Sharing : Solved M1 limited resolution selection

[tktan]

Hi, just to share how I resolve limited resolution selection for M1 MBA

Dock : Dell D3100 (bought USB type B 3.0 to type C)
Monitor Philip 32" 2k display (model forget)

Issue : after install display link manager 1.2, the monitor only limit the max resolution to 2048x1152 which is not usable

Fix : install RDM (https://avi.alkalay.net/software/RDM/) take ur own risk

RDM allow me to select 2560x1440

Just to share, just incase u r nervous after getting your brand new M1 but monitor resolution disappoint you
