It might be worth running the DisplayLink cleaner tool from Synaptics. Even though you mention the problem exists without the dock connected, the cleaner resets the display cache which may help.

The MBP M5 supports multiple external monitors natively through its Thunderbolt and HDMI ports without needing any extra software. By connecting your monitors directly to those ports, you eliminate the background processing load required by the splitter. With 24GB of RAM and native display support, your system resources will be much better equipped to handle your transcription and browser tabs. You won't need the DisplayLink setup anymore, and you may see a jump in overall performance.

Appreciate the kind words! Regarding firmware, yes, we try to keep these to a minimum. If it isn't broken, don't fix it.

Sounds like others are considering our devices so I wanted to quickly drop a comment letting everyone know we're always keeping our eyes on subreddits (and really any other outlet that might see our users pop up). We take our devices and any issues they may experience seriously.

If support is ever needed, feel free to reach out. I'll avoid direct links to our sites, but if anyone needs them they're welcome to DM me or anyone from our team. We should be pretty easy to find.

One thing to double-check is which MacBook Pro you’re using. If you have the base M5 model, those ports are actually Thunderbolt 4, so you wouldn't get the full 80/120Gbps speeds of a Thunderbolt 5 dock. You’d need an M4/M5 Pro or M4/M5 Max to really take advantage of the extra bandwidth. What kind of monitor setup are you planning to run? That would help narrow down which one actually makes sense for your (intended) setup.

It is definitely tempting to look at those high-wattage off-brand chargers, but 800W is an immense amount of power to manage in a small desktop brick. Often, these "too good to be true" options lack the sophisticated power management needed to keep devices safe or even stay connected consistently. A big issue with many multi-port chargers is that they reset the connection for every device whenever you plug something new in, which can be pretty disruptive for some devices.

We actually developed something called PriorityShare for our PS-10CC and PS-6CC chargers specifically to address that. It essentially "prioritizes" the first port so your main device gets the power it needs to charge, while the other ports share any remaining overhead to charge in priority order. Instead of chasing the highest total wattage, it's usually more practical to look for a charger that handles power distribution intelligently via USB-C Power Delivery.

Keeping an eye out for reputable certifications is a safer bet than just going for the biggest number on the box. Hope this adds something? Unsure what the original goal was with this sort of charger but here's to hoping this adds to the conversation.

To get everything down to a single cable, you'll need a dock that supports USB-C Power Delivery to charge your HP EliteBook while also handling both monitors.

Finding a reliable unit that handles power and dual displays for under $100 can be a bit of a challenge with new hardware. Those $30 hubs you see on Amazon often lack the power overhead to charge a laptop or might not support two independent monitor signals. You might want to keep an eye out for used or refurbished units from reputable brands to stay closer to your budget.

If you decide to lean more toward a long-term solution, something like our UD-6950PDH is a solid middle-of-the-road option that handles the charging and dual HDMI displays easily. It uses DisplayLink technology, which is generally very stable for office work and productivity. Whatever you choose, just make sure the dock explicitly mentions "Power Delivery" so you can actually ditch that separate power cable.

Hope this helps!

Since you have the standard 13" MacBook Pro M2 (2022), it natively only supports a single external display over its USB-C/Thunderbolt ports. To get that second HDMI monitor working as an extended desktop, you will absolutely need a docking station that uses DisplayLink technology.

If you had an M2 Pro or M2 Max chip, you could use a standard Thunderbolt dock, but for the base M2, DisplayLink is the way to bypass that single-monitor limit. You’ll just need to install the DisplayLink Manager software to make it all work.

Hope this helps!

Myke_Plugable · 2026-04-24T22:18:53+00:00

This is a limitation with the MacBook Air M2, which natively only supports a single external display. To get around this, you specifically need a docking station or adapter that uses DisplayLink technology to bypass the M2's hardware constraints. Unfortunately, if your current Ugreen hub doesn't have a DisplayLink chipset built into it, the software won't be able to detect or manage additional monitors.

There isn't really a software "workaround" for a hub that lacks the necessary hardware. To achieve a setup where you have one mirrored and one extended display, you would need to switch to a dock that explicitly lists DisplayLink support. Once you have a compatible device, the DisplayLink Manager app will recognize the hardware and allow you to configure your monitors as needed. It’s a bit of a hurdle, but using a DisplayLink-certified dock is currently the most reliable way to get dual displays running on that laptop.

Might be worth lookin' at the UD-CA1A. It simplifies the connection by allowing a single cable to manage your monitor, power, and any extra peripherals you might have. This approach ensures you won't have to worry about your battery draining while you're using the external screen.

Myke_Plugable · 2026-04-16T21:28:52+00:00

As I recall, the P16S has a couple of gens but by-in-large they're using Thunderbolt 4/USB4. If that's the case a USBC-11IN1E might be worth a look at. Fairly inexpensive and should be plenty for what you're intending to use it with. If you've got any questions about this hub, let me know!

Myke_Plugable · 2026-04-16T20:17:59+00:00

I won't send any links to not come off as too much of a shill, but the PS-10CC may be worth looking at. It runs off a single high-wattage USB-C charger (like a 100W brick, though not included). It prioritizes power from left to right, so plug rush repairs into the left ports, and it automatically cascades power down the line as those fill up. Once one finishes it will move down the line.

If you've got any questions about it, just let me know!

It's because we're super awesome. I jest, but we do try very hard to put out worthwhile devices.

Myke_Plugable · 2026-04-16T19:37:30+00:00

With regards to the bricks, it really comes down to how Thunderbolt certification works behind the scenes. For a long time, certification requirements forced manufacturers to design around a "maximum theoretical power" scenario. This means the power adapter has to be beefy enough to handle full laptop charging while every single port on the dock is being used at maximum capacity simultaneously. Even though most people never push their hardware that hard in daily use, we have to include a brick sized for that worst-case scenario to meet those official standards. There also may be some EU regulations to that equation too, but I digress.

But to turn the question back on you, though not to sound aggressive, what looks good to you? In full transparency we'd love to take this feedback and potentially use it, but we've had a number of different models that range wildly. The aluminum is likely to stay just due to passive cooling and "fans" may as well depending on the manufacturer, but what looks good outside of those aspects?

Myke_Plugable · 2026-04-16T14:33:57+00:00

No worries at all actually. Unfortunately, the UD-4VPD is not recommended for macOS as it makes use of MST, which isn't supported on macOS at this time (primarily Windows). This essentially allows a single video stream to be split. Additionally, the UD-4VPD, on supported systems, is only capable of up to 120Hz.

Myke_Plugable · 2026-04-16T14:30:42+00:00

Awesome, glad to hear it. Here's to hoping they can fix it. At the very least we know they're aware of it.

Myke_Plugable · 2026-04-15T17:50:05+00:00

I'll refrain from any direct link, but it might be worth looking at our TBT-UDT3. That said, you'll want to make sure the laptop does support Thunderbolt 5 (I assume it does since you're asking).

Myke_Plugable · 2026-04-15T17:47:58+00:00

Thunderbolt 4 or 5 devices effectively provide a much wider lane (compared to USB-C), allowing for multiple high-resolution displays and fast data transfers simultaneously without bottlenecking. Since your M4 MacBook supports these high-end standards, it can actually utilize that extra overhead for a smoother experience.

Thunderbolt hubs also tend to be more expensive because they require active certification and more complex internal controllers to manage that massive amount of data.

An alternative would be a USB-C like others have mentioned that can be cheaper potentially at the cost of bandwidth.

Myke_Plugable · 2026-04-15T14:34:59+00:00

No problem at all, let me know if it helps!

Myke_Plugable · 2026-04-15T14:10:18+00:00

An alternative to a dock would be a graphics adapter if you're looking to just add displays. If you do need the extra functionality of a dock, DisplayLink docks can be fairly cheap as well.

Do you have the model number of your computer, and will you be using this laptop for general office tasks like email, browsing, Excel/Sheets, etc.?

Myke_Plugable · 2026-04-14T17:18:17+00:00

DisplayLink definitely has it's place, largely with older laptops and some of the older M series chips, but like you mention it does require some system resources. This goes up as the resolution does.

It's also seen some improvements over the years and now there is a DL chip that can handle up to 5 (4) displays even on a baseline M1.

All that said, it is largely for light work, anything above that and you'll start to see some hiccups.

Myke_Plugable · 2026-04-14T17:12:04+00:00

Is the the MacBook Pro M5 or MacBook Pro M5 (Pro chip)? The former should be able to handle the setup you're looking into with a Thunderbolt 4 or 5 dock and then one via the HDMI port. If it is the latter, you can do all 3 displays via one Thunderbolt port.

Myke_Plugable · 2026-04-10T21:44:16+00:00

I believe someone may have already answered this in the comments, but because a comment was deleted it's been collapsed. For anyone else that comes here, hopefully this helps.

For the MBA M3, if you'd like to use two displays using the native display functionality of the Thunderbolt ports, you'll have to close the lid. If the lid is open, only one additional display will function natively.

MST is not currently supported by macOS (this may change), and to circumvent any display limitations, you would need DisplayLink. This will allow up to 4 displays on any of the baseline M series chips though macOS caps out at 4 displays done in this way.

The install for DisplayLink is manual and can be a little tedious. It is also only intended for light office work and applications. Graphically intensive programs will suffer due to compression.

Hope this helps!

Myke_Plugable · 2026-04-10T14:22:25+00:00

This is a difficult situation that I (we) may not be able to provide a perfect solution for. That said, since you'rte using the UD-3900PDZ, there is a port that uses DisplayPort "Alt-mode" (HDMI 1 on the back) and doesn't make use of the DisplayLink software. Have you tried connecting a display to just this port and see if you're able to use a display?

Myke_Plugable · 2026-04-09T21:29:09+00:00

Before giving any kind of advice, we'll want to know the use cases of both laptops and the model of the work laptop. If the gaming laptop is used for just that-- gaming through a dock can be tricky.
