Triple Monitor Display issues: ThinkPad Thunderbolt 3 Dock Gen 2

Hello All,

 

 

I have recently purchased: https://support.lenovo.com/ca/en/solutions/pd500265

 

So far everything except the displays has been working fine. I have 2 Display port monitors and one HDMI monitor hooked up. I made sure that the HDMI was plugged into the right one as per the manual for display port operation.

 

All 3 show up fine in windows settings:

The first time I plugged the dock in only display 4 and 3 worked, 2 never did, and after rebooting now only 4 is working. 

2 is an HDMI monitor and 4+3 are display port. they do not work even when they are the only ones plugged in.

 

Any ideas? I have updated both the drivers and FW

Now, none of my displays are working! They work fine when plugged directly into the computer still so it is not the monitors.

well, I got the two display port connections working again, apparently, the dock cannot run over 100 hz on any monitor without becoming unstable... 

 

My HDMI port still has no output even though the computer sees it, and works fine when plugged into the computer directly. I have tried both ports, the other port isn't even detected.

Another update to the weirdness, if I switch one of the display port monitors to be driven by the HDMI it works, but not the other one. But both work just fine when running directly from the machine.

If I cannot solve this before Monday it's going back to the store.

And we're back...

Move delayed but still coming
