PowerPoint Projection Problems
So the temperature could be affecting the projection onto the LCD?

Again, not an expert, but I would suspect that the projector is just like a display unit. It has the 'picture' data from the computer, plus a signal to make sure that the picture is displayed correctly, i.e. synchronised. It might be that the signal is weakened or distorted as the computer gets hot. It is not necessarily the same signal as the one that controls the laptop display. I would try a different computer, if one is available. Even a standard PC would do for a trial. Brian.

You can plug a projector into the video port on a regular desktop or plug a regular monitor into the external video port on a laptop. Both are monitors for all practical purposes. It is not necessarily the same signal as the one that controls the laptop display. On the money again. Some laptops send the same signal to the LCD and the external video but most newer ones have true dual monitor support ... a separate signal for each, internal and external. I would try a different computer, if one is available. Even a standard PC would do for a trial. Brian.

I tend to think you all are absolutely correct and that it has to do with the
temperature. I also tend to think that the docking station has a fan in it (or bigger one) and the small thin laptop away from the docking station with no frills, no cd drive, not whole lot of anything does not have the capacity to handle a full training day of 8 or 9 hours like my heavy bigger older Sony Vaio. I have a new 13 inch Lenovo Thinkpad and again, when you take away the docking station, you have a very light thin lap top but not much of anything else. I think I will try it with the docking station at my next training and see what happens. I do really appreciate all of your advice in helping me figure it out. -- Shayn "Steve Rindsberg" wrote: In article , Shayn wrote: So the temperature could be affecting the projection onto the LCD?

Please do let us know how this works out. Oh, add also the specifics on the Thinkpad model you're using ... sounds like the same one as mine. I'd like to know if I'm in for trouble over long sessions. ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ |
