Cannot make dual screen to work - T510 mini dock (433710U)

Hi,

 

I have two external monitors that I want to use at the same time. I have a Mini Dock (433710U) that has a VGA, DVI and a DisplayPort. I connected 1 monitor to the VGA port and the other one was connected through DVI. When I used the dock, I only get the one attached to the VGA port to display.

 

Can anyone here help?

 

Thanks!

I'm pretty sure you can only drive a total of two monitors (including the laptop screen), unless you have the Optimus model and are running Vista or 7.
W520: 2720QM, Q2000M at 1082/1376, 32GB RAM, 500GB + 750GB HDD, FHD screen & MB168B+
X61T: L7500, 4GB RAM, 500GB HDD, XGA screen, Ultrabase
W550s: 5600U, K620M at 1164/1281, 16GB RAM, 512GB SSD, 3K touchscreen
X200s: SL9400, 6GB RAM, 160GB HDD, WXGA+ screen
TPT1: 1839-23U

Re: Cannot make dual screen to work - T510 mini dock (433710U)

I have the optimus model and i have windows 7 running. it worked just now. i closed the laptop and display transferred to the other monitor but the moment I opened the laptop, only 1 monitor works. I should be fine with only the 2 external monitors working but i had to configure the way the desktop extends. Currently, the desktop extends from the right to the left and I cannot see how I can change this. Is the direction of the destop extension based on the port used?

you can change the direction of extended screen using display property, all you have to do is the drag the screen to the location that suits you.

Also, if you want to use all three LCD at the same time, one of the vga screen may need to be run off the laptop itself, rather than through the dock's vga.
