Thinkpad T480 with pro dock on 3 monitors

Q: Thinkpad T480 with pro dock on 3 monitors

Hi Guys,I have a T480 laptop with a pro dock docking station and 3 monitors i want to try to get working.2 of the monitors are working fine via a VGA > DP adapter. The 3rd i bought a USB-C to HDMI adapter, though i cannot get this to work, even with the other two monitors disconnected.If the laptops undocked and the 3rd monitor is connected to the USB-C port, it works. Has anyone had luck with 3 monitors on this docking station? I have been considering a display port hub, can we use adapters with these hubs ok or does it only work if the cable is solely DP Thanks guys

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 guys, I have a ThinkPad T480 combined with a Pro dock (side). I was hoping to use 3 external monitors (not including the laptop screen). The pro dock only has 2 display ports and the laptop has a HDMI port which i was hoping to all use to get my 3 displays.My setup is 2 VGA external monitors to display port adapters and 1 hdmi monitor to the laptops hdmi port directly. 2 display port monitors display fine, however the HDMI display goes black. If i un dock the laptop, the HDMI monitor works.Can i not output all 3 at the same time, i know the laptops chipset allows 3 monitors.I was thinking of buying a USB C to HDMI adapter for the 3rd monitor, maybe this would resolve it? thanks in advance

I have two 27" 2560x1440 60hz monitors that are plugged into the new Pro side-connect dock (40AH) with a new T480 (Intel 620 integrated graphics) in Windows 10 Pro. I can get either monitor to work fine with the dock individually, but trying to run both simultaneously by extending or duplicating the desktop between them seems to fail as selecting either option under Display Settings just makes the primary monitor black out for a few seconds then come back - the secondary monitor stays black.  There's no error msg or popup that would help me investigate further unfortunately. I'm trying this with the T480's lid closed, and I'm running the latest 1.14 BIOS update and latest Intel HD graphics drivers. This setup worked fine on my old OneLink dock and X1 Carbon previously, so I don't think it's an issue with the monitors themselves. Anyone have a similar setup with the new Pro dock that's working?

Hello,I've got brand new T480 with ThinkPad Hybrid USB-C with USB-A Dock and I'm experiencing USB issues when docked.I have read related topics and they seems to be dead without any working solution. Description of problem:When I docked my T480 for the first time, all USBs (only mouse and keyboard) were working. I had left office for night and when I have returned and docked my laptop again, USBs seems to stop working. I?ve tried to reconnecting dock, powering dock off and unplugging devices or changing USB slots without any success.Only restart of computer seemed to get USBs working back again. BUT, there have been about 5 minute period when USB devices were randomly connecting and disconnecting without any warning.Problem appeared again when I left my desk for 30 minutes without turning off or putting laptop into sleep. USBs were dead again. Only restart helped and it was followed with 5 minute period of randomly disconnecting USB devices again.All other connected devices ? 1x FHD monitor via DP, 1x FHD monitor via HDMI and headphones via front 3.5mm jack are working without any problems and laptop is charging properly as well. My laptop is fully updated via Lenovo Vantage and dock in currently at only available FW. Is there any solution to this? It?s get pretty annoying for laptop that is meant to be docked! And it seems that problem occurs accros multiple ThinkPad Thunderbolt docks.. Thank you

 I have been using a Lenovo T430s for a few years, and docking to 3 external monitors. After many initial setup difficulties, this works well but the system can only handle 1920 x 1080. Also, I miss the smaller size of my X201. Can someone please explain the multiple monitor possibilities for the latest X series Thinkpads? Ideally, I would like to run 3 (not just 2) at a higher resolution than 1920 x 1080. However, it would also be interesting to know if I might run only 2, but at 4k? Or only 2, but two of the new Samsung ultrawide gaming monitors? Thanks for ideas.

I have a Pro dock that I realize can only drive 1 digital signal with so I am using the DVI port to display to 1 external monitor and the LCD itself. I am trying to connect a second monitor using the mini DisplayPort  on the right side of the laptop, but Windows 10 does not detect this monitor to be available. If I disconnect the DVI cable on the back of the dock, I get output on the mini DisplayPort.

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.

Hi, Can somebody please confim if the ThinkPad Workstation Dock 230W will power 2 x 2560x1440 monitors @ 60Hz? When I look at this link ThinkPad Workstation Dock 230W it onlyy talks about 3840x2160 and 1920x1200. I suspect if it is purely passing through 1 x 1.2 DisplayPort that it will indeed work but I see nothing to confirm this anywhere. Thank you in advance! Jonathan.

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?

Hello everyone, I recently bought a Thinkpad X1 Extreme and I am now locking for a suitable Thunderbolt 3 dock. Although I've read a lot of posts about various docks I am still a little consfused about which one to choose. It seems like the following ones would all work with the X1 Extreme:1. Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W:https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...2. ThinkPad Thunderbolt 3 Workstation Dock (170W):https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...3.

Or are there any other technical differences? So if I am okay with a two cable solution couldn't I just use the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W and connect it via Thunderbolt while at the same time use my 135W AC adapter to charge the laptop? Thanks a lot in advance.

I have a user with two LT3053s (2560 x 1600) and his previous T440 + Ultra Dock (I believe) supported the full resolution at 60 Hz (again I believe).  I upgraded him to a T480 and our standard Type-c dock that we deploy limited the screens to 1920x1080 @ 60Hz.  After this and complaints from the user of headaches from the drop in resolution we purchased a TB3 Gen 2 Dock and even after plugging the dock in to the actual TB3 port on the laptop (not the top type-c port) we are having issues with not all of his devices working, namely the kb+m. Any ideas here?  Right now we are running it with the 135W power adapter that it came with, but there is also another power adapter available that did not come with the unit we purchased.

Hi, I'm using a Thinkpad Pro dock with an L470 on Windows 10(both brand new). I have a VGA monitor and a DVI monitor connected, and I can output to both screens as well as the laptop display just fine, however as soon as I undock, or switch off the laptop, when I come to use it again, neither of the screens are showing as connected. I have to unplug them from the dock and plug them back in again, at which point they are recognised and work fine... until next time I have to undock/switch off. I have tried this with a different laptop (also L470, but running windows 8.1) with even worse results. On 8.1 the screen will repeatedly flicker for about 10 seconds, and any combination of the screens will work (sometimes just the laptop screen, sometimes just 1 monitor, sometimes all 3). Even when all 3 work, it rarely has the correct resolution, and takes several attempts to get it working properly. The whole point of having a dock is that there is no need to keep plugging things in every time you sit down, if I have to re-plug the monitors every time it is pretty pointless having a dock in the first place. I have updated the BIOS on the laptop, updated every driver, updated the firmware for the dock and Windows 10 is bang up to date. I'm about out of ideas now and was wondering if anyone had any ideas on a fix for this? I see web searches that this is quite a common issue, but most of the "fixes" are what I have already done, or are specific to Windows 7 or 8... Read more

We are currently using Lenovo T480 laptops with ThinkPad Thunderbolt 3 Docks (Model 40AC0135US) in our office and frequently encounter the following issues: ? When a user connects their T480 to the dock, their monitors do not display any video? When a user connects their T480 to their dock, their monitors will display video, but USB peripherals (keyboard, mouse) do not work? When disconnecting from a dock, the charging light on the T480 stays lit and Windows shows the laptop is still connected to power and charging? External displays flicker intermittently When a user experience issues with their dock, the only way to get things working again is to shut down the computer, disable the internal battery in the BIOS, and then plug the T480 into the dock and turn it on. However, the issue eventually returns and we have to repeat the steps again. We have also tried the following steps, but continue to see issues:? Run Lenovo System Update and install all driver, bios, and dock firmware updates? Replaced Thunderbolt cable? Change the Thunderbolt Security Level in bios to No Security and Uninstall Thunderbolt Software Most of our laptops are running Windows 10 1709. Has anyone else experienced these issues and know of a good solution?

I own a Thinkpad T480 (20L5: Intel UHD graphics, Core i5 8th gen) and since it supports Thunderbolt 3, I want to attach an external GPU and display for light gaming. I see that Lenovo itself has a "Lenovo Thunderbolt Graphics Dock" but does not offer that as compatible with the Thinkpad series. Nevertheless, as Thunderbolt 3 is a standard, I am wondering if the Graphics Dock works with the T480. Did anybody already try that?

Hi I cant seem to locate a fix for my lenovo t480. I cannot get any usb ports to register through the dock. I have tried reinstalling usb drivers through device manger, updating dock firmware, updating all lenovo system drivers , changing power adaptor through the dock and re seating it multiple times. I have other t480's that work on this dock. The usb's work fine on the actual laptop just not the dock. Any help would be apreciated. Thank you!

I have a new T480 and Lenovo Thunderbolt 3 dock. I find that often when I close--but in no way shut down--the computer for the night, when I restart in the morning, it completely restarts, so I lose open tabs, unsaved work, etc. I can understand enough of the system event log to determine that the computer always goes to sleep when I close it, then, per the power plan, hibernates three hours later--or at least tries to. The first sign of trouble in the logs comes at the time of hibernation. For example, at 2:37:25 this morning there is the routine Information event, "The system is entering sleep. Sleep Reason: Hibernate from Sleep - Fixed Timeout." This is followed immediately by the warning, "6105 - deauth after EAPOL key exchange sequence". Over the next 5 minutes come two more warnings and eight errors. Then nothing until I start the machine in the morning. One of the first events on restart is the information message, "The last shutdown's success status was false. The last boot's success status was true." It appears to me that this only happens if the computer is plugged into the Thunderbolt 3 dock overnight. To the dock are connected a (gigabit) ethernet cable, a displayport monitor, a mouse, a keyboard, and a pair of headphones. Here is a fuller dump of the error log at the last time it was hibernating, or trying to: Level Date and Time Source Event ID Task CategoryError 7/30/2018 2:41:33 AM Microsoft-Windows-DistributedCOM 10010 None The server {3EB...

Mates, has anyone been able to successfully use a TB3 Gen 2 (40AN) with a T480 (20L6)? I'm looking to run dual 4k monitors at 60Hz over the DP connections. If they are not compatible, it appears I can use the TB3 (40AC) with the T480 using DP1 and TB downstream to drive both at 4k 60Hz, correct? Many thanks for all help in advance!
