intuitive but it works.
Please try it. I used to do the primary swap but don't need to any longer
unless I'm running one of my addins that needs it. Instructions are in the
link in my first post.
This is Chris trying to help Lisa.
First of all, thank you Austin for your information.
The trouble I'm having is switching the primary and secondary display.
Please read the response to Brian Lynn for the graphics system information.
Since her presentation is tomorrow, I am going to add in a hyperlink as a
temporary solution if the video will not work.
Please let me know if you have anymore input.

Lets see if I can help.
First off, if you move the presentation and videos to another machine, move
them to a folder with a short path. (Example: C:\Mystuff) Do NOT place
them on the desk top as this may have a very long path!
PowerPoint plays all videos as an "overlay". What that means in friendly
terms is that the video card displays PowerPoint on the screen as expected,
and then plays the video on top of that by using memory set aside for it on
the video card. (Hence the term overlay)
The vast majority of video cards support overlays on one screen or the
other, but not both at the same time. (There are a few that aren't limited
like this but they tend to be high end cards.)
You can usually get around this limitation by swapping out the primary and
secondary monitor and then telling PPT to play one the one desired.

I do a lot of speaking and have just started adding movie clips to my
presentations. I have been editing the video clips with windows movie
Now I've had this problem both with XP/Office 2003 and Vista/Office 2007.
The clip plays just fine on my computer during the presentation, but on
projected screen there is just a black box. The rest of the presentation
fine. This has happened at different conferences with different
I've wondered if it had anything to do with how I saved the video clip
are so many choices and I don't really know what I'm doing). Tech support
the conferences have been stymied, and my colleagues have not had this
problem. One colleague says there may be a setting "buried deep the
computer" that allows the movie to project in both places at once. ??? I
help-- I'm leaving tomorrow for another conference and need to solve this
