Problem controlling monitors independently using DP1.2 daisy chaining

Thank you for the information.

The DisplayLink chip connected to your computer at the time you took the log is a DL3900.
That chip does not DisplayPort itself but use an external transmitter.

I was wrong on when MST was introduced, but our chip still won't send an MST as we support DisplayPort 1.1 max. I doubt the DP transmitter does MST.
"Dual Mode" in the guide should mean you can use a passive adapter to get HDMI. I think the note in the right column refers to the maximum resolution available on the dock. You can use two outputs simultaneously (DP+another), but the maximum resolution on the DP output will drop because of the maximum pixel clock the chip can manage

DisplayLink does not design or manufacture end products, we are a semiconductor company.
I recommend you contact Humanscale for clarification on what they designed their product to do.

Kind regards,
Alban

Thank you very much Alban for the information. Knowing the chipset info for the Humanscale definitely gives me more information and seems to suggest that based on the 3900 specs it will not support DP 1.2. I will continue to follow up with Humanscale to get confirmation.

Thanks again for the quick response.
