    I have a bunch of ICONS on my desktop, just recently when I plug external monitor in, they no longer how up on external monitor, however if I open up MBP they show on both monitors. I have a Dell 2407 external monitor. Also every so often I get a lot of squiggle lines showing up on my external monitor.

    what is your question? do you want to know how to make your external monitor show what your regular desktop is showing? or is everything normal except that your icons disappear?

    as for the lines you see, that is probably an cable issue. how are you connecting your computer to the monitor? what year is your MBP?

    Have you checked System Preferences > Displays > Arrangement > Mirror Displays and seen if that is checked or unchecked?

    Also what MBP do you have and what adapter do you use (if)?
