I have my video card settings to turn off the monitor after 5 mins of inactivity. This means the screen blanks 5 mins into a slideshow. It's a bit of a pain to set the video properties to "never" everytime I run a slideshow, so a feature to do this automatically (and restore the originial setting when the slideshow has finished) would be very useful.

My TV card software does it, so it should be possible!

Thanks!!
