does DELL-WD19TB support 2x 2560x1600
 

Hi,

got a macbook pro (running catalina 10.15.7) , connected to DELL-WD19TB

and
2 monitors (DELL U3014) supporting resolution up to: 2560 x1600
connected to the WD19TB

currently I cannot get both monitors to run the max resolution when extending.
it does support both monitors running in mirror mode in resolution 2560 x 1600

But I cant get it to work when using extend.. (can't even select this, as while both monitors are on, and are mirroring, the arangement tab is only showing the laptop display and 1 monitor.)

is it possible to get the max resolution to work on both displays while extending the displays instead of mirroring.

Also, when I use the DisplayLinkManager,
it says:
Connection Status: no monitor detected, while both monitors are on.. and currently running in mirror mode.

The WD19TB doest not require DisplayLink drivers. See this KB from Dell: https://www.dell.com/support/kbdoc/e...le-usb-c-hosts

You have to run one monitor through the thunderbolt port and another through the USB-C, DisplayPort or HDMI ports to get extended mode to work. Any other way (currently) does not support extended mode.
