scrcpy v3.3.3 -- Does virtual display launch DeX, or is it something else?

Hi, I have a use case where I want to use multiple virtual displays without going into official DeX mode. (Android 15, One UI 7.0)

I am able to launch multiple displays using "scrcpy --new-display" in a new terminal instance for each. But here's my question: is this recognized as DeX mode by the phone and thus the apps? When I check the quick settings panel by swiping down from the top of the screen, the DeX icon is not highlighted/on, but the new displays look very similar to the official DeX mode layout.

I have turned off the setting "Auto start when HDMI is connected".

Another question, if I want to prioritize speed, should I change the dpi of the new displays?

This is an excellent program. Thank you!

No source file or test is named. Start by tracing the behavior of `scrcpy --new-display` on Android 15 and checking how the resulting displays are identified; done means documenting whether they count as DeX and whether changing DPI affects speed.
