ThinkPad P50s+ULTRA dock and 4 external monitors

2016-10-22, 10:04 AM

Hey guys,
I've got new P50s (running W10 x64) with Quadro M5000M, and Ultra docking station for it. I want to use 4 external monitors in any configuration, just that they all work. I tried updating BIOS and Docking station, installed latest Intel and Nvidia graphics driver, power management driver.. everything.
I get 4 monitors displayed in Windows display settings, but as soon as I turn on the fourth, one of the others goes dark. Somewhere I read about BIOS setting for Hybrid graphic, but I don't have such setting in BIOS.

 

Any help would be great :)

Thanks!

Solved! See the solution

Lenovo has https://support.lenovo.com/ca/en/documents/pd029622 where it shows that P50s will only support 3 monitors. Considering P50s does not have Thunderbolt, you may have to use a USB video adapter to connect the fourth one.

The P50 does have a Thunderbolt port.

P50 does. P50s, aka refreshed W550s, does not AFAIK.

Sure you can.

 

I had used old http://www.hisdigital.com/un/product2-518.shtml with my W520 (which was limited to just 2 external monitors otherwise), and worked fine with 1920x1200 screen, even for video, despite being USB2 only. With Windows 10 it even gets drivers from Windows update.
