T580 Thunderbolt 3 to Dual DisplayPort Wont Detect Second External Monitor

Q: T580 Thunderbolt 3 to Dual DisplayPort Wont Detect Second External Monitor

Ok.. I'll try to keep this breif. I bought this laptop SPECIFICALLY for the capability to run 2 external monitors via Thunderbolt 3. I have spent thousands of dollars on the laptop, monitors, and cables and put hours of research into making sure everything was compatible and it won't work. My setup is as follows: Thinkpad T580 with TB3 portTB3 to Dual DisplayPort Adapter(x2)Monitors are both 32" Samsung 1080P monitors at 60hz (NOT 4k) Here's what I have done: Updated display drivers directly from Intel(newer than Lenovo provides)Updated BIOSUpdated FirmwareBought MULTIPLE adapters thinking it was possible an adapter problem.Bought MULTIPLE cables thinking it could be a cable problemI called Lenovo tech support and, after 10 minutes of convincing the tech that my laptop even has a TB3 port he obviously was unable to resolve it so I was mailed a new motherboard and a tech came to my house and swapped the board out. Same issue. The laptop detects only ONE monitor at a time. If I plug them both in to the displayport adapter, one of them will work, the other will say it's not connected. If I unplug the monitor that is on, the previously undetected monitor will immediately be detected and turn on. If I plug the undetected monitor into the HDMI slot it will detect and output. But this is NOT the functionality that I have spent thousands of dollars for. I am out of ideas and now quite sure that, even though the marketing material for this laptop says that TB3 will support 2 displays, it does not.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

T580 (fresh from factory).  Intel(R) UHD Graphics 620 driver (12/27/2017 - 23.20.16.4905).  Intel Core i7 vPro 8th Gen.  Windows 10 64 bit (freshly updated).  Lenovo Vantage system update freshly updated.  (today's date: 4/28/2018) LG display plugged into HDMI port on Thunderbolt adapter which is plugged into the USB-C port on left side.HP display plugged into HDMI port on right side. Either display is detected just fine if I unplug the other one; but when both are present, it only detects one of them. This exact configuration was working fine on my T470, Intel Core i5, vPro, 7th Gen. So, bigger and better (and more $$) is worse. My bet would be on a driver issue.  (Windows won't let me install the Intel April 2018 driver - it says probably because the manufacturer did custom driver coding.)

A:T580 Won't detect a second external monitor

UPDATE: Well, ok, it DOES appear to TRY to "detect" the display when I first plug it in.  But it has no properties (e.g., Resolution) and the #3 icon on the layout panel soon disappears and clicking the Detect button won't bring it back (unless I unplug my other monitor - then it detects fine and works fine).

I just recived me view sonic monitor in the mail to find my laptop does not agree. I have called hp and view sonic, neiter can help. Please Help! I have installed and re installed the driver, I don't know what else to do!

A:Windows 7 wont detect external monitor

right click on the desktop and go to properties, once in there check for a display tab or something like that

if you see 2 'monitors' in there, simple check 'extend monitor'

should work.

if not use the go by from HP, in this example they are connecting a TV and an External Monitor, disregard steps for TV.

Everything is working except - no sound via monitor.  Have updated audio drivers,  Suggestions??

A:Yoga X1 ThinkPad thunderbolt LG Monitor Connected via DisplayPort - No Sound

You might need to enable it. 
 
With the monitor connected, turned on and displaying your computer's desktop:
 
Right click on the speaker icon in the taskbar and select "playback devices." 
 
In the white area of the dialog box, right click and make sure both "show disabled devices" and "show disconnected devices" are both checked.
 
Right click on the various playback devices to make sure they're all enabled. 
 
If you start something with audio, you should see the little green "meters" bouncing on one of the devices. Right click that device and set it to default.

Have read others with similar problems and different types/models of Yoga laptop and none the wiser. Also finding the screen attached to my laptop very diffficult to read . Often text is truncated and I have to adjust zoom to 50% to see whole window. External monitor will also solve this problem. Have downloaded new drivers but discovered they're for different Yoga models so unsurprisingly they don't work. Any suggestions gratefullly accepted.

On the XPS 15 9550, can an external monitor with Displayport inputs be connect directly into the laptop's USB-C Thunderbolt output using a straight miniDisplayport-to-Displayport cable?  Similarly, can a miniDisplayPort to VGA adapter cable be plugged directly into the USB-C Thunderbolt port to drive older monitors/projectors? Or is the TB15 Dock mandatory in order to get the computer talking to  external video devices through its Thunderbolt port output?

Hello Community-  I recently purchased a Lenovo X1 Carbon along with a Lenovo Thunderbolt 3 and two monitors. I have tested out the monitors individually with another computer, and they work fine.  Currently, I have one monitor connected via VGA to the Thunderbolt dock, and I have 1 monitor connected via HDMI to the Thunderbolt dock, which is connected to my Carbon x1. I only have connectivity with the VGA connected monitor, and do not have connectivity with the HDMI connected monitor, although I hear the system "connection sound" when I plug in the HDMI cord.  What is the issue here?  My goal is to have two monitors connected via Lenovo Thunderbolt 3 docking station to my X1 Carbon laptop. Thank you

My external monitor ASUS PB278Q stopped working. I switched out the DP cable which is newly purchased. I have my GPU driver updated and I'm pretty sure I've updated most other drivers on my laptop as well. I'm connecting the DP through the 433835U TP MiniDock Plus Series 3 (https://www.amazon.com/Lenovo-433835U-MiniDock-Docking-Station/dp/B0085MQLMQ). For some  reason the laptop doesn't seem to detect the monitor or vice versa. The monitor says DP cable no signal. Other inputs like the power adapter and the wireless mouse I attach to the docking station do work however. I'm not sure what else I'm looking at. I haven't tried using the other inputs like the hdmi (id have to buy an adapter) or the VGA and the one other one it has since I dont have cable for those... I'm not sure how to resolve this.

Hi all, I am trying to connect 2 external monitors (Asus VW22AT) to my W550S laptop.Via the VGA connection, it works fine (for both monitors, i tried one by one), the display automatically sets to 1680x1050 resolution. My problem comes from the mini displayport which i used with DVI adapter (I also tried with VGA adapter), I can't get the 1680x1050 resolution, it recommands to use a 1920x1080 resolution but the screen is blurred. If I manually set to 1680x1050, the image doesn't use all the screen, each side is black on 3 centimeters thus the image is also blurred. Do you have any solution please?Best regards, Jean

I have a Dell Latitude E7450 laptop with a E-Port Plus II port replicator connected to two external monitors using DisplayPort which will not output to multiple monitors.
I have another Dell model and when placed on the port replicator with two external monitors connected, booting into BIOS/UEFI the screen is cloned onto each monitor. However, when doing the same with a brand new Dell Latitude E7450 only one screen is active - the other is off. Within Windows itself, I can only have 1 monitor connected to the port replicator. If I undock, I can run 3 monitors independently indicating an issue with the dock rather than a hardware limitation with the laptop itself.
I believe the above tests eliminates the OS or driver issue and highlights a compatibility issue between the new Dell Latitude E7450 laptop and E-Port Plus II port replicator. I have tried this on 2 separate machines with the same results. I have also updated both the graphics drivers (Version 10.18.14.4170, A16) and the BIOS (Version A04) to the latest releases. I have also tried using DVI cables as well as swapping out the port replicators. Nothing works. In Windows 8.1 itself, it actually shows as two monitors active, but one is not on. If I swap out the monitors to a different brand, I get the same result.
Is there a BIOS/UEFI setting I need to change? Is there a newer port replicator or update I need?

A:Dell Latitude E7450 compatibility with E-Port Plus II with external Dual DisplayPort monitors

Did you resolve this issue and, if so, how? I have the same laptop (but running Windows 10) and the same docking station with the same results.

Dear All, I am trying to use thunderbolt C to connect to two external monitors for a Lenovo T480s laptop. To do that, I used a Wavlink Thunderbolt C to dual display (HDMI) adapter (https://www.amazon.com/Wavlink-Thunderbolt-DisplayPort-Adapter-Converter/dp/B07CLLX6XS). While the adapter detects one of the monitor and works, it is unable to show the second monitor. The problem is that it detects only one monitor and cannot display in both of them. After reading several posts here, I disabled thunderbolt security from boot menu, restarted the laptop several times with and without the adapter connected. However, nothing seems to work !! Please suggest a possible solution and please let me know what will be the best low budget dual display dock/adapter for Lenovo T480s. Thanks!!Samik

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...

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)

Just found a very interesting problem.  I just purchased a new 27" monitor and connected to my Dell XPS (9343) using a mini DisplayPort to HDMI cable.  The laptop was on and running when I connected everything and closed the lid.  Everything was working beautifully, until I ran WIndows update and had to reboot.  Then all *** broke loose.  The machine started beeping like crazy and the battery charge light started blinking orange then white and then it shut down.  After I recovered from my almost heart attack (I thought my laptop had died)...I opened the lid and hit the power button and it started up fine.  I closed the lid after it rebooted, and continued to work fine.  So as a test, I restarted the laptop again with the lid closed while the external monitor was connected and again the beeping and the orange light blinking.  Proceeded to turn it back on with the lid open...everything fine.  I checked the BIOS settings and everything seems to be normal.   It seems there's a problem with this laptop not being able to be restarted in the closed lid position when an external monitor is connected (something I do ALL THE TIME with my Lenovo work laptop that is also connected to an external monitor).   Has anyone else had this problem?  Is Dell aware of this issue??

I recently got a Dell XPS with Thunderbolt 3 technology for work, but also have a 2011 iMac with Thunderbolt.  I am wanting to use the iMac as an external monitor for the Dell, so I found a Thunderbolt 3 to Thunderbolt adapter to utilize TDM.  However, I have not had any luck making it work when pressing command-F2.  Through my research, I've found that using a pre-2011 iMac with a mini display port and a PC with a mini display port has worked no problem.  I've also found that using a post-2011 iMac as an external monitor with a PC should also work no problem if both computers have Thunderbolt technology.  In addition, I contacted Apple Support and they told me my connections should work since I have stepped the Dell's Thunderbolt 3 down to Thunderbolt, and connected the two machines via a Thunderbolt cable.  I am able to tell that my Dell recognizes the iMac, but have no way of knowing if the iMac recognizes the Dell.  Is there something that I'm missing?  Is there software that would make this work?  Has anyone had success getting this to work?  Any input would be greatly appreciated.  Thanks.

I recently purchased an XPS 15 9550 with i7, 16 GB RAM, 256 GB SSD, and GTX 960m dGPU that I have connected to a 27-inch QNIX qx2710 2560x1440p external monitor. I have this connected through a Cable Matters USB-C/Thunderbolt 3 to DVI-D adapter and cable.
The monitor and everything seem to work fine at 60hz, except for every time I unplug, turn on, or restart the monitor/computer the first five or ten minutes of use is plagued with constant screen flickering and flashing. After ~five minutes the monitor seems to stabilize and will only rarely have a single screen flicker. 
I have read other forum threads describing similar issues with different monitors/cable setups and that there is likely an issue between the wifi card and thunderbolt port. The common recommendation is to turn down the wifi output percent to 75%, however the Killer wifi card on this computer does not have an option under advanced settings to turn down the power output. Has anyone had any luck doing this on a recently purchased XPS 15 with the Killer wifi card?
The cables and adapters are new and the BIOS and all drivers are up to date. Other than the wifi issue, does anyone have suggestions or solutions to this screen flickering problem?

(For those of you who have followed my previous threads, I've now ordered a T580 with 4k display). I'm looking for a T3 dock which can do the following on a T580. It would allow me to use just one cable to dock/undock it: 1) Attach a screen with a 2560x1440 resolution with 60Hz (digital connection)2) Attach a screen with a 1920x1200 resolution with 60Hz (digital or VGA connection)3) Full Ethernet port4) Charge the laptop (originally, it comes with a 45W power adaptor)5) Have at least 1 classic USB 3.0 port Unfortunately my budget is limited so that I can't go for the original Lenovo one. If there's a dock which can all the above except for attaching two screens, then this would be ok as well, for the time being (assuming I can run one screen via the dock, and the other screen directly from the HDMI of the T580). Then it would just be 2 cables for docking/undocking...

It's running the latest build (non-targeted channel) of Windows 10 Pro with all Windows updates and all Lenovo System updates installed (through Lenovo Vantage app), as of this writing.The laptop has only professional/scientific software installed and it's strictly used in a work setting in a climate-controlled office (i.e. no exposure to extreme heat/cold, humidity, dust, etc.) (scientific/professional software like statistic analysis software, Office, browsing company websites and other non-entertainment professional sites, etc.) and there have been no system registry modifications, no 3rd party driver installation, or anything outside of the normal functioning of the system. Windows has never been re-installed/reset from the factory-shipped condition, and I haven't even accessed the BIOS for the first time since it was purchased. There's > 250GB free from the 1 TB SSD, and RAM utilization never reaches > 50% even on the heaviest of workloads. IssueUp to Win 10 OS build 1607 back in 2016-2017, everything was running well. After installing builds 1703 and then 1709, and still now after the 1809 update (updated a couple of months ago, but nothing changed with that update), when I connect the laptop to external monitors (either to one or two 27-inch, 60-Hz 2K monitors [AOC Q2781PQ] outputting at 2K resolution), either...

Hi all, I have a Thinkpad T580 and a Thunderbolt 3 Dock Gen2. It worked fine until now.I updated the Dock Firmware, and everything worked. I updated the BIOS from 1.21 to 1.22, and Thunderbolt is not working anymore. Were I work we have many Lenovo Laptops and Docks. I tried another Dock, but the thunderbolt software does not show a connected device. I reflashed the 1.21 BIOS version, but thunderbolt stays broken. How could that happen?I even set the Thunderbolt Security to "no Security" in BIOS, thinking it might have broke security, but no, does not work. When I plug it into USB-C it works, of course. But this way I only have 10GBit/s for everything, not 40Gbit/s like with Thunderbolt. That means not all of my monitors do work and bandwidth is limited. Any ideas how to remedy the situation? Best, maybeapreacher

A:Laptop wont detect external usb HDD

A few things it could be...
1) A power issue. Are you trying this with the laptop running on the AC adapter ? ?
2) A HDD problem. Try hooking that drive up to another machine and see if it is picked up.

The issue with USB2 is not the problem as the unit was working at one time, but you can check your MBoard manual and it will tell you what type USB you have.

After the Thunderbolt firmware update, I'm now getting terrible white level clipping on my external monitor. I'm a photographer using a 100% Adobe RGB monitor calibrated with DisplayCal and a Spyder 4. Until updating the firmware, I had 0 problems. Now, compared to before - and compared to other computer attached to the same monitor - the contrast is completely wrong. All RGB values including and above 244 are clipped to 255. This is obviously a huge problem. I've uninstalled all of my calibration software, and removed all my color profiles from Windows Color Management, so Windows should revert to the default profile. Still, the same problem! What is going on? I never had this problem, until the update!

Hi benjaminbusch, Can you be precise about WHICH update you are referring to please (e.g. provide a link). Thanks!

Both PSREFs claims [email protected] over Thunderbolt but I thought the dual port controller (even in Alpine Ridge and I suspect these will be Titan Ridge) always had eight lanes of DisplayPort fed into it which is enough for 5K @ 60Hz. So what gives?

Hi there,  I've been experiencing issues with both Thinkpad T580's and 5th/6th Gen X1 Carbons. Basically any model that has USB-C/Thunberbolt connectivity.  I have had users report that their laptops either connected to their docking station or power adaptor  do not charge. Windows reports "Plugged in, Not charging", and power drops. The dock does not appear to work, external screens, network etc.  When disconnected from the power source or dock, the orange power light on the left site where the USB-C connector is stays on. This is the light that comes on when charging. When the laptop is shut down, the same orange light stays on.  The work around I've found is to go into the BIOS, Power settings, Disconnect the internal battery. (External battery needs to be removed for the T series). After selecting this, the laptop powers off and the orange charging light goes out. Once reconnected to a power source, the laptop will power on, work with the dock and properly charge.  I have encountered this on multiple T580's and multiple X1 Carbons. I've attempted to run the System Update utility (excellent app btw) and made sure BIOS and Thunderbolt firmware etc is up to date, yet the issue still persists. Logging into the BIOS and disconnecting the internal battery is not a viable solution.  Is there a solution for this, and are Lenovo aware of this issue?  Thanks,Adam

HI All,

its been 24 hours since my Win 7 ultimate edition installation, and still i have not managed to get my dual monitor working.

I was running Vista OS for 2 years and was working everything fine. But now with Win 7 my second monitor (Samsung Syncmaster 2333) is not being detected.

I went in the Asus driver page and it seems that for the Standard Vga grafic card there is still no driver for Win 7, is this possible?

If it is really like that, how can I get my dual monitor working? I thought about buying an external graphic card...is this the only solution or am i missing something?

Any help is appreciated!

Thanks,
Gabriele

A:Standard VGA (Asus) does not detect dual monitor with Win 7

To tell you the truth i heard ways of doing this but your onboard vga adapt might not be strong enough for dual screen support

I can tell you i run dual monitors off the same vidcard im sure i can throw a third one in the mix off my vga but your mobo should give you the specs on the onboard adapter where it should give you in full detail the capabilities

If not i suggest getting a video card that fits the bill also make sure you have adaquete power to supply the card or the upgrade will be meaningless

Hey everyone!
I'll get the specs out of the way first. I have an HP dv9000 (2007) and a Macbook Pro (2009). For the longest time I've backed up my PC on my SimpleTech 250GB external hard drive, which is USB powered (plugs into two ports) I recently installed XP on my Mac so I formatted the external drive and backed up my Mac with Time Machine on the it.

Anyways, now I want to sync it back with my PC. I connected it, and I could hear the drive attached noise, and it also shows the 'Safely Remove Drive' option, however it isn't listed under My Computer. In the device manager, I can see it under Disk Drives as 'Hitachi HTS.... USB Device'. I checked to update drivers and it said everything was up to date and it claimed that it was working properly.

Any ideas on how to format it so that my PC will list it under My Computer?!

Thanks in advance!!!

Hey guys...newbie posting out of total desperation and needing help!

I bought a Samsung SH-D162D DVD Drive in a USB enclosure to connect to my Toshiba Windows 7 laptop via USB.

I cannot get windows 7 to find it! When I plug in the USB cable the balloon comes up to say it has been installed, I can see it on My Computer for about 1 or 2 minutes then it drops off. It isnt listed in my hardware or anything.

Its not found in Disk Management or My Devices so it isnt a case of changing the drive letter - i cant find the drive to change it.

I have also tried to find the upper and lower settings in regedit....couldnt find them so couldnt delete them as advised in other posts of this nature.

It is set to master, the IDE connector and power connectors are fine. Its gotta be a windows 7 problem cause it does show up very breifly. In the minute or 2 its there I cant do anything with it...it just hangs although it will open and close. Ive googled it and cant find anything...mainly registry issues but they didnt help.

Ive also connected it up to another laptop with XP and had no problems so I know the DVD Rom works fine and all the cables are ok.

Ive tried in all 4 USB ports on my laptop and also turned off all energy settings...all with no luck. And I also have EVERY windows 7 update...

Heres exactly what happens from power off on the enclosure.

1 - I plug in the USB lead then turn on power to the enclosure.
2 - I quickly go to Start, Computer and I can see the DVD Rom... Read more

I have a Thinkpad X1 Extreme (20MF000CUS) connected to two external 4K monitors via Lenovo Thunderbolt Workstation Dock (40AN0230US). Windows 10 desktop extends to all 3 displays.Everything works really well except for a major annoyance: normally I have a bunch of apps/windows I leave open on all 3 monitors. Whenever I put the laptop to sleep and I then resume it later on, all app/windows I left open are automatically resized, moved and stacked up on the primary (laptop) display. Is this by design? Anyway to prevent this behaviour?I noticed that the laptop display is handled by the Intel graphic card while the two external displays are handled by the nVidia graphic card. Could this be the reason?
