Apple’s vary of MacBooks that use the corporate’s personal Silicon M1 or M2 processors can’t natively join multiple exterior monitor, which is an enormous limitation on the earlier Intel-based era of Mac laptops that might run two shows when related to a USB-C or Thunderbolt 3 docking station or hub.
The M1 Pro and M1 Max do assist a number of exterior shows. We hoped the M2 would lose the M1 limitation, nevertheless it survives on the plain M2; when obtainable, count on the M2 Pro and M2 Max to assist extra shows, similar to their M1 siblings.
However, there are methods round this M1/M2 limitation, permitting you to run two exterior shows off an M1 MacEbook, which we are going to define right here. There’s a software program driver plus {hardware} adapter workaround and a hub or adapter workaround.
With the software program workaround, there are some dangers concerned as you’ll be required to put in third-party drivers, and these may later be unsupported by future updates of the macOS. And you’ll doubtless have to purchase at the very least one adapter, the place beforehand a dock plus a show cable per exterior display screen would have sufficed.
The {hardware} resolution entails a dual-HDMI adapter that requires just a little tinkering in System Preferences at setup.
If you waited for Apple’s newest 14in or 16in M1 Pro M1 Max MacEbook Pro fashions, you’re in luck as these laptops do assist a number of exterior shows. Laptops with the M1 Pro can connect with as much as two exterior shows with as much as 6K decision at 60Hz, whereas MacBooks with the M1 Max can join to 3 exterior shows with as much as 6K decision and one exterior show with as much as 4K decision at 60Hz.
M1/M2 house owners, begin saving for a brand new MacEbook Pro or learn on.
External shows: M1 and M2 Macs’ huge drawback
Apple’s Mac mini, MacEbook Air, and MacEbook Pro 13in had been the primary Macs to characteristic the Apple-designed M1 CPU. They obtained rave opinions for his or her velocity enhancements over Intel-based laptops, together with right here on Macworld.
See our comparability of the 13in MacEbook Pro (M1) vs MacEbook Pro (Intel) and MacEbook Air (M1 Silicon) vs MacEbook Air (Intel). We have additionally appeared on the variations between the Mac mini (M1) and Mac mini (Intel).
But in case your MacEbook setup contains operating multiple exterior show, you might have a serious drawback. Apple’s M1 or M2 chips merely gained’t think about it—at the very least natively.
Apple states within the M1 and M2 MacEbook Air and MacEbook Pro tech specs that they assist solely “one external display with up to 6K resolution at 60Hz”.
Apple
While the M1 and M2 MacBooks natively assist only one monitor, the M1 Mac Mini does natively assist as much as two exterior displays—one by way of the HDMI port and a second by way of USB-C. But the M1 fashions of the MacEbook Air and MacEbook Pro assist just one exterior show.
Apple has apparently promised to repair the issue in a future macOS replace, however the arrival of the later M1 Pro and M1 Max—and extra just lately the M2—recommend that M1 house owners could possibly be ready a very long time. We have this information to Monitors for M1 Macs and what you could know earlier than shopping for.
Workaround #1: set up DisplayHyperlink software program drivers
Docking station producer Plugable suggests utilizing a mixture of show applied sciences to get across the M1/M2 MacBooks’ single-monitor limitation. This ought to work with most third-party docks, though many producers don’t advocate it.
Plugable’s multi-display docks use a mixture of native USB-C Alternate Mode (native “Alt Mode” video output) and DisplayHyperlink expertise. This mixture serves as a workaround to the M1/M2 platform supporting solely a single exterior show by way of USB-C.
Note that DisplayHyperlink requires a third-party driver to be put in on the Mac. There are completely different variations of the DisplayHyperlink driver, and a few carry their very own compromises to the celebration.
And this resolution nonetheless requires an additional {hardware} adapter.
The DisplayHyperlink macOS app or DisplayHyperlink Manager app are methods of enabling DisplayHyperlink expertise on macOS. The app is out there as a standalone installer moderately than by way of the mac App Store.
1. First, obtain the most recent Mac DisplayHyperlink driver.
DisplayHyperlink Manager Graphics Connectivity App v. 1.1.0 is suitable with macOS Catalina 10.15, macOS 11 Big Sur and macOS 12 Monterey. It might be managed by way of the DisplayHyperlink icon within the Apple Menu bar.
The macOS requires the consumer to allow “Screen Recording” to ensure that DisplayHyperlink gadgets to work correctly. This might be present in System Preferences underneath Privacy in Security & Privacy; navigate to Screen Recording within the checklist on the left, then tick the Screen Recording permission for DisplayHyperlink Manager after unlocking the padlock utilizing your admin password. You might have to stop and restart DisplayHyperlink Manager afterwards.
More in-depth particulars on DisplayHyperlink Manager underneath macOS Big Sur, Catalina and Monterey, on this DisplayHyperlink assist web page.
Installation is easy, however word that this model doesn’t assist laptops’ closed-display/Clamshell mode.
Other limitations embody incompatibility with show rotation. Rotation on Apple M1/M2 requires DisplayHyperlink Manager 1.6+ with macOS 12+.
There’s an choice in DisplayHyperlink supervisor to “launch at startup”, or you possibly can drag the DisplayHyperlink Manager to your Login Items in Users & Groups.
Note that M1/M2 MacBooks can run in Clamshell Mode (that means with the lid closed) with Displaylink connected displays, however Intel-based MacBooks can’t and the shows will shut off when the laptop computer lid is closed if utilizing DisplayHyperlink. This gained’t matter that a lot as Intel MacBooks can run two shows with out DisplayHyperlink, though they are going to want DisplayHyperlink so as to add three or extra displays.
2. Then join the MacEbook to a dock, such because the Plugable UD-ULTC4K Triple Display 4K Docking Station or the Caldigit TS3 Plus dock. Learn extra about the most effective Thunderbolt 3 docking stations for extra particulars, or you possibly can join by way of an easier USB-C hub.
3. For the primary display screen you possibly can join by way of the dock’s DisplayPort or HDMI Port, and this can be dealt with natively by the M1/M2 MacEbook.
You may additionally join the primary exterior show by way of a Thunderbolt 3 or USB-C to HDMI or DisplayPort adapter.
The HDMI or DisplayPort output makes use of Alternate Mode (Alt Mode), and as it’s principally a pipeline on to the system’s native GPU, it would behave similar to should you attached a USB-C to HDMI dongle to your laptop computer. This requires no consumer driver set up.
4. Additional shows can’t be dealt with natively by the M1 MacEbook.
You want to connect the second or third show by way of a number of of your dock or hub’s USB-A ports, utilizing an adapter resembling StarTech.com USB 3.0 to HDMI / DVI Adapter. This prices £80 or US$80, so must be factored in when pricing an M1/M2 MacEbook buy should you require a number of displays.
Another choice is Plugable’s USB Dual 4K Display Adapter.
This adapter turns an obtainable USB-A 3.0 port into one DVI-I or VGA port (DVI to VGA adapter included) and one HDMI output. Each show can concurrently assist the utmost decision of 2048×1152 at 60Hz.
Make certain to make use of an energetic HDMI DisplayHyperlink adapter that may assist 4K at 60Hz, as some are restricted to 4K at 30Hz.
DisplayHyperlink makes use of an put in driver and the system CPU and GPU to transform graphics knowledge on the system into USB knowledge packets. That USB knowledge is then despatched over the USB cable as knowledge packets, and transformed again to video info and output to the displays by way of the DisplayHyperlink chip within the docking station.
Workaround #2: Use a particular Dual HDMI adapter
Accessory maker Hyper sells two {hardware} options that mean you can add multiple show to an M1 or M2 Mac.
The Hyperdrive Dual 4K HDMI Adapter for M1 MacEbook and Hyperdrive Dual 4K HDMI 10-in-1 USB-C Hub can lengthen to 2 HDMI shows: one at 4K 60Hz by way of HDMI and DP Alt-mode, and one at 4K 30Hz by way of HDMI and Silicon Motion’s InstantView expertise.
Hyper says that these work “without having to download cumbersome drivers” however there may be some software program set up concerned, and you could permit InstantView entry to your Privacy settings in System Preferences. You join the hub or adapter to your M1 MacEbook and discover the HyperDisplay app that seems in a Finder folder sidebar. Double-click the macOS InstantView icon and observe the System Preferences directions. Once this has been accomplished your MacEbook will mechanically recognise the adapter from then on.
The Dual 4K HDMI 3-in-1 USB-C Adapter ($129.99) options two HDMI ports and connects to your M1 Mac by way of its built-in USB-C cable. An extra USB-C PD port means that you can cost the related laptop computer at as much as 100W—useful because the adapter itself makes use of up certainly one of your M1 or M2 laptop computer’s two Thunderbolt ports.
A extra absolutely fledged resolution is the Dual 4K HDMI 10-in-1 USB-C Hub ($199.99), which boasts 10 ports, together with the 2 HDMI ports and 100W PC port seen on the cheaper adapter, plus Gigabit Ethernet, 3.5mm Audio Combo Jack, SD and MicroSD UHS-I card readers, and two USB-A (5Gbps) ports. It too connects to the laptop computer by way of an built-in USB-C cable. Of the 2, this multi-port hub is best worth as you should use it as a dock when it’s related to an honest USB-C PD wall charger.
Buy direct from Hyper. Shipping to the UK is at the moment a steep $66, so issue that in if you’re not based mostly within the US.
DisplayHyperlink route efficient however unsupported
Note that neither Plugable nor Caldigit formally helps such a DisplayHyperlink setup for Macs. The resolution works, however they warn that this might turn out to be unstuck in future variations of the macOS.
Whenever there’s a new OS replace the drivers might must be up to date every time.
Plugable doesn’t advocate the workaround for gaming, video modifying, digital audio workstations (DAWs), and protected-content (HDCP) playback. For these workloads, customers will need the total throughput of a “bare-metal” native GPU connection—resembling supplied by the DisplayPort or HDMI port on the dock utilizing Alt Mode.
Caldigit actively recommends in opposition to utilizing DisplayHyperlink, because it finds it unreliable and there can be no synergy between the motive force and the dock. Because it requires a third-party driver, customers are on the mercy of Apple and the third-party developer to assist later variations.
However, this mix of show applied sciences does permit M1 and M2 MacBooks to run multiple exterior monitor, and the M1 Mac mini to run greater than two.
The solely threat is that it may cease working at any time, though it wouldn’t hurt your system if it did, and you might merely uninstall DisplayHyperlink.
So it’s a workaround with a probably restricted timespan however the chances are compatibility can be restored at some stage if the worst occurred and you’ll get again your multi-monitor setup.
The Hyperdrive twin 4K HDMI {hardware} resolution seems to be the costlier however secure workaround of the 2.
