I use my Samsung TV as a monitor on my (Alum) MacBook and I have my wallpaper switching every 1 minute. Today I took my Macbook with me, and set the wallpaper switching to every 5 seconds. When I came home I connected my monitor, opened the lid to the Macbook, turned it ON, and closed the Lid. When my computer started, it would put my Macbook (and TV) to sleep every 5 seconds after loading, and I couldn't do anything.
I finally opened the lid and went to my wallpaper settings and TWO preference panes appeared at once, one on my TV monitor and one my MacBook. One was set to 1 minute, one was set to 5 seconds.
Has anyone ever encountered this? Know of the issue / corrective measures?
Your help is really appreciated!
(PS please do not scold me about wasting resources on my wallpaper settings
