T480 with Ultra Dock External Monitor Blinking

Q: T480 with Ultra Dock External Monitor Blinking

I have a T480 with Windows 10 Pro connected to a Dell U3415W monitor via a DisplayPort to HDMI cable via a 40AJ0135US Ultra Dock (DisplayPort side connected to the docking station, HDMI connected to the monitor). While using this setup, I will occasionally (sometimes quite frequently) get black-outs in the monitor for a few seconds and then the display returns without issue. Its extremely annoying and interrupts my work. Often, restarting the laptop will help resolve it for a while but it always returns in some fashion. I have run the ThinkPad Docking Station FW updater and it said everything is up to date. Additionally, Lenovo System Update is 100% updated. Any suggestions would be greatly appreciated.

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.

System is a Latitude E5570 in E-Port Plus II dock, connected to two Dell U2515H monitors via Display Port.
Primary monitor blanks regularly for 2-3 seconds, but secondary mirror does not.
I have followed all instructions in this knowledgebase article: www.dell.com/.../blanking--flickering-or-blinking-video-issues-on-external-monitor-for-dell-latitude-exx70-exx40--precision-xx10-systems
Unfortunately, no remedy yet.
All graphics drivers are up to date, based on offered driver downloads for my system.
A Latitude E6530 does not show this issue when docked in the same dock with the monitor configuration unchanged. The monitor only blinks when E5570 is in dock. Blinking is irregular, sometimes a few times a minute, sometimes every few minutes, sometimes only each hour.
Changed Display Port cable to primary monitor, did not help.
Monitors are not daisy chained, but connected individually to dock to allow older systems to dock.
Would appreciate any advice.
Thanks!

A:Unresolved 2-3s blinking of external monitor at Dell E-Port Plus II Dock

We had this issue and it was resolved by a firmware update to the MST hub built into the system.  Go to support.dell.com, select your system, select Drivers and Downloads, and search "MST".  Note that sometimes if the OS selected by default there is the one you want, you have to choose some other OS and then switch back for anything to appear.  Anyway, the update you're looking for is Synaptics-VMM3320-MST-HUB-Firmware-Updater_DJG3X_WIN_3.12.1_A03.EXE.  I'd post a link, but most of the time that causes posts to get stuck in moderator queues.  Note that when you run the update, you have to have the system docked with an external display connected and in use, and then restart afterward.

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 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!

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

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

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.)

Fixed; was a driver issue. Problem seems exclusive to a Dell u2415 on DP port 1 only of the dock or to the laptop's DP port (at least for the couple monitors I tried). It's possible it could affect other monitors. My starting point: 9.18.13.4535 / 9.17.10.2843 (Nvidia /  Intel) The latest driver from Lenovo is 9.18.13.4535 / 8.15.10.2725. I'm not sure how i have a slightly newer Intel, but that's what it was. I couldn't install the Lenovo driver. I also couldn't install a newer driver from Intel (10.18.10.4276). In both cases Windows or the Intel installer stopped me saying the mfr provided the drivers and that the installed version was up to date. I worked around by first rolling back the Intel driver. The manual (.zip) install of the latest intel driver worked. This immediately fixed the Dell u2415 on DP port 1 and laptop's built-in DP port.

No matter what I do however the external monitor will start blinking. It will turn black for a second and then go back as usual. At times the blinking is so frequent that you cannot see anything.

Tried different HDMI cables (3 to be exact) but no luck.

I also went into the NVIDIA control panel and from the 3D settings I chose the Integrated Graphics as the Preferred Graphics Processor. (only made an exception for WoW to use the NVIDIA processor)

I have spent hours upon hours online trying to find a solution but to no avail. Any help will be more than greatly appreciated.

A:Connecting external monitor to USB-C Dock

Hi, I think it has DisplayLink sticker or DisplayLink Certified that means you can connect 2 monitors at the same time. It has DP port (6) and HDMI port (5) and you can use both             Side note: From your image, the dock price is US$149.00 + tax (says 7.5%) = around AU$210 but HP in Australia sells for AU$329              Amazing ! AU$100 more for HP Australia for a same product. May be HP has to ship the product from China to the US first then send first class air to Australia. Regards.

The dock is connected to an external monitor via DisplayPort cable and displays at the same quad HD resolution as the laptop display.  The problem I'm having is that when I plug the laptop into the dock and the external monitor goes on, the display is occasionally jittery for a while. Every few seconds it will jitter. Then it settles down after a while, maybe half an hour to an hour. Any ideas as to what's wrong? Is this a problem with the display adapter in the laptop? Thanks, - bill.

hi, I have setup one of my faculty with a Yoga 920131KB plus Thunderbolt 3 Dock. He has an existing monitor (Samsung Syncmaster P2450) that should support 1920x1080. Seems to be current on all drivers and patches under Win10 EDU version. (Including the CCG4 Firmware Update to v55). We are using the HDMI output from the dock. If we try to configure extended desktop to the Samsung monitor at 1920x1080, the screen extends off both sides about half an inch. Maybe also a quarter inch over at the top.  As a work-around, set at 1680x1050, video generally works as expected, but the display starts about 2" in from either side. Generally I don't like using add-on utilities (prefer to just use standard windows built-in options), but somewhere along the line this has the Intel Graphics HD Utility.  I was using that to switch resolution, the Windows settings seemed to track along with changes in the Intel utility, but still overscanned the display.  I played with some other settings in the utility about Display Scale (other than 100%), didn't seem to change anything. A second problem occurs with this setup: when the laptop is used at home, put to sleep, then plugged into the dock, the screen is displayed on the external monitor at maybe 200% (?).  That is, you only see the central portion of the image.  No fiddling with settings seems to correct it, but rebooting usually fixes it. The second problem also occurs with a similar Yoga 920 + Dock (d...

Also wanted to mention something I noticed while working on this: I saved a log from the Intel Utility. There is a section in there about "Maximum Image Size". This seemed to be correct for the laptop display (12.2"x6.69") but the Samsung was listed at 6.3" x 3.54"    It is a 24" diagonal display, so that is obviously wrong, but I don't know that it is important. Intel(R) UHD Graphics 620 Report Date: Monday, February 5, 2018Report Time [hh:mm:ss]: 1:21:19 PMDriver Version: 23.20.16.4849Operating System: Windows* 10 Education (10.0.16299)Physical Memory: 16225 MBVendor ID: 8086Device ID: 5917Device Revision: 07Graphics Output Protocol (GOP) Version: 9.0.1066Current Resolution: 1680 x 1050 Display Type: DigitalDDC2 Protocol: SupportedGamma: 2.2Connector Type: DisplayPortDevice Type: DisplayPortMaximum Image SizeHorizontal Size: 6.3 inchesVertical Size: 3.54 inches

I thought there would be a selection for this somewhere but I've searched and can't find it, so sorry if a solution is obvious! Got a T470 and Ultra dock (not the USB one) with an external monitor connected via DVI and left in standby. I want to boot on the laptop only, and then I can extend to the external screen as needed.  Is this possible?  I was using a T61 in a dock before (with Windows10) and that defaulted to the laptop screen.

Hey Forum, Netflix refuses to recognize my external monitor as 4k capable. The 4K monitor is connected via the displayport on a Thunderbolt 3 dock that's connected to my X1Y3. The same monitor was recognized as 4K capable when it's connected to my desktop. Anything I need to change to make streaming 4K possible? Thanks a lot for your help! Jack

I know this is a common problem, but so far I did not find a solution to it.  The external monitors connected to my prodock via VGA and DVI blacks out every few seconds, especially during heavy usage. At first, I thought it was a power supply issue so I bought a 90W supply. Now the monitors stays on most of the time, but still blacks out every 10 minutes or so, even during standby with minimal power usage. Then I tried editing the integrated graphics settings, updating/rolling back graphics driver, flashing the docking station firmware with every version I can find, and switching to ubuntu on the other drive, but there wasn't a single combination of settings which would keep the external monitor on for more than an hour without blacking out/disconnecting.  So what should I do now?  System info:i7 5600u, 12G RAM, 16G + 128G ssd, 500G hdd, NO 940M, FHD IPS nontouch screen, Windows 10/Ubuntu 16.04Thinkpad Prodock 04A1, 45W/90W power supply. All USB and audio ports works perfectly. Both monitors are 1440x900 at 60Hz, works flawlessly when attached to laptop VGA port.

Just received a new X1 Yoga 2nd gen laptop with a USB-C dock (40A90090US) and I'm trying to run a three monitor setup.  Tried with the two built in display port connections and the laptop screen, but that's not working.  Currently have it running with one display port, the laptop screen, and the HDMI port on the laptop, but that's not ideal, having to plug in two cables.  I'd prefer to not use the VGA port, but would that be the only way to have two active external monitors coming from the dock in addition to the laptop screen?  Other option is that I could probably scrounge a third monitor, leave the laptop closed and run three monitors off the dock, though as near as I can tell, that dock doesn't support three live monitors.  Looks like I'd need to upgrade to the thunderbolt dock (40AC0135xx) for that to work, is that correct? Thanks for any input...

Hi, I own an EliteBook 8770w with docking station A7E32AA. I'd like to connect a ultra-widescreen external monitor (3440 x 1440). I was not able to find information whether such monitor can be connected to this laptop (via DisplayPort or DVI) using full resolution. Graphics chip AMD FirePro M4000 supports 4k resolution according to the specs. Does anyone have any experience with a simular setup? Thanks, Matej

Hi dougdykman
 
Can you please specify your full Thinkpad model number and the model of OneLink dock that you are using.
Some Thinkpad and some OneLink dock models has some firmware (BIOS) update to improve compatibility.

Hi,
I just received the TB16 dock, using with a Precision 5520 with Ubuntu and an P2415Q external monitor, and am happy with them, except for one regression.
In the past I've adjusted the brightness of the monitor with a command-line program that talks DDC over I2C and it works great changing brightness between morning, afternoon, and night modes.
I purchased the TB16 for the main purpose of providing a single cable connection to everything. But, when I connect the external monitor to the dock the DDC command signals are blocked (or not relayed). In short, I need a second cable to control the monitor.
This defeats the main purpose of the dock, and it is quite expensive for the other features, I certainly could spend less than $300 on a second power supply and usb hub. :-(
The question is then, is anyone aware of this problem, is it possible to be solved, and will it at some point in the future?
Thanks.

Hallo, ich habe seit einiger Zeit das Problem, dass der externe Monitor, der per DP an den Pro Dock und zum T460s angeschlossen ist, sporadische Aussetzer hat.
