Due to version limitations, Switch 2 may not be able to connect directly to portable monitors via a USB-C cable. To address this issue, we have updated the firmware for certain portable monitors, enabling them to work properly with a direct USB-C connection. If Switch 2 receives future system updates, we will also update the software accordingly.
