The bigest problem with laptops is they are usually set-up with shared memory for Video, meaning they get a chunk of the main memory, but that can be made smaller by system requirements if needed. So you really don't know how much is actually dedicated to video.
Instead of double clicking the display to move it to the second monitor, try dragging it and resize it to almost full screen size but not quite. This may make a difference in the sync. Some have found this worked.
