Can I clone display on a T510?

[What]

Hi guys.

I have a T510 with a mini docking station, with one external monitor plugged into the DVI port of the docking station.

I want to clone the laptops display, not extend it, is there any way I can do this? I can't find the option anywhere.

Any help would be greatly appreciated.

If you use Windows 7, then pressing Win+P should give you a selection between cloning and extending.

If you use Lenovo Presentation Director, you can define a scheme to clone the display (if one isn't defined already).

If you use the standard Windows display settings, when you select the second display, untick "Extend my desktop" and it should revert to cloning.

Thanks so much for the reply. I am using Win 7.

Win+P gave me the option to 'duplicate', but when I did, my external monitor powered off and my laptop gave me a warning "this is not the optimum resolution for cloning displays, 800x600 is the optimum blah blah"

I am using the windows display settings and I can only select 'extend display', 'show desktop on 1', and 'show desktop on 2'

I have to pick one of the three, can't just untick extend unfortunately.

Any ideas?
