- M1 Macbook Air 16/1TB
- Targus 180USZ

-Displaylink 1.2
-Mac OS 11.1

Two monitors an LG 32UK50T-W (4K native) and Asus 32 Native (1440p native).

No issues with the Asus.

The LG will not do 1440p while hooked up to the Targus.
Naturally 1440p is my preferred resolution.

I tried both Display port 1.4 and HDMI 2.1 cables again these all work fine directly connected. Also tried hooking up only one monitor.

4K is great but its to damn small. I can choose Native, 4K, 1080p, 900p, 720. Holding down the option key does not change the resolution choices.
