Hi again All,
I'm still currently having trouble setting up a second external monitor with my Lenovo T520.
This is somewhat of a second part of another thread
As of current, the only functional monitor is the one attached via VGA (port) to VGA on the monitor. I've tried several times using the DisplayPort (this was hooked up with a DisplayPort to VGA adapter which connected to the VGA port of the other monitor), but alas no success.
My questions are:
The T520's ARE capable of mulitple displays, right? (Just want to clarify)
Would a USB-to-VGA cable/adapter work in this case?
and Am I missing any additional software to make this second display work?
The monitors (which could be considered a bit old, but not ancient) have only a VGA input.
Thanks again, any feedback would be appreciated.

I think I'm on to something here.
I did a print-screen to see what was going on, and I came up with a screenshot with both monitors.
This must mean there is an output problem on the monitor.
However, the monitor is perfectly functioning (I have tested it several times).
Could the problem be the adapter?
It's an SVGA to DisplayPort (vice-versa).
Could it be affecting it?
I am not clear on the issue. It appears from this screenshot that both monitors are working. What is the problem then?

What two monitors are being used in the screenshot you provided? Clearly two displays are being used. Is one of them the LCD panel on the T520?
If you have an Optimus based T520, you can drive up to 4 displays.
If you don't have an Optimus based T520, you can drive up to 2 displays.
So if the screenshot includes the notebook LCD panel, you can't drive it and two external displays with a notebook that doesn't have Optimus.
See http://www.lenovo.com/support/thinkpad/optimus-monitors for more information.
What DisplayPort -> VGA adaptor are you using?
