Q: X1 Carbon 3rd Gen with OneLink+ dock - problem with 2 external monitors

Hello everybody,i am posting here because i really went through the whole www and still i have this issue, which is the following: My configuration is:X1 Carbon 3rd Gen (Windows 10 64bit)OneLink+ docking2 x ThinkVision P27q-10 monitors. The problem:When i connect both monitors to the dock, i get only one running / working.The only way I get both monitors working is if i connect the second one on my miniDP port directly on the laptop. And in this configuration i can have all three monitors working (laptop display + 2 external) Obviously i want to have them both connected on the docking station and use it properly. Thanks in advance for any solutions / suggestions. Dean

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

I'm unable to get my X1 Yoga to detect external monitors when plugged into the OneLink+ dock. This started occuring when my computer upgraded to the creators update. I thought I found a thread of others with the same issue (linked below), but it turns out I was waiting for a fix that didn't apply to me. I'm super frustrated right now. Stuff I've tried so far.1. Updated all drivers using Lenovo Service Bridge (even optional drivers)2. Installed the Fall Creators update preview (after being told it would fix the issue)3. Completely reinstalled Windows4. A Single VGA monitor5. A Single Display Port Monitor6. 6 different cables At this point I'm convinced there's an issue with the dock. There's a firmware update available for it, but you can't install it unless it is actively connected to a monitor (go figure).  When attempting to install, I get the code 255 "Can't connect to Synaptics VMMxxxx DP hub IC" If anyone has any sugestions, I'd greatly appreciate it. It used to work perfectly, then about the time I installed the creators update it started getting flaky, now I can't get it to work at all. Previous thread I was following. Note that I'm linking to a post where they show the dock working (annoying).https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/Windows-10-creator-update-breaks-Lenovo-...

Hi!I just got a new "X1 Carbon 5th Gen - Kabylake (Type 20HR, 20HQ)" and a "X1 Carbon Thunderbolt 3 Dock". I have an external screen connected to the dock and it works fine (VGA connection). I also have an other monitor with display (DP) connection that I want to use. But my computer can't find the other monitor, only the one with VGA connection. Is there any easy ways to fix this problem?Best regards

I have the exact same equipment at home and at work and yet the resolution on my second monitor at work will not go to the 3840 x 2160 that I have at home. Both locations have:1. X1 Yoga (first gen, model number 20FQ002YUS) -- It's the same laptop that I take between home and work2. ThinkPad OneLink+ Dock (model number DU9047S1)3. Two (2) Asus monitors (model number PB287Q) that go to 3840 x 2160 max resolution, connected to the OneLink+ Dock via DiplayPort cables I've been running this configuation with NO PROBLEM at home for the past 9 months.  So I recently purchased a new OneLink+ Dock and two new monitors for my work office and while one monitor will go to 3840 x 2160, the other will not go above 1920 x 1080, UNLESS, I use a mini DisplayPort cable from the second monitor directly into the X1 Yoga (bypassing the OneLink+ Dock) HERE'S WHAT'S BAFFLING: I assumed it was the dock and so I brought the one from home to work and found I had the SAME problem, suggesting it was the second monitor.   But I exchanged the second monitor for a new one and still have the same problem.  The docks are running the most current firmware. I'll send a gift card to your favorite coffee house if you can solve this mystery.  Thanks!

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!

Hello anybody, I got the brand new Carbon X1 with i7-5600U and OneLink Pro couple days ago and I have issues ever since.I have 2 main issues. 1. Laptop alone works like a charm, but when I connect the laptop to oneLink I can't get an image on my second exterior display via dvi nor via vga. The computer finds the screen and name etc, but when I want double or extend or only screen 2 projection nothing happens on the external screen. It keeps saying no input. I have tried to reinstall dock driver, change resolution, updated even bios, still nothing happens. 2. This problem is even more disturbing. If my computer is turned off or restarted while connected to OneLink dock pro, it won't start and freezes at lenovo logo. If I pust laptop to sleep while conected it boots normaly, if i turn it off not connected, then connect it and start it also boots normaly. But when it is shut down while conected it doesn't. Not even if i turn it off while connected, unplug it and turn it on. I have to do reset in this case. Guys I really need help, since those issues make my dock almost completly useless.HELP! Tilen_T

Hey, Funny enough this has nothing to do with the dock itself. Just opened up laptop the other day and in the bottom right it says that "ThinkPad OneLink Dock Attached!" I've tried checking devices as well as looking for a usb port being used in my computer and theres nothing in either place. Just to repeat there is nothing attached in any usb port, in this laptops very short life there has yet to be anything in any usb port so I'm not quite sure whats going on. I have malwarebytes and I ran a scan today and found nothing. Any ideas?Morten Nissov

I recently bought a X1 Yoga as a personal laptop to compliment my Gen 3 X1 Carbon. I istakenly thought the onelink dock would be indentical, only to find they use different ports. From what I can tell, Lenovo does not sell a converter cord. Has anyone run into this issue? Am I stuck having two docks on my desk or should I just convert to a generic USB doc (non-Lenovo)?

Sometimes when I connect the Onelink connector from the Onelink+ dock, the ethernet port is not detected.  The monitor shows up and usb ports function but there is no local area connection listed in the netword adapters.  If I disconnect the Onelink connector from the X1 and reconnect it, then suddenly the local area connection shows up and is there until the next time I redock the Onelink+.   Is this a known bug?  Anyone else having this problem? This is on Windows 7 x64 with all the latest drivers installed from the Lenovo website.

We have a few Lenovo displays we are replacing and wanted to get some USB-C displays for our few MacBook Pro users, but also work with our OneLink Pro & Ultra Docks. Ultra Dock works great with DisplayPort & HDMI. The MacBook Pro's work great with USB-C and Apple's USB to ethernet gets us all set there. The issue is the X1 (gen 3) with OneLink Pro dock. When we setup the dock with DisplayPort it shows the display is connected in the Display Properties, along with resolution and extended desktop, but the display itself shows nothing and has an orange light. We tried 3 different docks and laptops, 2 different P24h displays, and 3 different DisplayPort cables. Confirmed both the display and dock support DisplayPort 1.2. Any idea on what I can do to get this going? So far this is the best display we could find that covers all our bases for our needs.

Running Win10 Pro/64. I've got two OneLink+ units, both yield the same result. The laptop will boot just fine when it is not connected to the dock, but when docked, it will not boot past the screen which says "press enter to access BIOS (...)" when the network cable is plugged into the docking station.  It boots just fine when the network cable is not plugged into the rear of the docking station. There's nothing special with the network or cable (works well with a myriad of other laptops) and the ThinkPad in question has the latest & greatest drivers installed. If a docked boot has already taken place, plugging the ethernet cable into the dock works just fine.  In essence, the problem exists only when the ethernet cable is plugged in during boot.  Does anyone know of a fix?

A few days ago I was prompted to install an urgent BIOS update.  I followed the screen prompts and the system rebooted and flashed the BIOS.  Our company laptops all have Sophos encryption, which requires a separate login prior to booting the OS (Win7).  I've always been able to enter user ID and password information on that screen using the USB keyboard connected to my OneLink+ dock (which is connected to the laptop). Following this BIOS update, I can no longer use the keyboard or mouse (also USB) connected to the OneLink+ dock until the OS boots.  I have to open my laptop, enter my Sophos ID and password on the laptop keyboard, then close the laptop.  Once the OS (Win7) boots, I can use both the USB devices fine.  Interestingly enough, the monitor attached to the OneLink+ dock functions just fine before the OS boots up. I checked BIOS settings and couldn't see anything there that looked odd or out of place.  I also checed Device Manager to see if there were any warnings or issues, and didn't see anything. I tried to downgrade the BIOS to an earlier version, but once you are above 1.23 that is not possible.  I did flash to the latest release - 1.27 - but that did not fix the issue. So I'm stuck with a rather awkward login process which was not an issue until this BIOS version was installed a few days ago.  I've reviewed other post for similar issues but have not found anything that points at a solution thus far...

Hi,
I have just upgraded from an E6410 to an E7440. I have two Dell 2007FP monitors connected via DVI on an E-series E-Port Plus dock. The native resolution of these monitors is 1600x1200 @ 60 Hz and my old E6410 was able to run this just fine. The new E7440 however refuses to see that 1600x1200 is available and has an upper limit of 1280x1024 @ either 60 or 75 Hz. The Intel graphics properties app does show that 1600x1200 @ 60 Hz is a supported mode of the monitor in the Information Center section, but it won't let me select it in the Display Options section.
Anyone know if this is a fundamental limitation of the docking connector on the new 7000 series or if I just have something set wrong somewhere? All the drivers are up to date as far as the Dell support site is concerned ... The machine is running Windows 7 64 bit if that makes a difference.
Thanks & regards,

Sorry - should have come back sooner as my IT guys at work found the "fix". This is a driver update that is for the E7440 but doesn't come up if you search for E7440 updates (???). Anyway, I got the required driver from:

Whilst the link is from the E5540 area, the driver is for the Intel HD4400 GPU that is in the E7440 as well. This has fixed the issue on all the E7440s we have here.

Hello, I just bought an X1 Carbon Gen 4 and need to hook up 2 external monitors which have VGA, HDMI or DVI ports available. The idea is to have a 3 monitor setup (all three monitors with a resolution of 1920x1080) including the Built-in monitor and the 2 external ones. I have bought the OneLink+ adapter that has the RJ45 and VGA ports (4X90J31060) and am trying to set the whole rig up so that one monitor connects to the VGA port on the adapter and the other monitor is connected through the HDMI port on the laptop. The problem is that I can only seem to get 2 monitors going at a time, either Built-in & HDMI or Built-in & VGA. Before I go and buy more hardware (i.e. dock or MiniDP to HDMI/DVI adaptor), I was wondering if what I am attempting is even possible, and if it is, what I am doing wrong. Thanks to anyone who can answer.

When one is connected via VGA both monitors are detected, however the one connected via VGA will flicker or blink off and on. Disconnecting the ThinkPad dock solves this issue. I have tried the following:Uninstalled and reinstalled graphics driversUpdated dock firmwareRun updates on graphics driversChecked different cablesChecked different monitorsChecked different dockChecked different laptopRun Lenovo VGA fix The Lenovo VGA fix would not complete and ended up in error loop. After advice from the internet I unplugged the dock and tried again, but failed. I then unplugged everything but the VGA cable and tried again, but failed. I unplugged all peripherals and tried again, but still failed. Errors include "Invalid AUX device" and"Enable Aux2 Reg Failed".Finally I redownloaded the fix, unblocked everything before unzipping then ran as Administrator, however it all still failed. Any other advice?

The way I read the X1YG1 base specs it supports two independent monitors.  Apologies, but I can't quite parse your post.  Does "apart from laptop screen" mean that you want 3 monitors total, or two and the laptops's display is off?

Hello all, i have the following problem at any X1 4th generation we are using at our company:if you connect the X1 with the OneLink+ always you can see the that "ThinkPad OneLink Plus Dock Audio" is marked with a yellow ! and if you click on properties you can see that the driver is not digitally signed.As i have tried the latest driver and also the latest firmware at the moment i don't have any idea what to do.If i start the system using the F8 key and choosing "Disable Driver Signature Enforcement" it will be shown without the yellow ! but after a restart the ! appears again...Using "gpedit.msc" and switching off to check the digital signature is not an option...And the second problem is that if you use the 3.5 plug at the OneLink+ audio does not work with a headset - if you use the 3.5 plug at the X1 it works...Does anybody have the same problems? I have this on every X1 used with the OneLink+ Dock...Any suggestions - or solutions?Many thanks in advance! Scotty

I could not connect via Ethernet using the TPY (Win 8.1) and Onelink Dock (basic).  With all updated software, the TPY kept trying to connect to the USB3-ethernet in the Dock but could not start the hardware. I received a USB device not recognized which cycled during a session and seemed to screw up other parts of the system. Thinking it was a driver issue I uninstalled all the ASIX drivers and removed all the driver packages associated with the ASIX AX88179 and AX88178 controller   (see:  http://technet.microsoft.com/en-us/library/cc730875.aspx  ). Then ran Windows update which downloaded yet another ASIX package. I downloaded both the Win 7 and Win 8 driver packages from ASIX, unzipped and looked these over.  I modified the *.inf files and deleted all the non-english segments with asian or Russian characters at the end of the file leaving only the English segment and saved these on the C: drive.  (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=131) I reloaded the OneLink drivers from Lenovo.  Ethernet not recognized.From Device Manager,  I tried to update the Ethernet controller driver to the new downloaded, modified Win 8 driver and received the message that the driver was the current driver so it would not update. Instead, I had DM browse for the Windows 7 driver, and loaded that.  Ethernet not recognized. Then I had DM browse for the modified Windows 8 driver.  Thi...

A:One Onelink dock Thinkpad Yoga problem solved.

Wow, glad that you found a solution! Hope you don´t mind if I ask a few questions, just so that I understand better what to do? 1. Would you mind providing a little more info on what you exaclty removed in the Win 8 .inf driver file from Asix? 2. When you mention ´DM loaded the modified driver´, I take it you mean the modified Asix inf driver, not the one you downloaded from Lenovo?3. In your estimation, is the USD2 dongle step required?thanks again.cheers,Olof

Hello.
Hoping you can help me here...
I have an X380 Yoga with the USB-C dock.  I bought 2 ACER monitors, each with 2 HDMI ports.  Using HDMI-to-DisplayPort adapters, I have both plugged in to the dock, yet I can only get one of the monitors to actually display anything.  This is all being with my laptop display in use, so I'm not sure if that is coming into play.
 
Any assistancce/insight you can provide would be GREATLY appreciated.
Thanks,
Barry

Hi all!! I'm trying to determine if I can utilize 3 external monitors in addition to the laptop screen. I have a T480s with a thinkpad USB - C Dock and my current setup is: - DP to DVI adapter from docking station (for one external monitor)- VGA from docking station (for one external monitor)- Built in laptop screen This works perfect but I'm trying to get a 3rd monitor to work as well. I have a HDMI to VGA adapter that I have tried from the laptop to the 3rd external monitor. It doesn't work. If I unhook the VGA from the dock (one of other monitors), the 3rd monitor will work as expected. It seems trying a 2nd VGA is causing the issue. The 3 monitors I have only have VGA and DVI. I'm thinking about buying either a USB C to DVI/VGA adapter OR a HDMI to DVI adapter but before I do that, I wanted to see if anyone knows if this will work. Sorry for the long message and thanks in advance to anyone that can help! Thanks,

Is there any official and correct information about supported multi-monitor configurations with new Thinkpads? I'm trying to get Thinkpad P70 with M3000M + Workstation Dock (with 230W) to display different images on two external 4K monitors (Dell P2715Q), and so far without any success. Using DisplayPort 1.2 cables, no MST. Windows 10. All works fine if I'm only connecting one monitor. Laptop screen and the monitor happily get to 4K resolution @ 60Hz. However, as soon as I connect the other monitor, one of the monitors switches to 1920x1080, and 4K resolution isn't available to choose for that monitor. If resolution is set [email protected] both monitors work, but I want 60.  Tried everything. Switching between Discrete & Hybrid in BIOS, clean Windows 10 install (on a separate drive), different cables etc. Same result.  Looking for explanations, went to nVidia Control Panel,  and it reports that BOTH monitors are hooked up to the same DisplayPort (attached)?! Can P70 drive two external 4K monitors @ 60Hz at all?

Hi all, would really appreciate some help from you all!  I want to connect P50 to two external monitors and have all three displays (p50, monitor 1 and monitor 2) on.  Is that possible without a dock?Monitor 1 is a 21.5 inch Asus monitor with HDMI, VGA and DVI portsMonitor 2 is slight ancient 22 inch HP monitor with only VGA and DVI ports My P50 laptop has HDMI, Thunderbolt, and a Mini displayport connector. Can I connect the P50 to the two monitors and have the displays on all of them (including the laptop) be on?   If yes, what do you recommend is the best way to connect them?

A:P50 display ON plus two external monitors without a dock possible?

First, you haven't mentioned if you have a "discrete graphics" nVidia GPU in your P50. I will assume you do, and I will recommend that you set your BIOS to have Config -> Display -> graphics device set to "discrete graphics".  This will effectively disappear the built-in Intel HD Graphics hardware (from the CPU) which would normally control the laptop screen.  It will instead assign the nVidia GPU to control the laptop screen as well as all externally connected monitors.  You should then download and install the normal latest retail nVidia graphic driver for your Quadro GPU from the nVidia driver download site.
 
Next, you should use both the miniDisplayPort and HDMI connectors on your P50, to connect to the external monitors. You can connect the HDMI port on the laptop to the monitor which has an HDMI source connector, using a regular HDMI-HDMI cable.
 
The second external monitor can be connected to the miniDP connector on the P50, but you will need a proper modestly priced miniDP->DVI cable like this one.
 
That's it. You can use the nVidia Control Panel (installed as part of the normal nVidia driver) to activate all three screens and also to set the desired resolutions on all three screens.

Is it possible to run 2 external monitors with the t460p without a dock? If I need a dock, which one will be needed to drive 2 monitors. Preferably digital. I cannot seem to find any documentation about this.

My Onelink Plus dock behaves very strangely, I cannot use the Ethernet port reliably:I bought recently a Thinkpad Yoga 460 ? after my previous Thinkpad ? and an Onelink plus dock. After docking I have to disconnect and reconnect all cables from/to the dock to make the Ethernet work.After that it works great for a period, but sometimes it loses the connection. I have to unplug again all the cables and reconnect them to make it work. To the dock I attached the following: USB keyboard, mouse, external drive, DisplayPort cable (with DP to DVI adapter) and the Ethernet cable. I am using Windows 10 Pro 64 bit (ver. 1607) from a clean install. Every device in the Device Manager seems to be OK, even the ThinkPad OneLink Plus Dock Ethernet.I have the latest software and firmware.Lenovo Companion cannot find new updatesI have updated the BIOS to ver 1.46.I have also updated the Onelink plus dock firmware (Version: 2.33.000). Any idea? This way the dock is useless.

Hello Everyone, I am new here so please go easy on me.I just bought and X1 Carbon 5th Gen laptop c/w Thunderbolt 3.0 docking station.The problem that I have is that the docking station won't recognise any of the external screens that are connected.I am using two Acer screens (one is connected using HDMI port on the dock and the other one uisng Display port).I have tried by connecting just one screen but nothing.I can see that Thunderbolt software is installed and its connected to my laptop.The laptop will charge through the docking station and also the wireless mouse and keyboard will work fine through the dock.Lenovo recommended that i should update my drivers.So I installed Lenovo Companion from Windows store. But it won't update my system. After clicking on System Update, I will get an error message saying "There is a problem in reteriving new updates for your system.Please try again later".Hence I downloaded all the drivers from support website and installed them manually but my docking station is still not working with the external monitors.The monitors works fine when connected directly to the laptop using the HDMI cable. Thanks in advance for your help.
