New P70 + dock + 3 Lenovo monitors does not work

My setup:

 

Lenovo Thinkpad P70 (MTM: 20ER-003NMD)

Dock: Thinkpad Workstation Dock SD20A06045 / 04W3955 (just installed firmware version 2.33.000)

Displays: Three Thinkvision 24" (1920x1200) LT2452p (MTM: 4420-MB2)

 

I upgraded from a W540 to the P70 just recently and changed the dockingstation with it. The setup is cabled with:

 

Monitor 1&2:

2x Displayport --> Displayport in dock

Monitor 3:

1x DVI --> DVI in dock.

 

Issue:

Monitor 3 will not show a picture, it goes directly to power-saving-mode. I have tried to use the following work-arounds, before writing this post:

*Changed to DVI cable to a new one, also took another DVI just in case = directly to power-saving mode

*Changed to a Display-port cable, had a converter betweeen for Displayport --> hdmi and had a HDMI cable to the dock = directly to power-saving mode

*Changed to a Display-port --> mini-display-port cable and plugged it directly into the Lenovo laptop = directly to power-saving mode (this was my setup with my W540, to get it to work)

 

Question:

How do I get my setup to work? I have installed the latest drivers from the site:

http://pcsupport.lenovo.com/dk/da/products/laptops-and-netbooks/thinkpad-p-series-laptops/thinkpad-p...

 

I have also checked, that the dock does support this setup:

https://support.lenovo.com/dk/da/solutions/pd029622

 

What am I missing? (its frustrating that a new model like the P70 dont autoregister any monitor)

 

Thank you very much in advance. 

 

/Best Regards Kim

Hello,

 

I forgot to mention, I am running Windows 10 Pro 64bit.

Re: New P70 + dock + 3 Lenovo monitors does not work

 

From the chart below, there are 3 banks on the docking station.

 

Bank 1  contains a DP and an HDMI.

Bank 2 contains a DP and DVI.

Bank 3 contains a VGA.

 

To connect three monitors to the docking station, you'll need to connect one monitor to each of the three banks to get 3 displays working out of the docking station (i.e., 1 monitor to Bank 1 - either DP or HDMI port, 1 monitor to Bank 2 - either DP or DVI port, 1 monitor to Bank 3 - VGA port).  

 

That being said, if you didn't want to use the VGA port on the docking station, you should be able to plug the third monitor into the HDMI port directly on the laptop itself and drive your three displays.

Hello Mebsterbball,

 

This helped! Thank you very much.

 

Although aside, I cannot help but wonder why it has been made this way. You should be able to use whatever ports your like(?).

 

Again, thank your for your support.

Re: New P70 + dock + 3 Lenovo monitors does not work

Althought I completely understand what the requirements are for monitors, I still cannot get the more than 1 monitor to work. 

 

I'm also aware of the 4k limitation. 

 

Is 2560x1440 considered 4k for this limitation? My mainmonitor is a S27A850D - 27" 850 Series Business LED Monitor. It works fine as a single mon.

 

That being said, my other monitors are apple cinema displays at 1080p. I can't get either of them to work. Either with or without the samsung hooked up.

I assume you're plugging this into the laptop itself?

Yes I bought the ultra dock with my p70 early 2016 found it ok for elivating keyboard not so good for multi monitor set up just saying using the TB ports on the p70 is another option
