I know the Fold 3 has DEX. But has someone tried using a USB-C to USB-C cable to attach to a monitor? I have a touchscreen monitor and I use said cable to connect my Note 9 to enable the touchscreen function with DEX. However when I plug my Z Fold 3, it doesn't work.

There is definitely something up with the Dex on the z fold 3, I use to plug my S20 ultra and s21 ultra into laptop docks to test them and zfold doesn't detect the monitors at all, if I plug direct to screen by usb c or usb c to hdmi it works fine , hopefully this will get fixed

    It's probably the cable - I've tried with usb c to usb c and it works in my case.
