Solve : Dual Monitor's?

Answer»

Hello,

I have a Dell, with Windows XP.  I just purchased another MONITOR and have a dual adapter which i plugged into my tower.  When i do this, both MONITORS display my desktop which i only want to extend my desktop to the new monitor.  I went into my display and selected to extend desktop but nothing happened.  I have a Radeon x300 series as my default monitor.  I'm not sure if i need to get a new video card and if i do, what kind should i get?  Can someone help me?

Frank What do you mean by dual adapter ? ?
Your VID card needs to support 2 monitors to do what i think it is that you want to do... Quote from: Katman_09 on January 15, 2010, 05:30:30 PM

That's not a monitor, it's a display adapter.I have an adapter that has to female ends and one male end so that i can plug both monitors into my tower.  I've never dealt with my vid card, is it just like popping out the memory and putting a new one in?

As for the Radeon x300 series, yes, i know that's not a monitor, that shows up when i go into properties and then settings for my display.  I figured that had something to do with my problem so i WANTED to be sure i listed that.  Quote from: Katman_09 on January 16, 2010, 06:27:02 AM

That just allows you to show the same thing on 2 monitors. To extend your desktop onto a second monitor you need a display adaptor ("video card") that has provision for using 2 displays independently.

In other words, your video card must have two connectors so that two monitors can be connected directly to it.  Many cards have two types of connectors, or ports.  The types are VGA (also called D-Sub) and DVI.  See http://www.microsoft.com/athome/organization/twomonitors.aspx for an image showing the two types of connectors.

If your card only has one connector, you can either replace it with one that has two connectors or add a second video card in a PCI slot. Radeon x300?
There a many model of this.
Some have the extra connector.
Which model exactly?
