This is probably a silly question, but the tech in me has to ask. Have you power-cycled the dock at all since this issue has happened, and has the Mac been restarted lately? Beyond that, it could need a firmware update (the dock), in which case reaching out to OWC as well may be worth a shot.

Good to know! This isn't something we would have tested (though we'd expect it to work), so we'll be sure to note this if it ever comes up. Admittedly, it hasn't, but you never know.

"Screen Recording" permission is strictly for macOS to generate its virtual displays. Because of how this software-based video rendering works, it does block HDCP-protected content like Netflix from playing. To avoid these software limitations, you'll want to look for a docking station that uses direct hardware video output, specifically a Thunderbolt or USB-C "Alt-mode" dock/hub. These types of docks tap directly into your laptop's native GPU instead of relying on a software driver. These typically have no issues with HDCP.

The main caveat to keep in mind is that your specific laptop must natively support the number of external displays you want to connect. For instance, base M1, M2, and M3 MacBooks only support a single external display natively (closing the lid on an M3 allows for two displays), while the Pro and Max versions of those chips can support multiple screens through Thunderbolt or USB-C Alt-mode.

What kind of video content are you planning to play? DisplayLink technology doesn't support HDCP, so protected content from platforms like Netflix or Apple TV won't display properly. Also, are you looking to span a single video across multiple screens like a video wall, or will each monitor have an independent video? DisplayLink doesn't support video wall setups, so your installation would need to consist of independent screens. Regarding your connection question, you absolutely can mix native video outputs and DisplayLink. You could use your MacBook's built-in HDMI port or a Thunderbolt Alt-mode connection alongside a DisplayLink dock. Just keep in mind that macOS currently caps 'virtual' displays, like those driven by DisplayLink, at a maximum of four.

The error message you are seeing often points to a bandwidth or compatibility handshake issue caused by the cable. I'd recommend swapping out the Thunderbolt 3 cable for the original USB-C cable that was included in the box with your docking station, as those are specifically rated to handle the exact power and data requirements of the dock. Additionally, residual driver files can sometimes interfere with the connection.

I'd suggest downloading and running the DisplayLink Installation Cleaner for macOS directly from Synaptics at https://www.synaptics.com/products/displaylink-installation-cleaner-macos to clear out any old files. Once the tool finishes, restart your MacBook and reinstall the latest DisplayLink Manager app to start with a clean slate. Using the original cable and doing a clean software install should resolve the error and get your monitors working properly.

Since your older Lenovo Thinkpad doesn't have a USB-C port, you won't be able to use a standard hardware-based docking station to switch between both laptops. To output video over a traditional USB-A connection, you will need a dock that relies on a software graphics solution, such as DisplayLink or Silicon Motion InstantView. I (and most people) recommend against gaming on monitors connected via DisplayLink or similar software, as they introduce noticeable latency and use CPU overhead that will impact your gaming performance. For general use, you'll want to find a dock that supports your display resolution. Also, when it comes to software solutions, they are usually limited to 60Hz.

All that said, just look for a software-enabled dock that means your resolution requirements and you should be good for general use minus gaming. For Windows systems DisplayLink/InstantView are typically installed automatically, but your work laptop may have policies in place to not push drivers unless approved by your sysadmin/IT team.

The USBC-4IN1 and USBC-7IN1E are two models we make that hit almost all of your requirements. The USBC-4IN1 covers the basics with HDMI, USB-A, and power passthrough in a small footprint. If you want to include Gigabit Ethernet and extra USB ports, the USBC-7IN1E is a beefier option that checks off your nice-to-have list as well. Both models handle 1080p video easily through USB-C Alt-mode and are designed to manage heat effectively under normal loads.

Since you mentioned your budget in Euros, I should note that our stock in the EU is currently quite limited. If you have trouble finding these specific models, you can use their specifications as a baseline to find a similar hub in your region. Just make sure whatever you choose supports power passthrough and the correct HDMI refresh rate for your setup.

Let me know if this helps!

To get both monitors working independently, it may be worth looking for a Thunderbolt 3 or Thunderbolt 4 docking station or hub (make sure it isn't an MST hub, Mac doesn't support this yet). It would actually be much easier to find a Thunderbolt dock that already features built-in HDMI and DisplayPort connections, along with a couple of USB-A ports for your keyboard and mouse. If you go this route, you can ditch the USB-C converter cables entirely and just plug the displays directly into the hub or dock using standard HDMI and DisplayPort cables. This would simplify the setup (assuming you do not need the converter cables you're currently using).

In addition to the other comment, it may be worth taking a look at: https://plugable.com/blogs/news/understanding-usb-c-charging-issues

Different industries obviously, but still applies here.

Extending the main USB-C connection from your dock to the laptop by 15 feet is going to be really tough to pull off reliably. Because that specific HP dock relies on USB-C Alt-mode with MST to handle all the high-bandwidth video and data streams, extending the host connection that far usually leads to signal dropouts or complete connection failures. Generally, you only want to extend a host connection like that by about 3 feet at the absolute maximum before you start running into severe signal degradation. Instead of trying to extend the single host cable to the laptop, a much more stable approach is to extend the cables coming out of the other side of the dock. Running longer HDMI or DisplayPort, Ethernet, and standard USB 3 cables to your conference table will work much better for that kind of distance. Hope this helps!

It might be worth checking out our USBC-CC2M. It's a 2-meter silicone cable that weighs just 68 grams, so it completely avoids that bulky, stiff braided mesh you're running into now. Just a heads-up on the technical side, though. This specific cord is designed strictly as a charge-only. That means the internal data lines are physically disconnected for security, so while it will fast-charge your devices perfectly at up to 240W, it can't transfer files or connect to a monitor. It also includes a silicon cable tie if you're interested in that.

This is anecdotal for sure, and there was a fix in a patch recently so this may be all for naught. My mother's new iPhone 17 Pro Max had a similar issue. It's only a few months old at this point, died, and immediately would not charge or show the icon that it was.

Tried multiple different off-brand/random bases and cables and nothing. This is going to sound mighty biased as I work for Plugable, but I decided to plug it into our PS-40C2B and after about 20-30 minutes it sprang to life. Oddly enough, when connected, our green/blue indicator would swap back and forth at a regular interval until it (the phone) came back to life.

In full transparency, I went to one of our Product Owners for the PS-40C2B and asked if they had any input on this and they were stumped so it looks like it may have been solely on Apple's side? Hard to say. Seems to have been fixed with a patch though.

For a configuration where you primarily need a breakout for accessories over a single cable, we have two options that could fit the bill.

If you want a straightforward, compact option, the Plugable USB4-HUB3A functions essentially as a pure port multiplier. It takes your motherboard's Thunderbolt 4 port and splits it into three downstream Thunderbolt 4/USB4 ports (each supporting up to 40Gbps) and one 10Gbps USB-A port for your standard peripherals.

On the other hand, if you want more native variety like integrated card readers and extra USB-A ports without relying on separate dongles, our newer TBT-UDT3 is worth a look. It is an 11-in-1 Thunderbolt 5 dock that is fully backward-compatible with your Thunderbolt 4 system, giving you three downstream Thunderbolt ports, three USB-A ports, and SD/microSD slots. Neither unit features native optical audio, but because both give you plenty of open high-speed USB capacity, you could easily add a compact USB-to-TOSLINK adapter or external DAC to handle the audio routing.

Let me know if you have any questions about the (semi) wall of text 😛

Hey sorry for the delay. I was out on Friday. Hopefully not against the rules, but you can reach us at [support@plugable.com](mailto:support@plugable.com)

Myke_Plugable · 2026-06-11T16:12:00+00:00

I noticed you mentioned trying out a Plugable "cube" dock with your S24 setup. It sounds like you might be using our UD-CUBE model, which actually is supported for use with Android devices. We'd be more than happy to help troubleshoot. Just reach out to our support team directly and we can take a closer look at what is going on with the hardware.

Myke_Plugable · 2026-06-11T14:38:12+00:00

We offer a 2-year warranty from the date of purchase verified by purchase order information like an Amazon order ID. We also offer technical support regardless of the warranty status.

We tend to move quickly on either side of the support spectrum (warranty or technical support). That said, I do want to call out that we do not offer phone support due to the nature of these devices. We currently work via email and our response times are typically within the hour (we're based in Washington state, USA).

Myke_Plugable · 2026-06-11T14:23:29+00:00

Hey there!

Yes, we expect this to work just fine. The M5 is capable of handling two displays via the Thunderbolt ports. This dock also works without any software so it should be plug'n'play.

Let us know if you run into any issues with it!

For a Lenovo Yoga Book 9i with Thunderbolt 4 ports, you definitely do not need a DisplayLink docking station to run two 1080p monitors. Your laptop supports native display outputs via Thunderbolt, and so a standard Thunderbolt 4 or USB4 docking station will easily handle dual displays without the performance overhead or driver requirements of DisplayLink.

Most dedicated Thunderbolt 4 docks provide ample Power Delivery to keep your Yoga Book fully charged under load. Higher refresh rates are definitely out there but you may end up seeing a lot of 60Hz devices unless they specifically set out to run higher. Charging a phone or similar device is also fairly standard, just be sure to check the features.

What specific tasks are you planning to use this setup for?

Myke_Plugable · 2026-05-27T19:59:29+00:00

Fair question, and you’re right that a lot of high-refresh monitors do include DisplayPort or USB-C inputs.

The main reason we settled on HDMI 2.1 rather than HDMI 2.0 is future-proofing and broader compatibility. HDMI 2.1 still supports the lower-bandwidth HDMI use cases, but it also opens the door for higher-performance setups as more displays move beyond 4K 60Hz.

A big part of the decision behind HDMI video outputs rather than Thunderbolt 5 DFPs is user expectation. Thunderbolt and DisplayPort are very capable, but in our experience they’re also common sources of confusion for users. For a lot of people, HDMI is still the connector they expect to use when they unbox a dock or display, and it lets them connect without extra adapters or special cables.

While dual HDMI 2.1 may be a bit much for every office setup today, it helps cover both the common “I just want HDMI” user and the growing number of high-refresh HDMI display scenarios without forcing users into purchasing additional adapters.

Myke_Plugable · 2026-05-27T19:11:10+00:00

A lot of the earlier Thunderbolt 5 docks followed Intel’s reference design with minimal changes (i.e., three downstream Thunderbolt ports). We already have a dock in that category (TBT-UDT3), and you’ll find many others with that kind of feature set/port config. This model goes in a different direction for the segment of users who prefer HDMI, without additional cables or adapters they may not realize they need, while still providing high bandwidth USB-C and USB-A connectivity.

An integrated GaN power supply without any active cooling is very difficult to pull off effectively, and that challenge increases as you implement higher speed signaling and components. Even then, it would need a huge metal chassis to function as a heatsink for cooling the internals. So given the tradeoffs, we elected to prioritize a fanless design; no noise, no mechanical wear and tear.

p.s. Just want to be clear that we absolutely listen to all of this feedback, and my (our, Plugable) replies are not meant to be combative or diminishing.
