Dual monitor issue Lenovo x220

I recently purchased a Lenovo X220 and I am attempting to setup a dual monitor with it and a Samsung Syncmaster BX2331 monitor. When I change the setting to extended desktop on the secondary monitor the laptop monitor starts having issues. The useable space becomes bigger than the actual screen so I can scroll up and down while on the desktop. It will also scroll left and right and the desktop icons will move over onto the secondary monitor. The laptop has a resolution of 1366x768 and the monitor is 1920x1080. I am trying to explain the issue the best I can but it's a little hard to explain.

I know what you mean, it happened in XP when you set the screen resolution larger than what the screen was capable of. What cable are you using the connection to your secondary monitor? On the secondary monitor, press the auto calibrate button, or it's equivalent, and then unplug the VGA/HDMI cable and plug it back in see if that fixes your problem. it's also worth trying going into the settings and checking the button that says "hides modes not supported by this monitor" If you don't know where that is, right click on the desktop and click "screen resolution" then click advanced and at the bottom of that pop up you should see that check box. Those are the first things to check.

I am using a displayport -> hdmi cable. Auto adjustment is not available with this cable apparently. I couldn't find the "hide modes not supported by this monitor" but the external is set to its native resolution.

Is it an nVidia card?

I am just using the IGP HD3000

Browse the settings and see if there is an option that says "overscan" and turn it off.

I am having the same issues with a new x220 connected to a Samsung Syncmaster 24". I am using the VGA cable for connection and the driver is the Generic PNP Monitor.

Anyone figure out a solution? There is no "overscan" option even when you drill down into the Intel Graphics & Meida Control panel.
