Latest displaylink drivers break lenovo dock 7.2 M1

I also got my dock back.

Lenovo did a 24hr test and did not face the problem :-(

When I connected the dock it was updating the firmware and except of 1 disconnection during 10 hours I did not face the problem anymore.

While it was at Lenovo I installed a different version of the Intel USB3 drivers for solving another another problem.

Later I installed DisplayLink version 7.3 and this also runs fine so far. (driver in device manager seems to be still 7.2)

So my conclusion so far:

Lenovo did something special with the dock
there is only 1 working version out of 5 USB3 drivers
maybe related to any Nvidia driver
operating temperature (before sending back I used it in ~30°C)

Krisha, can I ask what OS you are using? Sounds like windows 7 if you are changing USB3 drivers. For windows 8 there is only the Microsoft provided driver I think.

I just updated to the NVidia 320.49 released on Jul 1. still no change, same problem.

Yes, I'm using Win7 x64 Pro SP1. Currently using Intel USB 3.0 eXtensible Host Controller 1.0.7.248 (which I got from Asus support to solve another problem). I'm using a Geforce GT 650M, driver version 9.18.13.2049 (320.49). Latest DisplayLink drivers showing 7.2.46733.0.

But... during writing this my screens were flickering again 10 times

Only difference is that notebook was in suspend before and room temperature now is ~30°C again. I don't know what's going on

It might be also that just the Lenovo integrated hub is a bad product and it's not really related to displaylink.

edit: I have two LG L226WTQ connected to it.

dhodgin, are you using the same external screen on desktop PC and on notebook?

In the meanwhile I did some experiments with cooling spray :-/ unsure if it helps.

I also did some searches on this forum. Seems a lot of people have unsolved problems with flashing/flickering. Can it be that this is related to any LCD controller inside the external monitors?

update:

my issue is fixed with a new docking station, so probably was a hw fault.
