Using four monitors (three external plus internal) on a T580 + Ultra Pro Docking Station...

2019-03-12, 21:37 PM

Hey Lenovo Team,

 

I have a T580 laptop connected to a Lenovo ThinkPad Ultra Pro docking station. There are two monitors connected via Displayport and a third (which is actually a projector) via HDMI. I read that if you were to use three external monitors on a docking station, that you need to get an Ultra Pro Docking station, but I didn't know if that meant three not including the external display. As of now, I can't get the extended desktop to display on the projector, unless one of the other monitors or the built-in monitor on the laptop gets disabled. On the Intel Display software, I am only given three monitors that I can configure, even though there are FOUR on the pull down list. In the Windows Screen Resolution settings, you can see there are four monitors detected, but the fourth one, you can't do anything with and it says it's not active. The graphics drivers software, BIOS, and Ultra Pro Docking station firmware are all up-to-date. I tried configuring the other monitors' resolutions as requested on the support site for resolutions/refresh rates supported (they are all 1920x1080 @ 60 Hz) and yet I still can't get the fourth monitor to work.

 

I'm not sure if there's a BIOS setting that needs changing or what I need to do to get all the monitors to work or if, in fact, you can't get the three external monitors plus the internal laptop monitor to work.

Could someone provide some assistance or suggestions to get the monitors working? That would be appreciated!

Solved! See the solution

Hi JayBCTTech,

 

I think you're battling uphill with that. The T480 spec and Display Video matrix both say three monitors max.

Thank you for your reply, bananaman. I checked the T580 PSREF and it said it supports three independent displays and also the docking station support three displays. Does that not include the laptop itself and does that mean when there's three monitors connected, that the laptop screen gets disabled?

Yes. This graphics and processor combo can support three monitors total.

 

Hope this helps!

Did you ever figure out a solution to this? I'm trying to run four displays -- two external DP, one external VGA, plus the laptop screen. It doesn't work by itself with the 40AJ dock. So my next thought was a USB to VGA adapter. I've already tried one thing on Amazon, but it doesn't work. Is this even possible? My issue is that when I open the laptop to do a video call, the VGA display turns off and all my windows get screwed up and moved around. I'd like to avoid that by having the laptop display on at all times.
