I have a Latitude D620 and a Viewsonic PJ256D and when both are on and projecting an image everything works fine. 

 

I have tried to open a Powerpoint document and then toggled between local and shared video and am experiencing problems.

 

It appears that the Powerpoint document jumps to 400% visibility on the application and there is a bunch of flickering when clicking to the next slide and or paging down to the next slide.  Nothin happens as I am just stuck on the current slide.

 

Any help would be great on this.  I have searched for possibly newer drivers for the Viewsonic and can not find any.  I have also looked in the forums for help regarding this issue and seem to not find anything.

 

Thank you in advance.
