Sorry I read the whole thread rather quickly. My mind was occupied by all the talks about docstations and triple head monsters. LOL So... OP... do whatever Xspurt said!
You should have a driver disc with the adapter and then it is PnP. All you need is to set it up in properties
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.
One suggestion i have is you will need to put in a more powerful power supply if running additional monitors otherwise you can do damage to your hard drive. Standard power supply units aren't strong enough to handle the additional video cards/monitors. I learned that first hand.
I am scratching my head. This is a discussion on a laptop. Why would an additional graphic card and a more powerful power supply come in to the picture?
Because your laptop's power suppl is made to handle the laptop and an additional monitor, NOT an external video card to expand to 3 monitors therefore you need an more powerful power supply or you are going to toast your hard drive
Where does your external video "card" plug into on the laptop? Want some clarifications. Any specific make/model?
