Product: Elitebook 840 G5
Operating System: Microsoft Windows 10 (32-bit)

My Elitebook 840 G5 when hooked up through thunderbolt to my USB-C G4 dock will not detect my external monitors.  All Bios and drivers have been updated.  The G4 dock and monitors work perfectly with my other Lenovo computer.  Also, I have tested the Elitebook at my work using a VAVA dock and HP monitors and it works fine.  Can someone please tell me what is going on and why these two HP products do not work together even though they are compatible. 

 

HELP!!!!
