Yes, you will need a laptop to push a signal to the dock and connected monitors.

Glad it worked!

If you are referencing responsiveness from mouse movement or keyboard actions, the speed is the same as if you were working on your laptop itself. Although, since this this walkthrough was made, we have been using the WD22TB4 dock in the field these days...update video coming soon!

As long as the Insprion 5502/5509 has a USB-C port then you should be able to use this dock. Unfortunately, according to a Dell forum post, it seems you may not be able to run the 3 monitors: www.dell.com/community/en/conversations/latitude/connect-3-monitors-to-wd19tb-dock/647f8e1bf4ccf8a8deee0d84 Additionally, being able to push to 3 monitors will also depend on if your Inspiron specs can handle it. As a non-dock workaround you may want to look into whether or not you can daisy chain the Samsung monitors together. Dell has some monitors with this capability so the technology is out there; however, beyond 2 monitors, you will be compromising on the resolutions you will be able to achieve. Ultimately, the more monitors you have the lower your resolution will be (also dependent on your laptop specs): www.dell.com/support/contents/en-us/videos/videoplayer/monitor-daisy-chaining/6335488088112

Yes! The dock will/should charge your MacBook through the USB-C connection cable without needing to connect your MacBook's power adapter. When the dock's USB-C is connected you should see the charge icon on the battery.

Looking around some forums, I haven't seen a usb-c to thunderbolt adapter available, where I feel like this dock would not be a good fit. BUT the HDMI to Thunderbolt 2 adapters are still available, where you could use that for a single external monitor, then use a USB dongle for one or both of the USB 3 ports to increase your number of USB ports available. It's not a clean solution, but it might help you get some more mileage on your 2015 MacBook. In general, if an older laptop still meets your needs then keep using it as long as you can. I think ppl are usually pushed to upgrade if apps they use no longer work with older laptops...but usually basic web browsing or checking email should be doable.

​@@sculawtechs Thank you for your reply. My laptop works great still and meets my needs just fine but I would consider buying a new one if buying a new dock and/or adapter cables starts to become too complicated and costly. The first part of your response is what I am currently using. It's a HP screen with a HDMI cable, connected to a HDMI to Thunderbolt 2/mini display adapter, which plugs into my thunderbolt 2 port. This works great. The problem is the two additional screens I would like to connect which are Acer and have DP cables. Am I following you correctly when I think you're saying to purchase a USB-A dongle to plug into my laptop and then look for DP to USB-A (or is it USB-A to DP?) adapter to plug the screens into the dongle? I'm finding the dongles for $10-20 and the adapters for $60-80 each. Am I on the right track? Would something like this work as well? www.amazon.com/Plugable-DisplayPort-Monitor-Ethernet-Compatible/dp/B08F2TSR43/ref=sr_1_12_sspa?crid=2F3PT9CGAFFEI&dib=eyJ2IjoiMSJ9.S_gNXdXOyw6XzUUZcFtOZewTK3PDVGorqnOFOclwFcZbH72OhpPaCZ51Wra2Eu7kLqHDAdVue-0eREaGBTLBPbBKZxsEXSzq-nVN_gA4wQ8l5c6t8dRqQn08u7CH47NoGHHUQ45kU2FVeQtpJfWT1gHwpK9uod0TQyPe3-pJcZtdJKI3a2FkZsnFrxpKF3XSnMZ370tSpELNcNU8VKwENkFGh7a7TTDk0S4WA877-8Ur8CjaAi74oN8Q1V43iKECDXIe3IzNnGe-fUdO9z8ztQDTHAcB-zlarEy8qE82Va4.PUcpCqXkwHXHl7LAw8WyIT1zf14OAbGMC01i3JC7tEA&dib_tag=se&keywords=Display+port+to+USB-A+Adapter&qid=1719855820&s=electronics&sprefix=display+port+to+usb-a+adapter%2Celectronics%2C585&sr=1-12-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY&psc=1 Thanks again for your help! Tech is not my forte but I'm trying.

Would it be a possibility to Daisy Chain the screens to each other? Again, not tech savy, so forgive me if these are rudimentary questions. Just googling for options.

@@jenniferbijl6371 No worries! Something like the Plugable dock would be an alternative. One thing about the Plugable docks is that they use an app called DisplayLink for pushing an image to multiple displays. I also saw some DisplayPort to USB-A adapters on Amazon, so in theory those should also work.

@@jenniferbijl6371 Daisy chaining seems also be an option, but it will depend if your monitor supports that feature. For example, on some of the newer Dell monitors, there are DisplayPort 'in' ports in addition to a 'DP Out' port, where you could use that to daisy chain. Your monitors should have a manual online where you can do a word search to see if it has that feature. Cheers!

As far as we have seen, these docks have only supported 2 monitors, however we have some users who use it with an open laptop providing a smaller 3rd screen.

Negative! It will work with monitor with DisplayPort or HDMI ports. For a time we had some ppl with older monitors having DVI or VGA ports and were able to connect to these docks with a DVI to DisplayPort adapter.

@@sculawtechs oh so it can work on other monitors than dell?

@@nasersim8 Yes that is correct, just make sure the monitor has DisplayPort or HDMI ports!

@@sculawtechs oh thank you very much

Ha 😂 On Reddit I some folks mention "SentinelSweeper" which should remove it not needing passwords/additional admin access. Maybe give that a try or let us know if it's worth making a video on.

@@sculawtechs it looks like the new version is Sentinel Cleaner. But you have to call them to get help with it, and they won’t help you unless you have an account.

Yes! The power button on the dock does light up with pressed to power on a connected laptop. We are now using the Dell WD22TB4, so we'll be sure to include a note about that for the updated video.

Sorry about that and thanks for the note! The connection from the dock to the laptop is USB-C. Thankfully the majority of docks utilize USB-C to connect to laptops, creating a bit of standardization between for Windows and Apple models.

@@sculawtechs hi! If my PC doesn´t have a USB C port will this work if I use a USB C female to USB 3.0 male adapter? Currently struggling with setting up the unit and I have a feeling it might just not be compatible? Thanks in advance!

@@danielnvrt We haven't tested a USB-C to USB-A adapter on a laptop w/o any USB-C ports, but I don't think that would work due to the data transfer/power limitations with the USB 3.0 connection.

Glad to hear it!

Here they only deploy Latitude and Precision models, so we haven't been able to try the XPS line. Latitude is ok for basic apps/tasks, Word/Excel/PowerPoint/PDFs. The newer Precisions have a hardware bump and have been able to decrease their footprint. We haven't tried the M2 Mac Mini either, but we do have some M1 MacBook Airs and M2 MacBook Pros and there is a noticeable difference in performance vs the Dells. One downside for the M1 MacBook Airs and the Dell/Plugable docks is that they no longer push to dual displays. From what I've seen on the forums, this is due to an issue on Apple's side which I'm hoping changes soon.

Possibly, but I feel like there are a limited amount of USB ports, so depending on how many external devices you have it may not be the best option.

With the WD19TBS you would not be able to use dual '27e22h' monitors because they only have 1 HDMI and 1 VGA port. On the other hand, if you already have the monitors and the dock, a workaround would be to purchase an "HDMI to DisplayPort" adapter (around $10 US).

The dock power supply is necessary to power the dock itself and provide power to the connected laptop, and the dock will not function/push a signal to connected monitors without it.

Yes! If the laptop is shutdown or asleep, the power button on the dock should power on the laptop or wake it from sleep mode.

From our testing/use cases, we have never connected 2 computers to the dock, but in our experiences this dock does not function as a kvm switch if that is what you are looking for.

You can try running any firmware updates from the 'Dell Command Update' app, however, checking Dell's Dock compatibility list I'm not seeing the 5515 being compatible with the WD19DC: www.delltechnologies.com/asset/en-au/products/electronics-and-accessories/technical-support/dell_docking_compatibility_guide.pdf

grimace backstory

No duh.it’s a meme smart ass

Hi John, unfortunately on this specific dell dock there is only one HDMI port, so if your monitors only have HDMI inputs, then you would need an HDMI to DisplayPort or HDMI cable or adapter. We have started receiving the Dell WD22TB4 which also has a miniDisplayPort/USB-C option as well, which I have also seen more often on newer monitors.

Thanks for your questions Sagar! I'll we don't have the 2721DS monitor in our inventory, but I'll see if I can find something similar to test that out.

The USB cable is for the 4 additional USB ports built into the monitor. Since there are a limited amount of ports on the dock itself, I've been using the ports on the monitor to offset.

@@sculawtechs thanks for the response,

Our standard monitors are pretty basic, so I haven't tested with any FHD/75hz monitors. We'd need to check on Dell's site for the dock's manual to confirm...

You are welcome, good luck on your exams!

TLDR: Avoid Dell's WD19TBS if you are running multiple displays with a MacBook! We have noticed issues with this dock and multi-displays on MacBooks, where it only pushes a single image to both screens. Instead we have been using the HyperDrive M1/M2 MacBook USB-C hubs as an alternative.

Glad it helped!
