Mirror Only
 

Hello,

I am using Dell monitors - U2419H, P2419HC.
My macbook Pro M1 Chip is connected and charged via USB-C to the P2419HC and from this monitor, connected the second one via DisplayPort but the app does not recognize the monitor and I have the message:
No DisplayLink-enabled display detected

I am using the Alpha version 1.8.0

was wondering if there is a better solution for connecting those monitors with only one cable to my mac

The monitors you are using do NOT have DisplayLink technology inside of them, so DisplayLink will not be able to assist you.

The U2419H monitor has a DisplayPort MST hub inside of the monitor. This enables you to connect a second display to the monitor's DisplayPort output in a 'daisy chain' configuration.

Apple Mac systems do NOT support DisplayPort MST daisy chain configurations. This is why both displays are showing an identical 'mirror' image.

In other words, what you are attempting will not work on a Mac.
