Display glasses usually require DisplayPort Alt Mode over USB-C. Some Android flagships support it; many mid-range phones do not.
Smart glasses for Android
Android compatibility depends heavily on the exact phone model. USB-C does not automatically mean the phone can output video.
Check the official support list
RayNeo, XREAL and Rokid maintain device compatibility guidance. Use the exact phone model rather than assuming all Android devices behave the same.
AI glasses
Ray-Ban Meta, Even, Halliday and Solos typically rely on Bluetooth and a companion app instead of direct video output.
Desktop modes can help
Phones with desktop-display modes can be especially useful with wearable displays, but support varies by device and software version.
