I've been trying to get my ThinkPad Hybrid USC-C with USB-A dock to work with my Dell P2422H monitors and Dell Latitude 5420 laptop.  When I plug the monitor into the docking station with the DP connector or the upstream cable the monitor says that there is no signal detected.  The monitor works when I plug it directly into my laptop, so it has to be something with the dock.  Can you please let me know how I would get this to work?

Thanks!

Hello JennyVan and welcome to community forums!

Unfortunately, there is a list of compatible devices for the dock and you can check it here: https://smartfind.lenovo.com/accessories/#/products/40AF0135US

However, try installing the dock drivers first and restart the laptop before installing the dock's firmware here:

Hope everything goes well for you.

Jwes_Lenovo,

I haved tried reading through all of the community forums and postings about issues with the ThinkPad docking station and issues with monitor detection. NONE of the trouble-shooting I've tried has worked. I have a Lenovo laptop , ThinkPad docking station, and two Dell monitors. Sometimes the monitors are detected, sometimes they aren't, and the docking station doesn't have enough HDMI plug-ins, so I have to plug one monitor directly into my laptop. Can someone please tell me if there is a human I can talk to on the phone about this issue? For such an expensive product, I would hope for better customer support. Please please please help me!

I notice that there was no actual solution. We are running into the same issue with a set of matching Dell monitors. The compatibility list does not include monitors only lenovo computers that it works with. I cannot get the dell monitors to read the signal from the dock. I am going to return the dock as a fifty dollar generic adapter works perfectly where the 300 dollar plus Lenovo dock does not. My guess is that the Lenovo Universal USB C V2 dock does not send out a proper signal for the monitors. 

We can not guarantee third-party compatibility.  We recommend using the tested compatible devices for the machine.

What generic dock are you using? I'm having the same issue.

I'm sorry, but as a Lenovo representative, I can't recommend a specific third-party docking station. However, I would suggest looking for a dock that is known to be compatible with your specific Dell monitors and laptop. You might find user reviews or tech forums helpful in this regard.

Best regards,

I have the same issue with P2422H Dell Monitor, this is a Monitor standard with none special thing works well with a MacBook Pro M3 and with other PC however the ThinkPad doesn't.

What is the technical reason?
