Q: Issues with Thunderbolt and external displays on T480s

Hi everyone!I recently purchased a T480s with the following specs:- i7 8550u- MX150 Graphics- 16GB of RAM- WQHD Display I am running a Setup with the following Displays: internal Display @ WQHD, external Display 1 @ WQHD, external Display 2 @ FHD.Everything works perfectly fine, if I connect External Display 1 via a Thunderbolt Dock and DisplayPort and External Display 2 via HDMI directly. The problem I encounter is the following:I have some "small Adapters" for Thunderbolt -> HDMI or Display Port. They used to work fine until yesterday, now all adapters, except for one (USB C -> HDMI, USB and USB-C) have stopped working. All I get is a message stating that there is a malfunctioning USB device.Funny part: All adapters work fine on a Dell XPS15, Lenovo MIIX 510 Tab, and so on. Whats the problem? I already tried System Restore to a few days ago, did not help... Thanks,Jakob

Hello, I have a Lenovo T480S running Linux and am trying to connect two external monitors without the use of a doc station. Since I cannot use both HDMI and USB-C ports at the same time as described in the documentation: https://download.lenovo.com/pccbbs/pubs/t480s/html_en/index_en.html#Using_an_external_display_(topic... I connected as following : The first display is connected via HDMI to the HDMI port and is working without any problems. The second display is connected to the  the USB-C (Thunderbolt 3 compatible) port, using an USB-C to HDMI cable like this one: https://www.amazon.com/gp/product/B075V5JK36/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1  But the second monitor does not work, even with the HDMI port not in use. Any pointers on how to connect two displays at the same time to the T480S without a doc ? Is that even supported ? Thanks and best regards,MMV.

Hi, I am looking to buy a t480, t480s or X1 carbon, I am now deciding which one to get. I was hoping to use the laptop with 2 asus MB16AC USB screens, so a screen that takes power from the USB-C port and uses DisplayPort? Alt Mode for USB Type-C? to connect to the display without any drivers. Would this work on the X1 if I use the 2 Thunderbolt ports?Would this work on the t480/t480s if I use the Thunderbolt port and USB-C / Charging port? I know the screen can install a displaylink driver if it's can't connect through DisplayPort? Alt Mode for USB Type-C?, but I don't want to use the driver,m I only want to connect through the native connection.Thanks!Gianni

Hi, I have a HP Elitebook Folio 1020 G1 for about 6 months now. I have purchased the HP docking station and now trying to work with two monitors. One connected with VGA and another one connected with DVI.

I have two Samsung UE510 28" 4K Displays that I want to use as eternal monitors on my Lenovo w550s laptop. I have one mini display port that should support them. The display adapter is an Intel HD Graphics 5500 with NVIDIA Quadro K620M. From what I can tell I should be able to use a dual video adapter to out of the port into the monitors. The monitors are currently hooked up via Displayport cables. The problem is that I can only get one monitor to display content and the other one just keeps flashing like it is detecting then not. I have updated all drivers but nothing is working. Any Help would be appreciated. Thanks

I am trying to use a 3rd party external GPU enclosure that attaches via thunderbolt, and when attached, I got the message pop-up that external GPU support was not enabled by the vendor, and as such the device will likely not work? Has Dell locked the Latitude 7480 down to no external GPU support?

Probably.  I read somewhere that since Dell is pushing their Alienware external GPU stuff that uses a proprietary connection, they never enabled external GPU support via Thunderbolt.

Hello,

I am looking for help, as I have been having some resolution issues with my extended monitors for quite some time.  There are a large number of problems that range from BSODing shortly after re-connecting my docked monitors on a regular basis to having constant annoyances with sizes on screen.  I have tried and searched for hours and attempted every applicable resolution, but I haven't found a correct solution.  While I would love to resolve problems with resolution, the BSODs after re-docking are my primary problem.
Problems

Refer to this gallery for images citing the specific resolution issues (apologies for the compressed/poor quality):  http://imgur.com/a/JP1te
BSOD after re-connecting my laptop to either docks (takes about 15-20 minutes and gives multiple error messages)
Very inconsistent font sizes and sizes associated with Windows and file explorer
Applications, both DPI-aware and non-DPI aware, have scaling issues

Things I have tried/notice:

Updated drivers, BIOS, firmware, software, etc.
Ran the various Windows commands to check for errors (sfc /scannow, dism, etc.)
Swapped wires and re-seated connections
Adjusted refresh rate on external monitors to 59 and 60 hz
Adjusted resolution on primary monitor to 1920x1080 to match both external monitors (while this is an undesirable solution, it did help some problems and helped address many of the sizing problems, especially with file explorer)

Additionally, often if my computer goes from Lock Screen -> monitor off following an idle time, the monitor will not "wake up" or render to a usable state.  I have attempted to wait, push buttons, close the lid, re-connect/disconnect monitors, etc.  The only solution is to perform a hard reboot.

It's not clear to me what 'Wake by Thunderbolt' (hereafter WbT) does and whether or not it's required for 'Wake On LAN' (hereafter WOL).  In the T470s and T480s user guides, there's no mention that WbT is required for WOL so I'm thinking it's not.  But then again, since Ethernet is in the dock itself, and seeing how there are controls for PXE, I could see how it might be required. ReferencesT470s User GuideT480s User Guide

I'm trying to setup three external screens configuration and stumbled upon the following. I have 3 screens: 1. 4k (3840x2160) 60Hz2. 2560x1600 60Hz3. 1920x1200 60Hz I was hoping to use all possible outputs on the laptop (2 USB-C and HDMI), but apparently you can't do that - you can pick only two out of those three. I also tried using USB-C docking station, and again - it limits resolution to 1200p, which is not enough (4K display via USB-C, docking station via second USB-C and two screens 1200p and 1600p via docking station, the latter gets resolution only up to 1200p). So, I found this on Amazon: https://www.amazon.com/Cable-Matters-Thunderbolt-DisplayPort-Compatible/dp/B01DYFI1OE/ref=sr_1_3?ie=....It's a Thunderbolt 3 splitter to two Display Port outputs, claiming to support two screens 4K at 60Hz. And it looks like laptop has Thunderbolt 3 ouput. So, will it support all my screens with full resolutions using that splitter? Again, I envision configuration to be:1. 4K display via 1st USB-C (this will be a miniDP adapter with power)2. Splitter via second (Thunderbolt 3), and two other screens (1920x1200 & 2560x1600) connected using that splitter. Will that work? Thanks,Yury

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,

So the trackpoint on my T480s is having this really annoying drift. When I use it heavily and release my finger it drifts for a few seconds in one direction and then it stops. During these 5 seconds or so I'm completely unable to use the touchpad so it can get really annoying sometimes. Other issue I'm having is the middle trackpoint button (the one to scroll) requires more activation pressure than it should. Even after it "clicks" I still have to press it harder for it to actually register. Latest one is poor dim backlit. My T450s and my Macbook Pro have much, much brighter keyboard lightning.  My keyboard manufacturer is Chicony. I already requested a replacement from Lenovo, this new unit is also manufactured by Chicony and its experiencing the exact same issues.

This is more of an intrigue than an issue but I'm still curious as to why this happens. Issue: When placing a T480s on top of another T480s both machines will be forced into sleep mode.  How to reproduce: Line up a T480s on top of another T480s (or T480) and the device will go into sleep mode. I've Stacked T480 units and this does not happen this seems to only affect the T480s line. (These test were preformed on the latest bios/driver revisions) What I think maybe happening is that the T480s when stacked are triggering the lid closed sensor of the other unit. Since this is not the case for the T480 units we have I think it may be because of the thickness of the s models. Is this something that will eventually be fixed via bios update? or is this just a flaw in the T480s design? Thanks for in advanced for your response!  

A:T480s is forced into sleep mode when in close proximity to T480/T480s

I've seen this happen in the past, it was due to how strong the magnets are that keep the lid shut.

Hello, So - the problem appears when you are trying to use external screen which one is connected to the docking station (there is only two DisPlay ports and no others dedicated to monitors).When you connect it first time - it's ok. But when you trying to un-dock and dock again - external screen says "no input" and goes down. In other words - external screen is not working. The same issue is described over there:https://support.lenovo.com/lt/en/solutions/ht081248 Mine docking station type is 40AH, but anyway, I tried to run ThinkPad Ultra Dock 135W firmware update - but update says "the firmware you are trying to install is older than the version already installed. My Docking Station: Power adapter is 135W. All drivers are up to date. Btw - I have many of those docking stations with machines. For some of them everything is fine.But seems the problem is with docking station. I have two docking stations on my desk right now. And my computer on one is working fine, but with other on - not. So, it's clear that the problem is with the docking station.

Anyone owns a P series Thinkpad and can comment on eGPU support? I wasn't able to find any certification on Intel's website or information on Lenovo's website.  

A:P50/P70 Thunderbolt 3 External GPU

I don't think I've read where anybody's actually received a real P50/P70 in their hands yet from a real live purchase.  My own US order for a P70 was placed with Lenovo online last Wednesday night and confirmed by Lenovo last Thursday, but shipment is speculated at no earlier than 10-12 business days.
 
So I don't think you're going to get any firsthand feedback from anybody until maybe January.
 
But who'd really buy a P50/P70 with plans for an external GPU?  The graphics upgrades on the P70 are pricey, but certainly seem "adequate".
 
What is your plan?  Why do you want/need an external graphics capability?

Hello everyone, I was wondering if the Thinkpad P50 will support external  graphics cards via Thunderbolt 3. One product that is available for preorder right now ist the Razer Core which would allow to hook up any GPU with PCIe 3.0 4x speed (but there are several other TB3 egpu enclosures anounced). Razer confirmed that the Core will no prevent other manufacturers from using it but that they might need to do some work on bios and software. I'm a little worried that the P50 might whitelist only some divices over TB3 (as we have seen before with some of the "normal" PCIe slots). Has anybody evidence that it will (not) work, or even has a setup like this currently working? A response, if something like this will be supported, from Lenovo staff would be greatly appreciated. Why would you want this?Spoiler (Highlight to read)Well, the P50 has a formfactor that is still portable and the M1000M / M2000M is powerful enough for work on the go and for some presentations. But for the daily work at my desk I would like to have a little more gpu power. The convenience of having both with one machine is that it eliminates the need to synchronize my softwaresetup and projects between a portable machine and a workstation desktop pc.It also seems like I'm not the only one with a demand like this.

Hi There Guys, I've just purchased the latest Spectre X360 specifically because it has thunderbolt three, which I would one day like to use with an external GPU. I've read in some places that HP are specifically blocking the use of external GPU's on these devices which is troubling.  Its been confirmed that the spectre does not work with the Razer core Just wondering if this is true and if anyone knows whether this will likely change as if there is no support i'll be returning the laptop before it arrives! Thanks, Jason

A:Thunderbolt 3 External GPU Compatibility/Support

Not sure how you return it before it arrives but if you bought it thinking it would support an eGPU you just bought a big disappointment sandwich. We have no way to know if HP will ever issue a BIOS that does support the razer and other similar Tbolt eGPUs but they did just modify BIOS on the Spectre 13 to allow some 3rd party USB-C chargers.

I tried to ask on Reddit but it looks like nobody knows the answer. trying it here  where could I find a confirmation that the T470 with onboard HD 620 graphics can drive two 4K Dell P2415Q at 60Hz monitors when connected via Thunderbolt? PSREFs just say it can support up to 3 displays (which is cool, but at what resolution and what will be the refresh rate) and max resolution supported is 4K at 60Hz (again, great, but how many of them?)I was planning to use either the Startech's Thunderbolt 3 to Dual DisplayPort Adapter or Dell TB16 dock to connect the monitors, as Lenovo is not providing ways to connect two 4K monitors over the DisplayPortIdeally, I'd love to have a dock which can connect both monitors but as I understand current generation of mechanical docks does not allow to use two 4k monitors, I guess it has something to do with bandwidth of chips used for DP ports in the docks.

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...

After the time spent with Dell Support doing diagnostics and updating video drivers to those official Dell drivers on the support page, my new XPS 15 9550 with 4K touch display continues to struggle when using external monitors. I have two (2) Dell U2515H monitors.
I have updated ALL of the drivers and BIOS to the very latest files available on the Dell support page, including the newest Thunderbolt 3 driver.
When the laptop is NOT connected to any external monitors, I am NOT experiencing any trouble.
When the laptop is connected to ONE external monitor via the onboard HDMI port, I am NOT experiencing any trouble.
Trouble begins with the addition of ANY external monitor via the USB-C/Thunderbolt 3 port.
I have experimented with the following three adapters, all producing the same result:

Dell USB-C to HDMI (2.0), part number 047KD7
Dell USB-C Port DA200, part number 5KMR3 REVA00
Cable Matters USB-C to DisplayPort
First, regardless of which adapter. my laptop ramps up the fan for as long as the adapter is present.

Second, although the monitor works with any of the adapters at the proper resolution, all of the screens will go black about every 10-20 minutes and the displays will seem to resize and reset. In this process, about half of the time, the windows open on the monitor connected to the USB-C/Thunderbolt 3 port will either minimize or relocate to the primary display (the laptop screen).

A:Trouble with XPS 15 9550, USB-C/Thunderbolt 3, and external monitors

This is apparently a problem with the Thunderbolt 3 driver/firmware and/or the Intel 530 graphics drivers. I see very similar issues using Dells new TB15 Thunderbolt 3 Dock. Normally when I'm in my home office I use my 9550 with the lid closed using an external monitor connected to the HDMI port. All works perfectly. When I try to use the Dell Thunderbolt 3 Dock and connect my external display to its HDMI port it is unstable. Sometimes the external screen goes blank for a few seconds. When the system wakes up from sleep or I reboot it it does not come up on the external display but I have to open the laptop and switch back to the external monitor. Basically it is unusable. Still waiting for Dell to fix the issues.

Hello - I wish to connect my 24" Dell monitor (it has every port imaginable) to my Lenovo Yoga 720 WITHOUT using the Thunderbolt port. Is this possible? I am a Jazz musician and I with to use the external display for (1) reading complicatedf [e.g., classical piano] sheet music and (2) for use with DAWs (digital audio workstations, such as Abelton, Pro Tools, etc., where there is LOTS of info crammed in tight and a large monitor is needed). My Yoga's TB port is used for a 500 gig Samsung external hard drive.  The Samsung houses my music programs (e.g., the DAWs, Ivory piano, Easy Drummer, etc.), and I placed them there for the fast speed (this really helps eliminate the latency on the pianos).  I don't need fast speed with the monitor; my prior Lenovo G780 worked just fine with my 24" Dell monitor; the G780 had an HDMI port. I don't find a "TB dock" that has (1) HDMI, display port, etc. AND (2) another TB port.  Does such a thing exist? I've tried the crappy "USB montitors."  They (1) suck and (2) are not 24". Am I screwed here? Thanks, - Jeff Newton (Jazz saxophonist and pianist)

On the P52 specs, it says that it can drive 4 independent displays, and for the Thunderbolt ports, the max resolution is [email protected] But what is the max resolution at 60Hz? Can I have the 4k laptop screen, plus two 4k external monitors individually connected to the two Thunderbolt ports, all running at 4k and 60Hz? (when I say 4k, i mean 3840x2160) Link to spec:https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20P52/ThinkPad_P52_Platform_Specification... For reference, here are the specs for the other video ports:[email protected] (DisplayPort via Mini DisplayPort cable)[email protected] (HDMI)Note, I prefer to avoid the HDMI port if possible, due to issues from a P50 I'm currently using, no idea if they have been fixed or not in the P52.

Hello Everyone, I am new here so please go easy on me.I just bought and X1 Carbon 5th Gen laptop c/w Thunderbolt 3.0 docking station.The problem that I have is that the docking station won't recognise any of the external screens that are connected.I am using two Acer screens (one is connected using HDMI port on the dock and the other one uisng Display port).I have tried by connecting just one screen but nothing.I can see that Thunderbolt software is installed and its connected to my laptop.The laptop will charge through the docking station and also the wireless mouse and keyboard will work fine through the dock.Lenovo recommended that i should update my drivers.So I installed Lenovo Companion from Windows store. But it won't update my system. After clicking on System Update, I will get an error message saying "There is a problem in reteriving new updates for your system.Please try again later".Hence I downloaded all the drivers from support website and installed them manually but my docking station is still not working with the external monitors.The monitors works fine when connected directly to the laptop using the HDMI cable. Thanks in advance for your help.

I am plugging in a Thunberbolt SanLink2 10 Gig adapter and it only comes up in wuindows as Bas System Device. Can anyone let me know what I am missing. Thanks,Dan

A:ThunderBolt issues.

The problem you are runnning into is a rather unique one. Very few Windows notebooks have thunderbolt ports. Your zBook is a rare beast in that respect. That is why there are only Apple OS drivers available from the Thunderbolt SanLink2 10 Gig adapter manufacturer. You should consider pestering the manufacturer about producing a driver.  Once there is one available,  perhaps it will be submitted to Microsoft to include in the Windows 10 Driverstore and in the online updates to the OS.

Hello!I have had my P71 for some time and I recently bought an Akito Node. In it, I have a 1050ti and sometimes I can get this to work, othertimes not. I have updated the thunderbolt 3 drivers, and have installed both the discrete graphics/1050ti graphics drivers, and flashed the akito node with the most up-to-date firmware.However, this only works I would say a good quarter of the time.What happens, is: I plug it in, I can't project onto the screen. The graphics card is running.On a whim, I'll install the drivers again. Sometimes this works, othertimes it doesn't. I try a pattern of rebooting my laptop and all, and at most it takes 30 minutes of nonstop installation of drivers/ rebooting for it to work.The best part? If the thunderbolt 3 cable comes loose (which it often does), it stops working and I have to repeat the process I was wondering if there's a solution to this.

Helo, I am trying to connect two external monitors to my HP ProBook 470 (i7-3632QM, AMD Radeon HD 8750M), one with VGA and another with HDMI,  but I haven't managed yet to have all three, two external and laptops built in screen, working. Does this model support having three screens at all? Thanks!

A:How many external displays are supported

Hello,  I have a Lenovo P500 laptop and I'm trying to have 2 external monitors displaying at the same time, and just having the laptop itself closed or with a black screen. I know on Intels website, they state that the processor in this laptop cannot support 3 displays, but what I'm trying to do is just have 2 displaying, but both of them external.  I'm not sure if my laptop is broken or something as well, because when I close it even with "do nothing" selected for when I close the lid the external monitor does not become the default display, it stays as an extended display with the main desktop still on the laptops screen. Both monitors and their connections work until I try to connect them both at the same time, then one of them always goes to sleep. If this is even possible with this laptop, can someone point me in the right direction?
