Hi!I just got a new "X1 Carbon 5th Gen - Kabylake (Type 20HR, 20HQ)" and a "X1 Carbon Thunderbolt 3 Dock". I have an external screen connected to the dock and it works fine (VGA connection). I also have an other monitor with display (DP) connection that I want to use. But my computer can't find the other monitor, only the one with VGA connection. Is there any easy ways to fix this problem?Best regards

We have a X1 Carbon 6th Generation with 40A9 Thinkpad USB Dock. The monitors will randomly flicker for 1 - 2 seconds. Other times it'll flash so much that the computer has to be rebooted Tried the following-Send back to depot. They replaced system board and issue persists-Ran Lenovo firmware updates - issue persists-Tried a suggestion from a Lenovo forum to Enable Thunderbolt BIOS Assist Mode and reboot then disable and reboot Has anyone else had this issue and if so are there any suggestions? Thanks!

Hi, Working in a helpdesk, got a user that has a brand new X1 Carbon 6th gen. She plugged in a monitor-only docking station.Both of the screens are working, using both VGA and HDMI ports, as well as with an adapter that goes from HDMI to DisplayPort. However, as soon as both screens are plugged in, one in VGA and the other one through DisplayPort (or even HDMI plugged in directly to the computer), only one screen is detected. I made all the updates going from graphics to BIOS through the Lenovo System Update app. Any tips?

Hi, I am currently using the ThinkPad Mini Dock Plus Series 3 - 170W with 2 x 1920x1080 displays @ 60Hz a display. I am doing so by connecting one of the monitors to the DVI-D output on the docking station and 1 to a USB to HDMI converter (I was having issues with the VGA for some reason). I also use the laptop display as a third screen in the setup. What I am looking to do is purchase 3 x 2560x1440 displays and have the docking station power all 3 of these @ 60Hz. I understand that I can only use 2 display ports to do this so I intent to add a USB32DPPRO to achieve this, however my question is will they all run @ 60Hz. I have found this link which confirms I can run 2 displays at the resolution I'm after, but it does not mention anything about the refresh rate. https://pcsupport.lenovo.com/gb/en/solutions/migr-76767.  I'm just a little confisued as when you start looking at refresh rates on 4K for example, it says you can only run 1 screen @ 60Hz and if you add another screen the refresh rate drops to 30Hz for both. This is when used with the ThinkPad Workstation Dock 230W. More information here https://support.lenovo.com/gb/en/solutions/acc100247. If anybody could help demistify this that would be great! I am using a NVIDIA Quardo K1000M as my GPU and the Inter(R) HD Graphics 4000 for the onbaord graphics.

Hi,
 
The way I read the X1YG1 base specs it supports two independent monitors.  Apologies, but I can't quite parse your post.  Does "apart from laptop screen" mean that you want 3 monitors total, or two and the laptops's display is off?
 
supports external digital monitor via HDMI or Mini DisplayPort;supports dual independent displays;

I have a Thinkpad T430 type 23474W4 and a Thinkpad mini dock series 3 type 4338-15U. I already have a Lenovo LEN LS2223wC monitor hooked up to it through one of the DVI ports. I have a a Lenovo LT1952p Monitor that I would like to use as a second external monitor. Both monitors work individually through either DVI or VGA. However, I can't get them to both work at the same time no matter what configuration I use. I was told they didn't have to be identical monitors to work together. What am I doing wrong?

I posted a similar question earlier and people referred me to the Yoga (much appreciated).  However, I was interested in the 2.6 lb carbon version with touch screen capabilities.  Asus has a Spin 7 model that is very good at 2.65lb, but I miss the red mouse toggle in the middle of the keyboard and Asus's track pad was designed too large....causing unintended tapping.  The Yoga, while nice, is heavier than I was looking for.  The 14 inch screen is about 3.3lb? the 12 inch at 3? I thought that some of the earlier Thinkpad Carbons had touch screen and was hoping they would make a return soon.  Thanks,

Apologies if something similar has been posted, I just can't find the answer. We have a 5th Generation Thinkpad X1 Carbon connected to a Thinkpad Thunderbolt 3 dock. At the moment the display is mirrored using a VGA cable to connect to the dock. What we would like instead is to connect the dock to 2 external monitors with separate content on each monitor and the laptop display blank. I just can't figure out if this is possible, what might be needed, and how!

Hello friends! I have an X1Carbon 6th gen that is less than 6 months old. Everything used to work just fine, but lately the following thing happens:  The laptop won't detect that I hotplug an external monitor. It will only detect it if I shutdown the laptop and press the power reset button for a few seconds. I learned this technique from this forum post:https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-6th-gen-HDMI-not-working/m-p/409265...However, my experience does not fit that post, since I never see the Thunderbolt controller in the device manager, even after I do power reset; still the monitors are detected just fine... For this reason I also can't install the thunderbolt sw and fw drivers since it tells me that the thunderbolt adaptor cannot be found. I have the latest BIOS firmware 0.1.31.  This is really annoying and really breaks my workflow... Any idea what might be the issue? A milion thanks! <3

After making a long term decision of not buying the newest 6g X1 Carbon because there are still some things that trouble me a little, i've listed some improvements i think that need to be made before i can consider this the perfect laptop it almost could have been (in order of importance):change aspect ratio (something like 3:2)improve reflection on HDR screenmake machines compatible out of the box with widespread linux distros like ubuntu out of the box (no driver issues, no deep sleep bugs,...)option for no fingerprint reader (it kills the design a little bit and there are some people who still dont use it at all; i know you can deactivate it)updated webcam (could be considered an important thing for some business people if you ask me)updated speakers; the ones being used now are on the low end of "OK" and i think there is def some room to upgrade even if its not designed as a media deviceof course if possible id love to see some graphics and RAM upgrades aswell but for a notebook as thin as this one i think those specs might need to suffice for another 2-3 generations.et another thing about blowing air outside the right side where your mouse potentially is could get a rework aswell.let me know what you think; obviously everyone has different wants and needs for a machine but if the maxed out or even just standard device is that expensive some of those suggestions above could ...

When you turn on the laptop all you get is the back-light.  You don't get the splash screen, POST or anything else for that matter. I've tried using the FN+F7 to make sure it wasn't set to projector mode but that didn't do anything.  It's like the power cable to the LCD is connected but the data cable is disconnected.  I suspect this is the case due to the screen going "weird" as the user puts it.  I also suspect that it might have been dropped. What I am wondering is if there's a BIST (Built-in Self Test) for the LCD or anything like that.  I'd love to avoid the support charges. Also, the numbers on the white tags on the back of the laptop have worn off, is there a way to get the serial number without the original paperwork?

Over the last few months I've had around 7 different occurances of a monitor not displaying anything while powered on and hooked up. This has happened with multiple makes and models of monitors and also laptops, even the connections are different in some cases whether it be VGA, VGA to Mini display, HDMI, or HDMI to Mini display. The only similarity of all the occurances is 2 monitors were used while this happened. Each time I've replaced all the adapters and cords to see if that would fix it. The only thing that seems to fix it, is to switch the monitor out with another one. This happened after the founders update for Windows. All PC's are using Windows 10 64 bit.

I suspect some new updates might have caused the problem (probably new intel updates) Please let me know if you have any suggestions (I have already tried almost all solutions in other blogs/websites)...

I have a brand-new ThinkPad X1 Carbon 6th Generation, a new ThinkPad USB-C dock, and 3 external Dell U3014 displays, which have a maximum resolution of 2560x1600. I want to run all three external displays at full resolution, with the built-in display turned off. Right now, with 2 of the displays connected to the dock's 2 DisplayPort ports, and the third display daisy-chained to one of the first two using a DisplayPort cable, I have all 3 displays connected and working, but only at the following maximum resolutions: display1 at 2560x1600, display2 at 1440x576, display3 at 1440x576. The Lenovo Platform Specifications sheet for my ThinkPad says that the Intel UHD Graphics 620 chip in my laptop supports "three independent displays" with maximum resolution of [email protected] (for a USB Type-C connection) or [email protected] (for an HDMI connection). So, I think that my laptop graphics chip has enough power to drive all three displays at their full 2560x1600 resolution.(see https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20X1%20Carbon%20(6th%20Gen)/ThinkPad_X1_C...). I've downloaded and installed the most recent driver for the Dell U3014 displays. So, I'm guessing that my laptop and display drivers are fine, and my dock is the bottleneck. Can anyone tell me how to get all three external displays running at their full 2560... Read more

I have a ThinkPad E550 laptop connected to two Acer V246HL monitors via a ThinkPad OneLink Pro dock. One monitor is connected via DVI/HDMI to the dock and the other connected either via VGA or DVI/HDMI directly into the laptop.  When both are connected via DVI/HDMI only one monitor will be detected. When one is connected via VGA both monitors are detected, however the one connected via VGA will flicker or blink off and on. Disconnecting the ThinkPad dock solves this issue. I have tried the following:Uninstalled and reinstalled graphics driversUpdated dock firmwareRun updates on graphics driversChecked different cablesChecked different monitorsChecked different dockChecked different laptopRun Lenovo VGA fix The Lenovo VGA fix would not complete and ended up in error loop. After advice from the internet I unplugged the dock and tried again, but failed. I then unplugged everything but the VGA cable and tried again, but failed. I unplugged all peripherals and tried again, but still failed. Errors include "Invalid AUX device" and"Enable Aux2 Reg Failed".Finally I redownloaded the fix, unblocked everything before unzipping then ran as Administrator, however it all still failed. Any other advice? I can run off battery for a while but not for a full working day.

Laptop: Thinkpad T430s with Intel HD Graphics 4000 and Nvidia NVS 5200 M - 1 Mini Displayport, 1 VGAExternal Monitors (2): Dell U2415 - with Displayports and HDMI (no VGA or DVI ports on the monitors) Current setup:Monitor-1 (main display) is connected using Displayport - resolution 1920x1200Monitor-2 (extended display) is currently connected with HDMI using VGA to HDMI adapter that is attached to the VGA port on the laptop. However with this setup resolution on Monitor-2 is restricted to 1920x1080 I also have a docking station - Thinkpad Mini Dock Plus Series 3 - Type 4338.This has 1 VGA, 2 Displayports, 2 DVI-D ports. I tried the following options with 4338 but none of them worked.1. Connected both monitors using two Displayports on 4338. Only one of the monitors was recognized (1920x1200). Other monitor was not recognized at all.2. Connected monitor-1 to Displayport on 4338. Connected monitor-2 to mini Displayport on laptop. Only monitor-2 was recognized (1920x1200). How can I achieve 1920x1200 on both external monitors - with or without using the docking station 4338? I don't plan to use the laptop's LCD screen.  Thanks for the help.

Hi all, I have a Yoga 260 and two external monitors.  It does not seem to matter how I connect them, USB, HDMI, whatever the thing with a square on one end and USB on the other, directly or through a splicer I can not get the Yoga to recognize the third screen individually (yoga has one monitor, plus 2 external monitors = 3). I go to display settings but it just will not recognize the third monitor at all unless I use HDMI out of the laptop in to a splicer then 2 HDMIs out and in that case I only get duplicates on the two external screens. Any suggestions about the best way to set up... as in "it worked for me when I connected USB to one monitor, then daisy chained that to a second one" or "it worked for me when I HDMI to one screen and USB to a second" etc... Thank you

A:Lenovo Thinkpad X1 Carbon 20A7 Thunderbolt

Why are only W540 and W541 listed as the supported models? Are you saying it will work with X1 Carbon as well? What kind of devices can you use once that driver is installed?
