Connecting portable monitor to Samsung Fold3 usb-c?

[MarcoL9]

I am trying to share my phone screen to my portable monitor using a usb-c to usb-c cable but having no luck. My phone connects to the external display but does not mirror my screen over to the monitor. I was told it should virtually be plug and play, but all I'm getting is a blank screen. Does anybody have any ideas if this is possible on the Fold3? If so any ideas on where I might be going wrong? Thanks

Thanks for your reply Obsydian. Forgive the further question, but did your portable monitor have a usb3 port? Mine only has usbc port.

I use a Samsung M70A monitor, it is USB C no Samsung or other versions worked, after triallingany others I went with two of these.

Ok long story in problem solving, the port is only USB-C, but I found none of the Samsung mobile, tablet USB-C worked with the monitor at all.

So I tried USB-C IF type cables, then Thunderbolt 3 and 4 from Spigen, then I swapped to Cable Matters, link below, excellent only minor issues which again is Samsung hardware.
