I'm using a T430s and a mini dock plus series 3. This is the dock with the dual DVI, dual DisplayPort, 1x VGA. I do not use the laptop's built-in screen; just the 2 external monitors. Intel HD4000 graphic chip and Nvidia Optimus/ I previously had 2 20" monitors with a 1680x1050 resolution using DVI-to-DVI. They both worked fine. I upgraded to 2 24" monitors with a 1920x1200 resolution. The laptop is not recognizing the second monitor. I have tried:dual display port (dock side) to mini display port (monitor side): only 1 monitor recognizeddual dvi (dock side) to HDMI (monitor side): only 1 monitor recognizedI ruled out monitor and cable problems by swapping...each by itself works fine. Looking up specs, I believe this resolution should be supported by DP or DVI. Can anybody confirm that this is a supported config? Any ideas what is wrong? UPDATE - I did try 1 DP/mDP and 1 DVI/HDMI: this does work. However, its not an ideal solution because it would interfere with the monitors ports which I want to use for a second PC. UPDATE 2 - OK, now I am beyond aggrivated. I also have a support ticket w/ Lenovo where they suggested switching to Integrated Graphics only in the BIOS. I tried that, no luck. After changing that setting back, i tried to get my 1 DP / 1 DVI working, but now it would not recognize dual monitors. ??? After some testing, I'm finding that the -only- setup that works is the following: Dock DVI port 1 to Moni...

A:Second monitor not detected: T430s with Mini Dock Plus Series 3 dual external monitor

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.

Have been happily running windows 10 - with dual monitors, but since a recent update, the system once re-docked will no longer re-detect that it using different monitors. Previously i could use it:1. Un-docked - at 1600 x 9002. then when i put it to sleep3. 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? Or is this a "consequence of doing things in a certain order" System:Lenovo T430s laptop -HD Graphics 4000  version 10.18.10.4425 (from Lenovo System Update)UPDATED: to 10.18.10.4653 - 7/4/2017with a Lenovo ThnikPad Usb 3.0 Pro Dock (dual HDMI/DVI ports)dual BenQ GL2450 monitors.

I have a T430s with the NVIDA graphics card and the Mini Dock 3.  My monitor is old, and I was going to buy a new one.  However I won a 24 inch Vizio TV at a work raffle and since it's too small to use for a regular TV I thought it might make a good monitor.  I have the HDMI adapters that came with the dock. Would there be any technical issues that I should be aware of or that would present a problem(s)? Thanks for any/all help!!! GBA

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?

Hi I have a W520 with NVidia Quadro 2000M and 2 x Dell U2515H monitors. The Dell user guide says to enable DP 1.2 which I have done on both monitors. I have the W520 on a Mini Dock 4338 and monitor 1 is connected to that via a DisplayPort cable. On monitor 1 I then have a DP cable in the Out port going in to monitor 2 via the In port. My problem is that I can only get a duplicate display on both Dell monitors. When I use the NVidia control panel (version 8.1.870.0) & try to set up multiple monitors it only shows one monitor. I looked in Personalization and click on Detect it shows both Dells as monitor 1. I want to extend the displays. Any help appreciated.

Hello Everyone, This Forum was very helpful when I was setting up a docking station for 3 external monitors - thank you. In the end, the T430s continues to work well, where using the DisplayPort outputs (+ VGA?) on my docking station, I can get 3 external monitors to run at 1920 x 1080. I am now interested in higher resolution, however - at least 2560 x 1440 or if possible, 4K.  (My understanding is that higher than 1920 x 1080 will limit me to 2 external monitors vs 3 but that's OK.) Here is where I need help: Using 28" Samsung 4K monitors, I am able to drive 2 external monitors at 2560 x 1440, using 2 DisplayPorts (on dock) to DisplayPort connections on the monitors. Experimenting with a bigger, 55" 4K screen however does not work : ( Becauser the bigger screen has only HDMI and no DisplayPort.    (I tried a DisplayPort to HDMI adapter, but it did not work either - apparently the adapter constrains the display to 1920 x 1080)  Can anyone please help?  Is there an active DisplayPort to HDMI adapter that will pass 2560 x 1440 or higher? Can I somehow use the DVI ports on the dock to drive 2560 x 1440?  Could the new X1 with a 2560 x 1440 native resolution do a better job? In summary, 1) I want to use at least 2 and possibly 3, 55" 4K screens, which have HDMI inputs only 2) Display at least 2560 x 1440 - hopefully with future ability to 4K 3) Would rathe...

A:T430s / Nvidia - Higher Resolution than 1920 x 1080? With 2-3 External Monitors and HDMI

your external monitor requires HDMI 1.4 port to drive the 4K resolution, as far as i know there is no Displayport to HDMI 1.4 converter on the market. The DVI ports on the dock is single link only, so it can't drive the 2560x1440 resolution you require. The new X1 Carbon Gen 2 has HDMI 1.4 and can drive the screen at 4K. But it has only one HDMI 1.4 port, so you are limited to driving one 4K LCD at this resolution.

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.

I recently got a Thinklpad P1 from my company for work, together with a Thunderbolt 3 dock. The installed OS is Ubuntu Linux 18.10 (standard flavour, with Gnome). When I set the graphics to "Hybrid" in the Bios, the 2 external displays plugged in the dock are not detected. Network and USB work fine. When I switch to "Discrete", both monitor are detected and work fine. It's annoying, because the laptop heats up more, the fan runs almost all the time and if I use the laptop unplugged the battery is drained much faster, unless I switch temporarily back to Hybrid. I'm grateful for any help!

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,

HP Zbook Studio G3 connected to two ASUS 24" HDMI screens (VE248H with different firmware) via the HP Tunderbolt Dock 3.  Screens are connected via Displayport to HDMI adapters. Upon boot up, one of the screens does not sync- which one is random. If it is the primary screen, the symptom is a loop of the screen blacking out ever 3 seconds or so for 2 seconds then lighting up again. Sometimes this is accompanied with an audible click. If it is the secondary screen the loop is the image wobbles every 5 seconds or so, blacks out briefly then comes back on.  I have updated the firmware on the dock, the BIOS, and all the drivers.  The daily steps to resolve the problem involve the Multiple displays option in Window's Screen Resolution. By changing it back and forth between the individual displays and the "Extend these displays" option I eventually get the screens to stabilize. Any help would be nice. Wasting 5 - 10 minutes each morning on this is frustrating.

Hi all,
Currently running a Latitude 5480 through a WD15 Dock. I have two monitors but can't get both to display. The dock itself has a number of connection options however it doesn't have two VGA ports. If I connect one of the monitors to the VGA port that works ok. If I use an adapter on the other VGA monitor to plug into the HDMI port on the dock it doesn't detect it on the Latitude.
Anybody successfully managed to get two VGA monitors to connect using the WD15, and if so how did you manage it?

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

So, I have a following HW:- ThinkPad T560- ThinkPad Pro Dock 90W (40A10090EU)- 2 external identical monitors (Eizo EV2436W) Currently I am trying to use 3 screens:1. internal on the laptop with resolution 1920x1080 @ 60Hz2. external monitor connected to Pro Dock using DisplayPort with resolution 1920x1200 @ 60Hz3. external monitor connected to Pro Dock using VGA with resolution 1920x1200 @ 60Hz Internal display is okay, unfortunately for the external displays, I can set 1920x1200 only on 1 external monitor by default & 1920x1080 for the other one. When I use tool from Intel for managing the displays, I am able to set the custom resolution for the 2nd monitor to 1920x1200 but the image is blurry (I bet you to come and try to look at it at for 5 minutes). 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!

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!

A:HP Spectre with travel dock and two external monitors?

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.

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!

i tried to connect one dell monitor to mini dp and another to a USB-VGA display adapter. I can only get the mini dp connected monitor to work. The USB-VGA will not work. I've been using this exact same setup with the X230 for years without problem. Does anyone know what i might have done wrong ? Thanks

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'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'm hoping I can get this resolved on this forum.I just got my system and am trying to connect my 3 external monitors.    My setup is as follows:Monitor 1 - laptop screen - works.Monitor 2 - HDMI out to HDMI in - worksMonitor 3 - DP out to HDMI in via a DP-HDMI cable.  - worksMonitor 4 - DP ou to DVI in via a DP-DVI adapter - doesn't work.

Incidentally in this configuration, when I closed the laptop screen this monitor worked.  Also on a related note, the Nvidia Quadro P500  is sitting idle as the Intel UHD 620 is doing all the work.  How can I control this? Thanks for any suggestions. Sal

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.

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.

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!

Do you guys have the same issue ? or anyone already solved it ?

(The TechCenter asked me to use mDP and DP instead of using mDP and HDMI, the issue remains the same fyi whatever the combo between mDP, DP and HDMI)
