Great feedback.
The reason for the additional 3rd monitor (I currently just have my laptop screen + a monitor running off VGA Port) is for coding work.
When coding I need to see my code window + charts + another screen for pop up windows and odds and bobs. ATM, working off only 2 screens is difficult, especially as the coding window is quite large.
I'm not requiring the additional monitor for trading and if it were, would not be a hassle as I'm not into frequent intraday trading, mostly I'm longer term, hold for several days.
As an aside I actually run 4 laptops + 4 additional monitors off the VGA's, but only one of the laptops is for coding. The other 3 laptops are Trading (no testing, just pure trading), Internet/emails plus another runs Amibroker.
