Yep. And the author of scrcpy is also one of the developers of VLC media player - another piece of software that just works.

scrcpy is amazing software something other people might not have realised you could possibly get Dex on some unsupported devices. I got it working on my Galaxy Z Flip 5 using scrcpy --new-display=1920x1080/284

This thing also helps capture images from stupid crap apps that prohibit screenshots. On my rooted phone with a disable-flag-secure module installed, adb screenshots are still black.

Recording a video via scrcpy works on the other hand. Amazing, agreed.
