Dell, where did this TB16 come from?

Q: Dell, where did this TB16 come from?

I happened to look out on my front entrance way and saw a package laying there. I brought it in and noticed it was from Dell. Well I had not ordered anything from Dell. I opened the box and saw it was a TB16. I do not know why I was sent this but here is my guess. I had ordered a TB15 over a year ago. After all the issues I had with it as well as others have had with it, I returned it before the 30 day return deadline. Now unannounced and over a year later, this TB16 shows up. Is Dell sending these out to people who returned the TB15's?
I don't know if I want it. People are still having issues even with this newer version. Whether this dock or any dock will work with the XPS 15 9550 is another question. It seems that even with the latest firmware/drivers installed, people are still having problems with the new version. I have my eye on another dock (Plugable Thunderbolt 3 Dock). It does not have all the bells and whistles of the TB16 but it has enough for me. Its release has been delayed for over a year. They won't release it until they know it works which is what Dell should have done.
So Dell what is going on here?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I agree releasing half-products is not fair. Considering that all vendors seem to have big TB3 issues, I guess Intel is to blame too.
But why not give it a try if it is free, and you're considering a dock anyway? ;)
I don't think everybody is having issues with the TB16. Some even made the TB15 work eventually, taking care of excess heat themselves. But according to a writeup at Plugable, some XPS have issues with their docks too. My WD15 works fine now, but it took firstly a bunch of updates and secondly the replacement of the DW1830 with Intel 8260.

I've bought TB16 and update all drivers (Dell Assist does it) and after lowing network settings to 75% my DELL monitors flickering less but now I have major issue since my Dell Adapter - USB-C to HDMI-VGA-Ethernet-USB stop working completely. When I plug in nothing happens (yes, adapter is working properly and yes cables are correct)
In first few days, randomly, Windows was enable to turn on output to adapter (after hour of plugin, plug out same adapter).
Now, it's completely useless. 
Can anyone help, any suggestion ?

Yeah I know, not officially supported. However I have my TB16 operating 90% effectively with a Metabox/Clevo P750DM-G (Sager NP9758G). Hoping to get some help with the last 10%...
I have two ASUS 27in 2560x1440 monitors operating in extended desktop mode, daisy-chained via DisplayPort, with the laptop monitor disabled. When connected to the TB16 via DisplayPort, both monitors operate however they seem to be displaying at the native resolution of the laptop screen (1920x1080), stretched to fill the 2560x1440 native res of the monitors, with accompanying slight distortion of text etc.
CPU i7-6700K, graphics GTX 980M. Apparently this machine does not make use of the Intel on-chip graphics, and I'm unable to install the latest Intel graphics driver ('This computer does not meet the minimum requirements for installing the software').
Any suggestions as to settings I should tweak or drivers I should install are welcome.
Footnote: Purchased the TB16 with my eyes open and half-expected it not to work, however am pleased to report that it functions as advertised. Even this DisplayPort issue isn't a showstopper.

Hi All - I just got a TB16 to replace my old USB3 dock that had dead USB ports on it. I have followed the information in the TB16 setup guide, the driver installation guide and tried a lot of different things. The TB Controller is enabled and security is disabled in BIOS. I also turned on all the checkbox options in BIOS, and have toggled them on and off to make sure they are actually turned on. 
None of the USB ports on the new TB16 work, the sound ports do not work, and the NIC does not work. I am able to get the display ports working (using both right now, connected to USB powered Dual-Link DVI adapters connected to my good old 3007WFPs).
I have tried several "down rev" versions of the USB controller driver that is provided by Dell. I cannot even see any evidence of USB devices when the TB16 is connected with the 240W power adapter connected. However, if I unplug the 240W power adapter from the TB16, I do see some USB devices pop up, but they don't work. I have tried leaving the dock disconnected from everything for 4 days and then connecting the power adapter to it, then connecting the laptop. That did no good either.
I also tried using the recommended "disable WiFi" fix that was posted here in the forums. That made no difference. It makes no difference if the laptop is off and powered up with the lid closed or with the lid open. I also cannot use a USB keyboard connected to the TB16 on the bitlocker prompt screen, regardless what port it is c... Read more

Hi guys,
Apologies if this has been posted elsewhere (though I haven't been able to find anything). I'm testing a TB16 dock for use with the Latitude 7480 but cannot get it to work with the monitors. it is supplying power to the laptop, but nothing else plugged into it is recognised. I have updated all the available drivers for the 7480 and the BIOS is updated to 1.2.9.  The BIOS was updated first.
When I attempt to install the  Thunderbolt 3 Firmware update, I get an error that "No Thunderbolt controller update supported for this platform ID=0x7A0".  
I have installed the available thunderbolt drivers listed here in addition to the Thunderbolt Software
I'm running Windows 10 Pro version 1607 Build 14393.953
Short of uninstalling all the drivers and reinstalling in the right order (again), I'm running out of ideas, so any help would be appreciated.

A:Dell 7480 and TB16 dock

I don't know about that particular machine but the TB firmware and controller are installed to the machine before you even plug in the dock.
If the Thunderbolt options in the Bios are greyed out, you do not have a Thunderbolt controller.  I will leave it to you as to whether you have a 2 or 3 lane Thunderbolt system.

Is anyone else having performance issues with the Dell TB16 and Latitude 7370's:
Slow keyboard and mouse response, delayed typing, garbled audio with Windows sounds \ Skype calls, slow application response with ALT+TAB, accessing network resources \ shares is extremely slow and just flat out overall poor performance.
I am having this issue with several of these docks and I have done the Dell OSD Driver CAB version A08 for the Latitude 7370, installed the TB16 drivers manually and even tried the Dell Command Update Utility to no avail.
At the time of this poor performance if we unplug the TB16 everything goes back to expected performance, also worth noting if we work with only 1 monitor connected to the TB16 there are no performance issues.

Same issues with the Dell TB16 as with the TB15???
The TB16 is not the fix I was expecting after all the issues with my2016 TB15. Last year which I managed to get a full refund for from Dell. My new TB16 arrived last Thursday, and initially when I plugged it into my XPS15 and everything worked fine (for a little while). Now I cannot get my HDMI and DP screens to work at the same time, it's one or the other, the USB ports are intermittent and its hit and miss whether the TB16 charges my laptop, if I touch the TB16 or lightly brush the Thunderbolt lead, I lose Ethernet, charging or the one screen I've managed to coax into working.
Dell tech support guy logged onto my XPS15 this morning and saw first hand the issues, and they have now agreed to send out a replacement TB16 which should arrive by the end of the week, but to be honest I don't have any faith that the next one is going to be any better than the pile of SH 1 T currently connected to my laptop
I have told Dell technical support that I'll be looking for a refund of the TB16 and my XPS15 if they can't resolve the docking station issues.
My faith in Dell products is rapidly diminishing, and I would strongly advise people to think twice before parting with many $$$ for products that in my view really aren't worth the money, aggregation and frustration.

A:Same issues with the Dell TB16 as with the TB15???

Sorry to hear you are still having trouble.   I assume that the technician walked you through all of the required updates but just in case, please refer to this article.   If you are still using downrev BIOS, chipset, firmware or drivers, this could be the source of the problem with the new TB16.   If you continue to see issues after updating and receiving the replacement dock, please reach out to me via PM with service tag and contact information so that we can get you up and running.

i have some issues with my Dell XPS 13 (9350) and Dell TB16. I connected a 4K Monitor on the MiniDP Port and another 1080P Monitor on the HDMI Connector. I get constant dropout of my 4K Monitor, like every 1-2h min. the screen goes black and after a few moment the video comes back. Updating everything to latest BIOS, TB Firmware, Video Drivers does not working. I tried to disable TB security in BIOS but this doesnt help either.I tested my TB16 with another device, this time it is my company Lenovo P50. Everything works great with this device, no video dropouts, i tested this several ours.
So what is wrong with the Dell XPS13 and Thunderbolt?

We have a Tb16 dock in at the moment for trial. It is very unstable on our Latitude 7370's
We've installed all the latest drives from Dell, updated firmware on both the Dock and the laptops but still face issues
The main problem problem as far as I can see is the ASMedia USB 3.0 Extended Host Controller Driver , when installed the dock will just not work with ethernet or USB. No connection at all. If we remove this driver and allow Microsoft to install it's own version then the USB and Ethernet ports work OK however then another issue occurs, the connection constantly drops out over and over again , internet drops out, USB stops working (with the familiar sound you hear when you disconnect a USB device from a PC) and then reconnects again, this happens over and over again. I use the NIRSOFT tool USBLogView and there was hundreds of connects and disconnects over a few hours
The only way we've managed to get it stable is to either put the device into air plane mode or put the power setting on the WiFi adapter down to 1 which obviously isn't a good work around

This isn't just one one laptop either, this is on all our Latitude 7370's we've tested

So I got the TB16 to use with my Windows 10 Precision 7510. I've had issues with the USB devices dropping out randomly but I seem to have got that under control (for now). I'm having another issue of sorts. Updated the BIOS then went into the BIOS changed restart/shutdown to "thorough" and checked "thunderbolt adapter boot support" and "thunderbolt adapter pre boot modules" as I wanted to boot from a USB DVD drive that was connected to the TB16. But when I tried to boot the laptop got stuck on the Dell logo and wouldn't go into POST. I tried diagnostic boot and got the same result. Couldn't get far enough to press F2 or F12. When I disconnected the TB16 and powered on the laptop it booted up fine. I could then connect the TB16 and it would work fine. But if I tried to restart with the TB16 connected I had the same issue. I eventually unchecked "thunderbolt adapter boot support" and "thunderbolt adapter pre boot modules" just so I could restart without having to disconnect the TB16 (I don't know which of the two options is causing the booting issue though). I can get by without booting from the TB16 but I got it partly for that reason so would to get it working if I can. Any ideas?

So I got the TB16 to use with my Windows 10 Precision 7510. I've had issues with the USB devices dropping out randomly but I seem to have got that under control (for now).
It might be if the devices are intermittent, they would exhibit problems during a Pre Boot Scan.
I wanted to boot from a USB DVD drive that was connected to the TB16. But when I tried to boot the laptop got stuck on the Dell logo and wouldn't go into POST.
You are wanting to boot a UEFI capable DVD, such as the Win 10 Install media, connected to the TB16?  If that is the case, I can test to see if I can do it.  I am wondering if the Thunderbolt is connected to the PCIe bus if any device there will be checked for boot compatibility.  
I suppose you can boot from that USB DVD when connected directly to your system?

I have a Dell Thunderbolt Dock TB16 - 240W docking station for the XPS 15 9560. It comes with a 0.5m USB Type-C Thunderbolt cable. Is there a longer cable, such as a 1m cable available for the TB16?
The TB16 was shipped from Dell with an instruction booklet entitled "Thunderbolt 3 (USB Type-C) Dock Cable Installation Guide." The book has instructions on how to remove the shipped cable and replace it with some cable that is received as a separate shipment. Does anyone know the purpose for those instructions? 
I'd like to suggest that the above questions would be a nice addition to the TB16 FAQ... adding some info on cable length, cable length restrictions, future plans for differing cable lengths, etc., might help users such as myself. I see others out there which have concerns about short cable length so that's why I think the answer to the above would make good TB16 support KB articles or FAQ entries. 
Thank you!

A:Dell Thunderbolt Dock TB16 Maximum Cable Length

The included instruction guide is just in case you need to remove the cable for replacement.
My cable is around .4 meters or 16 inches.  I do not know of other length cables are available.

I'm using a TB16 with a XP13 (9350) and a single 4K monitor (Dell P2715Q). The setup works perfectly at 30Hz but at 60Hz it flickers continually. By flicker I mean the external display switches to black for 2 to 3 seconds several times per minute. The BIOS of the XPS13 and all drivers are current. MST is turned off on the monitor. The setup works fine at 30Hz. I tried enabling airplane mode as others suggested in this forum and it made no difference. I have also tried several DisplayPort (mini and full) cables with no success. 
This is not an issue with the monitor as I can hookup a Surface Pro 4 at 60Hz without any issues. 
One interesting thing is when I hookup the SurfacePro4 it defaults to 60Hz but when I hookup the XPS via the TB16 the default refresh rate is 30Hz and I need to change it to 60Hz using the display adapter settings.
Is anyone successfully using a similar setup without flicker? The TB16 specs list it as capable of supporting 2 4K monitors at 60Hz.

I updated drivers on all devices, including setting the XPS to do nothing when lid is closed. External monitor works fine, until XPS lid is closed, then external screen blanks. However, monitor works fine in airplane mode, which does me no good, as I need an active internet connection for certain software functionality. Also, airplane mode disengages my wireless keyboard and mouse, and I need to turn connection back on and pair devices (wasting more of my time). Is there anyway around this issue, other than returning the TB16 for something that works?

Title in the subject line pretty much says it.I've got a Dell Precision 5510 and a TB16 dock.It is currently running Windows 10 1703 but this issue existed under Windows 10 1607 as well.
Sequence of events/how to replicate:

Connect the Precision 5510 to the TB16 dock (presence of any other combination of peripherals seems to be irrelevant)
Boot into Windows 10 and enable BitLocker using TPM and a PIN
Shutdown and power on or /restart, whilst still connected to the TB16, enter your PIN and boot successfully
Shutdown and disconnect from the TB16 dock then try to boot - BitLocker prompts for the great big recovery key (what a pain)
Entering the recovery key and proceeding to boot is fine, as is shutting down and trying to boot again with the TB16 attached but if you're away from the office (and the TB16) and don't have the recovery key, then you're in a bit of a pickle!
If you've...

Booted with the TB16 attached
Shutdown and disconnected from the TB16
Booted to encounter BitLocker recovery (but luckily had the recovery key with you and entered it)
Continued to use the Precision 5510 away from the TB16 and restarted...then you have no need to encounter BitLocker recovery and re-enter the recovery key again

One you go back to connecting to the TB16 though... you guessed it, you need to re-enter the recovery key again.

Q: TB16

Well I wish I could report that my work productivity has been improved by the TB16 but it hasn't. Blue screens left and right saying a "Critical Process Died."  Ethernet cable and usb ports will go out after about 2 min of being connected to the laptop. Its almost impossible to the get the laptop out of sleep mode when the laptop lid is shut. I haven't had the issues with charging that I did before on the TB15 and WD15 which is a plus. So all in all I have a new TB 16 powered by a 240watt brick that is a brick. I've downgraded my workstation to two 22'' monitors with infinity bezels (nice job dell) but still not a viable option if I cant even keep the laptop from crashing. I pretty much over the Precision 5510 not sure why Dell promoted this as a business laptop with no reliable docking solution. Ready to switch to another laptop.

I'm a new owner of a XPS 13 9365 + TB16 dock. 
My issues are:
1) The TB16 fan whines at a shrieking high frequency.  The tone is identical to this pitch: http://www.szynalski.com/tone-generator/#1593
2) The T16 fan does not shut off when I put the XPS to sleep, but it does when I choose to shut down instead of sleep. 
I should mention that the vents of the TB16 are not blocked and my environment temperature is not warm at all.  I can hear the whine anywhere within 3.5 feet of the dock to the point where it's a major disturbance.  It's not possible for me to place it at that distance away from me due to the short length of the TB3 cable.
I tried changing 'wake on Dell USB-C dock' in BIOS (yes, the latest bios/drivers) but it had no effect on issue #2 above.  I can't think of any sensible reason why the TB16 fan should run endlessly while the XPS is asleep.
Is there anything that can be done about these issues?  My service tag for the TB16 was not recognized by Dell's registration tool. 

A:TB16 fan issues

My fan does not make that much noise but it might be important to know what you are running from the dock.  In fact, I don't notice it until I listen for it.  But I am not running any monitors.
I am not sure right now if my fan turns off when asleep but this may be related to the original noise during use.   You did a firmware upgrade for the dock on your 9365?
I don't know about the service tag but make sure you are reading all digits correctly.  I will check the sleep fan operation on my system.

I just got a TB16 240W doc.   I see several posts on how this works with the XPS 13 9350.  The two main issues appear to be
(1) screen going blank when you close the lid of the XPS
(2) power issues with the laptop and peripherals 
I am seeing (1) but not (2) with my 240W system.  I did encounter issue (2) with the previous Dell DA200 Doc which did not have it's own power, but what I'm seeing now is that aparently the TB16 is supplying and not using the XPS power.    In fact I bought the 240W version rather than the 130W version of the TB16 precisely because I had this problem with the DA200 Dell Doc.  The XPS 13 9350 does not have the power to drive both peripherals and the internal WiFi device so I had to disable the internal WiFi to get my system to work.  
Most people posting issues here don't say which version of the TB16 doc they have, so I would be unable to tell if the TB16 130W would have issue (2).
Because of issue (1) with the HDMI port, I would guess that the HDMI port does not have it's own memory and must use the laptop's memory.  I haven't tried the other monitor ports in the TB16.  The TB16 is supposed to support two 4K monitors I think, so I assume some of the ports must have independent memory....

Hi,Welcome to our community.Thank you posting your message here. We’ll try and assist you. We request you to connect the external monitor to the system without the TBI6 and check if the issue re-occurs.The reason there are two models is because power passes through the TB16 to power the laptop.

I have been previously using a usb-c to Displayport adapter with no issues. Also the power button on the TB16 does power down the XPS 15.

My 9365 uses the Thunderbolt for Power, so the TB 16 plugs into that same port.  Your system seems to use a normal power adapter in it own port.  The manual states the USB c port on that system does Power Sharing.. Are you certain it is supposed to power the system that way?

I have just bought the "new" XPS13 2-in-1 and TB16 thurderbolt dock from Dell Hong Kong official site.

I have to said it was a very very bad experience.

First, since I have received the laptop. The touchpad is often out of control. It will suddenly fly everywhere on the screen, crazy clicking everything and I can hardly control it but to restart. Sometime, it even has NO response.
I have tried a lot of method. Updating BIOS and drivers were not worked.
Once I received this laptop, I went to business trip with it. I have tried all methods to fix it. I read many article online but none of the methods work! This laptop drove me crazy during my trip!!

And most craziest thing is, when I come back from my trip. I try to setup the TB16 dock. It has NO RESPONSE after I plug it according to the instruction. No light, no response, JUST LIKE A BRICK!

I have email the sales to ask for help or advice. She is simply NO REPLY.
I have also asked for technique support from official site. It is just a extremely NOT user friendly. It even cannot search the service code of TB16 dock!

I would say, if you are considering to get a dell, please think it twice.

A:XPS13 2-in-1 and TB16 dock PROBLEM!

As far as the touchpad, it is very sensitive, which you may be able to adjust.  On my system the touchpad is just barely below the lever of the palm rest.  Does yours look any different from that?
If you are typing and happen to brush the touchpad, the cursor can jump to another location.  That is why the setting to delay inputs while typing is there.
I just got the TB16 and finished setting it up, although I have not connected it yet.  There are drivers for download on the 9365 site in the Dock section.  Before you plug it in you need to install the Thunderbolt firmware and controller driver.  Then the drivers for the USB, Audio, Ethernet, etc.
If you have the Thunderbolt Controller software installed, open it to Settings and look at Details.  It should show the different software versions.
As far as lights, there is a bright blue light in the power plug.  There may also be one on the USB C plug which goes into the USB C port on the left next to the combined audio port..

I have the XPS 15 9560 with the i7-7700HQ and the 1080p screen.  The laptop works fine by itself and it works fine with a WD15 dock at my home with 1 montior.  At work I used the TB16 dock with the 240W adapter and I have 3 Dell U2414H monitors connected (DisplayPort, HDMI and Mini DisplayPort).  The Monitor connected via DisplayPort flickers at least a few times every minute.  The Monitor connected via Mini DisplayPort has flickered just a few times and the one connected via HDMI has never once flickered.  I have updated the bios to 1.1.3 and I have updated the Intel and the NVidia drivers.   I apologize in advance if this question has already been answered.

I'm using a TB16 dock with an 5480, and I have 2 problems:
- If I use the TB16 dock Ethernet plug, incoming Ethernet packets are corrupt. Websites don't load correctly, downloaded files are corrupt. However, no errors are displayed in the syslog, and ifconfig reports 0 TX/RX errors on the eth interface. Laptop Ethernet plug works without problems, so now I have to plug the Ethernet cable to my laptop instead of the dock.
- If I plug USB devices to the dock before I turn on the computer, everything works great, but if I plug a device after the dock has been powered up, it randomly looses USB connectivity. Seems like the USB hub switches off inside the dock, as connected devices even lose USB bus power when this happens. This happens even if I plug my Dell U2717 display's USB cable to the dock, or a device which can reenumerate itself without plugging it out and in. Now I use the display's USB, keyboard, mouse, USB HDD etc. plugged in constantly to the dock, this works without problems, and I plug other USB devices during work to the laptop's USB ports to prevent the dock USB hub failing.
I'm using LUbuntu with the latest stable Linux kernel 4.11.3 and latest laptop BIOS version 1.4.3.

Just got my defective TB15 swapped out for a TB16.  So far the USB connection and display connections are rock solid.  Still having a problem with the USB-C port on the TB16, however.  I have an Akitio SK-2520 USB 3.1 Gen 2 dual sata RAID enclosure populated with 2 x 1TB Samsung 850 Pro SSDs.  
Plugged directly into the USB-C port on the 5520 itself I get the following in CrystalDiskMark:

Plugged into the TB16 I get the following:
The enclosure has external power because neither the laptop nor the TB16 can provide enough wattage to power it.  It is a USB-PD certified device, so not sure why I have to use it's external power brick, but that's another discussion entirely. 
At first I thought the fact that I'm driving my LG 34UM88C-P monitor (2440x1440 resolution) was eating into the bandwidth available to the neutered TB3 20Gbps connection, so I disconnected it.  Even with the enclosure being the only device plugged into the TB16 the speeds remain the same.  The USB-C port on the back of the TB16 has a Thunderbolt logo indicating that it's TB3 certified.
Per the Intel Thunderbolt 3 FAQ: "Thunderbolt 3 is a superset solution which includes USB 3.1 (10Gbps), and adds 40Gbps Thunderbolt and DisplayPort 1.2 from a single USB-C port."  Meaning that port should be capable of providing 10Gbps of throughput to be a properly certified TB3 port.

A:Precision 5520 + TB16 = Slow USB-C connection

I think the problem is likely in the limitation of PCIe over TB3. 40 Gbps of TB3 is dynamically shared among DP and PCIe lanes. Up to PCIe3 x4 (32 Gbps) is generally possible (assuming DP not taking more than 8Gbps, otherwise DP has priority), however the 5520/9560 support only PCIe3 x2 (16 Gbps ) - this was found by the eGPU gaming community and later confirmed by Dell. Likely even less than that is available via the "downstream" TB3 connector on the TB16, because the TB16 occupies some of the PCIe bandwidth. The TB16 specs don't list much for its TB3 port, maybe it is restricted at USB-C 3.1 gen 1 5 Gbps?
Regarding USB-PD, cross-compatibility is a tricky issue. The two devices must negotiate a voltage-current pair, and many devices which are not primarily power supplies in practice don't support different voltages. I gather the Akitio wants 15W @ 5V 3A, while the Dell laptop and dock likely only offer 20V, maybe also 5V but at a low power.

I'm having issues getting the TB16 to work with the XPS 15 9550. I successfully installed all the drivers in the proper order as documented prior to plugging in the TB16 for the first time.

I've verified that I indeed do have a Thundrerbolt port - there is a Thunderbolt symbol next to the USB-C port.
When I do plug in the TB16 the power button on it will power the system off/on.
I've used a usb-c to Displayport adapter and a usb-c to usb 3.0 adapter with a flash drive. Both worked successfully so the basic functionality of the usb-c port is working.

When I plug in the TB16 I never got an authentication window pop-up. In the Thunderbolt software it shows no attached devices.

The details setting in the Thunderbolt software looks fine, it appears to have the proper driver and firmware levels.

When I check the Thunderbolt driver it says that 'the hardware device is not connected to the computer'.
I'm at a loss - everything looks good except for the fact that nothing happens when I plugin the TB16. I'm wondering if there's a hardware problem with the Thunderbolt controller itself? I'd appreciate any help that anyone can give me.

A:XPS 15 9550 - Thunderbolt port not working - TB16

You might open the Thunderbolt software and set it to allow all devices.  I reset my system and redid the TB16 and it shows the cable and dock as approved devices.
It was not hard for me.  The thunderbolt controller is on the computer.  You show some correct info for that controller, although since I have a 9365, that specific info may be different, but you do show a different controller generation..

XPS 13 9350 (i7 6560U, WQXGA+). TB16 240W. External monitor Dell P2415Q 4k, connected with full DP.
Notebook connected with TB16 with Thunderbolt 3. All external device (some USB, audio, ethernet, monitor, mouse-keyboard) connected through TB16. Works fine, but not for long.Randomly ALL peripherals connected become inaccessible, except external monitor that is stay working. Fixed only after reboot.
All drivers installed, except USB ASMedia eXtensible Host Controller driver - any attempts to use dell drivers failed, it works only with standard windows driver. BIOS and thunderbolt firmware updated.Turn on airplane mode does not help, as well as changes over Bluetooth power state.

Recently purchased a XPS 15 9560 (fully spec'ed) along with a TB16 Thunderbolt dock. I have 3 x Dell U2414H.
I have been trying to set up the TB16 dock to have three monitors running; 1 monitor per port at the back of the Dock:- (HDMI, Mini Displayport & Displayport).
However whenever I try to connect the full Display port, the unit freezes my notebook.
I have run through the suggested set up a few times (automated and manual); reinstalling all the drivers and firmware updates, but with no success.
Appreciate if anyone on the forum has encountered this issue, or should I be logging a ticket with Dell.
Thanks in advance.

A:XPS 15 9560 & TB16 - Triple Monitors Issues

* Turn the laptop and all three U2414H off* Disconnect all three U2414H from the TB16* Lets call the three U2414H A/B/C
* Connect U2414H A to the TB16 dock DP using a DP to DP cable* Turn the U2414H A on, then the laptop. Does it work?
* Turn the laptop off* Connect U2414H A to the TB16 dock DP using a DP to mDP cable* Turn the U2414H A on, then the laptop. Does it work?
Now do the same testing of both DP to DP cable and DP to mDP cable on U2414H B/C.

I've just purchased an XPS15 9560 and a TB16 (would have preferred the smaller WD15.. but no official support for the 9560)
I'd like to add a right-angle adapter to the TB cable to get it out of the way, but I wanted to make sure whatever I got would still charge the computer and otherwise fully function as a docking station.
Does dell sell one or can anyone recommend one that has worked for you?

First question: Using the ASUS ROG PG279Q with TB16 and 9550 - No 144Hz possible via DP or Mini-DP. Everything fine till 120Hz but when switching to 144Hz the screens flickers like crazy. Unusable!
Tried until now:
- Drivers updated for Nvidia and Intel 
- All Drivers for TB16 installed 
- Tested on Mini-DP as well as DP of TB16
- Monior and same Cable work fine at 144Hz on Lenovo Laptop with integrated Intel Graphics
Any hints please?
Second question: Also, is it possible to force the NVidia Driver a different Refresh Rate when in use? So for example, in Desktop mode when doing office stuff I am fine with 100Hz whereas when I play and the NVidia kicks in I would want that to use 144Hz or even 165Hz
Thanks in advance

I am about to order an XPS 15 9560 and looking at TB16 dock ... in specs it shows XPS 15 as supplied with 130W power adapter but in specs for TB16 the chart shows 240W and says "NOTE: A system requiring more than 180 Watts must have its own power adapter attached"
Does that mean that for the XPS 15 i need to connect the power cord even if I am using the TB16 dock? I thought the TB16 would mean I could just use the single connection.

I have purchased the new XPS 13 2-in-1 laptop.
The Thunderbolt 3 port on the left side of the laptop is not working.
I have also purchased the TB16 dock and it is not recognized at all.
In the Thunderbolt software details, it shows the Controller driver as "Unknown".
I am out of ideas.
I have done the following:
1. Clean install Windows and run all updates.
2. Install all of the latest drivers and Bios updates, in order, according to the official Dell guide for this laptop.
3. Followed guides in this forum and Reddit forums.
4. Had Dell support come in and replace the motherboard.
The TB16 dock is still not detected, nor is any other Thunderbolt or USB-C device connected to the port on the left.
The TB16 dock, however, does charge he laptop and properly shuts it down if I press the power button on the dock.
I have checked the Bios settings, and also tried updates/fixes from Intel. Nothing works. The Thunderbolt firmware update cannot even run because it cannot detect the controller. It still says Controller Driver as unknown.
I have the i7 with 16GB RAM, and 512GB SSD.

A:XPS 13 9365 - Thunderbolt/Power port not working - TB16

So you have loaded the Thunderbolt drivers (firmware and Controller) and it is enabled in the Bios?
There are also Dock Drivers.
I do not have any Thunderbolt devices so I cannot check.

Looking at the documents for the dock it looks like this is capable of this setup but I cannot figure out how to get it working.
The TB16 supports 3 external FHD monitors ...., I would assume I could also have my internal laptop screen running also. Am I wrong?

I just received the TB16 dock, using with a Precision 5520 with Ubuntu and an P2415Q external monitor, and am happy with them, except for one regression.
In the past I've adjusted the brightness of the monitor with a command-line program that talks DDC over I2C and it works great changing brightness between morning, afternoon, and night modes.
I purchased the TB16 for the main purpose of providing a single cable connection to everything. But, when I connect the external monitor to the dock the DDC command signals are blocked (or not relayed). In short, I need a second cable to control the monitor.
This defeats the main purpose of the dock, and it is quite expensive for the other features, I certainly could spend less than $300 on a second power supply and usb hub. :-(
The question is then, is anyone aware of this problem, is it possible to be solved, and will it at some point in the future?

Kind of a multi part question here.
I have a Precision 7510 and a TB16 Dock. I have the quadro m2000 graphics card. When I have my dock connected I connect a display port cable from my dock' s display port out to my dell 4k monitor. The max resolution is either FHD at 60 hrz or 3840x2160 at 30hrz. The 30hrz option is not acceptable for me. I end up trying it with a mini display port to the dock with a display port to the monitor adapter cable that came with the monitor. That gives me the full 3840x2160 resolution.
Two questions here.
1 why am I not getting proper output from the full size display port on my dock and is there something that can be done to correct it as I think I should be able to connect another 4k monitor and was thinking about getting another of the dell ones but don't want to unless I know it will work.
2 I see a lot of info on the different revisions of both display port and hdmi. I think the latest display port revision is 1.4 or something and  hdmi is 2.1. What version is my machine able to support? In looking for help online with question 1 I found info that makes me believe it could be related to what version of display port is supported by my machine. That is why I am looking for that info.
Thank you

I just got TB16 to replace  my TB15 and I'm noticing that my Dell W3415U which is connected to my TB16 HDMI port goes blank for few seconds comes back every few hours. Like the video signal suddenly stopped or something. Not sure what's causing it but it's bothering me since it's happening while in middle of my use. TB16 is connected to my XPS 15 9550 running Windows 10 Pro via Thunderbolt 3 port.
If you know how to resolve this I would appreciate any help.
Thank you.

A:TB16 HDMI connected monitor goes blank for few seconds every few hours

Hi,Welcome to our community. Please make sure that the ports are intact and there is no lose connection. The screen going blank intermittently might be because of the lose ports.

I had my setup working perfectly on Arch Linux before updating my bios. The dock could be plugged and unplogged at will without crashing. After updating to the latest bios (To get the Intel ME vulnerability patch) it doesn't work anymore.
Connected on the dock:
One 1080P screen (HDMI)
Another 1080P screen (Display port)
USB mouse and keyboard
Ethernet cable
3.5mm jack to sound system

Setup that worked
Bios: 1.2.18
Kernel: 4.10.6-1-ARCH

Setup that crashes
Bios: 1.2.25
Kernel: 4.10.6-1-ARCH
Kernel: 4.10.13-1-ARCH

Expected behavior
Connecting the dock when the laptop is powered works.
Connecting the dock when the laptop is turned off and booted works

Actual behavior
Connecting the dock when the laptop is powered crashes the system
Connecting the dock when the laptop is truned off works, but mouse and keyboard don't work.

Anyone has pointers on how I could resolve this issue?
Thank you very much.
