W520 wont display 2 external monitors and laptop screen

Hi everyone.  

I have previously had 2 external monitors working as well as my W520's screen, so 3 screens in total.  A few days ago  Windows 7 crashed with a BSOD and now I can only connect 2 screens at once.

 

Everyhting seems to be connected correctly as far as i can tell

This is the error I now get when trying to activate the 3rd screen.

Is there another driver I need to install to reenable the laptop monitor to work along witht the two external screens?

 

Any help is appreciated.  

Like the song says... 'you dont know what you've got till its gone'.

 

Thanks

shane

Why isn't the second Acer external monitor (2 of 2) "checked" as well?

 

Don't you want all three screens in use??

 

How DID you have your monitors connected before the BSOD problem caused your current situation?  Do you have the two Acer monitors daisy-chained via DP from the DP connector out of the K1000M on the laptop?  And you were also using the laptop screen as the third?  If so, I'd think that all three boxes would need to be checked in nVidia Control Panel.

Sorry.  that is the error that I get when I select the laptop monitor.  I can only choose two monitor.

 

everything is connected the same way as it was before the BSOD.  the monitors are connected via a dock.  they are not daisy chained.
