ghost images

[conomark]

In my presentation, a welcome screen proceeds the beginning of the show -
possibly up to 45 minutes. When I move to the next slide, the title text of
the previous slide is faintly visible. Is this a powerpoint or projector
problem and are there any suggestions to alleviate this problem?

The presentation is used during a church service, and the title screen is
displayed before the service starts, and part way through the service before
the presentation actually continues.

I've heard of burnt-in images in (old) monitors. But I did not know, it
existed with projectors. But in any case I would think it's a hardware
problem.

You could have a welcome loop instead of a welcome slide: Make a small
presentation of 2 (or more) slides and set them to advance automatically
after a few seconds. Place a 99% transparent rectangle on one slide and
assign a hyperlink to your main presentation to it. Copy this rectangle to
all of the slides of this welcome presentation. The movement should avoid
saving ghost images.

When you're ready to start your main presentation, just click anywhere on
one of the slides to change the presentation.

Best regards,
Ute

Thanks for the great tips. One little problem I'm still having though. First a little more info: Infocus LP640 projector connected to a laptop. The laptop is not accessible to me during the presentation. I use the remote that came with the projector to advance slides. This works with your method of using the hyperlink to the main show with one little cosmetic problem. While the pointer is on the hyperlink, a little yellow box is visible with the path of the hyperlink. Since i don't have control to move the arrow - just "key press" with the remote, I can't seem to make the yellow box disappear. Any suggestions.

If the 'title text' you refer to is the Welcome screen, then it is a
projector issue. The image is in place far too long and is being 'burnt'
permanently into the LCD or polariser screens in the projector. Not
recommended if you want the projector to have any real useful life, quite
apart from the lamp being quietly consumed!

Once done, it cannot be undone, apart from replacement components
(expensive) or a new projector (probably not so expensive).

After the show, the projector is powered down by manufactures suggested way.
The next time i use the projector, there are no "ghost images". They only
appear after the title screen is visible for an extended period of time.

I understand, but the problem is still with the projector being used to
project a fixed image for a long period and will give you more grief later
on.

Perhaps you could animate the 'Welcome' text and repeat it so as to avoid
the long exposure time.

I have incorporated a welcome loop with a hyperlink to the main show. This
alleviates the "ghost imaging" and hopefully any damage to the projector.
This process brings on a new problem. I don't have easy accessibility to the
laptop during the show. I use the remote that came with the projector
(InFocus LP640) which doesn't have a "mouse click" button - only and advance
to next slide button so I can't "click" on the hyperlink to go to the main
show. I realize that the only solution to this problem is to make the
laptop more accessible during the presentation, but if you can think of any
other solutions where i can use the remote, it would be greatly appreciated,
Thanks

One possibility: get a remote for the PC, one that supports mouseclicks,
instead of using the one from the projector.

Another: a mouse at the end of an extension cable.

I didn't even know such a contraption existed - Remote for a PC. Sorry for being so amateur about this. I'm going to be looking into a remote/wireless presenter with mouse capabilities. Thanks a million!
