External monitor black with a only a mouse pointer

Hello,

 

I have a Thinkpad connected to an external monitor through a docking station. When I start up, I get the Windows is Starting screen on the external monitor, but then I just get a black screen with the mouse point - ie I do not get to the login window. I'm able to move the mouse around fine but I'm not able to bring the login window to the screen.

This only happens when I'm connected to the external monitor. If I start up the notebook alone, I'm able to get to the login window and login OK.

Any advice on how to fix this?

 

Thank you

Jamsta

Hello and welcome,

 

If you'll indicate which ThinkPad (and what operating system, OS revision, etc...) we can move your post to the appropriate forum.

Hi Z

Thank you for coming back to me.

 

It is a ThinkPad T440s.

I'm running Windows 7 Enterprise,

and the monitor is a Samsung S27E450.

Re: External monitor black with a only a mouse pointer

Hi,

Just to add to this - I managed to get a display on the external monitor, but only by keeping the notebook open (ie using the built in screen as well, which is not what I want to do). I did this by first starting up the notebook in the docking station but with the monitor cable unplugged initially, and then plugging it in afterwards.

 

But, I then couldn't get the image to display correctly on the external monitor. All resolution settings were distorted.

So I went back over the same steps but now I just get a windows icon on both screens.

In short  - from scratch I need to understand how I can have the notebook connected to a montior through a docking stage, just making use of the montior (and not the screen built into the notebook), and with the screen displaying a sensible resolution.

Hello Jamsta,

 

did you ever resolve this?  If not please try the following; in the BIOS Config -> Display menu select the display option which suits your setup best as opposed to the default ThinkPad LCD, this should then enable you to boot with the ThinkPad display remaining blank.
