Google built a barebones launcher for external displays so developers can test what their apps might look like on large displays, but they didn’t even bother adding display out support on the Pixel 4. Sadly, this means that Android 10’s hidden desktop mode is unusable on the latest Pixel smartphone, but if you have the Essential Phone, OnePlus 7/7 Pro, OnePlus 7T/7T Pro, or any other phone with video output over USB-C, then there’s a way to make it more useful. Your Android smartphone needs to support DisplayPort Alt Mode. 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.
