P51 on ThinkPad 90W Ultra Dock not detecting monitor

Q: P51 on ThinkPad 90W Ultra Dock not detecting monitor

Hi, I'm using a Lenovo P51 with M2200 graphic card and have a docking station 40A2. I wish to connect the two monitors to my docking station, one is VGA cable and another one is HDMI. When I dock my P51 to the docking station, the monitors could not be detected. I tried to configured my bios setting to discrete graphic setting but nothing changed. Try to put shared on dock display also but nothing works. When I connected one of the monitor HDMI cable to the laptop directly without going through the docking station, it works perfectly but I could not connect the VGA cable monitor to the laptop without a converter and it defeat the purpose of having a docking station. Anyone encounter this problem and has a solution for this problem?

Hi, Everyone. Got me a nice little x270 to replace my old x201.  Happy enough with the machine, but getting it connected to my accessories (monitor, keyb, mouse, ethernet) is a bit of a chore. This machine appears to have a "proper" dock port on the bottom.  Is there a compatible ultradock available for the model 20HN x270?  By proper - I mean, Not USB.  A nice dock I can simply drop the machine into when I'm at the home office.. Thanks!

Hi, I am looking for some help, I have a T450 that has been working away on a Thinkpad Ultra Dock with no issues, then all of a sudden it will not charge while docked!! Take it out of the dock and charge directly and it works fine, I tried replacing with a new docking station the exact model but again it does not charge the laptop while in the dock, I have switched out the battery and it is still the same. I have fully updated the BIOS etc and still have the same issue, I tried updating the Ultra Dock firmware but run into issues as the firmware update will only run while docked and also has power, but as the laptop is not detecting power I cannot proceed , I tried updating out of the dock but it does not proceed either as it cannot detect the docking station. Everything else works via the docking station HDMI, USB, DVI, Ethernet  all working perfect, has anyone came accross this issue?

I have a W541 and it always worked well with the dock and dual external monitors, that is until the firmware was updated by Lenovo System Update to the Latest Version: 2.33.000 about a week ago. Now when you boot the laptop in the dock, the post shows on the two external monitors then they go black and seem to disconnect as the power saving icon shows on both monitors. If you undock the laptop at this point and immediately re-dock, the two monitors light up and no more issues. While this isnt a huge issue, it is very annoying since it always worked properly before the update. Any suggestions on a possible fix are much appreciated. Thanks in advance.

Incidentally in this configuration, when I closed the laptop screen this monitor worked.  Also on a related note, the Nvidia Quadro P500  is sitting idle as the Intel UHD 620 is doing all the work.  How can I control this? Thanks for any suggestions. Sal

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.

Yesterday, I updated my T450s and, among other updates,I updated the Ultra Dock 90W firmare to version 2.29.00.  Afterward, when the laptop is docked, with the cover shut, and I try to power up the unit, it won't do so.  When I open the laptop in the dock, the power indicator is green and there is a green light on the function key.  No matter what I try, the machine won't power up after this.  If I force it to shut down and then try to power it up open instead, it powers up normally and both the laptop screen and the attached monitor work and, if I close the cover after, the attached monitor still works.  Obviously, I can use the machine docked with this work around, but I can't figure out why it won't work when I try to poweer it up closed.  I subsequently updated to version 2.30.00 and the behavior continues. What am I missing here?

I'm using a Lenovo Thinkpad Ultra usb 3.0 dock (40A8) with two 1080p monitors (HDMI + DisplayPort). Using the display on the laptop as my third monitor. I have my USB mouse and keyboard plugged into the dock as well as headphones and gigabit ethernet. I also have a second gigabit ethernet dongle plugged into one of the usb ports on the dock. The dock is paired to my Thinkpad P52 workstation. My issue is that while I'm working my display will freeze (mouse, keyboard still responsive on laptop monitor). Then I'll hear the USB disconnect sound, my screens will go black, then they'll come back a few seconds later as if everything is normal. My network connection drops momentarily as well. At first this was just annoying but I've recently moved over to a soft phone and now this causes big problems. When the dock 'restarts' I lose my audio connection to the phone and the brief network connection drop causes my call to drop. I've tried all the basic stuff such as updating the DisplayLink drivers to the latest, turning off USB selective suspend in power settings, using a different usb port. Is this problem specific to my dock or is anybody else experiencing this issue?

I have just taken delivery of a T470p and have done a fresh install of Windows 10 Enterprise and updated that to version 1703 build 15063.540. The T470p replaces an aging X240. I used the X240 with a ThinkPad Ultra Dock type 40A2 (P/N SD20F82750) with 2 ThinkVision LT2452p monitors attached via DisplayPort. Everything worked reasonably fine with the X240 docked - both monitors ran at 1920x1200 resolution. I'd get the occasional problem where I'd have to open and close the X240's lid to force it to realise it was docked, but I could live with that. But...if I dock the T470p then neither monitor works. Both monitors' power LED turn green when I dock the laptop (so I assume the dock and the monitors are talking to one another) but they then turn orange and there isn't a picture on either monitor. If I unplug one of the DisplayPort cables from the Ultra Dock one of the monitors gets a picture, but as soon as I plug the cable back into the dock the monitor goes blank. Is this a known problem? My employer are about to order 40-50 T470p laptops but if we need to purchase new Ultra Docks as well I think we will have to have a rethink. Kind regards, /Neil

Hello, I recently bought the Ultra Dock 90 for my T450s.  I have one external monitor currently connected through the dock.  When I push the power button on the docking station (laptop lid closed) to turn on the computer, the computer turns on, but the external monitor does not engage.  When I lift the laptop lid, there is no image on the laptop screen either.  The laptop is on, but does not respond to any key stokes on the actual laptop.  I then have to do a hard reboot using the power button on the laptop. If I initially power the laptop by lifting the lid and hitting the laptop power button, the compter boots and my external screen works.  I can then close the laptop lid and everything is fine. I know the power button on the dock should power the computer and external monitor on.  I am guessing there is a simple solution to resolve this, but I am not a computer person and need help. One thing to note - when I lift the lid after trying to power the laptop through the dock, I see that the Function Green Light is illuminated.  Not sure if this information is helpful in determining the problem. Please help! Peterrabbit33

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.

Have been happily running windows 10 - with dual monitors, but since a recent update, the system once re-docked will no longer re-detect that it using different monitors. Previously i could use it:1.

Then dock it and resumed:     it would     a) switch to 1920 x 1080, and     b) also detect and display on the second monitor - no intervention required. Now, it remains in it's prior "state" (it neither changes state nor outputs to the second monitor) - only outputting to the first external monitor - but at 1600 x 900. Thus since a recent change, it is not "re-detecting" the "change in state" on resume, ONLY when i now do a full restart. The update may have been a Windows update, but on the same day i also installed a Toshiba Dynadock - with dual display port support. I have used the Lenovo system update to update the driver - now it is at 10.18.10.4425 - and as the driver loaded the monitors re-detected, and corrected - but later the problem is persisting. Does anyone know how to force the driver to re-detect on resume not just on restart?

 When I connect my Thinkpad P50 to my external monitor (Samsung C34F741) directly using the mini Diplayport (connector on the side of the laptop) everything works fine. The resolution 3440x1440 @ 100 Hz and sound on the monitor speakers all work flawlessly. However, when I connect the same external monitor to the Displayport of the Lenovo Workstation Dock (using the same cable), the video works fine (same resolution and refresh rate as above), but the audio on the monitor speakers lags behind the video. The lag is at first barely noticable but increases as time passes, eventually getting out of sync a few seconds. I have the latest nVidia drivers and the latest Workstation Dock firmware installed. I am suspecting the external Displayport on the docking station is not capable of driving the high resolution at such a high refresh rate. Is there indeed a difference is specs between the laptop's Diplayport and the Docking station's Displayport? Can anyone offer any suggestions? Thanks.

I am using a ThinkPad USB 3.0 Pro Dock (40A70045SW) with my Lenovo Thinkpad X1 Yoga (3rd).I have a BenQ BL2420PT connected to the dock via DisplayPort.I am running windows 10 Education 1903 and use Lenovo System Update to keep my drivers up to date.My DisplayLink Manager version is 9.0.1809.0 Every two minutes or so, my screen goes black for 3 seconds and then comes back on. This does not happen when the screen is connected directly to my laptop via HDMI. Is anyone experiencing similar issues with their Pro Dock? Thanks a lot for your help!

When I put my P70 on the dock station and I boot.  I'm not able to see the screen that boot on my Monitor.  I have a DVI connector. I'm able to see the Windows screen when the boot ended, but not the boot menu.  I been in the BIOS and change the setting from THINKPAD LCD to all monitors (3th one). if I want to see the boot menu, I have to open the p70 screen and close it after the boot.  I had no problem with my T510 and my monitor. Do I have to change to a Displayport cable ?  thanks

Hi Guys! We got 6 Thinkpad E550, all with OneLink Pro Docks.All of them are connected with one or two external Monitors (only DP or DVI).From time to time the Monitors starts flickering/blinking black. Its not reproducable. I've already patched all drivers and firmwares. OS was Windows 7 (64) and is now Windows 10 (64). Problems still exists - ON ALL SIX DEVICES, different monitors, cables ect..Actual firmware seem to fix exactly this problem on x1 carbon notebooks:https://download.lenovo.com/ibmdl/pub/pc/pccbbs/options/tp_onelink_pro_dock_fw.txtPlease release a firmware with fix for E550!

Hallo, ich habe seit einiger Zeit das Problem, dass der externe Monitor, der per DP an den Pro Dock und zum T460s angeschlossen ist, sporadische Aussetzer hat. Der Monitor meldet dann "Kein Signal", der Monitor des Notebooks "bleibt da".Ich habe nach Recherche gelesen, dass solch ein Problem bekannt ist und an der Firmware der Docking-Station liegt.Die FW ist aber mit V 2.33.000 anscheinend am aktuellsten Stand.Das Aussetzen ist nicht reproduzierbar und tritt unterschiedlich oft auf. Auch die Dauer, wie lange der Monitor schwarz bleibt ist unterschiedlich.Win10 Pro, i7-6600U, 4k Monitor über DisplayPort (am Dock), Netzteil (auch schon gelesen): 90W, 20V (Rev: D, Rev: 400).Gibt es dazu Lösungen? Ziemlich nervig, wenn währen der Arbeit plötzlich der Monitor öfter "verschwindet".  I´m sorry! I don´t know why but language was automatically changed to English! T460s on ThinkPad Pro Dock, external monitor (4k) connected via display port to dock.Sometimes the external monitor got black and reports "no signal". This happens sporadically, I am not able to reconstruct this. I´ve red, that an old firmware of the Pro Dock can cause this error, but the Verison 2.33.000 seems to be the newest. I also checked the AC-supply (I´ve red, that a wrong supply can cause this "blackout", this is the 90W / 20V supply which should be okay).Win10 Pro, i7-6600U, 4k monitor via DisplayPort (connected to ProDock), AC-supply: 90W, 20V (Rev: D, Rev: 400)Any suggestions?Thank yo...
