Dell DisplayLink Setup Guide

ORIGINAL POST

I had some trouble getting my monitors to work via a docking station, but I found a solution and wanted to share my insight. Hopefully, it helps someone.

First, install displayLink
Check if this file exists: /usr/share/X11/xorg.conf.d/20-displaylink.conf
1. If not simply write: sudo nano /usr/share/X11/xorg.conf.d/20-displaylink.conf
2. And insert following text:

Section "Device"
    Identifier "DisplayLink"
    Driver "modesetting"
EndSection

Reboot

Why do the settings for 2 Dell 4k monitors look different have different settings? I am using DisplayLink Manager with a USB-C hub.

Go down to the Advanced button. Toggle whether or not to show resolutions.

On results in the list of resolutions like the top of the picture where you can also ask to see all resolutions. Keep in mind though that 2160p native 4K may look zoomed out without scaling.

Off results in the horizontal 5 options in the bottom half of the picture. The middle should do upscale 4K but with scaling like 1080p so that the display doesn't look zoomed out like native 4K.

Interesting, I can see what you are saying and it does indeed work for the 1st Dell monitor. But the second monitor (that is already showing the resolutions in a list) isn't affected when I toggle that "Show resolutions as list" setting. It just stays the way that it is showing the resolutions in a list

edit: The 1st Dell monitor is connected via HDMI and the 2nd is connected via DisplayPort in my USB-C hub if that makes a difference

For clarity, are you trying to view the display options for the second monitor as scaled options, like in the bottom half of the picture? Or are you trying to view display options as the list of resolutions like the top half of the picture?

I want both of them to be like the Dell S2721QS (1) (bottom image) where it has a 4k resolution but the UI and text is scaled to the middle option (3008 x 1692).

Is there a way to do this?

edit: I have an M3 Pro MacBook pro and am on the latest version of MacOS Sequoia

Bypass need to install Displaylink drivers via hardware?

Posted by [deleted] · in r/UsbCHardware · 1 year ago

I have a macbook that does not have a displaylink driver. I want to plug the macbook into some kind of dock will "inject" a displaylink signal .

I don't get why mac users need to install a driver to share their screen over for instance a logitech swytch for conferencing. I would like to have a dock or something between the mac. I mean I can plug in my mac fine to a monitor with usb-c , so why must I need a driver to connect it to a display link peripheral?

There is even an article how to deploy drivers, but imagine if you are a guest for some organization and you don't have the driver installed. you are screwed and cannot share your screen!

I'm looking for any advice on some hardware that would allow you to bypass the requirement of having a driver installed.

display link was designed before USB C with a video signal over the cable was a thing. The display link protocol wraps display signals in USB 3.0 data packets

USB 3.0 is more compatible but clearly we are moving towards newer standards.

spydormunkay · 1 year ago

There is no bypass as the DisplayLink chip Logitech uses requires it. It is not normal graphics. It is CPU-driven graphics over USB protocol.

The reason why your monitor works without a driver as it’s normal graphics processing like over a GPU with USB-C DP Alt Mode. Under the hood it’s just physical DisplayPort over a USB-C cable medium.

Some monitors and devices have switches that can switch between DisplayLink and DP Alt Mode, but those are rare.

Is it only the Logitech Swytch that uses DisplayLink I wonder? Hoping to ditch the Swytch entirely and try to plug in the laptop directly to the rally bars hdmi input with a long optical thunderbolt 3 cable and adapter. As far as I know the bar has simple HDMI input and doesn't require DisplayLink.

This is the device I'm hoping to get rid of: https://www.logitech.com/assets/66004/swytch-qsg.pdf

Either way, this is some helpful info for me to learn. Thanks

DisplayLink is crap, why would you want to use something that is using USB3 protocol (which has so many design problems) to emulate a framebuffer when you can just use a dock which takes the DisplayPort stream from the computer?

jamvanderloeff · 1 year ago

A (mini) PC set up with an HDMI capture card with software displaying the input full screen could work, but it's a bit silly and would add a little lag.

The nicer way would be if logitech implented DisplayPort over USB-C and/or Thunderbolt support on the Swytch's input thing, but that'd add cost on their end so good luck with that.

3 upvotes on reddit

[deleted] · 1 year ago

Yeah an intel Nuc would perhaps be a little overkill, but seems like the only solution. I was thinking maybe having one with two thunderbolt 4 , then mirroring the display input. Hoping Logitech comes to their senses and make an update to the hub. The swytch alone is like 1000 USD, so hopefully they can bear the cost....

Would be nice of course if the driver wuold come preinstalled on macos , since Displaylink seems like an established "standard" of sorts. It's just messy is all

1 upvotes on reddit

jamvanderloeff · 1 year ago

A Thunderbolt port on a NUC still isn't a video input so would still need a separate capture card plugged in, if 1080p 30FPS and a bit of JPEGy compression is acceptable there are tons of dirt cheap USB HDMI capture devices now like https://www.amazon.com/Capture-Streaming-Broadcasting-Conference-Teaching/dp/B09FLN63B3

Apple wouldn't want to ship DisplayLink drivers as standard because they'd want to sell you the Apple TV (or other AirPlay licensed things) instead :^)

Presumably, this is posted here because this setup worked with some other OS?

Yes, it worked with Windows Vista that was originally installed on this Dell laptop. I'm trying different monitor emulators that can be encoded on the Comet KVM using older analog monitor EDIDs to see if it will work with It.

I was able to use the Comet and Dell together using the VGA-to-HDMI when Windows Vista was the OS using the default displays available on the Comet, but since installing Linux Mint, I have not been able to get a signal remotely except at the login screen.

I hate Dell Display Manager 2.0 so much. The hotkeys just don’t work with it - at least not the way they did in v1. It’s a silly idea to want to move my cursor to the active window to then use the hotkey I set up to switch inputs, plus it doesn’t save unique hotkeys to each monitor like the previous version. Terrible interface and design. I also went back to v1. Worst thing is I had 2.0 also installed and when I ran it, it wouldn’t even allow me to back to using the previous version. Instead it said ‘Use Display Manager 2.0.’

Only after I uninstalled 2.0 would v1 work again. Glad you found it.

New XPS 15 (9500) 4K HDMI Dongle Guide

Posted by DimensionSoft7510 · in r/Dell · 5 years ago

Hey floks, I recently was looking to get 4K @ 60Hz HDR out of the XPS 9500.

I went through some very disappointing threads stating that 4K support was very limited until I decided to make some experimentation myself by buying a bunch of dongles.

I created this spreadsheet to register how the dongles worked, have a look: https://docs.google.com/spreadsheets/d/1A1KKLfCDwowODF7cinnvxecnagUyj7XjYeer7dfludA/edit?usp=sharing

These are my conclusions:

It's possible to get 4K@60Hz HDR (8-Bit with dithering) output from the XPS 9500
It's possible to get 4K@30Hz HDR (10-Bit) output from the XPS 9500
The in-box adapter is pretty limited and will not go above 4K@30Hz
Using an adapter with USB Hub will halve the Display Refresh Speed (reported here). If you want 4K@60Hz an adapter with only HDMI/DP should be used.

I ran all these tests by connecting the adapters to the left side of the XPS 9500. I’ll probably try the right one later.

Thanks for this man! I was using the included dongle and couldn't figure out why it wouldn't let me enable HDR. I then bought another dongle off amazon (https://www.amazon.com/gp/product/B075V68NVR/) that didn't work. Didn't even support 60hz. Finally went with the startech one and it worked right off the bat.

Hey y'all,

Looking for feedback if what I'm planning is doable. Picture attached.

2 2k monitors running at 144Hz: 1 is primary larger landscape monitor and 2 is secondary portrait monitor. Switching source using primary monitor.
High speed data transfer between 1,2,3 when either using 1 or 2. What cables would be required? Any caveats? Initial thoughts are connecting both 2 and 3 to back of doc using USB C cables to the TB 4 ports

You can not connect gaming PC to WD22TB4 via dp1.4. The display port on your gaming PC and the dock are both outputs.
You can achieve two 2K @ 100Hz or 120Hz at the max. 144Hz is not possible. For this, you need to

2a. Connect 1st monitor to either DP1 or DP2 or HDMI or USB type C.

2b. Connect 2nd monitor to TB port on the far right.

We’ve just received two SD25 units for testing. Due to their remote management functionality, they appear on our network with their own MAC addresses, when no device is connected. This behavior is unwanted in our environment, as it could interfere with our network access control policies.

Additionally, the docks attempt to obtain an IP address via DHCP and try to connect to the Dell Cloud.

Does anyone know if there is a way to completely disable the cloud functionality?

We could go with the WD25, but it only supports 100W Power Delivery, which is too low for some mobile workstations.

After placing the order, we received an invitation to the Dell Device Management Console. This platform allows onboarding of the devices and deployment of policies, for example, to disable USB ports. However, there doesn’t seem to be an option to disable remote management (you could disable the Ethernet Port, but I guess it would be unusable then).

Apparently, the docks also have built-in Wi-Fi and can be connected to wireless networks via policy settings.

I contacted Dell support regarding this issue, but they told me that disabling remote management is not possible.

How did you get the full power out of yours? Any Dell laptop I plug mine into gets the low power warning. We got 2 SD25TB5s for testing. I thought it was weird how they would somehow push the power that we had always needed the dual connection for on the WD19DCS unless they only work with the 2025+ Dells in that way?

We don't have the SD25TB5 for now. Just the WD25 and SD25.
If it's just one cable, I assume the laptop needs to support the higher wattage for charging (Dell Mobile Workstation Pro Max Plus/Premium).
Which laptop do you want to connect?

Did you have to jump through a bunch of portals to get this connected to intune ? Our company is looking at these and it seems that you have to run software on the local machine to get it to enroll, seems very odd.

I dont know if you can connect these Docks to MS Intune. But for the Dell Cloud, it seems that you have to enroll policys in the Dell Cloud Portal and set a Option in the DHCP Server so the Docks will get the URL to connect to.

I miss a option to disable the standalone network connectivity of these docks. Currently, i am waiting for a reply from our Dell Sales Person but i guess there wont be an option to do this.
