So reading around it seems Displaylink software does not support 1440p unless the display is native 1440p. 4K monitors seem to support 4K, 1080p, 900p, 720p.

Since my Targus 180 takes care of power, usb devices, ethernet, the Asus 1440p monitor, etc. My M1 still had a port free so I used the xtra M1 USB4/Thunderbolt port and a usb-c to HDMI adapter and plugged my LG 4K monitor directly and set to 1440p. Works for now until displaylink properly supports1440p on 4K monitors.

* Note USB-C to display port adapter works too. I have two macs a my desk. Macbook Pro 15 2017 from work and M1 Macbook Air. So no need to unplug display cables by using Display port with Pro 15 and HDMI with the M1 Air..
