How to use two or more monitors to M1, M2, M3 or M4 MacBooks
While the higher-end MacBooks with M1/M2/M3/M4 Pro and Max chips support multiple external displays, Apple’s lower-end range of MacBooks that use a standard M1 and M2 processor cannot natively connect more than one external monitor, and to do so the M3 has to have its lid closed. This is a massive limitation compared to the previous Intel-based generation of Mac laptops that could run two displays when connected to a USB-C or Thunderbolt docking station or hub.
Apple’s M3 MacBook Air models support two external monitors but only if the MacBook has its lid closed in what is known as Clamshell Mode. The M3 MacBook Pro supports a similar feature, but the macOS Sonoma 14.6 update needs to be installed. We explain how to run dual external displays on an M3 MacBook in a separate article.
The solutions below, however, allow for more than two external displays on plain M1, M2 and M3 Macs with their lids open if you want it. The plain M4 MacBook Air and Pro models do natively support two displays with the lid open but if you want three displays for these MacBooks, then keep reading.
There have also been reports that the M3 MacBook Air with lid closed suffers significant performance decline due to heat build up, so following our advice below still has relevance even for M3 MacBook Air and Pro users who want to hook up to multiple displays and keep their Mac purring at full speed.
Later, we list our tested and recommended software and hardware solutions for adding more than one display to the plain M1, M2 and M3 Macs. You can jump straight to our list of the best DisplayLink docks if you know all about DisplayLink. If not, read on a while.
The solutions we explain here will also help plain M4 users and M2/M3/M4 Pro MacBook users extend to three external displays.
Here are the external display specs for Apple’s current laptops:
- M1 MacBook Air: Maximum one external display—read our workarounds below.
- M2 MacBook Air: Maximum one external display—read our workarounds below.
- M3 MacBook Air: Maximum two external displays if MacBook lid is closed. Three using our workarounds.
- M2 MacBook Pro: Maximum one external display—read our workarounds below.
- M2 Pro MacBook Pro: Maximum two external displays. Four using our workarounds.
- M2 Max MacBook Pro: Maximum four external displays.
- M3 MacBook Air: Maximum two external displays if MacBook lid is closed. Two or three with lid closed using our workarounds.
- M3 MacBook Pro: Maximum two external displays if MacBook lid is closed. Two or three with lid closed using our workarounds.
- M3 Pro MacBook Pro: Maximum two external displays. Four using our workarounds.
- M3 Max MacBook Pro: Maximum four external displays. Workarounds allow four using just one laptop port, plus dock.
- M4 MacBook Air: Maximum two external displays. Three using our workarounds.
- M4 MacBook Pro: Maximum two external displays. Three using our workarounds.
- M4 Pro MacBook Pro: Maximum two external displays. Four using our workarounds.
- M4 Max MacBook Pro: Maximum four external displays. Workarounds allow four using just one laptop port, plus dock.
However, there are ways around these plain M1/M2/M3 limitations, allowing you to run two or more external displays off your MacBook, which we will outline here. In each case, there’s a software download and a docking station, hub or adapter required.
The simplest solution is to get a USB graphics-enabled docking station or hub, sometimes called a DisplayLink Dock—and we’ve reviewed the best ones later in this article. USB graphics is a software-based technology (DisplayLink or InstantView) that compresses the video signals from the computer to the monitor, enabling you to connect multiple external displays to your M1, M2 or M3 MacBook.
Installing third-party software drivers leads to a slight risk that these might later be unsupported by future updates of the macOS, but the two drivers we recommend are recognized industry standards that we believe will continue to be supported and have been for a number of years already.
External displays: Big problem for M1, M2 and some M3 Macs
If your MacBook setup includes running more than one external display, you have a major problem: Apple’s basic (non-Pro or Max) M1 and M2 chips simply won’t allow it—at least natively. Apple states in the M1 or M2 MacBook Air and M3 MacBook Pro tech specs that they support only “one external display with up to 6K resolution at 60Hz”.
Foundry
While the M1 and M2 MacBooks natively support just one monitor, the M1 and M2 Mac Mini does natively support up to two external monitors—one via the HDMI port and a second via USB-C. But the M1 and M2 models of the MacBook Air and MacBook Pro (plus the M3 MacBook Pro) support only a single external display over Thunderbolt.
The M3 MacBook Air models (13- and 15-inch) were the first to support more than one external display—as long as you close the laptop’s lid (known as Clamshell Mode) to allow for the second external display. 14-inch M3 MacBook Pro has a similar limitation. The first display (allowing an open MacBook lid) has a maximum 6K resolution at 60Hz. The second display (requiring the closed lid) can be up to 5K at 60Hz.
The M4 MacBook Air and 14-inch M4 MacBook Pro escape the single-display limit even with its lid open, but if you want more than two displays for that model, you need a DisplayLink dock.
We cover the basics of how to connect your Mac to an external monitor.
Workaround: Install DisplayLink software drivers
You can use a combination of display technologies to get around the M1/M2/M3 MacBooks’ single-monitor limitation. DisplayLink is the most common software solution that you pair with a compatible dock, and SiliconMotion’s InstantView is another. Note that the docks need to state DisplayLink or InstantView compatibility—you can’t just install DisplayLink drivers and hope they work with regular docks and hubs. Here, we’ll refer to them all as DisplayLink docks for brevity.
Many multi-display docks use a combination of native USB-C Alternate Mode (native “Alt Mode” video output) and DisplayLink technology. This combination serves as a workaround to the M1/M2/M3 platform supporting only a single external display via USB-C.
Note that DisplayLink requires a third-party driver to be installed on the Mac. In general, setup is straightforward. Some of the docks we review below offer the DisplayLink software when you first connect the dock to your Mac.
The DisplayLink macOS app or DisplayLink Manager app are ways of enabling DisplayLink technology on macOS. The app is available as a standalone installer rather than through the mac App Store.
The initial InstantView setup is easier than DisplayLink with the hubs from Hyper and Satechi—but it suffers the same challenge that Apple’s software updates could disable it, which will entail installing a newer version and allowing the necessary security & privacy settings for screen recording, just as with DisplayLink.
You can download the latest version of InstantView software here. The latest version supports macOS 15 Sequoia, 14 Sonoma, 13 Ventura and 12 Monterey.
Neither software solution is complicated and both worked well in our tests as you can read below.
1. First, download the latest Mac DisplayLink driver. As stated above, some docks, do this for you but it’s always best to use the latest version.
DisplayLink Manager Graphics Connectivity App v. 13 is compatible with macOS Ventura 13, Sonoma 14 and Sequoia 15. For macOS Monterey 12, you need version 1.11; for Big Sur 11, look for version 1.9, and v1.5 for Catalina 10.15. It can be managed via the DisplayLink icon in the Apple Menu bar.
Here’s the one fiddly part: you need to enable “Screen Recording” to allow the DisplayLink Manager app to capture pixels and send them to your USB peripheral.
This can be found in System Preferences under Privacy in Security & Privacy; navigate to Screen Recording in the list on the left, then tick the Screen Recording permission for DisplayLink Manager after unlocking the padlock using your admin password. You may need to quit and restart DisplayLink Manager afterward. Don’t worry, DisplayLink isn’t recording your screen—this just lets it do its magic enabling multiple screens.
Installation is straightforward; take a look at the instructions here. Older versions did not support laptops’ closed-display/Clamshell Mode, but 1.8.1 and later do support Clamshell Mode if the MacBook is running macOS 11 or later.
There’s an option in DisplayLink manager to “launch at startup”, or you can drag the DisplayLink Manager to your Login Items in Users & Groups.
2. Then connect the MacBook to a DIsplayLink docking station—the dock must support DisplayLInk, as all the reviewed products listed below do.
3. For the first screen you can connect via the dock’s DisplayPort, HDMI or USB-C/Thunderbolt port, and this will be handled natively by the M1/M2 MacBook. If you need to, you can use a USB-C to HDMI or DisplayPort adapter.
The HDMI or DisplayPort output uses Alternate Mode (Alt Mode), and as it is basically a pipeline directly to the system’s native GPU, it will behave just like if you hooked up a USB-C to HDMI dongle to your laptop. This requires no user driver installation.
The second and third displays will rely on the DisplayLink software. DisplayLink uses an installed driver and the system CPU and GPU to convert graphics data on the system into data packets. That data is then sent over the cable as data packets and converted back to video information and output to the monitors via the DisplayLink chip in the docking station.
Which dock is best?
A docking station connects to your MacBook via Thunderbolt or USB-C. It then offers multiple ports that your laptop now has access to. These can include new display ports, such as HDMI, as well as Ethernet for wired Internet access, USB-C/Thunderbolt/USB-A ports at varying speeds, audio plugs, and card readers.
Learn more about the best Thunderbolt docking stations for more details, or you can connect via a simpler USB-C hub. Look for a dock with two or more display ports, preferably ones that can connect to your preferred displays without the need for an adapter.
Thunderbolt docks or hubs often have no dedicated display port but three available TB ports that can be used to connect directly to a USB-C display or via adapters to HDMI or DisplayPort monitors. While you may have to buy an adapter cable, 40-80Gbps Thunderbolt 4 or 5’s port flexibility and backward compatibility are recommended for users of modern Macs such as the M1 and M2 MacBooks.
USB-C docks and hubs are usually cheaper, but not always so check our reviews below.
Docking station and hub manufacturers are now actively marketing their products as solutions to the M1/M2/M3 external display limitation—docks have to support DisplayLink to work with the software. All the docks and hubs reviewed below require either the DisplayLink download or another similar software solution, such as InstantView, but no further hardware adapter except for the dock or hub itself. And of course, these hubs offer the usual multi-port benefits as well as the external monitor solution.
The best multiscreen hubs and adapters for M1, M2, M3 and M4 MacBooks
Below we have gathered the best dedicated hubs and docks for multiscreen M1/M2/M3/M4. Note that most of these listed (and tested) below use USB-C rather than Thunderbolt, so don’t benefit from the MacBook’s potential 40-80Gbps data bandwidth. If you require bandwidth higher than 10Gbps, go for a Thunderbolt dock and install DisplayLink as instructed above.
We have tested DisplayLink docks that can support four external displays and some that max out at two, which we expect will be plenty for most people.
Satechi Thunderbolt 4 Docking Station with DisplayLink – three 4K displays at 60Hz for M1/M2, four for M3/M4
Pros
- Supports up to four external displays at 4K 60Hz
- One display at 6K 60Hz
- 11 ports, inc. three 40Gbps Thunderbolt 4
- 2x HDMI 2.0 video ports
- Speedy SD card reader
- 96W charging and 180W power supply
- Connection: Thunderbolt 4
- Software: DisplayLink
- Max screens: 4
While plain M1 and M2 MacBooks are limited to three external displays using this dock when DisplayLink software is installed, M3/M4 and M1/M2/M3/M4 Pro/Max MacBooks can connect to four 4K at 60Hz.
Other docks reviewed here also allow M1 and M2 Macs to connect to three displays, but what we really like about the Satechi Thunderbolt 4 Docking Station with DisplayLink is right there in its name: it’s a full Thunderbolt 4 dock rather than USB-C. It therefore offers 40Gbps data-transfer rates compared to the 10Gbps that you’ll find on most of the other docks reviewed here. The Plugable TBT-6950PD, reviewed below, is very similar to this Satechi dock.
That Thunderbolt port connection also allows one of the three screens to be at 6K resolution (60Hz) while the other two via HDMI will be 4K at 60Hz.
There are two HDMI 2.0 ports plus a generous three downstream Thunderbolt 4 ports (as well as one upstream TB4 to the laptop). It doesn’t host any extra USB-C ports but the three Thunderbolt 4 ports (40Gbps data transfer, 15W power output) are backwards compatible with USB-C. There are two fast 10Gbps USB-A ports, too, plus a UHS-II SD card reader, Gigabit Ethernet and an audio jack.
Non-Pro/Max M3 and M4 Macs can connect to four displays using this dock, as long as the laptop’s lid is closed (clamshell mode). It’s also a great option for M1/M2/M3/M4 Pro users usually restricted to two external displays.
U.K. customers can buy direct from Satechi (with a small shipping fee) but will need to purchase a local power cable.
Satechi also sells a 12-port USB-C-based Triple 4K Display Docking Station that supports three 4K displays at 60Hz using DisplayLink. It is priced the same as the Satechi Thunderbolt DisplayLink Dock. Normally we’d always pick a Thunderbolt dock over USB-C but this one hosts a mix of DisplayPort and HDMI ports that offers a more flexible monitor choice than the Thunderbolt dock’s two HDMI and three TB4 ports. If you prefer DisplayPort for your monitor connection you should consider this USB-C dock although a simple USB-C to DisplayPort adapter will work the same magic on the TB dock.

WAVLINK USB-C DisplayLink (DL7400) Docking Station – four 4K displays at 60Hz for M1/M2/M3/M4
Pros
- Supports up to four external displays at 4K 60Hz
- 2x 8K at 60Hz display
- 2.5Gb Ethernet
- 30W USB-C
- 14 ports
- 2x HDMI 2.0 video ports
- Speedy SD card readers
- 100W charging and 160W power supply
- Connection: USB-C
- Software: DisplayLink
- Max screens: 4
While the Satechi and Plugable Thunderbolt DisplayLink docks support four displays for the M3 MacBook Air (while shut in Clamshell Mode), the M1 and M2 MacBooks are limited to three (one at 6K and two at 4K) using those docks. The Wavlink’s DL7400 chipset allows for even the M1 and M2 Macs to connect to four displays at impressive refresh rates: 1x 4K at 120Hz and 3x 4K at 60Hz.
As such, if you desire four displays to be hooked up to your M1 or M2 MacBook, the Wavlink dock is the better choice.
It might lack the Satechi and Plugable docks’ faster Thunderbolt connection but it beats them on network speeds with a 2.5Gb Etehrnet port—2.5 times faster if your network matches this (it’s backwards compatible with 1GbE).
The USB ports are at least 10Gbps and the SD and microSD card readers are also speedily rated at 312MBps.

WAVLINK USB-C DisplayLink (DL7400) Docking Station review
Alogic DX3 Triple 4K Display Universal Docking Station – three 4K displays at 60Hz
Pros
- Supports three external displays at 4K 60Hz
- 12 ports, inc. 10Gbps USB-C
- 3x DisplayPort 1.4 video ports
- Speedy SD and MicroSD card readers
- 100W charging and 135W power supply
- Connection: USB-C
- Software: DisplayLink
- Max screens: 3
This Alogic DisplayLink docking station supports up to three external 4K displays at an impressive 60Hz refresh rate and has an array of useful non-display ports. It can power the connected laptop at 100W and has a decent 135W external power supply so doesn’t require an extra USB-C charger.
The DisplayLink download link is clearly shown in the user manual, and instructions make sense—although you need a magnifying glass to read them!
The DX3 has three DisplayPort 1.4 ports but no HDMI, so you’ll need to add an adapter between dock and display if you prefer HDMI. As you’ll need to buy video cables anyway, this doesn’t matter as prices for straight cable and adapter cable are close enough.
This dock has two card readers: SD and MicroSD, both at top 312MBps UHS-II—allowing you to add inexpensive portable storage to your laptop setup.
It also has Gigabit Ethernet, four USB-A (one with 7.5W charging) and two 10Gbps USB-C (one 100W PD upstream to the laptop, and one 7.5W smaller device charging).
Reviewed below is Alogic’s DX2, which supports two 4K displays at 60Hz and lacks some of the other ports found on the DX3. if you just need two external monitors for your M1/M2/M3 MacBook this may be a cheaper option.
Wavlink Dual 4K DisplayPort & HDMI Adapter – two 5K displays at 60Hz
Pros
- Supports two external displays at 5K 60Hz
- 2x DisplayPort 1.4 video ports
- 2x HDMI 2.0 video ports
Cons
- No USB ports, Ethernet etc
- Connection: USB-C
- Software: DisplayLink
- Max screens: 2
This simple, portable and affordable adapter doesn’t give you loads of extra USB ports, Ethernet or card readers like a hub or docking station would, but it offers four powerful video ports: two DisplayPort 1.4 and two HDMI 2.0.
Once you’ve installed the DisplayLink drivers, this means an M1/M2/M3 MacBook can run two extended displays at up to 5K (5120-x-1440) at 60Hz using a combination of these video ports. You’d need to use both DisplayPort 1.4 ports for the maximum 5K resolution—the HDMI 2.0 ports max out at 4096-x-2160 at 60Hz.
There’s no passthrough charging so you’ll need to use another of the MacBook’s Thunderbolt ports to keep the laptop powered up in use.
Plugable USB-C Dual 4K Display Docking Station (UD-6950PDH) – two 4K displays at 60Hz
Pros
- Dual 4K monitor support for M1/M2/M3 Macs
- 13 ports
- 100W PD to laptop
- Fast SD card reader
Cons
- Not for fast data transfer
- North America only
- Connection: USB-C
- Software: DisplayLink
- Max screens: 2
If you don’t require full 40Gbps Thunderbolt, Plugable’s redesigned USB-C–based UD-6950PDH docking station plus free-to-download DisplayLink software can connect two extra 4K/60Hz displays to M1, M2 and M3 Macs. While plain M3 MacBooks can already connect to two external displays, this DisplayLink dock allows plain M3 MacBooks to remain open with the two additional displays attached (otherwise the M3 laptop’s lid has to be closed). M4 and M4 Pro MacBooks can already run two screens natively but using a dock saves the laptop’s built-in ports.
It features an impressive 13 ports including Gigabit Ethernet, SD and MicroSD card readers and five spare USB ports.
You won’t get data transfer any faster than 5Gbps so if you crave the full 40Gbps Thunderbolt bandwidth you should instead consider the more powerful Plugable Thunderbolt 4 Docking Station with DisplayLink, reviewed above.
You can use both of the dock’s HDMI ports or both DisplayPort or a mix of each, depending on your monitor requirements. Two video ports will always be left empty, but the flexibility is welcome.
No availability outside of North America has yet been announced.

Hyperdrive Dual 4K HDMI 10-in-1 USB-C Hub – one 4K display at 60Hz, one 4K display at 30Hz
Pros
- Supports two external displays at 4K
- 10 ports, inc. 5Gbps USB-C and USB-A
- 100W passthrough charging
- InstantView easier than DisplayLink
Cons
- Second 4K display is 30Hz rather than 60Hz
- Requires USB-C charger
- Connection: USB-C
- Software: InstantView
- Max screens: 2
The Hyperdrive Dual 4K HDMI 10-in-1 USB-C Hub doesn’t use DisplayLink and instead uses SiliconMotion’s InstantView.
Hyper says that it works “without having to download cumbersome drivers” but there is some software installation involved, and you need to allow InstantView access to your Privacy settings in System Preferences. You connect the hub or adapter to your M1/M2 MacBook and find the HyperDisplay app that appears in a Finder folder sidebar. Double-click the macOS InstantView icon and follow the System Preferences instructions. Once this has been completed your MacBook will automatically recognize the adapter from then on.
It’s an easier solution than DisplayLink but with the same ability to allow M1, M2 and M3 Macs to connect to multiple external displays.
This compact hub still includes 10 ports, including the all-important 2x HDMI. The first display at 60Hz is added via HDMI and DP Alt-mode and the second at 4K 30Hz through HDMI and InstantView.
Also included are Gigabit Ethernet, MicroSD card reader (UHS-I), 3.5mm audio jack, 2x 5Gbps USB-A, and one 5Gbps USB-C. A further USB-C PD port allows you to charge the connected laptop at up to 100W—handy as the hub itself uses up one of your laptop’s Thunderbolt ports.
Hyperdrive Dual 4K HDMI Adapter – one 4K display at 60Hz, one 4K display at 30Hz
Pros
- Supports two external displays at 4K
- 100W passthrough charging
- InstantView easier than DisplayLink
Cons
- Second 4K display is 30Hz rather than 60Hz
- Requires USB-C charger
- Connection: USB-C
- Software: InstantView
- Max screens: 2
This double-function hub is designed to provide two HDMI display ports for a MacBook M1/M2/M3, plus passthrough charging for the laptop. It doesn’t offer a bunch of other ports like its big brother, the Hyperdrive Dual 4K HDMI 10-in-1 USB-C Hub reviewed above. As a result, it is cheaper and is one of the most cost-effective solutions for adding multiple monitors to the limited plain M1/M2/M3 Macs.
Like the 10-in-1, it uses SiliconMotion’s InstantView rather than DisplayLink software to get past the limitation.
The first display at 60Hz is added via HDMI and DP Alt-mode and the second at 4K 30Hz through HDMI and InstantView.
If you require more ports, such as Gigabit Ethernet, card readers and USB ports, consider the Hyperdrive 10-in-1 or one of the other hubs or docks reviewed here..
Plugable USB-C to Quad HDMI Adapter (USBC-768H4) – four HD displays at 60Hz
Pros
- Supports four external displays
- InstantView easier than DisplayLink
Cons
- HD, not 4K
- Doesn’t charge your MacBook
- No card reader
- Connection: USB-C
- Software: InstantView
- Max screens: 2
Do you really need four screens? If you do, and you can do without 4K resolution, the Plugable USB-C to Quad HDMI Adapter supports four HD displays even on an M1, M2, M3 or M4 MacBook using the Silicon Motion InstantView software (requires download and installation).
The adapter features just the four HDMI ports so doesn’t offer any Gigabit Ethernet or extra USB-C ports, but does what it says on the box. All four displays can support HD (1920-x-1080) at 60Hz images.
The USB-C cable tucks neatly into the adapter’s case when not in use, making this a nimbly portable solution… as long as you don’t also carry the four screens around with you.

Alogic DV4 Universal Quad Display Docking Station – one 4K display at 60Hz, two HD displays
Pros
- Supports three external displays, one at 4K 60Hz
- 14 ports, inc. 5Gbps USB-C and USB-A
- 3x HDMI 2.0 and 1x DisplayPort 1.4 video ports
- 12W USB-C charging
- 85W PD charging
Cons
- 2 displays at HD, not 4K
- Requires USB-C charger
- Connection: USB-C
- Software: DisplayLink
- Max screens: 2
With third-party DisplayLink drivers, this dock will support up to three displays on a Mac. You can connect one 4K at 60Hz display (3840×2160 pixels) via either the DisplayPort or one of the HDMI ports. The other two displays via HDMI, however, are at a lesser HD (1920×1080) resolution, both at 60Hz.
There is a link to the DisplayLink download printed in the user manual, although the type in the manual is the smallest we’ve ever seen!
The specs aren’t quite as impressive as the Satechi Triple 4K Display Docking Station, with 5Gbps a maximum data-transfer rate, although charging wattage for USB-A (3.0) is up to 7.5W each and USB-C is up to 12W, which beats the Satechi..
However, it does boast both SD and MicroSD card readers for affordable portable storage options, although UHS-I rather than super-fast UHS-II. And, crucially, it’s cheaper, although you will need to add your own USB-C 100W PD charger, unlike the Satechi Triple 4K Dock.
Pros
- Supports two external displays at 4K
- 6 ports, inc. 5Gbps USB-C and 2x 5Gbps USB-A
Cons
- Second 4K display is 30Hz rather than 60Hz
- Requires USB-C charger
- No card reader
- Connection: USB-C
- Software: InstantView

The Satechi USB-C Multimedia M1 Adapter uses InstantView rather than DisplayLink but the installation process is practically the same when you follow the manual.
It includes 2x HDMI ports: one of which can support a 4K display at 60Hz and the other at 30Hz.
It’s more than a mere display adapter, though, as it also boasts USB-C PD passthrough charging at up to 85W, one 5Gbps USB-C port, and two 5Gbps USB-A ports.
Although named after the M1 processor it is fixing on the multiple display front, it will also work with similarly limited M2 and M3 MacBooks.
Alogic Dual 4K Universal Compact Docking Station – two 4K displays at 60Hz
Pros
- Supports two external displays at 4K 60Hz
- 7 ports, inc. 10Gbps USB-C and USB-A
- HDMI and DisplayPort versions
- Connection: USB-C
- Software: DisplayLink
- Max screens: 2
The Alogic Dual 4K Universal Compact Docking Station comes in two models—the CH2, which features two HDMI 2.0 ports; and the CD2, with two DisplayPort ports—so you can choose which best suits the external displays you already own.
Two external screens are probably enough for most people. If you require three, see the other hubs and docks reviewed here. Both screens can be up to 4K at 60Hz. Basic instructions are given on installing the DisplayLink software for M1, M2 and M3 Macs.
This neat, compact dock doesn’t feature as many ports as others mentioned here but what it has are top-rated: both the USB-A and USB-C ports support 10Gbps data transfer. There is also a Gigabit Ethernet port and a UHS-II SD card reader.
A passthrough USB-C port—you need to add a suitably powerful charger—can handle 100W, although 22W is required by the dock so leaving 78W for laptop and device charging. The dock must be connected to the laptop to allow device charging.
Pros
- Supports three external displays (2x 4K; 1x HD)
- VGA if you need it
- 12 ports, inc 4x 5Gbps USB-A
Cons
- Requires USB-C charger
- Second 4K display is 30Hz rather than 60Hz
- Third display is HD not 4K
- Connection: USB-C
- Software: DisplayLink
- Max screens: 3
The EZQuest Ultimate Plus USB-C Multimedia Hub has two HDMI ports and a VGA port, and supports one 4K at 60Hz and one 4K at 30Hz via HDMI and 1080p HD via VGA. If you want three 4K displays, look instead at the Ugreen Triple Display Dock.
It also features 5Gbps USB-A ports, Gigabit Ethernet and card readers.
Like the Ugreen dock, it requires a USB-C charger for power and can pass through up to 85W to the connected MacBook, but connects via slower 5Gbps USB-C.
Baseus 17-in-1 Docking Station – three 4K displays at 30Hz
Pros
- Supports three external displays at 4K 30Hz
- 15 (actual) ports
- 85W PD
Cons
- Requires USB-C charger for laptop
- 30Hz 4K not 60Hz
- Only mirrors laptop display
- Connection: USB-C
- Software: DisplayLink
- Max screens: 3
The Baseus 17-in-1 Docking Station has three HDMI ports, each of which can connect to an external 4K display at 30Hz. If you require three 4K external displays at 60Hz, the Ugreen Triple Display Dock will fulfill your needs better. If 30Hz is fine, the Baseus will save you money. 60Hz is better for gamers as it offers smoother video.
One big limitation for Macs, though, is that the external displays can only mirror and not extend the Mac’s screen.
Its claim to have 17 ports is exaggerated slightly as one is for the external power supply that powers just the dock at 12W. and another to add power the dock via a USB-C charger and then onto the laptop. But it has 15 other ports including the upstream 5Gbps USB-C connection to the MacBook, plus Gigabit Ethernet, card readers and 5Gbps USB-A and USB-C ports.
Pros
- Supports three external displays at 4K 60Hz
- 15 ports, inc. 10Gbps USB-C and USB-A
- 85W passthrough charging
Cons
- No card reader
- DisplayPort didn’t work on our test Mac
- Connection: USB-C
- Software: DisplayLink

This triple-monitor DisplayLink-based docking station is positively bristling with ports: 15 in total.
Most interesting to us here are the six video ports: 3x DisplayPort 1.4 and 3x HDMI 2.0. This doesn’t mean you can connect six displays but it does should give you flexible options for the type of connection that fit your displays. However, in testing we had no success linking via DisplayPort, which makes the extra options rather worthless. As such, we prefer the other docks and hubs reviewed above.
You need to download the DisplayLink drivers for your M1/M2/M3 Mac. StarTech.com has a link and a video, or just follow our guide above.
As well as the half-dozen video ports are six USB ports: 2x USB-C (one at 10Gbps and one 5Gbps), plus 4x USB-A (one 10Gbps and three 5Gbps). The 5Gbps USB-C port can charge a connected device at 18W, enough to fast-charge an iPhone. One of the 5Gbps USB-A ports can charge at 7.5W.
Rounding off the many ports are Gigabit Ethernet and a 3.5mm Audio In-Out.
There’s no card reader to add portable storage but you could connect an adapter to one of the USB ports.
Workaround caveats
Whenever there is a new OS update DisplayLink and InstantView drivers may need to be updated each time.
Plugable doesn’t recommend the workaround for gaming, video editing, digital audio workstations (DAWs), and protected content (HDCP) playback. For these workloads, users will want the full throughput of a “bare-metal” native GPU connection—such as provided by the DisplayPort or HDMI port on the dock using Alt Mode.
CalDigit actively recommends against using DisplayLink, as it finds it unreliable and there would be no synergy between the driver and the dock. Because it requires a third-party driver, users are at the mercy of Apple and the third-party developer to support later versions, the company told Macworld.
However, this combination of display technologies does allow M1 and M2 MacBooks to run more than one external monitor, and the M1 and M2 Mac mini to run more than two. And more manufacturers are coming out with docks and hubs that support it.
The only risk is that it could stop working at any time, although it wouldn’t harm your system if it did, and you could simply uninstall DisplayLink.
DisplayLink and InstantView are workarounds with a potentially limited timespan but the likelihood is that compatibility would be restored at some stage if the worst happened and you would get back your multi-monitor setup.

What you need to know about DisplayLink and InstantView
FAQ
Does DisplayLink and InstantView block Netflix or other streaming content?
DisplayLink and InstantView are great at adding multiple monitors to M1, M2 and M3 Macs, but there is a catch.
Some protected content in Netflix, AppleTV, Amazon Prime, Disney+ or YouTube TV and other streaming applications may not play. The video remains black while audio keeps playing.
This is all down to how the macOS interfaces the DisplayLink driver used to access graphics content. As soon as one DisplayLink-enabled screen is connected, protected content becomes unavailable on all screens.
This is down to the streaming platforms using High-bandwidth Digital Content Protection (HDCP), which is Intel-developed digital copy protection that prevents copying of digital audio and video content as it travels across connections.
Because macOS requires DisplayLink and InstantView to enable Screen Recording, HDCP moves in because it thinks you are actually trying to record the content rather than just display it on screen.
How to enable streaming content when using DisplayLink or InstantView
To get round HDCP stopping your DisplayLink or InstantView setup showing Netflix, Amazon Prime and other streaming services, you may need to disconnect all the DisplayLink or InstantView screens, or switch to a browser other than Safari or Chrome (for example Opera or Firefox).
You can disable hardware acceleration in your browser to access the protected content.
On Google Chrome, go to Google Chrome settings, and click on “Advanced” and then select “System”. Here you can disable “Use hardware acceleration when available”.
Select “Relaunch” to activate the new setting.
If that doesn’t solve the black issue, disconnect the docking station, and try using the laptop’s build-in display or the direct video ports of the laptop.
Uninstalling the software is the ultimate solution.
