Precision 3530 with TB16 Dock. Monitors not working.

I have a precision 3530 (Intel UHD 630 and nVidia Quadro P600) that is fully updated and I even installed the latest nVidia DCH driver. I have two 1080X1920 monitors connected to my TB16 dock via the display port and mini display port connections. 

Only one of these displays will work at a time. If I unplug the one currently working, the other is detected by Windows. If I plug the one I just unplugged back in, it remains undetected. Rebooting the laptop, the TB16, or just unplugging the thunderbolt cable and plugging it back in will activate one of the two external monitors at random.

The Intel graphics application shows only one external monitor in the topology.

nVidia control panel's PhysX tab shows two ports on the UHD 630 graphics, one with the laptop display and the other with one of the external monitors. It also shows 6 empty ports on the Quadro P600.

All the documentation for the TB16 and UHD 630 and Precision 3530 say I should be able to run both external monitors and the native display without issue via the display port connections on the TB16.

I thought it might be the TB16 FW

So I did the firmware update tool v1.0.2. It failed to update the MST2 portion and it shows a current version of 0.0.0f7. I tried the v1.0.0 of the tool and it also failed. Many, many times, I unplugged everything from the TB16 and it from the laptop then from power and tried again with reboots and driver reinstalls, etc. Nothing corrected the issue.

 

Any ideas?

    Try going into BIOS and disabling "Switchable Graphics". I think this will place the laptop in a mode to use just the NVIDIA driver.

    I am experiencing exactly the same issue on my Precision 5530 with the TB16 doc. I have 2 monitors connected to the dock:
    Dell P2217H Monitor - DisplayPort Cable - TB16 Dock
    Dell P2217H Monitor - DisplayPort Cable - DisplayPort to MiniDisplayPort Adapter - TB16 Dock.

    I've updated all laptop drivers to the latest version. Attempted update of TB16 firmware to 1.0.2 and got same  MST2 failure (current version of 0.0.0f7). Attempted update of TB16 firmware to 1.0.0, which failed

     

    I've looked in my system BIOS and don't see "Switchable Graphics", or anything similar.

    @CapinWinky2, have you had any success since your original post?

    Any outside advice also welcome.

    Did you update your laptop's bios?

    You should go to the support page for your laptop and individually download the display driver, bios, and the TB16 dock firmware. Then install them without using any updater program.

    BTW - did you go to the NVidia site and download their most up-to-date driver? You could download GEForce from the site, and use that program to download and install the driver for the graphics card.

    Unfortunately, no. I had to get a different TB16, which worked out of the box as far as dual external monitor support goes. I'm currently typing on my laptop with all 3 screens working. The new struggle is that the "ASMedia USB3.0 eXtensible Host Controller" device stops working with code 38 if I ever unplug and re-plug the dock (I can only plug in once per boot of the laptop, which is crazy). This causes all USB ports on the dock to stop functioning. I've got to say, I'm not impressed.

    Oh, so it was a hardware problem preventing the use of multiple displays...

    I have a 7730 with TB18DC dock, and I also have issues with USB device enumeration when plugging in and unplugging devices from the dock.

    Make sure you have the newest host controller driver. I have gone through 5 different versions of this driver as it constantly causes blue screens if you are on the older version. Also make sure you have the new firmware on the dock. I have computers that have the no multi monitor support not docks. The controller on the laptop seems to be the cause in my case not the dock since I can take a "broken" dock with the same symptoms as you and connect to another laptop and it works fine and reports an updated mst2 version. Thunderbolt has been a complete failure for my 100% dell shop. One issue after another. No QA testing before releasing products. Its been a nightmare with no end in sight.

    Thunderbolt has security settings in bios that count.
