No signal, nothing. Might I have an incompatible cable or do I have to buy a docking station?? I hope not!
what is the easiest way to connect more than one external monitor to my P73?
New machine P73 with Quadro rtx 4000 (and integrated intel graphics).
2) Is the adapter thunderbolt or USB 3 type C? If its thunderbolt, check the thunderbolt device viewer. If its not there and it should be, it isnt working.
3) Check the windows screen mirroring options.
4) Check device manager when you have it all connected. There may be a driver issue, or something else.
The monitors otherwise work fine. I can successfully connect using an hdmi cable. No problem.
The ports are Thunderbolt™ 3. Scroll down the page #10 https://www.lenovo.com/us/en/laptops/th ... 2WS2WPWP73
The only Thunderbolt reference in my device manager is under Software Components and System Devices. Related, there is also an NVIDIA USB Type-C Port Policy Controller and NVIDIA USB 3.1 extensible host controller under the Universal Serial Bus Controller category.

Actually, I just saw this on another thread on the Lenovo Forums:
This was the guy's resolution:
Open lid of my T580 and login to Windows (fingerprint)
Connect Thunderbolt cable
Function F7 and go into Extend mode
Turn off each of my monitors and then turn them back on
They each come on with the extended screen
Close the lid on my 580
I'll try to connect it to a different monitor ad have a friend use my cables to check they aren't the problem.
Lenovo tech support won't discuss the issue unless I pay the fee for software support. I'm very disappointed with them to say the least.
