Silly question: But why does B&H show a quicker availability for the TS4 than Caldigit? Asking for a friend.

@@reginaldwalton B&H is receiving the rest of the first shipment, so they tentatively have some pre-orders available.

@@CalDigitHQ not that I saw. i wasnt able to preorder just says available soon.

@@joeldiramon8538 I was able to order it from B&H two days ago. They may have limited the number of pre-orders.

@@joeldiramon8538 The pre-order period may be closed already or they've gone through all the units.

Thanks for the comment! Glad to hear it!

Just caught your question in the other video. Sorry I missed you until now, but happy to hear you found an answer over here!

Glad to hear it! If there's anything we can ever help with, please don't hesitate to reach out!

You can always daisy-chain the docks together too, if you're feeling a little wild!

@@CalDigitHQ That is a crazy idea.... hmm... will try it.

You can get dual 4k144hz monitors as long as the monitors and computer support Display Stream Compression (DSC), so 144hz at a lower resolution is also possible.

@@CalDigitHQ I'm using M1 Max Macbook Pro. As I mentioned, I don't want to use any compression like DSC on my primary external monitor, the Dell g3223q, because I don't want any compression on the image. Can I use a second 1080p monitor at 144Hz?

@ I don't think DisplayPort 1.4 is capable of reaching 4k144hz without using DSC. The cap is 4k120hz at 8bpc I believe. 1080p144hz would work just fine without DSC. I believe 1440p144hz is also achievable.

More units are coming! You can find the most up-to-date info right here: www.caldigit.com/an-update-on-ts4-availability/

@@CalDigitHQ Thanks CalDigit. I have an older model but the new one will work better fir me.

Thanks for reaching out. There's currently no way to turn off the rear USB ports on the TS4.

Our TS4 only supports a host connection via the Computer port. You could do something like this with our TS3 Plus, where both Thunderbolt ports can be used as the host. The caveat is that you will have to unplug one of the host devices for it to adopt the other device as the host. Either way, you are going to have to disconnect one thing and connect the other.

High pitched noise is not normal. I recommend that you get in touch with our support team to get the behavior addressed. Here's some contact information: Email: Support@CalDigit.com Livechat: caldigit.com/support/

We're seeing some cases of Kernel Panics, but it's mostly only occurring when the computer is waking up from sleep, and only to some users. Specifically, we think it's related to the graphics driver on macOS, as the behavior seems to go away when no monitors are connected. We're working with Apple to get this resolved as quickly as possible and are hoping it's corrected in a future macOS update. Other than this case, the dock works great and should be compatible with your use-case.

We have seen some unwanted behaviors introduced in macOS 12.2 and earlier versions of Monterey in a small number of computers that has affected all Thunderbolt docks. Particularly, dual monitors do not always reliably stay connected. Again, this behavior does not affect all computers, we have had limited success in replicating it in our testing lab Additionally, there is a separate graphics related behavior that is affecting a small number of users. When a macOS computer is put to sleep in clamshell mode, some computers may crash when waking up from sleep. This behavior goes back a little longer, to Catalina, and has existed intermittently since on some level, it disappearing almost entirely on Big Sur before coming back with Monterey. This behavior can occur on any Thunderbolt dock with a monitor connected, and possibly USB-C docks as well. These are very niche cases, and the majority of users will not experience them. Some of the behavior seems to be isolated to a particular computer, where-in we have swapped out an affected computer with an identical one and the behavior has gone away in some cases. We expect that both of these behaviors will be cleared up with a future macOS update and we are reporting all of our findings to Apple to aid in expediting that process.

Yes, the computer will pick up Ethernet connected to a dock as hardline/ connected to the computer. MacOS likes to jump back and forth between all connected internet options, so to ensure it stays on Ethernet you should turn off Wi-fi if you're connected to the local network.

thanks for the response!@@CalDigitHQ

Yes, the M1 Pro lineup supports up to dual 6k 60hz with our TS4. Dual 4k60hz should be supported no problem!

The TS4 supports USB-C 10Gbps, so yes, it does support many more "older" computers that the TS3 Plus did not support. But the TS4 is not compatible with USB-A only computers, or the oldest USB-C computers with a 5Gbps connection.

Everything shares the single 40Gbps connection, but ports only utilize as much as they need. Beyond that, all the USB ports share a single 10Gbps USB BUS. Here's a breakdown of how the bandwidth allocation works on the TS4: www.caldigit.com/ts4-interface-bandwidth-allocation-and-diagram/

Three external monitors is not natively supported by Thunderbolt - only up to two monitors are supported normally. The only way to do this is with a technology called DisplayLink, which works by using a software program to drive additional monitors. This is a bit more work to set up than a normal monitor, so we don't include it in our docks. You can add the tech to any dock yourself with a USB DisplayLink adapter.

There can only be one host device at a time. So while you can technically connect multiple computers to the TS4, not much is going to happen. Some PC to PC or macOS to macOS connections can utilize Thunderbolt data sharing, but whether this is supported is dependent on the individual computers you are connecting.

The TS4 can only connect to a host via the "Computer" Thunderbolt port. Other Thunderbolt ports will not work.

You don't need to worry about that at all. Modern computers are pretty smart, and they are already prepared for this scenario. Basically, every time a charging device plugs into any modern computer, there's a sort of handshake that occurs between the computer and charger, where-in they come to an agreement on how much power will be passed on, if any. In a situation like your setup, the computer will always tell any connected devices not to give any power.

Sounds like it may be related to this known issue. www.caldigit.com/thunderbolt-dock-sleep-mode-related-issues-under-macos-12/ I recommend that you get in touch with our support team concerning the behavior. Here are some contact methods: Email: Support@CalDigit.com Livechat: caldigit.com/support/ Best regards, Dalton from CalDigit

It depends on the kind of drives and how much you already have connected to the dock. If you mostly have peripherals connected like a keyboard and mouse, and nothing that takes up a ton of data bandwidth, the drives are almost certainly fine to use without any performance hits.

No. USB 3.0 is too slow for the TS4 to operate effectively.

Yes, amongst other things, our engineering team is working on getting it migrated for full M1 support!

@@CalDigitHQ Still?! The M1 has been out for over a year. So hen do you expect it will world properly full M1?

@@adirkse I do not have an ETA at this time. Our Engineering team is balancing multiple projects and are focused on the TS4's release right now.

@@CalDigitHQ I understand. That's why I asked if these problems people have using the TS3 are solved with the new TS4... If not, buying it makes no sense at all.

@@adirkse I'm sorry, I think I misinterpreted your question. The first comment in this chain was asking about when our Docking Station Utility software will work natively on M1 devices instead of through Rosetta. All of our docks can utilize this same software. It sounds like what you are asking is specifically about TS4 compatibility with M1 devices. Overall, the TS4 is compatible with M1 devices. The largest unintended behavior we are seeing right now is related to the dock's behavior changing when the computer goes through a sleep cycle. The nature of this behavior has changed pretty drastically between each macOS 12 update, so we are working with Apple to get this resolved as soon as possible.

Thanks for the recommendation. I don't think that is currently possible with Thunderbolt tech, but it's definitely something we're interested in exploring.

​@@CalDigitHQ Apparently this is possible. The following docks have power buttons on them for easy switching on/off. Below are some examples with links: • Dell WD19TBS Thunderbolt 3 Dock: www.dell.com/en-us/work/shop/dell-thunderbolt-dock-wd19tbs/apd/210-azbi/pc-accessories • Anker PowerExpand 5-in-1 Thunderbolt 4 Mini Dock: us.anker.com/products/a8398 • Kensington SD5700T Thunderbolt 4 Dock: store.kensington.com/collections/docking-stations-1/products/sd5700t-thunderbolt%E2%84%A24-dual-4k-docking-station-with-90w-pd-win-mac?

@@27hdyx6b3ym3w Thank you for providing some some sources to provide your suggestion. My understanding is that both the Anker and Kensington docks you linked toggle power on the dock itself. This is definitely a feature that some users request and is within our ability to do, but for a variety of factors, our engineering team has opted not to include it in our products. I understand that what you really want is what the Dell dock is offering, which is an external power button for the physical computer. However, the button only works on compatible products, namely Dell computers (and probably not even all of them). I'm unfamiliar with the ins and outs of how this works, but I understand that there is no standardization for external power button support at all, if it's even a supported operation. My understanding is that no macOS computer even supports this function. Essentially, if we were to produce a dock with this feature, it would only work for very specific brands of computers. Computer manufacturers can get away with this because the docks they manufacture are accessories for their own computers, but we have take into account all possible computers in our products.

Dual 1440p 144hz should be supported and can work via either USB-C or DisplayPort, as long as the cable is rated for DisplayPort 1.4 165hz is maybe possible, but that's definitely pushing the limit of the dock. We have not had the chance to test with this configuration yet.

Sounds like you may be experiencing coil whine. This is usually caused by the power supply, and addressable with a replacement. We've seen a few cases of this behavior, and we're looking into changing PSU suppliers in the long term to address this concern. In the mean time, I recommend that you get in touch with our support team, who will be able to help you with a solution to this behavior. Here's some contact methods. Email: Support@CalDigit.com Livechat: caldigit.com/support/

No, not with our TS4. You have to use the host port to get a connection. Here's some additional info on charging in case you're curious: If you plug in another charger to the computer, like the charger that came with your computer, the computer will only accept charging from one source. Generally this is the computer's charger itself. Additionally, most modern computers utilize some kind of battery conservation technology that makes keeping the charger plugged in at all times safe for the battery. Some common techniques are slowing charging down to a trickle as the battery approaches full, and bypassing the battery entirely to pull power straight from the charger when the battery is at full. Hope this helps!

@@CalDigitHQ it does- thanks!

The TS4 works with USB-C 10Gbps. If the port you have is charging only, it won't work. The USB-C port also needs to support DP-alt mode or DisplayPort in some way for video to function. Ethernet also will also likely not work on a USB-C connection.

Definitely, you can do that either with a USB-C to HDMI adapter or with an Active DP to HDMI adapter.

@@CalDigitHQ Awesome! Thank you!

Looks like your particular monitor can only push 4k 144hz out of the HDMI 2.1 ports. you will need an adapter that supports HDMI 2.1. As you tried the DP port with an adapter, I would recommend you go for a USB-C Adapter.

@@CalDigitHQ Many thanks for your reply. I've been testing directly with a USB-C to display port cable from my Macbook to my monitor and for my surprise, it did not work ... After that I guess it has to be an issue between my model monitor and macOS. The TS4 shows the same behavior that if I connect the monitor directly to my Mac, so no issues with the TS4.

@@adolfofernandez9517 If you haven't yet, try a USB-C to HDMI cable. Like I mentioned before, I believe full resolution and refresh rate on your monitor is only supported via the HDMI ports. Just make sure it's USB-C to HDMI 2.1.

No. However, if the concern is about degraded battery life, that's a non-issue. Modern laptops utilize a wide variety of battery conservation techniques to maintain long healthy battery life. Modern MacBooks all implement slower trickle charging as the battery reaches full, and many will bypass the battery entirely if a power source is plugged in when the battery is full.

Thank you 😊

No, the utility cannot do that. You'll have to either physically reconnect and disconnect the affected drives or the whole dock to repopulate the drives.

If everything is already set up, you can find refresh rate in "System Preferences" and then "Displays". Select your monitor, and "Refresh rate" is towards the bottom of the menu. If you can't reach your target refresh rate, there may be something wrong with the connection. In that case, I'd suggest you start by replacing cables. Both the DisplayPort cable and Thunderbolt cable would be good to replace. If the Thunderbolt cable is one of ours and turns out to be at fault, our support team would be happy to replace it. Also, check your monitor's physical settings and check if you have a refresh rate option in there - some monitors can limit refresh rate this way.

Yes, the M1 MacBook Air is supported with our TS4. Do note that the M1 MacBook Air only supports a single external monitor via Thunderbolt connection, so if you want additional external monitors, you will need to use DisplayLink.

Yes, it can be! Over a Thunderbolt connection it should work flawlessly. Over USB4, Ethernet may or may not work, and over a USB3 USB-C connection, Ethernet will not work and only one monitor will work.

Yes, with limited functionality. USB-C connections are limited to 10Gbps bandwidth, versus Thunderbolt’s 40Gbps. USB-C connections also can only support a single external monitor at a time, and the Ethernet port will likely not work.

Yes, that's possible, but it does have to be plugged into the included power brick.

Thanks for your feedback. We experimented with adding CF Express, but ultimately opted against it for this release. Maybe in the future!

The few reports I've seen that are at all related to the behavior you are reporting has been seen across all Thunderbolt 4 docks, and it's been seemingly introduced with Monterey. Our engineering team is working diligently with Apple to resolve this behavior. In the mean time, we recommend that you keep macOS up to date.

I thought it was a Monterey issue too, when my Caldigit TS3 plus had issues. But it’s not, it might be an issue with Caldigit. Here’s how I figured it out. I purchased a Satechi Thunderbolt 4 dock and it worked flawlessly with my MacBook Pro M1 Max with Monterey. I really like my Caldigit TS3 plus with all its connectivity, so I didn’t want to let it go. I then connected it to one of the Thunderbolt 4 ports of the Satechi dock and now it works perfectly. The monitors wake up and the external hard drives stay connected. So I am happy to use my TS3 plus thus way. I am wondering if this is some hardware handshake issue. I say this because I tried the sonnet echo 11 Thunderbolt 4 dock, which seems to be a clone of the Satechi and my external drives kept disconnecting on wake. I then purchased the Satechi on a whim, and it worked! It even made my Caldigit TS3 plus which was connected to it work. Hope this helps.

@@RM-hy4so Thank you for your feedback. In our testing, we've found that swapping the dock or computer may alleviate the behavior, suggesting that the computer is taking issue with a particular connection that it then remembers, like the hardware handshake you reference. To my knowledge, this behavior indicates a wider Thunderbolt connectivity related behavior. In any case, it is something that our engineering team is working with Apple to resolve. We recommend that you stay up to date on macOS in the mean time!

@@CalDigitHQ You might be right about Thunderbolt connections and protocols being inconsistent. I am wondering if Thunderbolt cables also have a role in this issue. Certainly I seem to have benefited by luck. I was surprised that 2 similar docks (Satechi and Sonnet) behaved slightly differently, with the Satechi working flawlessly. I used the same Thunderbolt port on my M1Max. I really like the Caldigit TS3 plus and am delighted that I can now use it again connected via the Satechi. Please consider adding the optical connection again to the TS4 successor.

@@RM-hy4so Thunderbolt cables are definitely another possible factor, at least in general connectivity! We've seen some parts of the dock just fail to work because of an improper Thunderbolt connection. Swapping out a cable, or even just reseating it, can correct the behavior. Thanks for your feedback on the optical port! We'll definitely be considering it!

I believe the M1 Max and Pro both have individual BUSes for each Thunderbolt port, so yes, you should be able to and get full speeds. Do note that you will only be able to get up to 4 monitors total if you do this, which you could also accomplish with 2 TS4s.

@@CalDigitHQ Thanks for the reply. Actually i am planning to run 10 monitors by using startech dual adapter displays which can turn 1 display output to 2 additional display. There is a video in which the guy attached 4 external displays to macbook air m1 which only supports 1 display, the title of the video is something like 6 display with macbook and mac mini. He used one caldigit ts3 and two startech dual adapters which according to him has an builtin vga s in them. In theory if one port of macbook air m1 can run 4 displays with this setup, then m1max has 3 thunderbolt ports, and one hdmi, so 4 startech dual adaptors for 8 displays, attached to 2 ts4 four display outputs combined, and 2 ts4s to two mbp m1max two thunderbolt ports, and then we are left with 1 spare tb port and 1 hdmi..... they can run 2 for total 10 monitors setup. Don't know if it will work.... if we utilized 3 ts4s for 12 monitors and 1 hdmi for the 13 that should work too. but it messes up the monitor wall array, i need one monitor in center configuration. so it can be 6 for 2 rows of 3, or 9 for 3 rows of 3, or 10 for 2 rows of 5 or 15 for 3 rows of 5 horizontally . btw i trade financial markets and i need like 200 charts open at the same time in front of me. So its a real need. and problem with having multiple computers is cant sync the work. desktop cant go out with me, so i need one laptop that runs all this on display wall when i am at home, and on laptop when i am traveling.

@@latesttechtrends1227 I'm familiar with a video that sounds very similar to what you are describing, but the magic sauce was that they were using DisplayLink adapters for additional monitors. This would be your best bet for the amount of monitors you are looking for. DisplayLink bypasses the Thunderbolt monitor limit by operating the monitors via the CPU instead of the GPU. With this method, you could theoretically get as many monitors as there are USB ports available - so up to 11 monitors on a single TS4 (including the 2 supported via Thunderbolt). The downside of this method is that it can introduce unwanted behavior to the computer, and may cause additional computer load at idle. We don't officially support it, so I really couldn't say what kind of performance you can expect. But with that many monitors running of the CPU, the computer would definitely be under continuous strain, definitely more than usual.

@@CalDigitHQ Thank u again for ur time dear. You are absolutely right about display link. The two different displaylink adaptors he used are one from startech and one from plugable. and he says that startech is better. Software he used is display link manager. The only thing is he was only able to use 5 monitors with the mb air m1, not 6. Which tells me that somehow the limit being mb air m1 only supports 1 external display. He also ran all 6 with the activity monitor on for performence. here is the link on that video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Kq_FyjcAULA.html&ab_channel=RuslanTulupov title: Six Displays Running on M1 Mac Mini, Macbook Air + Activity Monitor + Subscriber Q&A #WorkFromHome Can you please look at it and then tell me if 2 caldigits ts4s and 4 startech adaptors give ma 10 monitors setup on m1max.

Big Sur is the first macOS version to support Thunderbolt 4. Previous versions, such as Catalina, cannot support the TS4 because they have no way of understanding what the TS4 is.

@@haroldson5 We've been seeing macOS Ventura misbehaving a bit with Thunderbolt docks. We're analyzing cases that come in and send to Apple with our findings, so we're hoping an update to macOS fully corrects this behavior. In the mean time, there are some workarounds. The major one is changing the DisplayPort version on your monitor's physical settings. We've mostly tracked this monitor misbehavior to DisplayPort 1.2 monitors, so changing your monitor to DisplayPort 1.4 or 1.1 may help alleviate this behavior. Beyond that, we also recommend trying a different DisplayPort cable if possible. Sometimes unshielded or internally frayed cables can introduce behavior similar to what you are describing. If you are converting from HDMI to mate with the TS4's DisplayPort, please also make sure that you are using an Active DisplayPort to HDMI adapter.
