So you are wanting the 10 different answers?
There is no requirement to run the slides, run the slides continuously, or not run the slides. I couldn't imagine having this TV sitting in front of me, looking at the clock, and waiting for 100 hours of slides to tick by so that I can watch a show.
If you have the time and desire to run the slides then feel free to do so. If you never came to this forum you would have never known about them and would be enjoying your TV. Nothing in the owner's manual says to run them.
If you do go ahead and use the TV, then at least don't use Vivid mode.
