ASUS is a popular computer brand. im just wondering does the rog phone has a functionality or an app that can mirror my phone to my PC using usb/data cable?
No, but there might be a bunch of third-party applications that will let you do that.
If you have as Asus pc then you can install Link to myAsus on the mobile and MyAsus on pc and wirelessly mirror the mobile to pc.
i have a desktop but it is not asus. will it not work?
It's a link about Asus' Link to myAsus.
I really don't have any windows pc around which aren't Asus' so I really can't tell you but since it uses Some if the Asus' custom drivers so it is probably not going to work.
i was wondering if just wired and not wireless. Thinking asus is a brand which specializes on PC hardware manufacturing. i was hoping that there is some kind of APP that can do this.
