While Lenovo doesn't supply a driver for the display adapters, the chipset inside it (and as far as I can tell, all other USB 3.0 to DisplayPort devices) is provided by DisplayLink. You can install the generic DisplayLink adapter drivers directly from their website at:

I am using the Lenovo usb 3.0 dual monitor docking station with the new beta drivers March 13 2015. I think they got it right now. No more screen blinking when watching videos and ethernet is working great. I have Mac Book Pro 15.4 11.2 Mid 2014. This is my first mac.

I have a Lenovo Y560 (Win 7 x64). When I restart my laptop I get to the Windows boot logo and then the screen goes black. I am able to boot into Safe mode but if I then try and restart I get the same thing. The only way to boot into Windows normally is when I disable my AMD Mobility Radeon HD 5000 graphics drivers via Safe mode by going to Device Manager. This will boot the system without issue. I figured I would do this (disable graphics drivers in safe mode) then enable the Graphics drivers once the laptop boots but when I do Windows tells me that I have to restart Windows for changes to take affect which takes me right back to the problem I'm trying to solve.

I would like you to uninstall the ATI driver via safe mode, then boot into normal and try to cancel off the installation. if you're able to cancel the ATI driver installation in normal mode, kindly try the following steps.

In the first case I can use only one of my displays (either the one built-in or the external one; seems to be random, which one exactly). In the second case I can only use one resolution (2560x1600) on my built-in screen, which is too small to see things.

DisplayLink Manager is a new way to enable your DisplayLink dock, adapter or monitor on macOS platforms. It's an application that combines our latest driver with features that streamline the setup of mutliple displays up to 4K.

This all helped though. But for me, I had to go to device manager and i saw a Wacom human interface device with a ?. I tried to update the driver automatically, no worky. I did the manual update and the touchscreen started working!!! good luck

Hi 

Few methods may helpful to troubleshoot this issue. 

1.After open Device Manager, under Human Interface Devices section find HID-compliant touch screen. Right click it disable and then re-enable. 

2.Go to Settings > Update & Security > Troubleshoot > launch the Hardware and Devices Troubleshooter. Check if it could fix. 

3.According to your machine model, go to lenovo's official website to download Touch Screen Driver to reinstall. 

4. Is this a new problem recently? Check for update if some security updates need to be installed. This could update Windows OS version and system files. 

5.Contact Lenovo support to test if it is related to hardware. 

Hope this helps and please help to accept as Answer if the response is useful. 

Best Regards,

Somewhere along the line I read that the Video Manufacturers drivers were more advanced and got them from Intel for the HD 620 and Nvidia for the M520. At this point I am unsure whether I have a Lenovo or Intel or Nvidia drivers currently installed. I did have to get the Nvidia control panel from the Microsoft store, if that helps. Ver 8.964.0. M'soft store will not update this. In fact, the M'soft store seems broken. GET does nothing.

Device Manager shows Intel as 30.0.101.1191. Nvidia as 31.0.15.2889. Lenovo downloads ( I am thinking the Lenovo driver might be better optimized for the dock) seems to have Intel at 30.0.100.9865 (Older) and Nvidia at 31.0.15.2908 (Newer). Actually appears this driver from Lenovo has BOTH an intel and Nvidia driver in this package! Unsure, once again if mine came from OEM or Video Manufacturer. Lenovo Vantage shows no new video drivers to update, which in itself is odd.

So, now need advice. Can I update with these downloaded drivers from Lenovo "over the top" of what is installed even if a tad older? This: Versions 31.0.15.2908 - n1vda45w.exe (NVIDIA Graphics Driver) 30.0.100.9865 (Intel Graphics Driver) package might be the trick if so.

I always get my heart in my throat when a driver changes to Microsoft VGA and I lose window sizes, desktop layouts etc and feel it may never come back:) So I hate to uninstall first. But I would like to solve this.

I'm sure there are good clues here, just not sure what they are! Both Firefox and Edge are using the Intel HD620 graphics. If it were the dock or monitor, why not with Edge? If the browser. why not undocked? If the driver - virtually same questions. If the monitor, why not in Edge?

Based on the information shown in the SSU document, we can confirm that your computer is actually working with a dual graphics configuration. It is using Intel HD Graphics 620 with driver version 30.0.101.1191 and also NVIDIA Quadro M520 with driver version 31.0.15.2889.

For this scenario, it is important to mention that it is always recommended to install the graphics driver provided by the manufacturer of the computer, since that driver was customized by them to work with your specific platform.

I looked on Lenovo's website and the latest graphics driver version they have available is 30.0.100.9865 which is critical. For the Nvidia graphics card, the latest version they have available is 31.0.15.2908. Please try a clean installation of those drivers following the instructions in the links below:

So - it is NOT Firefox.

-it is NOT the laptop (but perhaps driver)

-it does not seem it could be NVIDIA GPU or driver

-it is NOT the montior.


It is either the dock - and it errors this way on either DP or HDMI ports so not isolated to one port, OR the Intel video driver which seems most likely. Memory is not what it once was, but seems this started when I changed from the Lenovo to the Intel driver as mentioned above. And since I have two identical docks, and both do it. And I do not recall this always being the case, I think this must be.

I now recall why I wanted to change Lenovo drivers as the Lenovo version 30.0.100.9865 had (has!) a runaway memory leak in DWM.exe. This is the latest Lenovo has and is not fixed.! Since the Intel driver seems to be a VERY possible culprit for the Dock / Black Screen issue, I will likely have to find an older Lenovo driver. I will have to go back to a 2022 version before 9885. n!vda41w. And I am more confident that the black screen issue started when I "updated" video drivers.

Becoming awfully complex. But hate the black screens! Will await your best/easiest/safest method for changing to these older Lenovo drivers. I have removed NVIDIA RTX Desktop Manager. I have their latest control panel from the Microsoft Store. I have Intel Graphics Command Center installed and assume I do not need to remove that, yes? And would be so nice if I could run "41w" and have it overwrite all.

You might try a clean installation of your graphics drivers, using the proper latest Intel generic graphics driver. However, Intel's generic graphics drivers from the Intel website do not work on some computers that support Switchable Graphics. It depends on your computer's hardware configuration. If you encounter problems using the generic driver, Intel recommends reinstalling the latest validated driver from your Computer Manufacturer for your system.

That said, interesting point on Optimus. Where does Optimus live? In the Intel driver? Someother utility? That will be helpful to know which is the latest driver for the HD 620 (as i asked above for confirmation). I am using YOUR 30.0.101.1191 at this moment and I belive even Intel had previously confirmed that Optimus is enabled. So please help me out here with a bit more information.

As previously provided for a clean installation process, the latest Intel generic graphics driver is 31.0.101.2125. What do you mean by Optimus? If you are referring to the Tesla robot (Optimus), please be aware that is out of our scope.


The last available driver at Lenovo is 30.0.100.9865 Which still has the acknowledged DWM runaway memory leak (well known and documented by Lenovo. Which is what drove me to Intel drivers, but perhaps a newer, if ever, Lenovo driver would solve this issue.


Jocelyn, I would suggest brushing up on Video Driver Knowledge. "Optimus" is a long established technology to switch from integrated graphics to the dedicated GPU and COUNTLESS laptops have these combination drivers, for example Intel and NVIDIA. Countless. Tesla??? Please.

And I will go a stretch and say there a MILLIONS of Lenovo laptops with Lenovo Ultradocks in use daily around the world with INTEL video drivers and no issues with 1-3 monitors connected to those docks. Indeed, Intel supports that. ff782bc1db
