Hoping someone might have a clue here.  I bought one of these https://www.amazon.com/dp/B00EDT0072 and connected it to the G2 thunderbolt dock for my HP Zbook for work to use my LG 3440x1440 ultrawide as a second monitor.  I had previously been using a 10 foot HDMI cable with no issue directly to the laptop.  The adapter with the same HDMI cable caused constant horizontal "flickering" randomly all the time.  From what I can tell it's possibly a compatibility issue with the dock.  Anyone know of an adapter or cable that will actually work with one of these docks?  I'm trying to get rid of the direct connection to the laptop for cable management reasons and also the 10 foot HDMI is slightly too short in that case for use with my new monitor arms when pulling them out for simming activities.  I debated picking up a displayport KVM switch that I found, but worried it might have the same issue somehow.

    these might work better, as they are Nvidia approved

    Thanks, I see a lot of those mentioning firmware updates.  Maybe that was the issue with the one I got.  When plugged into the dock there was no new hardware notification or anything.  Once I plugged the HDMI cable into the other end I got a display with the random flickering but Windows already knew what the monitor was for instance.  I think I might just deal with the HDMI cable setup I already have that is working.  If I let the cable run diagonally under my desk for now it will clear the monitor arm with enough slack.  Found out my work will provide us with monitors/mouse/keyboard to take home to use with the laptops so once I clean up some other stuff in my office I'm just going to add in a desk for that setup as well.  Will make things look a lot cleaner as well.

    Also, the laptop has a Quadro T1000 in it, but the dock is connected via thunderbolt, so maybe that's the issue as well.  I don't really know anything about thunderbolt.
