Running gauges on second moniter

Hi,

I run the PFD, MFD,  Engine gauges, and the lower display on a second LCD.  I don't use the default setup be clicking on the display and clicking on the + sign and then undocking.  I don't favor this because then you lose the display on the main panel.  I have the displays on one window which I use on the secondary LCD.  The problem I'm having is that I have to keep the primary screen on the 2D panel or my secondary screen's displays will not update.  They stay frozen till I put the primary display back to 2D panel.  The vc will not update my secondary displays.  Is there a way to get around this?

Thanks in advance,
