Thinkpad T410 and Mini dock 4337

Hi

 

I'm trying to figure out whether the mini dock 4337 supports triple display configurations. There seems to be confusing information in your documentation:

 

http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-76617 - This page says that with Optimus enabled systems, triple display configurations are supported.

http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-72871 - This page says "any two of the three video ports can be used simultaneously"

 

Which one's correct? Or am I reading them wrong? My thinkpad T410 has Optimus enabled.

 

Second question: Using a DVI cable to connect the mini doc to the external monitor doesn't work. In Ubuntu, it detects the monitor is connected, but cannot send the display (even if I have just ONE monitor connected - via the DVI cable)..

 

Very frustrating.

 

Please help

 

Regards

Re: Thinkpad T410 and Mini dock 4337

The triple display includes the internal display, so it can support 2 external displays through the Mini Dock 4337.

If you are using displayport, the DVI port is automatically disabled.

Can you tell me a little bit about your LCD setup?

Re: Thinkpad T410 and Mini dock 4337

Thank you for your reply.

 

I have the thinkpad T410 docked. I believe I have Optimus enabled.

 

Monitor 1: Connected via VGA

Monitor 2: Connected via DVI cable (such as this one: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4558913&CatId=4465)

 

I have nothing connected via DisplayPort.

 

I have tried Windows XP and Ubuntu (12.04 and 12.10). 

 

Ubuntu detects the two external monitors, but is unable to send display to the monitor connected via DVI-D cable.

 

In fact, even if I disconnect the VGA cable, the monitor connected via the DVI cable doesn't get a display.. Is it the cable? 

 

Regards

Re: Thinkpad T410 and Mini dock 4337

I see, this could be the issue with drivers, since optimus is not supported in Win XP (not sure Linux supports it either).

Can you install Win 7 and test the same configuration?
