maybe i'm an idiot, but i didn't realize all the use type-c male to male cable differences - in my defense, asus did not catch this (despite having video of me trying to use the external display with the mac and pc) and all 4 of these cables bear no markings whatsoever, ie.

story probably helped, but quite impressed with amazon as i noted my mom got me this external display for a christmas present and that i fully expected to use it on a 4 month trip. expected some painful logistics of me paying to ship it to the states then trying to recover it on a 3 day temporary jaunt back in atlanta. instead they shipped me out a new one 1/15, delivered 1/18, and said i could send the old back once in the states (2/22). new one actually is missing the power adapter (have plenty) - but the real key is that cable... works on both monitors, both laptops... and i'm a bit the wiser.
working from my airbnb and coffee shops for now. there is a wework i can use work credits against during the day, although i haven't tried it yet (and i'm working US hours so my primary normal work time is the night) - airport security is going to be extra fun to go through now.
as an aside, somewhat forced into using a mac for work.
the screen seems nice, and i like having a linux/bsd/terminal as core as it is something i use frequently. this completes my list of things i think are good or that i like on the mac. i have a long list of gripes as to why i think it is otherwise inferior to annoyingly bad. definitely did not convert me to someone who would spend their own money on one.
