Does OnePlus 8 have desktop mode?

Requirements

1. Your Android smartphone must be running Android 10.
2. Your Android smartphone needs to support DisplayPort Alt Mode or simply video output over USB-C.

If you have a smartphone with the Qualcomm Snapdragon 835, Qualcomm Snapdragon 845, or Qualcomm Snapdragon 855 and a USB 3.1 Type-C port, then your smartphone should support DisplayPort Alt Mode unless the phone vendor deliberately disabled it. Google disabled it on the Pixel 4, for example. Also some of the vendors did not implement USB-C correctly on their phones such as some models of OnePlus and LG phones does not recognize OTG keyboard/mouse when connected via DisplayPort.

If your phone is not listed below,trythis IOS/Android HDTV cable for connection. However, this cable can only mirror the screen of your mobile phone. Other additional function like Desktop Mode, Touchscreen or Keyboard will NOT work.

As of February 2021, the complete list of smartphones that support video output over USB-C are as follows:
