The TS4 uses an Intel ethernet controller so Realtek drivers won't work here.
Caldigit tweeted that they'll be releasing a firmware update for the TS4 later this week, so perhaps this will solve some of these issues.

Caldigit tweeted that they'll be releasing a firmware update for the TS4 later this week, so perhaps this will solve some of these issues.
I now have a TS4 as well as my older TS3+.
I'm currently trying to use it with my new Mac Studio M1 Ultra.
I have two USB hubs, one a Sabrent hub, and the other an Amazon basics. Attached to the hubs are various MIDI controllers, software dongle lock USB sticks for music software, etc.
If the hubs are connected to the TS4, they don't work at all. None of the USB devices show up in "Apple -> About This Mac -> System Report -> USB". If I swap out the TS3+ in place of the TS4, the hubs work just fine. If I connect the hubs directly to the Mac Studio, they also work fine.
Individual USB devices seem to work OK when connected directly to the TS4 (like USB flash drives, external disks, etc.).
But the hubs? Nope. Frustrating.

My only point of reference are a Kingston TB3 dock and an OCW TB4 hub, they both worked with USB hubs attached.
I was really interested in the TS4 because of the amount of ports it offers, but so many people are having weird bugs and issues with it. This is becoming statistically significant to ignore. Something is fundamentally wrong with the TS4 that prevents it to work correctly with mcOS. Hopefully all these bugs can be addressed by a firmware update, the TS4 is unique on the market.

Do the hubs have their own power supply? Did you test the hubs with all the ports of the TS4? Including the two downstream Thunderbolt ports?
What if you connect the TS4 to the TS3+? Do the hubs work connected to the TS4 in that case? Putting a Thunderbolt 3 device (the TS3+) between a Thunderbolt 4 device (the TS4) and a Thunderbolt 4 host (the Mac Studio) disables the USB tunnelling feature of Thunderbolt 4/USB4, forcing the USB controller of the TS4 to be used instead of the USB controller of the Thunderbolt 4 host.
Yes, there are powered USB hubs.
I tried a few of the Type-A ports on the TS4 (not sure I tried every one).
That's interesting about the Thunderbolt 4 tunneling. I received a response from CalDigit support which kind of alluded to something along those lines, that the Thunderbolt 4 protocol itself won't allow hubs to be connected to the dock, but that Thunderbolt 3 allows it.
I just noticed that if I try connecting my Dell monitor to the TS4 (via USB), then it's USB hub doesn't work either.
Seems like what CalDigit support said is true. No USB hubs off the TS4.
I was able to move things around so the hubs are all connected directly to the Mac Studio. Thank goodness it has so many ports!

Caldigit has released the Windows version of the firmware updater for the TS4, with this note:
Code:
This firmware v.39 is to resolve sleep and device ejected issue observed in Apple silicon computers. macOS updater will be released on July 6th, 2022Same issue here, I have two 1440p 160hz monitors, not 4k ones. On my TS3+ both works fine on their max resolution and frame rate using DP to DP and DP to type C.
Silly of me moving to TS4 just for the ethernet upgrade.... Now I have the issues others have mentioned here and my dual display which uses the thunderbolt downstream does not exceed the 60hz mark. Sometimes it goes to 120hz but upon wake to sleep it reverts back. What a waste. Support is responsive but is just throwing away stuff that doesn't explain the scenario.
Exact same setup on 16in M1 Max, same cable, same monitors, just the hub was swapped.
They released a windows software updater to resolve issues on mac computers?
I'm guessing they did this in order to get the firmware update out faster. But it kind of indicates that they don't have the right developers on this issue.
Are way able to update the firmware via Parallels?
I had to completely refresh the page to see the firmware download link. If you have trouble finding it, here Windows Firmware Updater 5.0. From ReadMe.txt:
You'd need to use Boot Camp to update, or wait until next week to get the Mac updater.
Hmmm, yes, I saw the update on your site. I used my windows work laptop and updated with the bin for TS4 using that laptop.
After rigorous testing and a lot of cable configuratios the behavior on my end now — the refresh rate does not get changed after a reboot. What “refreshes” or fixes it temporaririly is if I use also a DP to type C on my DP to DP monitor. Then the other monitor would go high up as 120hz, but still not the 165hz it was able to do with the TS3+ setup that I have.
Steps to reproduce
- Wake from sleep M1 Max
- Check display settins, DP to DP > HDR unlocked and 180hz
- DP to type C > only 60hz
- Change cable on DP to DP monitor into DP to type C
- AND then change/switch thunderbolt port on macbook (won’t work if a reboot or power cycle with the TS4)
- See the refresh rate still unlock again for DP to type C 120hz
- Now switch back to DP to DP and DP to type C, I still have the 180hz and 120hz working
- Put to sleep again, and see the same behavior happen
This is the most reproducible scenario where I see the issue is happening.

Exactly which displays do you have? Do either of them support HBR3? If so then one might connect at HBR3 which leaves the other at HBR2. Do they have a DisplayPort 1.2 switch that you can enable?
160Hz would require 8bpc for HBR2 and would not allow HDR unless DSC is supported.
If a display has a USB-C input, then USB-C connection might connect as two lanes instead of 4 unless the display has a prioritize resolution/refresh rate option.
Two lanes of HBR3 is only 75% the bandwidth of 4 lanes of HBR2, so a four lane HBR2 connection for another display can be supported.
For modern displays that support HBR3, you need to be aware of the bandwidth limits of a Thunderbolt dock when connecting two displays.
On an Intel Mac, you can use AllRez to check the DisplayPort link rate and link width. I would like to update the code to work on Apple Silicon Macs one day. It would take some investigation to find an API to do DisplayPort DPCD communication, but people have done similar investigation to do I2C communication.
It's these two
This is the DP to DP monitor https://www.lg.com/us/monitors/lg-27gp850-b-gaming-monitor
This is the DP to type C monitor https://www.lenovo.com/ao/en/monitors/G27q-20
On my TS3+ setup both I can use with HDR on with 165hz. Both are DP 1.4 capable I believe, the LG (DP to DP)does not have a toggle, the Lenovo(DP to thunderbolt 4 downstream) does have the toggle but on spec sheet it does say it's DP 1.2 but I can toggle between 1.4 and 1.2
So what should I do or test?
Use DP 1.2 on the other? or switch the cables I used? The LG is my main display hence I used DP to DP.
Update:
Switched the cables from both monitors, used DP 1.2 on the Lenovo one, now uses DP to DP. The issue is still persistent with now the LG locking to 60hz using the downstream port.

The LG User Guide says the 27GP850 and 27GP83B/32GP83B have a DisplayPort version switch.
Set both displays to DP 1.2, disconnect them. Power off. Connect. Power on. Do you get expected behaviour then?
If not, do you get expected behaviour when the TS3+ is connected after the TS4 and the displays are connected to the TS3+? If yes, then maybe you can use a Thunderbolt to Dual DisplayPort 1.2 adapter? (make sure the adapter is Thunderbolt and doesn't support DisplayPort 1.4).
Unfortunately, the latest releases for this model so far has this setting greyed out, well, at least for my usage on my mac. I would try on my windows if I can switch that but honestly, I can't remember.
Also I don't have the TS3+ anymore since I sold it....... The adapter approach is something I haven't tried I have always used a USB C to DP which was working before on my TS3+ setup
UPDATE:
Well, I managed to change the DP version on the OSD from my windows machine and hooked it right back to the TS4. Both of the monitors should be running DP 1.2 right now. Did the restart and all. I've put the laptop to sleep, woke it up and the 60hz on the other came up again.

To those that updated to the latest firmware, and you happen to have a USB-C monitor connected to the TS4. Is it now working?
I have a USB-C monitor connected to the TS4, that the video signal is not working but the data is. I am able to use the USB-hub on the monitor, although it is not displaying anything and it's not identified in my Mac. Whilst googling around on reddit - I have read that Caldigit is aware of this issue, and said they'd be resolving it in a firmware upgrade.
The TS4 is replacing a TS3+ in exactly the same setup. I did not have any issues with the TS3+, - but the TS4 seems to give grief similar in particular with the ethernet connection, which hopefully the new firmware to solve.

1. TS4: Firmware v.39 Fix:
1.1. External monitor connected to TS4's USB-C port (next to DisplayPort) through USB-C dongle might not be recognzed on resume from host sleep.
1.2. USB and Thunderbolt devices might be ejected randomly on resume from the sleep mode when Mac is with Apple Silicon and macOS is 12.3 or above.
1.3. macOS might crash and restart randomly on resume from the sleep mode when Mac is with Apple Silicon and macOS is 12.2 or below.

Didn't Caldigit blame Apple and macOS in the first place all the time?
Why all of a sudden things can be fixed with a firmware on their site while most TB4 docking stations from other vendors worked fine the whole time?
We all know what I call this...
Staying with my TS3+
Nonetheless I'm eager to read some reports here.

It's a half-baked product - launched the hardware prior to developing the firmware for it to run properly. Done in order to capture some market share before its customers buy other products that are working. Waiting patiently for this firmware upgrade, and in the meantime, i'm back to using the TS3+....
I would like to connect the display studio and a 32" DELL Display (via USB-C) and looking for a thunderbolt dock.
Would you recommend this? Seems to be the only dock which supports connecting a 5K Studio Display and a 4K Display? Or do you have other recommendations?

Try to check to see whether it'll work with your Dell 32" USB-C monitor - right out of the box, or wait to see the feedback after the recent firmware upgrade. If it works, - then it's good to go ahead with it. Else, you'll probably be waiting for future updates to the firmware until it works. I'm confident that Caldigit will eventually get the firmware right to be compatible with USB-C monitors, but for now, - some work and others' don't. No issues with thunderbolt monitors though!
I have it connected with an Asus USB-C monitor (Pa329C), and it doesn't work. Currently waiting for Caldigit to release their firmware update for OSX to apply it to the unit and see what happens. The DP port works fine, and connecting it to TB monitors is fine.
Alternative docks, perhaps OWC's or Razer TB4 docks may work.
