Okay - I'm having an issue with trying to configure two LCD monitors to run as an Extended Desktop display. Here's the situation:

 

You can see from my GPUs (HIS H687F1G2M Radeon HD 6870 1GB 256-bit) that each one has one HDMI port, two mini display ports, and two DVI (1 single link, 1 dual link), ports.

 

My monitors: Main: HP w2338h Wide LCD Monitor. Second: Dell 1908WFP(Digital).

 

The HP monitor has two input ports: One analog VGA, and one HDMI.

The Dell monitor has two input ports: One analog VGA, and one DVI-D.

 

It does not matter how I configure the cabling on these monitors. There are only two ways that I can get both to actually display at the same time. One, I select "Extend these displays" from the "Multiple displays" dropdown in Control Panel>Display>Screen Resolution. However, this does not actually extend the desktop. The only function that it has is to display my desktop wallpaper. I'm unable to move anything from one monitor to the other. Two, I select "Duplicate these displays" from the same dropdown menu. While this displays working windows on both monitors, it's kind of pointless to me to be running the same tasks in two monitors. The whole point is trying to expand my work area.

 

I'm currently using the VGA input on the HP monitor, and the DVI-D input on the Dell.

 

Can anyone help with this?

Not sure if it will help but check your AMD Catalyst Control Center. It should be under Desktop management. If you want the desktop to be across both monitors so one window opened would expand over both monitors AMD has Eyefinity.

Just a guess, but I'd say that the monitors aren't on your desk as they are being displayed on the Screen Resolution page.  If you're seeing the wall paper on both you should be fine.  Press the Identify button.  Then compare to how you see them on the Screen Resolution page.  If there don't match drag and drop one of the monitors so that they do.  Then your cursor should flow from one to the other.

Interesting... From the links you provided, I'm guessing that AMD's Eyefinity doesn't create the old school extended desktop. What it does is trick Windows into seeing the two monitors as one very large monitor. This would be fine, except that the Dell monitor has a resolution of 1440x900, and the HP monitor has a resolution of 1920x1080 - which means that one of the monitors will always be at less than optimum resolution. What I'm actually trying to do is set them up so that, for example, I can open one browser window, drag it to one monitor and display it at full screen, then open another window and view it at fuill screen. In other words, I just want the ability to drag items from one monitor to the other. I'm not sure if there is a way to do this - I seem to remember that in the past, this could be done. I'm also wondering if the different inputs might have something to do with my having problems with this.

Different inputs may be a possibility. In the Catalyst Control Panel there is a section called Desktop Management > Creating and arranging Desktops. There is a detect displays button.  I believe it is there where you set up the 2 multiple monitors. Does it show them? Once you have both monitors side by side, then try extended desktop in Control Panel.
