Nice rig 😉
You need to have Displayport all the way for 144hz to work from your PC. I can't even get the option to go above 120Hz when using HDMI myself but it works great with displayport. The phone will ofc output 120Hz regardless of which cable you use.

Well this answers my question about whether the dock supports 120hz. Thanks y'all

recently i bought two display port cable want to try both using display port for support 144hz display in PC mode and 120hz in phone mode for monitor. it work for my PC display in 144hz but cannot work with my phone 120 hz display in monitor. it totaly black and no signal in monitor. asus dock got problem when using rog ohone 2 with displah port output in monitor?
and then i try previous problem using back hdmi cable for output and setting pc to 144hz again. it working for both pc 144hz and mobile 120hz. maybe asus get my issue and fix it in some firmware update. but i wasted my money to buy extra display cable......
did you really using dock output with display port? it work?
