I am using a Sony Vaio laptop with windows 8 pro. as the system has better configuration i added a second monitor to extend display that can be very helpful for me in my work. Everything went fine for a day but now the wallpaper disappears from the second monitor in every 2 to 3 minutes, I need to set it again, it remains there for same duration and disappears again. Few times, only few times refreshing the desktop brings the wallpaper back but again it gets disappear.
Any idea what is wrong and how can i fix it permanently?
