T580, Ultra Dock, External Monitors

Q: T580, Ultra Dock, External Monitors

I have a ThinkPad T580 with the Ultra Dock (40AJ0135US) and I'm wanting to use two external 4k monitors. I found this post (https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/How-many-DisplayPorts-are-available-on-t...) that seems to indicate that this cannot be done, but it doesn't make sense since the dock utilizes two USB-C connections from the T580. Can a DP and USB-C on the dock be used for two 4k monitors? Is there any combination of ports that would allow the dock to support two 4ks? Will Lenovo be releasing a monitor compatibility matrix soon for their new laptop lineup, like this one: https://support.lenovo.com/ca/en/solutions/pd029622#USB-C%20dock ? I appreciate any help!

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!

Hi there,I've got a new T470 and Ultra Dock and try to connect my 2 external monitors via DisplayPort but nothing happens.I tried to update the firmware of the Ultra Dock but it won't work because I got the following error message in den update.log: "Error description: Can't connect to Synaptics VMMxxxx DP hub IC"The 2 monitors were still connected to the Ultra Dock. So I connected one of those monitors vie HDMI and installed the Firmware again. Now I got the current version 2.33.000 installed. But as soon as I remove the HDMI cable nothing happens again. What else can I do? Do I have an issue with my Ultra Dock?

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

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.)

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!

I got my new T580 today, and with it the Ultra Docking Station.It generally works fine except for some minor issues with my monitor still needing DVI, but that is easily solveable. The one big issue I have with it is my mouse:Moving it in circles shows freezes every few seconds, for up to a few seconds at a time! The mouse is practically unuseable as it is.It's a Logitech G500 mouse. Connecting it to one of the Laptops USB ports works makes it work just fine.Connecting one of our cheap default Microsoft mice to the dock also works just fine, but I'd really rather use my Logitech. I tried updating all the firmwares and drivers(OS in use is Windows 10 64bit), but nothing made any difference. The mouse is not only freezing, but judging by the constant device disconnect/connect sounds also completely reconnects every like 30-60 seconds. Using a USB event viewer confirmed that it is indeed the mouse being reconnected.

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)?

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.

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

 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.

Hi psubsee2002, Can we test the VGA input of the monitor and VGA cable to make sure they are not the root cause. I would like you to get a known working VGA cable and a knonw wokring monitor. If the VGA input of the monior and VGA cable is good, pleas try the following: Go into BIOS -> Advanced -> Device Confirugation -> Disable "Hybrid Graphic." By doing this, it will only allow the unit to use your Nvidia video card rather than your onboard Intel graphic and Nvidia. Since you're connecting to multiple monitors, lets use the Nvidia graphic which can handle graphic at better rate.  Thank you, -Tenzin

Hello! I have a HP Spectre i5 (http://store.hp.com/SwedenStore/Merch/Product.aspx?id=F4W32EA&opt=UUW&sel=NTB) which i am trying to use two external monitors with. I use this travel dock for connectivity: http://www8.hp.com/emea_africa/en/products/oas/product-detail.html?oid=10127478. What I am trying to do is connect two VGA monitors to the travel dock, one directly into the dock's VGA port and one with a VGA->HDMI adapter into the dock's HDMI port. However, i am not able to discover both external monitors when doing so. Before i spend (even more) time on trying to solve this, is this even possible? If not, what alternatives do i have? I was thinking maybe i can connect both monitors to one VGA->HDMI adapter each and then use something like this into the travel dock (http://www.lightinthebox.com/sv/hdmi-hane-till-dubbla-hdmi-hona-1-2-vags-splitter-kabel-adapter-for-... <-- that one is just the first i got on google, but you get the point).What i want to achieve is when i have my laptop stationary and plugged into the travel dock, i want to extend the screen over my two external monitors. I do not neccesarily need to have the laptop's internal screen active while doing so.  Thanks in advance!

Hi, The travel dock is usefull for you when travelling around. It has ports for you to connect to ONE external monitor or ONE projector using VGA or HDMI (not both). It won't help you to connect TWO external monitors. Full stop. You need a proper dock which supports DisplayLink to be able to have 2 external monitors. I did post few tests last year. Regards.

Based on the dock specification I can use only DP+VGA or DVI+VGA and both setups should be able to support 1920x1200 on both monitors. What I tried:- turning everything on and off - update of graphics card driver- update of dock driver- DVI+VGA and DP+VGA (blurry image on VGA)- DVI+DP (not working at all) I bought Pro Dock based on the documentation here, so I expected 2 external monitors at 1920x1200, but I can achieve that only when the second monitor is not connected to dock, but directly to laptop using MiniDisplayPort-DisplayPort cable, but that ruins the whole purpose of having a dock. Any help highly appreciated!

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'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-...

Hello,
I have a Latitude E7470 for work and when I first started using it with my docking station to external monitors, I was noticing a similar issue as was brought up in the thread linked below. One of my two external monitors (seemingly randomly) would flicker once, or periodically to a point where it was distracting. Additionally, I have seen the graphics card crash a few times after such problems appeared.

I implemented the "fix" that was linked (and marked as the answer to the thread) over lunch about a week ago, and more things went haywire from there. Basically, at this point I am unable to connect to any external monitors through the docking station. I have resorted to having a single monitor connected via HDMI, but it is hardly conducive to working and I would really like to have my multiple monitor setup back (even with the flashing problem, at the least).
Is there any way to undo the actions I have run, or is there a more up to date fix for this issue?
Link to "fix": 
Any response and guidance would be greatly appreciated. I'd really like to not have to resort to getting a different style (USB 3.0) docking station if I can prevent it.

A:Latitude E7470 External Monitors with Dock Problems

Yes I am referring to one of the external monitors flashing constantly when it resumes.  This has happened with previous Latitude models and you will see a synaptics VMM update within the video section of the 7450 that fixes this issue.

Equipment:Lenovo Twist s230uTargus DisplayLink2 x Lenovo e2224 monitors I've seen this issue several times with the same or different machines on the web but have yet to find the my fix.  I have my monitors set up in extended view and at least one will flicker with lines and/or go black for a few seconds randomly.  Particularly after the computer has locked.   I have: - Checked drivers for USB, Displays, the dock - Completely replaced the dock - Replaced all wires and cords - Tried a different USB port - Confirmed BIOS version What I have noticed is the displays are okay if any of the following is done: - The laptop is unplugged and on battery - The resolution is changed down to 1400x900 from 1920x1080 - The display is twinned instead of extended view. Anyone have any further thoughts?

I recently purchased the P52s and the Ultra Docking station.  I am dual booting Windows 10 Pro and Ubuntu 18.04.  I have dual 27" monitors connected to my Ultra docking station, as well as ethernet and power.  The Ultra connects to my P52s via USB-B Type -> USB.  Inititally all was well, but after a week or so,  my Ubuntu stopped seeing the dual monitors, even though the ethernet from Ultra continues to be picked up.   In Ubuntu the "display" only shows the built in laptop display and I cannot force it to detect external monitors. I have updated all the Lenovo drivers via the Windows updaters.  Previous threads seemed focused on other Lenovo products and didn't help me here.

Hello all, As the Yoga 720 15'' has only one Thunderbolt port, with no other ports for connecting more displays, I'm looking for a solution for connecting two monitors through this single port. The problem is that the Thunderbolt 3 to dual DisplayPort adapters do not seem to be working on this laptop for some reason according to threads on this forum. (although it has the appropriate hardware I suppose?)I saw a solution using the Lenovo Thunderbolt Dock, but it's quite expensive... I thought to myself: suppose I have two monitors that supported DisplayPort daisy chaining, could I use this ability and connect them to the laptop? Connecting one monitor directly to the laptop, and then connecting the other monitor to the first one using daisy chaining. Like so:Yoga -> Thunderbolt to DispalyPort adapter -> Monitor 1 -> DisplayPort -> Monitor 2.  I couldn't find any info about this method (only that it is possible on the XPS 15 which also has Thunderbot with two lanes only...)  Have someone already tried this method? Or could try it? (pretty please... )Or could at least tell me if it is possible? I'm really looking forward to buying this laptop and this is the main reason that stops me...  Note: I am aware about the bandwith limitations. I plan to use only two 2K displays. Thank you!

I have recently received an upgrade laptop at work. On my previous laptop (ThinkPad, unsure of model), I was able to connect one external display monitor directly to the VGA port on the laptop and an additional external diplay monitor to the ThinkPad Pro Dock station VGA port. I prefered to use these two screens with my laptop closed on the docking station, but could also open the laptop on the dock and have a third screen available. ISSUE: With my new ThinkPad (T440) there is no VGA port on the laptop. I have purchased a simple HDMI to VGA Converter Adapter - see link:https://www.amazon.ca/VicTsing-Gold-plated-Converter-Ultrabook-Devices-Black/dp/B016LVT51G/ref=sr_1_...   I am using the same ThinkPad Pro Dock station as with my previous laptop. With my new T440 I am able to work with my laptop open or closed on the docking station with one external display plugged into the docking station. I am also able to work with one external display plugged directly into my laptop using the VGA to HDMI converter adapter.  ISSUE 2: The laptop will not recognize when both screens are plugged in at the same time, but they each work when I have only one plugged in either to the dock or directly to the laptop. PLEASE HELP!! TIA

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,
  Martin

A:Problem with Latitude E7440, E-series dock & external monitors

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:
http://www.dell.com/support/drivers/us/en/04/DriverDetails/Product/latitude-e5540-laptop?driverId=PTPX3&osCode=W764&fileId=3292828809&languageCode=en&categoryId=VI
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.

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!

We've been having screen issues when using a DisplayLink dock (specifically a Targus dock [ACP71USZ]).
There are two external monitors connected to it (making it 3x screens total). 
When connected the first time, all three screens work. But after a few minutes sometimes an hour, all three screens flicker and only the two external monitors work. When going to display settings, we only see the two external monitors. The laptop screen is not detected. When clicking detect, all three screens work again before flickering and returning to two external monitors only. When looking in the intel graphics GUI, nothing shows (until i repeat the process and press detect in display settings).
We tried installing to the latest intel drivers with no luck.
I ran the dell diagnostic tools multiple times (the preboot one and the desktop one) and saw no issues.
The older XPS 15 (9530) never has an issue.

A:Dell XPS 15 (9550) Screen Flickers and Blacks Out When Connected to DisplayLink Dock with External Monitors

 I am a little confused about the dock you mentioned. The specs for it say that it has 1 HDMI, 1 VGA, and 2 DVI ports, no DisplayLink.
