W540, Ultra Dock and 3840*2160

It took me some weeks to realize that the implementation of Nvidia is different from my W520 which was able to drive 3840*2160@30Hz natively through the built-in DP as well as the Dock's DP.
With the W540, I only get full Nvidia support (full means switching off Intel HD) when the W540 is connected to the dock. Before I buy a new dock (40A20135EU or 40A20170EU), I need to know whether the 4K resolution is working in this combination with my W540 with Nvidia Quattro 1100M.
With my w520 and ultra dock, the tech spec only mentioned resolutions up to 2560*1600 but 4K worked anyway at 30Hz with acceptable quality. Of course, I prefer to get 60Hz but with my Samsung 40' UHD and it's HDMi 2.0 interface I'm afraid that I will be stucked at 30Hz as there is no cable supportiing 60Hz with DP 1.2 output to an HDMI 2.0 input.
So; is anyone out there running the Ultra dock with W540 and 4K resolution successfully ?
Furthermore, like many others here in the forum, I experience the display switching off for some seconds randomly. I learned that running a 135W power supply could myke a difference, so I'm wondering wether buying the 0A20135EU 135W version is the better choice for my W540. I presume that the charging time will go up but are there other differences compared to the 170W version dock ?

I'm using a 4k screen in MST mode with the W540 and the ultra dock (170W power supply):
When using the dock in "normal mode" (= connected to the Intel chipset) the screen works - sort of. It will turn on and off quite a few times after plugging it in(Win 8.1) and then work for a few hours - at that point it switches off(you'll get some artifacts on screen warning you before it goes blank), which requires power-cycling screen and dock to get things working again.
If I set it to "advanced mode"(= connected to the NVidia chipset) the screen is detected but stays blank, presumably because the NVidia card doesn't like the "on-off" period. No 10-bit for me
If I plug the screen into the Thunderbolt port it works without any issues.
If anybody got things to work in "advanced mode", I would be interested as well...

W540 + Ultra docks = big serious issue

Hello everyone, We recently ordered 30+ x240s and w540 laptops using the ultradocks. Here's the prequel
1. initially they had the issue with monitors going blank, that has been fixed with a firmware update
2. there was a second firmware update ver 2.21 that fixes some issues with HP monitors. Ok , done.
Ok now all is well, we have the x240s on the docks and w540s with their docks + the 175w powersupply supplies etc.
Now we have users that wanted 27inch and some 30 inch monitors and a big big problem comes up.
The docks cannot drive anything higher then those 24inch monitors (1920x1200). the 27 inch (2560x1440) and the 30inch (2560x1600) does not work AT all.
it does not work with even ONE of those monitors hooked into the dock not speaking of the 2 that users wanted.
So w540+ultra dock + 1 27/30 inch monitor = nothing, blank screen, go to display settings and it detects a grey option
Now, the w540 without the ultra dock and hooked directly into a 27/30 inch monitor = no problem, we have full functionality.
We have tried every combination to try to get it to work and it's a no go.
Researched the dock's DVI port and see if we can possibly use that, nope, the DVI is only single link so our only option are the 2 display ports on the dock.
Of course those don't work at all. We have opened a ticket with lenovo and it's been escalated, awaiting responds.
This maybe a serious issue I am seeing here since we have 30+ docks and more coming. (yes we have tested on them all and their firmwares are 2.21)
Anyways, if anyone has run into this please confirm. Suggestions are welcome, but I am sure we have tried just about everything.
Thanks Everyone, J

I was able to connect a W540 to an Ultra Dock (170W) in "Standard" mode and then get an external monitor working at a resolution of 3840 x 2160. The monitor is a Samsung U28D590D connected via the DisplayPort on the docking station. Note that "Advanced" mode was very unstable, and often crashed within a few minutes. Standard mode works when connected via DisplayPort but would also crash instantly and repeatedly if connected via HDMI.
Tested with a variety of bios, firmware and driver versions. Including System BIOS v2.17 & v2.18. Docking station firmware v2.22 and multiple Intel and NVIDIA driver versions. None worked with HDMI or in Advanced mode. Hopefully this gets fixed at some point.

W540 + Ultra Dock on Linux

I have a W540 and it is running Ubuntu Linux (still going ever since the BIOS update). I want to get the docking station (the whole reason for buying a Lenovo) to have external keyboard mouse and monitor.
I am interested in the Ultra Dock:
http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...
I have read other posts about the Ultra Dock but the link to the compatibility chart is a dead link.
I see some of our T540 friends are having troubles with the Ultra Dock. It is not clear to me if those problems are also with the W540 models.
Has anyone with a W540 AND Linux been able to use the Ultra Dock with external monitors?

The keyboard and mouse seems to work fine with the dock. The dock behavior is quite inconsistent. My colleague has been able to project to two monitors and the screen by using Standard Mode (intel chip drives the dock outputs; in advanced mode nvidia drives the dock outputs) and then plugging one monitor into the vga output on the laptop, and the second monitor into the DVI output on the dock. He also has to do some weird unplugging and replugging ritual to get it all to work nice; it never works right on boot.
I am unable to replicate his success, however. He is even running on 12.04. I tried a bunch of things over the weekend: 12.04, 13.10, and even a daily build of 14.04 (which wouldn't even boot from the live cd). Right now I am running Linux Mint 16 (which is based on 13.10, I think). I would think a newer version would have more success. Another thing I notice is that when I open up restricted drivers, options to install the nvidia driver never shows up. However, doing an lspci | grep -i nvidia shows the nvidia driver, which means the system can see it (it even shows the model number: Quadro K1100M). It never shows up for me docked or undocked.
It's pretty disappointing because I would love to have two monitors. I think I can kind of make do with one monitor and the laptop screen for the time being, but it still sucks. What is frustrating also is that this laptop is supposed to be "Ubuntu certified", but in my experience it is anything but that.

X240 (Win 8.1) w/ Ultra Dock and two external monitors connected via DisplayPort problem

I'm having trouble making this combination work. This Ultra Dock does have two DP connectors, computer sees both external monitors (HP ZR24w) but I cannot get any picture on both at the same time using DP. Sometimes one display does work, but that is not always working.
When I connect same monitors via VGA/DSUB and DP (with Lenovo DPtoDVI converter) I can get this to work - both same time - , but I'd prefer them both digital and both native DP as both monitors do have that port.
Ultra Dock does already have the latest firmware and this problem seems to not relate to the flickering problem with T440 etc. X240 is also running latest UEFI/BIOS and I've also tried latest Intel Beta display driver, no effect.

W520 with Win 7 Pro
Minidock Plus Series 3
Two Asus monitors attached via DVI
Let me start by saying that the internal and both external monitors work simultaneously. However, getting to that state is the problem.
I can boot successfully with the laptop in the dock with 1) just the internal monitor, or 2) the internal and one external monitor connected.
However, if I try to boot with both monitors connected via DVI, the following happens:
Windows logon screen appears -- but there is no cursor on the screen
I enter the password and the login continues for 30-60 seconds, then
Blue screen SYSTEM_SERVICE_EXCEPTION for nvlddmkm.sys with STOP x0000003B
Lenovo has replaced the dock with no change in behavior.
Drivers and BIOS are current.
Most recent change was to set BIOS so Win 7 automatically detects Nvidia Optimus.
At this point, my best workaround is to disconnect one external monitor whenever I need to reboot, and then connect it again after everything is runing. Not terrible... but it really shouldn't be necessary. Any suggestions?
If you want to drive the monitors in the manner stated, the BIOS Display property must be set to Discrete and the auto detection below it must be disabled.

W540 170W Ultra Dock HDMI and windows 8.1

The W540 has an onboard video card in addition to the NVidia video card. We use AutoCAD and Revit, and will never care for the onboard video card driver. We cannot seem to get the 170 watt Ultra Docking Stations (plural) to work with our W540 Laptops (plural) when selecting the NVIDIA card and using an external monitor. We have updated all the drivers Lenovo has asked us to including the firmware on the docking station. We have followed the instructions to make the change in the BIOS so that the NVIDIA card is only used. We have called Lenovo support twice on two separate occasions. On one occasion, they said we are not the only people to call in about the problem, and that our only course of action is to get another docking station or return the dock to our vendor. Has anyone else had any luck using Windows 8.1, W540 on an ultra dock and using HDMI? Even though I mention HDMI, (because I think it is the main suspect), DVI seems to blue screen the laptop too.
Solved!
Go to Solution.

I'll give it a shot as nothing is working now. I'll post my findings.
I will say the limitation in the readme of the firmware update you sent me is important. It translates to I can't use the w540 with the ultra dock, AND use the nvidia card. As a consumer looking to purchase workstation class machines specifically to use the nvidia card, this doesn't sit right.
taken from the readme...
LIMITATION
- Some DP 1.2 monitors stay blank before operating systems bringing up.
- W540 discrete video mode will not work correctly with an external display.
- HDMI audio mute/unmute : unmute will take approximately 1 second.

Ultra dock + three external monitors not working

Hardware:
W540 + Ultra Dock (170W)
2x 24" LCDs @ 1920X1200 (DVI only)
1x 30" LCD @ 2560x1600 (DVI only)
1x Display Port to DVI Active Converter (for the 30" LCD)
What I want to have is four displays: W540 LCD + 3 external monitors as described above. However, I can only get two of the external displays to turn on regardless of how many chickens I sacrifice. Note: I've searched extensively to see if others have had this problem, which they obviously have, but none of the solutions worked.
I think the issue is the 'advanced' mode, but I already turned it on in the BIOS. The laptop LCD works correctly (2880x1620), the 30" LCD works correctly with the display port to DVI active adapter (2560x1600), and one of the 24" LCDs works correctly (1920x1200). However, the other 24" LCD isn't available in Windows as a detected display unless I start swapping cables, which will then enable it while disabling the other 24" LCD.
For reference, the connections are as follows:
Laptop LCD (built-in)
30" LCD: DisplayPort to DVI (active); Ultra Dock DisplayPort 0
24" LCD number 1: DisplayPort to DVI cable (passive); Ultra Dock DisplayPort 1
24" LCD number 2: DVI to DVI; Ultra Dock DVI Port 0
It's my understanding that the K1100M discrete graphics card should be driving all three of the external displays, but that isn't the case right now. I see one 24" and the 30" displays in the Nvidia Control Panel and I see all three working monitors (including the laptop LCD) in botht he Nvidia Control Panel and the Windows Display area.
Things I've tried:
Uninstalled + reinstalled Nvidia Quadro drivers
Uninstalled + reinstalled Intel 4600 drivers
Enabled Advanced mode in BIOS
Restarted 5,000 times
Swapped cables until my fingers started to bleed
Updated the firmware of the Ultra Dock (it was already fully updated)
According to this page, I should be able to connect six displays including the built-in LCD. When I first looked at it, I thought I could use both Ultra Dock DisplayPort ports as well as the Ultra Dock DVI port, but it's very unclear if that's actually the case. What does it mean by DP or HDMI and DP or DVI? Does that mean I can use both DisplayPorts (which I'm currently doing and it works) only? Does it mean I can use both DisplayPorts as well as HDMI and DVI? Does it mean if I want to use HDMI and DVI that I can't use either DisplayPort? Does it mean DVI and HDMI both share an output with one of the DisplayPorts so only one of each can be used at a time? TERRIBLE DOCUMENTATION.
Any help would be greatly appreciated as this has been extremely frustrating. I have a feeing the solution is going to be a disappointment as well because it's probably going to involve buying yet another adapter and/or using the Mini-DP output on the laptop instead of, you know, actually being able to use the expensive Ultra Dock...
[rant]
I have no idea how to tell if everything is working because the graphics card situation is extremely confusing. I didn't realize when I bought the laptop that the discrete card couldn't drive the laptop's built-in LCD, which is very annoying. Or, maybe that's not true, but the documentation is so confusing that I can't be sure either way. Also, and this really pissed me off, the Ultra Dock DVI connector can't drive a dual link display. What the hell??? Why was this not clearly annotated somewhere? I really hated needing to purchase a DisplayPort to DVI active adapter to make my brand new laptop dock work as advertised. UGH.

I'm struggling with a very similar problem. (Thinkpad W540, K2100, Ultradock 170W)
I am using 2 external monitors right now in bios display standard mode - it's the only way they work at all for me right now. I have tried uninstalling graphics drivers, enabling advanced mode, and restarting, but none of the external displays are detected. I've also tried updating the dock's firmware, but it doesn't seem to be updating (this may have already been updated).
Current working setup:
- 2 x 22" external LCDs connected to Ultradock via DP -> DVI cables
- Laptop integrated LCD
Related but not quite as equally frustrating, the integrated LCD does not resume when waking the computer from a sleep state. Only a reboot brings the display back.
I'd like to connect another 24" display over HDMI, but don't have any confidence of it working since advanced mode is utterly worthless for me at the moment. I'm quite dissatisfied especially since I purchased an extended warranty and last time I called for support Lenovo tried to sell me an additional support plan claiming that software was not covered under my current warranty.

Ultra Dock -- both DisplayPort monitors are always mirrored

I just got a new W550s with an Ultra Dock and it mostly works well with my setup -- Ubuntu 14.04 (Linux Mint 17.2). The problem I have is that both DP1 and DP2 are mirrored, and the Display utility only detects one screen. If I plug one of the monitors into the Mini-DP port on the laptop, it shows up as a third monitor and seems to work fine. Is there any way to use the two dock DisplayPort connectors as separate screens in Linux? Does this work properly in Windows at least? If so, at least there is some hope that we can make it work in Linux.

Betreff: T440s - Only 1024x768 on external monitor (DVI, Ultra Dock, Win8.1/Win7)

EDIT NOTE: This message was moved to the top of the thread in order to assist us with an escalation. For all future post and commments please continue posting in this thread.
One more victim here. T440s (fully patched, UltraDock, lid closed, external TrackPoint keyboard), Win8.1 (fully patched), HDMI, Acer T232HL touchscreen monitor.
Volcomtx85's posting (over 50% failure rate in a corporate setting) should warrant some attention.
Since there is a mix of Win7, Win8 and Win8.1 in the thread (presumably with different drivers), and different modes of monitor connectivity, the two points of commonality in the reports would seem to be BIOS and motherboard hardware. If so, let's hope it's the BIOS.
Solved!
Go to Solution.

Hello,
I have a T440s sitting in the Ultra Dock and a Samsung 2343bw hooked up by DVI.
On both Windows 8.1 and Windows 7 I can only set the resolution of the external screen to 1024x768. When I select a higher resolution, both internal and external monitor go black for a couple of seconds and when the desktop comes back it's still 1024x768 on the external monitor. I tried the following three drivers:
1) Deinstall display driver manually and let Win 8.1 pick a driver automatically, version 10.18.10.3318 (03-Oct-2013) gets installed. With this driver, both displays can be set to their native resolution. Unfortunately, the external display goes black once in a while and switches back on after 3 sec. The monitor itself is unlikely to be faulty, since it works well on my T400(+Dock).
2) Install driver from Lenovo driver matrix, you'll get 10.18.10.3282. With this driver, the external monitor only displays 1024x768 as described above.
3) Get the driver for HD 4400 from Intel website. It doesn't install voluntarily, but there is a workaround: http://www.intel.com/support/graphic...hd+4400+driver
I tried it and only get 1024x768 on the external display, just as with driver (2). If I connect the monitor by VGA, I get the blinking-error described in (1).
Hence, the external monitor is not usable, what is highly unsatisfying.
Can anyone confirm the Issue/problem? Is there a solution?
thanks,
niclas
PS:
- Bios of T440s is updated
- I installed the monitor driver from Samsung
- (1) is not an option in Win 7, only on Win8.1, since Win 7 doesn't find any driver for this card
- I am happy to provide further information when needed
- Edit: The screen works finde (DVI&VGA) on my T400 with dock.
- Edit: If I connect the screen via VGA, no

T440s + ThinkPad Ultra Dock after upgrade to Windows 10 - no signal

Hi, Yesterday I upgraded from Windows 8.1 to Windows 10 Enterprise. After the inital install I had both monitors working for a few minutes. Suddenly both monitors went in sleep mode and I'm unable to get them working. They are connected via 2 DP cables to a Ultra Dock station. Only way to get a signal (one at at time ) is to use a DP to mini-DP adapter and plug it directly to the computer. I can see that the computer is charging while docked, so there is some sort of connection there. I've searched all over the net for any drivers for the Ultra Dock and T440s which looks like can fix the the signal issue. No luck. Anyone else experienced this issue? Regards, hetterotte

Which Operator and Country SIM card you are using ?Error Code 36 is regular deactivation. Do a Windows update , Restart then Shut Down System and start ( TYhis Power cycles the Device ) . From your Screenshot it Looks like the Cellular Data is not ON and Microsoft cellular service is in some mismatched state after upgrade.After restart press like in below screenshot order 1 --> it turns cellular on or off, 2---> It will take you to settings page 3--> Connect from here. Dont ask why Microsoft made connecting to WWAN device so complex

A brand new W540 and the Ultra Dock humms, black out external screen, won't recognize mouse and some

Just received a W540 and an Ultra Dock. Here is my first impressions.
During setup ... tried to connect my speakers directly onto the laptop.... HUMMMMM! (really loud humming sound, until Windows loads ...sounds like a short somewhere ...). Ok, obviously sound is not the main focus of W540.
After a little while... boink! ... and the external screen goes black accompanied with the "Windows detected something disconnect"-sound. No matter what I clicked on the keyboard, or how much a moved the mouse, the external screen wouldn't turn on again. I had to flip up the screen on the laptop, and tada, Windows reported that something connected again, and the external screen turned on again. Turns out that I need to keep the laptop screen open at all times now, and now and then both screens disconnect and connect again. Not completely a showstopper, but somewhat annoying. Ok, how to fix - enter "lenovo ultra dock black screen" in Google and see that a bunch of people have experienced the same thing. After some reading, I found this official support page "LENOVO THINKPAD PRO DOCK AND THINKPAD ULTRA DOCK ARE CAUSING DISPLAY ISSUES ON EXTERNAL MONITORS" (http://support.lenovo.com/us/en/documents/ht081248). Seems to fit my situation perfectly. Just download the fwdphb03.exe program and follow the instructions. But does fwdphb03.exe even start?!? NO!
Just a brief flicker and no application nor instructions to follow. In addition, I am Administrator on my machine. Please make applications that at least attempt to work....
I have an Aten mouse and keyboard switch (KVM) (CS-1784 to be precise), which have been working seamlessly for years on all other machines I have (VMWare images with different Windows versions, Raspberry Pi and Mac). Connecting the KVM with it's mouse and keyboard renders a working keyboard and a dead mouse (remember - switching to one of the other machines renders working keyboard and mouse instantly).... <rant on>pheeew, starting to get a bad feeling here. OBVIOUSLY we have a lot of cool hardware like USB 3 and DisplayPort and what not, but WHAT DOES THAT MATTER, when the Lenovo folks can't program this stuff properly?</rant off>
The W540 comes with a lot of Lenovo software. Much of it is really good and useful. But what happened when you try to log in to Windows? For some reason Lenovo want to inform you that the Num Lock is on when you see the standard login screen. The message something like "Num Lock is on - your password may be entered incorrectly". All in some black background, covering OVER the login field in Windows !!!! Hey, the laptop has a numeric keyboard, I don't need this message. Luckily others again have experience the same thing. At this page http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/New-T540p-numlock-warning-at-login/td-p/142... I get the tip that I need to rename the tpnumlk.exe to something else. Gone was the stupid message.
My advice to Lenovo - don't include stuff that harvest a lot of complaints and that obviously is going to annoy your customers. Even if the machine was one with a small keyboard and no separate numeric keyboard, I would NEVER EVER want to have some ugly black box covering over the standard login field… I can’t even imagine that the developer of this tool, use it (nor like it)! That is exactly why bloatware gets its reputation.
I would of course understand all this if I were talking about cheap machines and some wacko docking station. But I am not.... This is state-of-the-art, 2014, expensive-style laptop from the same manufacturer.
PS! At the end of this session, Lenovo tells me that there is a problem with the powersystem, and that it want to reduce power to sustainable levels....

can you connect the device in _*recovery mode*_ ?

3 external monitors on W540 only connected to Ultra Dock

According to this document (http://download.lenovo.com/pccbbs/options/tp_ultra_dock_sp40a02135.pdf) it should be possible to attach 3 (three) external monitors/displays to a docked Thinkpad.
It should also work with 1 Display in the DisplayPort , a second one in the other DisplayPort and the 3rd monitor in the VGA port, is that correct? (So all monitors connected to the dock, not to the Thinkpad)
This should definitely be possible with a Thinkpad W540 right?
Is it possible to use daisy-chaining (DisplayPort 1.2 MST) to get MORE than 3 external monitors running?
You should also definitely update this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-76617 or add a new one for the new docks and thinkpads where one can easily find out how many monitors one can connect and how.

*Update*
I now have 4 monitors running on my 2009 17" mid-2009 MBP. The MBP, 2 17" Dell monitors and a 24" Dell monitor. Mavericks allows multiple displays as seperate working environments.
As you can see in the image (excuse the clutter..cable management is under the desk and its a WIP at the moment)I have the upper left monitor working in excel, the middle larger monitor in iTunes, the left monitor is browsing via Firefox and I'm in Safari in this forum on the MBP.
I have run Photoshop, Protools, Safari and Dreamweaver in this set up over the last few hours also.
The only issues I'm working through now is trying to have my dock on all displays and keeping the display setting after the MBP is put to sleep. Any suggestions are helpful.
At this time I haven't put the MBP in my Bookendz docking station, but I just updgraded to a 250GB Samsung SSD, 8GBRAM and replaced the superdrive with the old 500GB HDD. I also store most of my audio and graphic files on an external HDD and iCloud.

New docking stations Basic, Pro and Ultra Docks

Hi All,
Im new to these forums but wanted to see if any one else had had experience with the new docking stations. I just upgraded to a T440s which needed the new docking station... I had to get two of them for home and work. They are SO hard to put the PC in compared to the old series 3 docks for my old T410s... those things you did not even need to look when you put the PC down.. they just sliped in.. but the new ones, OMG each morning it takes me several tried to get them to dock.. I am thinking I am damaging the PC when I attempt to do this..
That being said, i am still a fan over EVERYTHING lenovo...
Any one else had similar experiences?
Tom

Hi All, I just received my T440s along with the new Ultra Dock. I have the T440s in the dock and connected to my TV used as monitor using HDMI cable. I hit f7 and can do "PC screen/extend/duplicate/2nd screen only, no problem. I chose the 2nd screen only for my work. Then I finished work and close the lid but when I come back to restart the laptop, I can only see the display on the laptop and no matter how I toggle using f7, I cannot display anything on my TV. The only way I can get back on track (2nd screen only mode) is to un-dock my laptop and hit f7 again. I never experienced this with my T410 using the older dock. Please help.

Ultra Dock 135W and 170W base identical?

Hi,
I am wondering if the base of both Ultra Docks is identical, and I can essentially convert 135W dock to a 170W dock by using a 170W adapter with it.
Thanks!
Solved!
Go to Solution.

Modify? There's nothing to modify.
The dock consists of two components, base and notebook charger. The notebook charger is absolutely standard, one of the same ones shipped with Lenovo laptops, same connector, everything.
The base seems the same for both docks to me. In fact, the updated firmware seems to be the same, too.
I just wanted to confirm if the base was indeed identical since 170W docks are nowhere to be found outside USA.

T450S in Lenovo ThinkPad Ultra Dock, network missing at startup

Network do not found when starting the laptop which is docked.
You need to unplug network cable from docking station and put back...that normally helps.
Without docking station the networks works well.
Also sometimes keyboard and mouse stops working (those are connected to docking station.

I am really sorry you are experiencing such issues. What makes me really mad is the fact, according to your words, that Lenovo support is directing you to this forum for help? This forum works on volunteer basis, so you might have a luck or not. I mean, you are living in the USA which is the most important market for Lenovo so if I would you, I would escallate the support issue.
Meanwhile, there are two options you might try out:
You could check if the firmware utility driver update helps, http://support.lenovo.com/us/en/documents/pd028011
or you might try out your luck with the native nVidia drivers, see http://us.download.nvidia.com/Windows/Quadro_Certified/334.95/334.95-quadro-notebook-win8-win7-64bit... .

Ultra Dock Warranty

I have a Ultra Dock 135w that I purchased second hand off ebay, it is still under warranty acording to http://support.lenovo.com/warrantylookup. It has the speaker buzzing problem and I tried to have it replaced but I am now being told I need proof of purchase. I checked the warranty terms and it says that this is required in some countries but not Australia.
Edit: I've been told that a photo with the base sticker in it is enough to determine the begin and end date of the warranty. So I don't have any complaints.

I'm struggling with a very similar problem. (Thinkpad W540, K2100, Ultradock 170W)
I am using 2 external monitors right now in bios display standard mode - it's the only way they work at all for me right now. I have tried uninstalling graphics drivers, enabling advanced mode, and restarting, but none of the external displays are detected. I've also tried updating the dock's firmware, but it doesn't seem to be updating (this may have already been updated).
Current working setup:
- 2 x 22" external LCDs connected to Ultradock via DP -> DVI cables
- Laptop integrated LCD
Related but not quite as equally frustrating, the integrated LCD does not resume when waking the computer from a sleep state. Only a reboot brings the display back.
I'd like to connect another 24" display over HDMI, but don't have any confidence of it working since advanced mode is utterly worthless for me at the moment. I'm quite dissatisfied especially since I purchased an extended warranty and last time I called for support Lenovo tried to sell me an additional support plan claiming that software was not covered under my current warranty.

W540, Ultra Dock and 3840*2160
