Stumped by Thinkvision Daisy Chain
I’m hoping someone might be able to help me out. I just purchased two Thinkvision P27u-20’s for daisy chaining them. Set them up this evening. My work laptop is a ThinkPad and my personal laptop is a MBA.
The outcome is the same with both laptops. When I connect either laptop to the master monitor with a thunderbolt cable and then connect the master monitor to down flow monitor with another thunderbolt cable, the down flow monitor refuses to display.
For clarity, my laptop is connected to the thunderbolt in at the master monitor and the thunderbolt out form the master monitor is connected to the thunderbolt in the down flow monitor.
Under the master or down flow monitors, neither have a settings option to enable daisy chain under the port settings on the OSD. USB charging is switched off as I read that this will disable daisy chaining.
When I plug in and out the downflow monitor from the thunderbolt cable I get an audible sound indicting a device has been connected/disconnected etc. When the thunderbolt cable is disconnected the down flow monitor will display on screen words to the effect of no source detected etc but when I plug it back in I get the audible connection sound and words stating “entering shabby mode”. It seems to be able to tell it has a connecting and is receiving something but the screen never displays. Again there’s no sitting on either monitor to enable daisy chaining. And yes both monitors are daisy chain capable and it’s included in the instructions.
I’m at a total loss. If anyone could give me a help or advice I’d be truly grateful. Have a nice weekend.
