Feature request / Idea: secondary display projection

[tabnul]

I use headunit revived on a stock popup screen that is connected to my phone or tablet via HDMI (using usb 3.1 switch). I use self mode.
So headunit revived is running effectively onthe Android Desktop session (secondary screen)

I start headunit revived from the secondary screen. But the application responds very inconsistent:

• sometimes the setings/start screen starts on the main screen, self mode also starts on main screen
• sometimes the settings/start screen starts on the secondary screen, android desktop starts on phone screen, or the other way around
• sometimes they both start on the secondary screen, which is what i personally want.
• if it starts on the right screen, sometimes the DPI is incorrect and/or mouse cursor is not aligned with the self mode screen. probably related to:
  • dpi and resolution of secondary screen differs from main screen
  • self mode initially starts windowed on the secondary screen, need to change it to fullscreen, i think this results in the mouse being misaligned with the projection

Behavior occurs on both a Samsung device with modern Dex but also in vanilla desktop mode on a Pixel.

I was wondering, it would be great if there was a setting that would force the Self Mode onto a secondary screen (directly fullscreen)
I understand this is a niche feature, but maybe an easy fix, not sure.

i did figure some things out in the mean time;

• dpi issue and mouse mis-alignment: this only happens on vanilla android desktop and this is the case when the screen DPI does not match the overlay DPI. In fullscreen things get misaligned.
  Formerly i had no choice as android did not publish all available resolutions, since one of latest beta patches it does and now i can align it properly.
  In dex it wasnt an issue to begin with.

• the focus issue, app launching on the wrong display: removing android revived from the active windows in the main screen (so closing it effectively) fixes this issue. This behavior also recently changed. The android desktop experience is heavily developed still.

it would be really nice if the main display would be able to take control of the secondary display (send android auto fullscreen to that display from a revived start menu on main screen) but i expect that permissions and such will get in the way of building this functionality.
