Nvidia GeForce graphics card without Optimus
2560x1440 at 60 Hz in the Nvidia driver set menu (313.96 driver)
2560x1440 at 60 Hz in the Nvidia driver set menu (313.96 driver)
Status: successful, 2560x1440 60Hz tested
Tested with: Asus UL50VF (despite with Optimus, the HDMI port is directly connected to the GeForce G210M), driver: 313.96 and Fujitsu P27T-6 27-inch monitor with 2560x1440.
Instructions
In the Nvidia driver settings, add a new resolution with "Display -> Change resolution, Customize ..., Create Custom Resolution". In our test, a resolution of 2560x1440, 60 Hz, Progressive with Timing "CVT reduced blank" worked without image problems (automatic results in image errors and flickering on the Fujitsu P27T-6). Afterwards you can select the resolution in the Nvidia Control Panel under "Change Resolution".

A forum user apparently connected a Dell 2713HM to his Sony VPCZ1 with GeForce 330M:
First of all I updated the GeForce drivers using the hacked drivers from:
forum.notebookreview.com/sony/342947-my-discoveries-vaio-z-s-hybrid-graphics-252.html
This may put other people off but there has been a lot of work put into these by several people at notebookreview.com.
Then right click the desktop and choose Nvidia Control Panel.
Choose Change screen resolution from right hand menu.
Make sure Dell U2713HM is selected on the left panel.
Choose Customize...
Create Custom Resolution...
Change Horizontal to 2560
Change Vertical to 1440
Refresh rate 40 (highest that would work in my testing)
Color depth 32
Scan type progressive
Expand Timing menu
Choose CVT reduced blank
Choose test
