Hi, I use Thinkpad P51 workstation. I think when I put the computer on this dock the screen flickers few times a minute. I mean it will go blank (dark black) and would come back on in few seconds.
Using the computer without the dock doesn't cause this as much.
Wondering if anybody else had a similar issue and what was your solution to this.
Thank you very much.

Check screen configuration

not sure what should be the screen configuaration, but I will google that. Thank you for your comment.

Like the other suggestion, I have a feeling this might be related to how the laptop will autodetect new screens when plugged in. A bad dock connection might have the laptop constantly disconnecting and retrying, hence the screen flashes. Just my two cents

How many watts of your charger and what is your detail specs for P51? I have P51 FHD with charger 170W and no issue.

But T14 gen 2 with docks 40AJ with external monitor has sometime the same. I mean few times per day.
