M1 Macs cannot support dual Extended displays through their Thunderbolt 3 ports
- jbub 6y agoI think this was clearly stated, nothing shocking about that right ?
- gbil 6y agoright, I think the title should change to indicate that the link is dated from November, just after the M1 Macs announcement and nothing new
- izacus 6y agoWhile its stated in the tech specs, it might still be surprising for current MacBook users. The M1 was loudly marketed as strictly superior to previous CPU/GPUs so regression in I/O and screen support might be easily missed.
- ogre_codes 6y agoThe MacBook Air, the Mac mini, and the baby Pro are the M1 options right now, so people are trying to bodge them into being something they aren't. I've heard a lot of stories of people who bought them not expecting to replace a 15" MBP or even iMac with a MacBook Air. Then once the bits hit their shiny new CPU they went whole hog.
- contingencies 6y agoMight work with one wired and one wireless. Otherwise, maybe with an external graphics card if supported, failing that a VNC or other network display protocol server streaming to an external rendering unit across ethernet or wifi. But honestly, I think we reached peak multiscreen ~2010 and it's sort of falling out of favour these days except in a minority of fixed workstation environments. In which case, I'd be waiting for the 16" Pro later this year.
- EarthLaunch 6y agoNailed it about peak multiscreen. I was on three screens when everyone was on one, then on the highest consumer DPI monitor in 2009 before Retina or Windows OS support, and now I'm on a single-monitor display with a laptop. In 10 more years that will be the format: Laptop below, 8k 40" atop.
- kgc 6y agoOr just a cellphone that plugs into a monitor.
- hombre_fatal 6y agoI would think that would already exist if it was actually compelling. But having to plug your computing device into a monitor and keyboard to do any work is just a downgrade from a laptop that always has a monitor and keyboard. It's a bizarre portability trade-off that's even less exciting as laptops become thinner, lighter, and more powerful.
- nkerkin 6y agoAre you saying it doesn't exist, or just that it's not compelling? I'm typing this comment on a phone connected to a standard monitor, running a desktop-like experience [0] and it's surprisingly usable! Hardware - Samsung S8 (2017), generic USB-C to HDMI adapter, bluetooth keyboard and mouse. [0]https://www.samsung.com/au/apps/samsung-dex/ https://www.samsung.com/au/apps/samsung-dex/
- robbiet480 6y agoThis and the smaller screen sizes are the reasons we won’t be rolling out any M1 machines at Flatfile. Excited for them otherwise though!
- AceJohnny2 6y agoFWIW, I am currently using a CalDigit TS3+ with a (Intel) MBP, with dual displays (one over DP, one over USB-C (DP)). They work as separate displays, not mirrored. I also tested an HP G2 Dock [1], because its dual-DP ports gave me more options, only to find that macOS can only use those two ports as Mirrored to each other. Apparently [2], this is because the HP G2 implements its two DP ports as DP1.4 MST (Multi-Stream) on a single link, and in that mode macOS will only support a Mirrored configuration. It cannot (as of Big Sur 11.1) use them as separate displays. I'm told you can also use the HP G2 with separate displays by plugging one monitor into one of its USB-C outputs, kind of like how I'm using the CalDigit TS3. I tried the one labeled USB-C (DP), and that stayed mirrored, but apparently I should've tried the Thunderbolt downstream port instead. I returned the dock before I knew or could try this. All this to say, I'm disappointed by the mess of an ecosystem that Apple has built around Thunderbolt 3. But I can't say I'm surprised.

- AceJohnny2 6y agoThe M1-based macs support USB4, which is conceptually an upgrade over TB3 (supporting multiplexed streams of PCIe, DP, and USB). However Apple conspicuously does not prominently advertise that support, which I'm guessing is due to a lack of ecosystem.
- dijit 6y agoUSB4 is prominently displayed on the Marketing and tech-spec pages for the M1 Macs: https://www.apple.com/macbook-pro-13/specs/ https://www.apple.com/macbook-pro-13/specs/ https://www.apple.com/macbook-pro-13/ https://www.apple.com/macbook-pro-13/
- strobe 6y agojust in case, OWC Thunderbolt 3 to Dual DP [1] adapter work fine with two 4k@60Hz separate displays (with MBP15 2019). And seems similar Thunderbolt3 -> Dual DP adapters also should works well. But I agree that is a big mess with that stuff, I brought lot of usb-c->hdmi adapters before found solution with works fine with 2 displays (some of those adapters only supports 30Hz, some can slow-down MBP performance dramatically with 2 displays).

- Oras 6y agoI have used DisplayLink [0] to connect M1 to two monitors via DP and worked well. It not fully plug and play, I had to install displaylink software. However I noticed that if I connect the other port to charger it would (sometimes) add some latency to running apps (for example safari might not respond immediately or vscode will take few seconds to load).

- zeusk 6y agoDisplayLink (as it's name might suggest) has nothing to do with DisplayPort. DisplayLink runs a compressed video stream over host USB to an external box (which decodes that compressed stream and pipes it to the dual DP ports on the box).
- petepete 6y agoI read bad things about getting Thunderbolt working properly with Linux so bought a DisplayLink port extender (Lenovo) and it was an awful experience. Janky, didn't support the later kernel versions, didn't have a RPM or Fedora repo, crashed a few times a week. Awful. Since then I've also bought a TB one and it works flawlessly. The DL one sits on my desk at work as a glorified charger now.
- uncledave 6y agoI eagerly await the day all these display standards problems go away. I can throw away the large box of miscellaneous USB-C, DisplayPort, HDMI and adapter dongles I have and might grow some hair back. Just yesterday I was arguing with something that had a USB-C to HDMI which didn’t support 60Hz on one monitor but was fine on another. Grr.
- pentae 6y agoAnd you can bet by the time that day comes we'll have a new USB-D / USB 6 connector to get new adapters for and Apple will bravely drop USB-C from their laptops in favor of this new standard.
- swyx 6y agoI often dream of a centralized service where everyone can send in all their backup cables and then pay a subscription to get any of someone else's cables in exchange if they need it. things that aren't used for >5 years get responsibly recycled. too scared about the warehousing and the complexity to do it myself but its probably something I'd pay $5 a month for just for the peace of mind and freed up space.
- bni 6y agoWhat makes you think it will go away? If anything I think it will get worse as there will be even more USB connector types introduced, and screens with even higher resolutions and refresh rates that todays cables don't have the bandwidth to support.
- rsynnott 6y ago> I eagerly await the day all these display standards problems go away. Based on the history of display standards, you will be waiting a while. Displayport was meant to be the magical works-for-everything standard... then the various versions of Displayport started showing up.
- Jonnax 6y agoAre you talking about versions of Displayport or something else? Because people want to use 4k@120hz+ or 5k+ displays. Which require more bandwidth
- sgt 6y agoThis seems laptop specific, i.e. having the MacBook + 2x external extended displays via Thunderbolt. I think surely the Mac Mini M1 works with 2x monitors though (extended)? Has anyone tested this?
- g_p 6y agoThe Mac mini M1 can drive two independent screens - one over HDMI, one over USB C. The limitation seems to be number of screen outputs, and a laptop has one already built in, hence only 1 external.
- sgt 6y agoThat is what I'm planning to do. Mac Mini with two 4K screens running at 60Hz. Was just making sure that it would work.
- sirn 6y agoI've been running this setup. Mac mini M1 connecting to LG 4K monitor over HDMI at 60 Hz, with DisplayPort to a 4K Wacom Cintiq also at 60 Hz. It works flawlessly.
- sgt 6y agoOut of interest's sake, what kind of resolution are you running? I found 3008x1692 to be perfect for my 4K screen, but it actually doesn't show up in Display preferences unless you option-click the "Scaled" radio button.
- sirn 6y agoI'm using the standard scaled 1920x1080 resolution on both of my screens. I don't see the 3008x1692 option on my 27-inch LG 4K, but I do see the option on 16-inch Wacom Cintiq. It's a little bit too small on my 16-inch, though.

- qwerty456127 6y agoWhy do M1 Macs (which are supposed to be new) even have Thunderbolt 3 ports? I would expect Thunderbolt 4 these days.
- astrange 6y agoThey’re the same port. TB4 is TB3 + USB4 + two display support (and maybe some other things?). The M1 isn’t compliant because of the display limit, but it does have USB4.
- qwerty456127 6y agoI see. Thank you. I thought Thunderbolt 3 is MiniDisplayPort. By the way, can I convert the MiniDisplayPort Thunderbolt port on an old MacBook Air into a USB 3.2 gen 2 host port to connect an M.2 NVMe enclosre?
- izacus 6y agoM1 seems to be pretty heavily I/O limited - the amount of supported Thunderbolt ports is way down (2 on every M1 device and no more), the screen support is down as well. Hopefully they fix it in the next iteration.
- sirn 6y agoIt might be worth noting that M1 Macs actually has two Thunderbolt controllers for 2 ports (dedicated controller for each port), whereas previous Macs shared two Thunderbolt controllers for 4 ports. The 2 ports limitation feels to me like a design decision rather than a hardware limitation (to differentiate with an upcoming higher-end model?)
- chrischen 6y agoThe distinction is moot since hubs don’t exist, so I’m still facing the problem of lack of physical inputs. At best on the market there are hubs that give 1 extra type c input for power.
- sirn 6y agoThere's a recently announced OWC Thunderbolt Hub[1]. I would still prefer to have 4 ports built-in even with two controllers rather than having to deal with hubs, though. [1]: https://eshop.macsales.com/shop/owc-thunderbolt-hub https://eshop.macsales.com/shop/owc-thunderbolt-hub
- chrischen 6y agoI did see this and it’s a bit sad that it’s been like 4 years since type c has come and hubs still aren’t generally available (even if just for USB and not thunderbolt). I mean I didn’t fully adopt USB type C just to convert the ports back to type A.
- sirn 6y agoThis is mostly because Thunderbolt hub support was optional in Thunderbolt 3 spec, but mandatory in USB 4. Apple just added support for it in Big Sur.
- tandav 6y agoAlso usbc on M1 is slower than on 16 inch macbook pro https://www.google.com/search?q=m1+usb+speed&oq=m1+usb+speed https://www.google.com/search?q=m1+usb+speed&oq=m1+usb+speed
- vetinari 6y agoWifi is also slower, M1 Macs have only 2x2 MIMO chip (Broadcom BCM4378). In AC mode (5 GHz, HT80), it maxes with 866 Mbps link speed. Intel Macs are faster in this regard.
- dx034 6y agoDo theoretical speed limits matter though? Real speeds will be much lower anyway. And if you need consistent high speeds you're likely to use a cabled connection anyway.
- vetinari 6y agoI've found out, because wifi was subjectively slower. 5 GHz is nice, because the range is lower, your neighbors are not causing much noise anymore, so the real speeds did approach the theoretical limits (for me; in my environment; using Ubiquity APs, mostly nanoHDs). Apple used to be one of the vendors, that bothered to put better wifi in their products than competitors; now they fell back to mediocre 2x2 that all the PC vendors use.
- lloeki 6y agoMore MIMO antennas means better resilience against interference, the higher theoretical value is a non-quantitative proxy for that.
- rsynnott 6y agoThe two port 13" always had 2x2, didn't it? That said, I wouldn't necessarily expect the 16" MBP to have 3x3 either. Last time I checked, laptop oriented wifi6 3x3 chipsets didn't exist (though something may have shown up in the last few months)
- spiderfarmer 6y agoI recently switched to a single 6k monitor after using dual monitors for 10+ years. A single high res monitor is so much better ergonomically.
- bosswipe 6y agoEspecially on macOS with its crappy window manager.

- JansjoFromIkea 6y agoLove it but important to note "Spectacle is no longer being actively maintained" and it has been like that for over a year
- KORraN 6y agoYup, hence mentioned above Rectangle: https://github.com/rxhanson/Rectangle https://github.com/rxhanson/Rectangle

- Hates_ 6y agoRectangle is an alternative that's actively supported: https://github.com/rxhanson/Rectangle https://github.com/rxhanson/Rectangle
- real-dino 6y agoMeanwhile Intel Macs can't support external displays without using the discrete GPU and thermal throttling under moderate workloads. They are completely unsuited for multi-monitor workloads without an eGPU. More specifically, the draw 30W of additional power that has to go somewhere. You can turn down the refresh rate, to say 10Hz or something, but it still has to use the discrete GPU. The cooling solution simply isn't handled to deal with it, as they have crammed as much processing power they can into the ultra-light chassis. Meanwhile you can play World of Warcraft whilst drawing just 25W of power TOTAL on the M1 (estimate, I don't play WoW anymore). This is while the Intel Mac is drawing 70-100 Watts from the socket for just rendering a window to the secondary display. It's got to the stage that I prefer to use my 13 inch M1 over a top of the line 16 inch provided by work. When M1 finally supports docker, I might even consider not using the 16 inch at all. It crashes due to thermals about twice a week due to the constant high temperature and eats through batteries! If anyone has a solution to this, I'm all ears, but it feels like every nay-sayer of the M1 is dismissing just how many compromises Intel based laptops (not just Macs) have. I had just as many issues with the Dell XPS, where even basic video games would become unplayable after 15 minutes due to CPU throttling down to 0.8 Ghz. The M1 has been the first laptop I have been truly happy with as a desktop user.
- chrischen 6y agoI just ditched my maxed out 16” for a “low end” M1 13” because my actual benchmarks of my day to day node compiling is seconds faster on the M1. For docker I plan on using a pi 4 or another PC to just run stuff over the network.
- tachion 6y agoWhat's the point of using Pi 4 when it is also ARM cpu? You can use the Docker beta on your M1 mac and it's going to be a better experience.
- chrischen 6y ago1) problem isn’t arm. It’s m1 support. The developer preview still has some kinks. 2) free up memory on my mac. I’m working at home so using a networked computer isn’t a big deal.
- deltron3030 6y agoI think they'll go wireless and offer a fancy wireless adapter, using the same tech they use for Sidecar – with it you can hook up iPads as external displays.

- ThePhysicist 6y agoEven the new Thinkpads can't support two external 4k monitors through the USB-C docking station. You can plug in one monitor via HDMI and another one via the docking station though, which is not optimal but still ok. Anyway, as others have pointed out, using a single large external monitor is usually better than using several, and most of my colleagues already switched to 42 inch curved widescreen monitors recently. I'm still using two 3k/4k external monitors as they're still in good working condition, next time I upgrade I'll get a single large monitor as well though.
- martin8412 6y agoThat's due to USB 3 not having enough bandwidth for 2x 4k monitors at 60Hz. Get a Thunderbolt 3 Dock instead if your laptop supports it, and you can have 2x 4k monitors at 60Hz.
- jarpineh 6y agoIncidentally, I was just looking at Mac M1 mini display support. I have LG UltraFine 4K USB-C and 5K display port (not the LG one) monitors. M1 can support 5K only through USB-C. This leaves me with HDMI to USB-C so that LG too can be connected. It seems LG speaks display port under USB-C, so there might be a way. Adapters would be some 60-100$ just to test this, though. Other than that I’m all set for M1. My 2018 MacBook Pro needs power 2-3 times a day no matter how much I try to weed apps. Something remotely strenuous happens fans take off.
- zenexer 6y agoIt's worth noting that there are workarounds, although none are particularly great: 1. The Mac mini form factor officially supports two external displays. One must be DP/TB3, the other must be HDMI. However, I would argue that the Mac mini is the least enticing form factor in the new line unless you have very specific requirements, and the need for two different protocols is both annoying and confusing. 2. Sidecar works just fine. This is my current solution of choice. 3. You can configure a Raspberry Pi to act as an AirPlay display. The software I attempted had a hardcoded resolution, and any attempt to change it failed.[0] You can see from that issue debugging is still a work in progress, but it's fairly tedious, and I haven't made much progress since my last reply--all of my attempts have failed to produce meaningful info. However, if you have a screen with a very common 16:9 resolution officially supported by lots of Apple devices, this will likely work quite well. 4. You can use an Apple TV as an AirPlay display target, provided your monitor is one of the supported 16:9 resolutions. 1920x1080 is a safe choice. 5. You can get an AirPlay-capable display. I haven't really looked into this, as it seems like a fairly limiting criterion. I suspect my options would be limited to projectors and overpriced TVs. I could be wrong--again, I haven't checked. 6. Some people have reported being able to get DisplayLink working.[1] I plan to try this, but I haven't gotten around to figuring out which of my adapters support DisplayLink. I'm hoping I'll be able to get this to work with the adapter plugged into my CalDigit TS3+ dock so I only need one cable. Side note: despite the limitation, I got a CalDigit TS3+ just to dock my M1 MBA. My Intel-based MBP had four TB3 ports, which meant I could connect it to my dual-monitor KVM with three cables (2x DisplayPort + 1x USB) and still have one for power. However, even with only one DisplayPort cable, there still aren't enough ports on either the M1 MBP or M1 MBA. It works great, aside from the fact that I'm wasting a monitor.

- sonotmyname 6y agoRe #5, pretty much every 2020 TVs from Sony, LG, Vizio, Samsung, et all support Airplay 2. This was largely a result of Apple's push with AppleTV+.
- statico 6y agoI wrote a comment on DisplayLink below: https://news.ycombinator.com/item?id=25675013 https://news.ycombinator.com/item?id=25675013 It works, and it's the only option, but you won't like it.
- snarfy 6y agoI'm more impressed with tsmc's 5nm process than the M1. It will be interesting when we have more processors out manufactured on the same process.
- epmaybe 6y agoCan anyone comment on if the m1 MacBook Air can handle 4K external display well enough for daily use? I know it handles my ultra wide 1440p display, but I wanted to confirm before I purchased a 4K display.
- kube-system 6y agoI've been using a single 4K display with mine -- works great.
- ed25519FUUU 6y agoMy m1 MacBook Air drives my 4K monitor better than my top of the line 2019 MBP. With my MBP the fans turn on when it does anything other than look at the 4K desktop.
- itsoktocry 6y ago>With my MBP the fans turn on when it does anything other than look at the 4K desktop. Some of this conversation confuses me. Since the M1 MacBooks came out, all of a sudden people are talking like every MBP version prior is junk. Top-of-the-line MBP that can't run dual monitors? Where were these conversations about poor MBP performance 6 months ago? FWIW, the last MBP I had was a 2015 i5, and I used a single 4k monitor and no had zero issues in regular usage.
- epmaybe 6y agoI tend to agree, had a 2017 MBP prior, but the laptop certainly got hot and things had to throttle a little. Had I not tried an M1, I doubt I would have noticed.
- ogre_codes 6y ago> Some of this conversation confuses me. Since the M1 MacBooks came out, all of a sudden people are talking like every MBP version prior is junk. Top-of-the-line MBP that can't run dual monitors? Where were these conversations about poor MBP performance 6 months ago? The 15/16" MBP is certainly capable of supporting 4K displays without issue (posting from one now). Most likely some people have something screwed up in their setup and didn't realize it until they moved to another system. With the new MacBook Air, they won't even know their setup is screwed up because there won't be any fan noise. It'll just slowly degrade over time.
- rbosinger 6y agoThis has been a big one for me in regards to pulling the trigger on an M1 (and I need something new for work very soon). I found a whole bunch of YouTube videos of people using DisplayLink adapters such as various docks from Targus or smaller single adapters from StarTech (brands likely don't matter but this happens to what people are testing in these videos). They all show good results. Comments all say "DisplayLink is faking it and it's gross" but the people making these videos say "Sure, but it's not gross. It's working almost perfectly." Anyone here have any experience or thoughts on this? I'm not gaming or needing to do high level graphics or video editing on a 2nd or 3rd display. Just basic dev stuff and window management.
- Trun222 6y agoI have the new MacBook Air and am able to run two 1080p monitors just fine. I use the same adapter for gaming with my HP omen as well. It looks great. (StarTech)
- statico 6y agoI bought the StarTech dual 4K DisplayLink adapater after watching one of those videos. I use it to power a second 4K monitor with my M1 MacBook Air running lid-closed. I have a 1080p gaming monitor as my primary connected to a Elgato dock via DisplayPort. DisplayLink is definitely suboptimial, but it's the only option. There is noticable input lag (my guess is around 100ms) that makes mouse and keyboard input feel sluggish. Showing a moving image on the screen pegs the DisplayLink Manager process to 100% of one core while it's playing. DisplayLink does not currently support rotation on Big Sur, though it probably will in the future. However, the image itself is pixel-perfect, so it's fine for secondary apps like chat or monitoring.
- rbosinger 6y agoThanks for the answer! > There is noticeable input lag (my guess is around 100ms) that makes mouse and keyboard input feel sluggish. That's interesting to hear. In some of these videos (and additional Reddit/YouTube comments on them) it seemed like a lot of people would say "yeah but it will have lag" and the person making the video would claim that it doesn't seem to while dragging windows all over the place in their videos. The rotation seems to be a problem across the board though. These things are difficult to dissect. It could be that there is lag for these other guys, but they aren't the type to notice. Or maybe they didn't get lag because of some detail in their set-up that differed from yours. Oh well. I don't even have two monitors right now and probably don't really have enough room for a second one. I had hoped to get one this year though. Maybe I'll get the M1 and just keep working with the one monitor. If I decide it's time for an upgrade maybe I can go the route discussed elsewhere in this thread and get an ultrawide, or a single 40+ inch 4k. EDIT: Video example of what I'm talking about: No lag with a displaylink second display on the 2020 M1 MacBook Pro! https://www.youtube.com/watch?v=k1J3lSZfrko https://www.youtube.com/watch?v=k1J3lSZfrko He's not typing anything though. But for this guy it generally _looks_ like it's close to behaving like a normal second monitor. But then here's this thread complaining that a particular dock, with 4k displays, is super laggy: https://support.displaylink.com/forums/287786-displaylink-feature-suggestions/suggestions/41175478-fix-drivers-about-screen-lag-when-using-external-4 https://support.displaylink.com/forums/287786-displaylink-fe...
- runjake 6y agoSince I get asked this about my M1 a lot, you can however: - Use a quality DisplayLink adapter that will give you an additional display over the USB bus. It's unsuitable for gaming or video, but it's perfectly suitable for coding, web browsing, and office work. - Use the internal display while using a single external monitor. People seem to not understand this often.
