Q: T470s and Ultra Dock 40a2 dual 4k display port monitors not functioning

I am trying to connect two Sceptre U27 4k monitors via display port to the Thinkpad Ultra Dock 40A2 and i'm not having any luck. With a Thinkpad T470s) I can get 1 working but the other monitor just doesn't see a signal. The only setup i've gotten to work is one monitor at 4k @ 30hz on a Display Port and the other at 1920x1080 via DVI I have tried:both display port, 4k @ 30hz (<--- what i'd like to get working since both at 60hz isn't an option with this dock I don't believe)one display port, 4k @ 30hz, one hdmi 4k @ 30hz (via hdmi on the back of the dock)one display port, 4k @ 30hz, one hdmi via hdmi port on the side of the laptop Is anyone familiar with what magic combination of cables and ports would allow me to run both 4k monitors at 30hz, via the two display ports at the back of this dock? I would think updating the docks firmware may help ( https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/ThinkPad-Pro-Dock-ThinkPad-Ultra-Dock-or-Thin... ) but there inlies another issue. Our corporate image on these laptops is RHEL 7.5 and I do not see an option to flash any firmware available from linux unfortunately. Any help would be greatly appreciated.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I'm thinking my best bet may be to use a Display Port to USB-C/Thunderbolt 3 cable for one monitor and the docking stations display port for the other.

My company has issue me a Lenovo T470s and an Ultra Dock to replace my existing equipment. I have two external monitors connected to the docking station with display port cables. The problem that I am experiencing is that if the laptop is docked and the cover is open, I get video on the laptop display and one external monitor. The other external monitor gets no signal and goes to sleep. If I close the laptop cover, I get video on both external monitors. A co-worker told me that this was working as designed and that the solution for getting video on all three monitors was to connect one external monitor to one of the display ports and the other to the DVI port. (He hadn't tested this configuration and is using two display ports with the laptop cover closed.) I tried my coworker's suggestion and got the same result but prior to switching to DVI, I downloaded and installed the latest(?) driver for the HD Graphics 620 adapter from this website (lenovo.com) and that seemed to solve the problem (when using two display ports) but after shutting the laptop down, I had the same issue the next day. What I want, is to have the laptop cover open and still be able to use two external monitors and get optimal resolution on all three monitors. What's the best configuration for achieving this? (Don't guess, like my co-worker. Give me something you've tested and that you can confirm that it works.)

I've read that using a T470s with the USB-C (40A9) 40A90090 Dock connected to 2 Display Port Monitors has problems charging via the USB-C cable and that you also need to connect an external PSU to the laptop for power. I'm in an office setup, so the monitors would be 1080p. Can this be confirmed before I purchase?

Hi guys, I'm hoping someone here can help me with my ever annoying problem. I have a T450s running on Windows 10 64-Bit. Latest Intel Drivers. I have an 40A2 Lenovo Ultra Dock. The following configuration is coming out of the dock into the monitors. Channel 1 - DisplayPort (dock) to Mini-DVI (monitor 1)Channel 2 - using DVI (dock) to DisplayPort (monitor 2) Channel 2 is not outputting any video signal at all. Intel's software is not recognising another monitor at all. Their DisplayPort Topology is showing 1 DisplayPort (this could be because the other is not connected). I've tried both display ports and they both work on either channels. I will be bringing in a DisplayPort to DisplayPort cable shortly to try, but shouldn't my DVI to DisplayPort. Something is amiss and it's driving me nuts. Thanks,Ron

I have a T460 with Windows 10 Pro. It is normally docked in an Ultra Dock. I have an external 4K monitor connected to the Display Port on the Ultra Dock. A week or so ago the display suddenly changed to vertical lines in strange colors. I have determined that the problem is not the cable or the monitor. I changed the DP cable, and the problem remained. When I connect the monitor directly to the mini DP on the T460 it works correctly. This seems to exclude the monitor, the display drivers and the DP driver in the T460 When I connect the monitor to the HDMI connector on the T460 it works correctly. This seems to exclude the monitor, the display drivers and the HDMI driver in the T460. When I connect the monitor to the HDMI connector on the Ultra Dock it works correctly most of the time, but I see occasional flashed of the vertical lines. When I tried a replacement Ultra Dock with the DP connector, the problem remained, but the connection between the T460 and the Ultra Dock was not secure. I returned the second Ultra Dock. All this seems to point to something in the T460 after the DP hardware but before the connector to the Ultra Dock.  Has anyone else seen this problem?

I've been having some issues with dual display with a T440s and a 40A2009US Ultra Dock. OS is Windows 7 64 Enterprise. I two identical Dell LCDs connected to the dock. One via VGA and the other DVI. Both displays are being mirrored and I can't seem to change it. There is only one monitor listed in Device manager.Both external monitors will only display an image if the PC is started closed from the docking station power button. Removing the laptop and replacing it on the docking station does not wake the monitors and there is no image until the laptop is manually shutdown and restarted. I have updated graphics drivers, as well as any driver related to the dock (USB3.0 etc). I have tried a displayport to DVI connector as well, no go. After some research I discovered the firmare may need to be updated. The synaptics package from the lenovo support downloads site gave me the message that my firmware was already up to date. The other fwdphb06.exe that is recommended elsewhere would not update. When I double-click the package there is no install prompt or process being run. There is an external monitor connected to the dock. I have swapped the dock for another, as well as the power supplies for each. I'm stumped. Any idea what my issue may be?

I have a few thousand Ultra Dock scattered across NA. We are in the process of replacing all laptops attached to existing docking stations. Before we can send someone to replace the laptops,we need to know exactly how the monitors are connected to each existing computers/docking stations. The monitor connections maybe VGA, DVI, HDMI or DP, I need to determine how each monitor is connected to the computer/docking station. This is so that I can ensure that the correct cables and monitors are sent to each location. We are using a 3rd party software to determine how monitors are connected to computers/docking stations. They use details collected from Windows to detect the monitor connection type and it works perfectly on all computers and docking stations. However, what we have noticed is that on the Ultra Dock no matter what monitor connection type (VGA, DVI, HDMI, or DP) is used, the Ultra dock always shows that they are connected via DisplayPort (DP). My questions are:Is this a known issue with Ultra docks?Is there a way to have the Ultra dock show the true monitor connection type? If so how can this be done?

I have T570 and two same "thinkpad ultra dock" docking stations - one at the office and the other at home- with two monitors connected on each of them (DP & HDMI). At the office, I close the lid (2 screens) and at home I keep it opened (3-screen setup). A while ago it started flickering / blanking external monitors on *both* of them. Sometimes, when computer is left locked for some time (sleep is disabled!) external monitors are blanked and I can only revive them by removing + attaching the laptop to the dock again. I tried firmware updates on dock, driver updates on windows / lenovo... nothing helps. Windows 10, latest updates. I find it weird that two docks would go bad almost simultaneously. What else can I try - it is driving me crazy as I cannot work normally (sometimes it blinks like every minute or so but other times it is OK for more than an hour)?

A:Thinkpad P52S Ultra Dock and 3 External Monitors

As stayed in PSREF, P52s supports up to three independent displays. Laptop's screen includes in this limit, meaning you can use two external displays at that time. When you close the lid, you can use three external displays. To use more, you'll need some sort of USB adapter to increase such a limit. Regarding other question, you can't disable Intel GPU - it's always active and it's always controls screen output. NVIDIA's dGPU can be configured to be used in selected applications, making them to work with higher performance. P52 and P72 for sure have an ability to disable Intel iGPU, giving the control of screen output to dGPU. Probably P1 and/or X1 Extreme have the same feature too.

Checking to see if anyone has had this issue. We have 5 T570 20JW, running the most current verison of Windows 10Pro and since Yesterday (9/18/17), whenever a user undocks their laptop and then redocks it the external monitors do not turn back on and Windows does not recognize the 2 displays either. The only way we have been able to get them to show back up is to either reseat one or both of the monitor cables from the dock or put the laptop into sleep mode and then wake it backup using the docking station power button. It's not the displaying drivers causing the issue, at least not directly as we have tried the most current and the last release and neither fix the issue and as I stated this just started on 9/18 and the most current drivers are a few months old now. My only guess is that it's one of the 5 lenovo updates that where installed yesterday or the latest bios update (See the attached picture). I haven't had the chance yet to uninstall each of the 5 updates because I will need to go download the last version of each of them first, but wanted to see if any one else has had this happen and to forwarn anyone that has one to be careful with the most current updates. Thanks, Joseph

If I'm using both DP ports can I also use one of the HDMI or DVI ports to drive the fourth monitor instead of daisy chaining it? Setup: W550s (Model 20E2CTO1WW)ThinkPad 90W Ultra Dock One DP cable to a Dell U2414H-- then daisy changed to a Dell U2412M One DP cable to a another Dell U2414H-- also daisy chained to another Dell U2412M Both U2414H monitors have DP 1.2 enabled. Thanks,Sam

I have a brand new Lenovo ThinkPad L470 (win 10 pro) and a Lenovo Pro Dock. This configuration does not support two digital external monitors (don't get me started...) I want 2 digital external monitors.  Does anybody know if I will be able to support 2 external DisplayPort monitors if I purchase the Lenovo Ultra Dock?  thanks.

I am running 2 monitors (Dell U2414H @ 1920 x 1080 60Hz) on my ThinkPad USB 3.0 Ultra Dock.  I also have my Yoga 900 monitor on and the desktop is extended to all monitors.  I have a regular issue where the Displayport monitor turns off for 1-3 seconds then comes back on for no apparent reason.  I have searched the internet and the only similar issue I have found suggestes the dock is under powered to run 2 monitors however that does not seem consistent with what other people are doing.  There is no particular application that causes the issue. Can anyone help?  It's very frustrating waiting for the monitors to come back on.

I have a ThinkPad X240 laptop with Windows 8.1 Enterprise x64 installed. Sound plays just fine from the laptop's speakers, and when I plug external speakers into the laptop's 3.5mm audio port they work just fine too.But...when the laptop is docked in my Ultra Dock 90W docking station and the external speakers cable is plugged into the dock's audio port, no sound is heard. If I'm playing music through the laptop's speakers, as soon as I plug a cable into the dock's audio port no sound is heard. I can still use the laptop's audio port to connect external speakers, but that defeats the object of having an audio port on the Ultra Dock.The Ultra Dock has (I believe) the latest firmware installed (version 2.22.000) and I have the latest audio drivers installed: in Device Manager > Sound, video and game controllers > Realtek High Definition Audio > Driver version is 6.0.1.7188 which is the latest available from Lenovo Support downloads.What do I need to do to get the Ultra Dock's audio port working?Kind regards,/Neil PS. Apologies - I mistakenly posted this message on the "X Series tablet ThinkPad Laptops" board. Can a moderator please remove the post from that board?

Hi Nwgarside,
 
Welcome to Lenovo Community!
 
As per the query we understood that you are facing issue with Audio not working from Ultra docking station with your ThinkPad X240.
 
Have you check with different system/Ultra docking station?
Check with running ThinkVantage system update tool, so that it will update all the required drivers and application for your system.
 
Hope this helps.
 
Best regards,
Hemanth Kumar

I have a Thinkpad W540 with a Lenovo Ultra Dock Docking Station (40A20170US). Here is the set up I am trying to get to work:Display 1) VGA Planar PL2010M monitorDisplay 2) DVI Planar PL1910M monitorDisplay 3) DisplayPort Lenovo L2251x Wide monitorDisplay 4) LCD monitor (off) When I have selected Standard Mode under the BIOS display settings, I am able to connect two monitors plus the internal LCD at the same time: one on VGA and the other on DVI, or I can connect one on VGA and the other on DisplayPort.  This allows me to have three displays, including the LCD.  My problem is that I am unable to get a third monitor to work as well.  When I connect a monitor via DisplayPort, the monitor on DVI stops working.  After reading forum posts and whatever else I found online, I learned (maybe I'm incorrect?) that I need to switch to Advanced Mode in the BIOS to be able to use three external monitors.   I then uninstalled drivers (the BIOS instructions state that you are supposed to uninstall graphics drivers before switching to Advanced Mode), switched to Advanced Mode in the BIOS, started up the computer, reinstalled the latest drivers, but now the only screen working is my laptop's LCD screen.  None of monitors are detected by Windows no matter what I try. When I switch back to Standard Mode in the BIOS, two of my external monitors begin working again. My docking station firmware is updated FYI.   Any suggestions ... Read more

A:Unable to connect to 3 monitors to Ultra Dock (Thinkpad W540) in Advanced Mode BIOS Setting

So I fixed the issue for myself and just wanted to post in case somebody else had the same issue.  I took the following steps to fix the issue:[Background: BIOS is in "Standard" display mode to begin with; I had already updated the docking station's firmware first with a program called fwdphb03.exe and then with Lenovo's update utility.]1) In Windows, I uninstall drivers for the Intel Graphics and K1100 dedicated card.2) Restart, go into BIOS, switch to "Advanced" mode under the Display tab.  I also have the option selected to start up on the docks in the BIOS Display tab.3) Booted into Windows (8.1) and it looked like the Intel Graphics drivers were automatically downloaded. I then ran Lenovo's System Update utility to get the latest video drivers.  Under the optional tab in the Lenovo update utility, I selected the "Optimus" drivers and hit download/install.  It installed, and I had to restart.4) Booted into Windows again, ran Lenovo update utility again, and again it had a video driver to install when I checked for updates.  I installed that, had to restart again.5) Booted into windows, checked screen resolution and saw that no external monitors were showing.6) I then decided to get a driver straight from the source.  Downloaded: the following file from  Nvidia: 334.95-quadro-notebook-win8-win7-64bit-international-whql.exe.  I ran the installation, it did a "Clean" installation with everything checked off. It automatically unins... Read more

I have a new T560 (20FH002JUS) laptop which I am trying to use with a Ultra Dock and Dual 27" Dell Monitors both using Displayport connections. When I have the unit docked I cannot set both monitors to 2560x1440 resolution. One monitor will only max out at 1920x1080 while the other is able to scale all the way to 3840x2160. No matter what cominbation I use, the first will not go past 1920x1080. I've updated all drivers to most current, tried the windows and intel display tools with no luck. I have an older T460 laptop as well which I can dock to the exact same setup and it has no issue doing dual 2560x1440 so I know the dock and monitors are functioning properly.  Help

Hello,  I've been having a hard time finding this exact issue. We use T480s with the ultra dock 40AJ0135US. 98% of the machines dock without issue but I have a small stack where the display on the T480s with go dark with a slight flicker as soon as its docked. No external connections are activated and I'm not able to do anything until I undock and the screen goes back to normal.

I'm considering to upgrade my workstation. It would be a T470p w/a 2560x1600 display, 940mx and 4G support. The screen is a Dell Ultrasharp U2718Q. Do anyone know if it supports HDR through the Ultra Dock?

I have a P40 Yoga attached to an Ultra Dock 3.0 USB.  I have/had an HDMI cable coming off the dock to a ViewSonic monitor.  I am getting a maximum resoltion of 1920 x 1080 and colors are not displaying correctly or in some cases not displaying at all.  I found mention on the ThinkPad site that 4K is only supported via the DP off the dock.  So I tried a DP to HDMI cable and that does the same thing.  If I plug the monitor directly into the HDMI port on the laptop everything works great. Why doesn't the dock work as advertised and expected?  Is there a different setup required?
