I am done tolerating the issues. I only have the ethernet plugged in, power and display port screen. And the network stopped working again. I am sending it back for a refund. I am not sure I will deal with Caldigit again. Their support lately has been terrible and slow. I will have to find another TB4 dock to replace it with. Or just use my trusty TS3+.
Got a tip for us?

Caldigit TS4 Dock

Been using this dock for a few days and is working great for me. I too experienced the “Ethernet” issue, but I manually switched it to full-duplex mode, and it works great. I am thinking this has more to do with my 3 year old FiOS router than an issue with Caldigit. I think the 2.5GBE has some fancy features on it that my router can’t handle. I just did a 1 hour Microsoft teams call with it, and I had no issues at all

I have a 24 port switch it goes into. And I changed those settings and still having it stop working. Not pleased. Ts3 plus worked great. I’ll send it back and use it for now.
Well, working with this setup: MBP 14" M1 Pro Max -> TS4 -> XDR & UltraFine 4K....
It works, but the cursor is a bit jerky and there are random flashes. I really think it may be too much data pushing through the pipe, but I have no way to test it other than to plug the 4K directly into another port on the MBP to see if there is a difference. I love the one cable setup, but maybe I'm asking a lot of 1 device. I'm sure once I turn my camera on adding even more data down the pipe, things will get worse. Am I the only one running with an XDR + additional monitor through the TS4?

Adding to this -- running through the TS4 and waking up from sleep puts the Ultrafine into 1080x1920 mode (I'm running portrait). I have to unplug it and replug it in to make it see it as retina. My dream of one wire running into the MBP is fading...
A followup to my earlier post about my 7-port hub not fully working (only 3 of the ports work, due to the other 4 ports being an additional internal "hub" which, along with the TS4's own chain of internal hubs, puts those last 4 ports over the USB hub chain limit, despite being the only physical hub in the "chain").
I had previously mentioned that adding a 4-port hub, connected to one of the Thunderbolt ports, allowed me to then successfully connect my 7-port hub to that hub. But I also discovered that the two USB-C ports on the front panel are higher up on the USB device tree, so the 7-port hub works fine when connected to one of those (just had to buy a USB-C to USB-B cable). Presumably that cable would also let me directly connect that 7-port hub to the Thunderbolt port, but I didn't try that... previously used that 4-port hub (which has a USB-C host connection) to get the 7-port hub operational because it's just what I had on-hand.

It's usually a good idea to connect devices (one USB 1.1 or 2.0 and one USB 3.x) to all the ports to map the internal layout of the hubs so you know which hubs will have the best performance. Use IORegistryExplorer.app to see how the hubs are connected to together and to see all the ports for each hub. Actually, if someone could post a screenshot of that (or output from ioreg), it would be interesting.
In the picture for the CalDigit TS3+ at https://www.caldigit.com/ts3-plus-interface-bandwidth-allocation-and-diagram/ you see there are 4 different groups of devices, each group is a PCIe 3.0 x1 connection to the Thunderbolt controller's PCIe switch. The TS3+ has no USB hub internally - just 3 USB controllers (two with 4 ports and one with 2 ports), and an Ethernet controller. The downstream Thunderbolt port is its own 5th group supporting PCIe 3.0 x4 up to 22 Gbps + DisplayPort.
For the TS4+ you'll see there is a USB Hub (one group), and USB hubs connected to that (separate groups but sub groups of the main hub). The Ethernet port is handled by a PCIe Ethernet controller which makes its own group. The downstream Thunderbolt ports are two separate groups like the downstream Thunderbolt port of the TS3+.
Thanks. That's from an M1 Mac. The TS4 is connected to the M1 Mac's USB controller using USB tunnelling so the PCIe Ethernet device is not shown.
I think this list is missing some ports that don't have anything connected to them. Since it's not a full window screenshot, I can't be sure what you're looking at. Looking at the location @ hex strings, I think the list is more like this:

@02244000 MiniPro RAID V3The next step is to remove all connected USB devices so you're only left with the TS4. Then for each port (one at a time), connect a USB 1.1 or USB 2.0 device (such as a mouse or keyboard) and a USB 3.x device (such as a thumb drive). Then add the description of the port to the list above. So maybe @02220000 and @02120000 are "left downstream Thunderbolt port" or something like that.
Took a read of this chain and the less than stellar discussion I had with CD support last week and went with the Anker 577. It's over £100 cheaper and doesn't seem to have anything like the issues in here.
Has anyone had issues with the TS4 not appearing as a Sound device?
I have it on my Mac Mini (Intel 2018 version) currently in anticipation of my M1Max MBP coming in a couple weeks. The TS4 seems to work with its DP port and other things but I am not seeing it in my Sound options for either an input or output.

I’m not seeing it as a sound output either, but my assumption has been that maybe it doesn’t show up unless something is plugged into one of those ports (which I haven’t tried).
Turns out the TS4 is working fine. I think the audio cable from the speaker to the dock was bad, I replaced it and it is working just fine now.
You are correct in that it does not appear unless there is something plugged in.
I have both the 6K HDR and the 5K LG Ultrafine running from a TS4 with one cable to one port solution on a MBP M1 MAX, and both appear to display OK to my untrained naked eye. How do I check if I am getting the 5K and 6K resolutions? I have many more things to test before I can say TS4 is working OK, but so far with 4 storage devices (HD and SSD) scanner, label printer, 4K webcam, speaker
I have connected both the HDR 6K and the LG 5K with a one cable solution and to my untrained naked eye both look ok and appear to function. How I can I check if I am indeed getting 5K60 and 6K 60? I have several other items to check before I can say my TS4connected to a MBP 16" M1 MAX, is all good, so far, 2 SSDs, 2 HD, scanner, label printer, speakers, ethernet (with the suggested change to full duplex), DVD writer, 4K webcam, seems OK. No crashes so far after placing the MBP on sleep - however I just set up this a few hours ago.
If you run SwitchResX, and double click the current resolution of each display, it should show the active pixels (width and height) along with other timing info (pixel clock).
In your case, the 5K display will show 4K with 500+ MHz pixel clock instead of the desired 5K 900+ MHz. The 6K display should appear as 6K 1200+ MHz.
On an Intel Mac, you could use the AGDCDiagnose command.
/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a > AGDCDiagnose_a.txt 2>&1but that doesn't give display mode info for Intel, Nvidia, or old AMD GPUs.
You have an M1 MAX, so you can't check the output of the AGDCDiagnose command. In that case, ioreg may have the info.
ioreg -fliw0 > ioreg.txtThere's a lot of info in there. I made a couple scripts to get just the display mode info from the ioreg output.
https://gist.github.com/joevt/e862b0088ef58b9144877d01401bcee8
https://gist.github.com/joevt/0c75b42171b3fb1a5248b4e2bee8e4d0
I think the first one is a faster method but I haven't tested it with ioreg from M1 Max/M1 Pro. Let me know if there's an issue and I'll update it (attach a zipped ioreg_M1.plist file).
I'm working on a utility to get more display info. I haven't had anyone with an M1 Mac try it yet. It should be able to get display info from ioreg but I haven't added code to display that info in a more compact form like in the above scripts. On Intel Macs it can get DisplayPort info, EDID, and DDC/CI MCCSS info.
#177
~/Downloads/AllRez > allrez.txtI'm considering adding a TS4 to my setup. I need to be able to run all of the below concurrently via a 16" M1 Max:
- LG Ultrafine 5K (TB3)
- 1GB ethernet connection
- Blue Yeti X USB mic (USB 3)
- Logitech Brio webcam (USB 3)
- Sony ZV1 connected via Camlink 4K (USB 3)
- Keychron keyboard (USB 3)
Thanks Joevt. Ran SwitchResX. It appears that I am not running my screens at the MAX supported resolutions of either as it is. I need a bigger image and text. With one cable the HDR shows at 3008x1692 @ 60hz (with MAX supported at 5120x2880 @ 60hz) and the LG5K is at 2560x1440 @60 (matching the image size on the side by side HRD), with a max supported of 4096x2304 @ 60). If I switched both to the max resolutions on SwitchResX they work - but the text becomes too small for my use. So clearly one cable will support both with the 5K LG limited to 4K as you explained, but for my use and preferred resolutions it works. Should I need to MAX out both I would have to plug one of these to another thunderbolt port. Again, thanks for the eloquent explanations. So far my TS4 is working fine. No crashes, and all devices working
I don't have the same devices you have, but I have all of the following, and as of now my TS4 connected to a MBP 16" M1 MAX is working fine. MPB has been rebooted and gone to sleep without issue.
* 2 Sandisk 2TB SSDs,
* 2 USB 3 Hard Drives
* Fujitsu USB Scannerscanner
* Brother USB label printer
* external Bose speakers, connected to back port
* 1GB ethernet (with the suggested change to full duplex WITHOUTH the energy efficient option),
* Sony USB DVD writer
* Logitech 4K WEBCAM for HDR (Brio equivalent)
* APC power backup connected via USB
* Apple HDR 6K 32" Monitor - MAX supported at 5120x2880 @ 60hz (on t4 port)
* LG 5K Ultrafine 27" Monitor - MAX supported at 4096x2304 @ 60 (another T4 port) (for full 5K support needs to be connected alone without HDR or on another T4 port on the MBP)
Some USB items connected to TS4 via an ANKER plain powered USB hub. So far the power delivery on clamshell mode has maintained the charge without issue - no need to use the magsafe Apple charger.
Not the same, but mine should work then. Thanks likegadgets, I'll give it a try.
that happens with my OWC hub as well, so I guess some sort of thunderbolt 4 issue either with the Macbook or the hub/dock.
I wonder if someone could come top with a app that could quickly disabler enable the thunderbolt ports after waking from sleep?
You have not provided sufficient information to determine the actual mode that is being output to the display. I told you to double click the current resolution of each display to see the pixel clock and active pixels. Did you not try that?
There are six different ways that the 3008x1692 resolution can work:
1) 3008x1692 HiDPI with 6016x3384 active pixels (this is probably what you are seeing and is the best option - there is no GPU scaling involved - HiDPI means everything is drawn twice as wide and twice as tall compared to a non-HiDPI mode)
2) 3008x1692 HiDPI scaled up to more than 6016x3384 active pixels (does not apply to your case - someone with an 8K display might get this option if 8K actually worked - the frame buffer is 6K so must be scaled up to output 8K)
3) 3008x1692 HiDPI scaled down to less than 6016x3384 active pixels (someone with a 4K or 5K display might get this - since you have a 6K display, this option will only occur if the GPU is not sending the best signal)
4) 3008x1692 with 3008x1692 active pixels (this mode has no GPU scaling - a 4K or 5K or 6K display will perform its own scaling - this mode is not likely to appear by default - it requires a custom timing)
5) 3008x1692 with more than 3008x1692 active pixels (this is a low-resolution or non-HiDPI mode that a person with a 4K or 5K display might get)
6) 3008x1692 with less than 3008x1692 active pixels (this is a low-resolution or non-HiDPI mode that a person with a 1440p display might get)
Non-HiDPI modes don't usually appear in the Displays preference panel unless you enable "Show all resolutions" (except the 6016x3384 6K mode is probably not HiDPI).
The above is also true for 2560x1440 (just replace 3008x1692 with 2560x1440 and 6016x3384 with 5120x2880). In your case you'll probably see that you are getting option 3: 2560x1440 HiDPI scaled down to 4K. The 5120x2880 mode is probably a non-HiDPI mode scaled down to 4K.
Clearly this is not my field. Attached are screen grabs of what SwitchResX outputs. 1st the LG 2nd the XDR
It's as expected. The 6K is working at 6K but the 5K is working at only 4K. The 5K needs to be the only display connected to a Thunderbolt bus in order to get 5K 60Hz.
M1 Macs have one Thunderbolt bus per Thunderbolt port.
Intel Macs have one Thunderbolt bus per two Thunderbolt ports.
In the screenshots, the "Scale to" is the size of the frame buffer (it should actually say "Scale from"). The "Active" is the number of pixels being transferred to the display.
In the 6K case, there is no "Scale to" because the frame buffer size matches the "Active"/output pixels size.
