hi dears,

how is it possible to mirror qt app?

i don't know which backend(x, xwayland, wayland, fbdev, drm, ...) support this feature and what build system (YOCTO and Buildroot) and which version does support this.

I tested bsp community yocto 2.4 with fbdev+eglfs , separate screen works fine but dual lvds not, and also tested in buildroot with etnaviv.later support screen mirroring  but needs two screen should have same resolutions? and it is impossible to have different resolution.

so which build system and what backend currently support screen mirroring with different resolution of displays with qt?

thanks

Hello

Do you support screen mirroring with different  LVDS and HDMI resolutions( for example LVDS 1368x768 and HDMI 1280x720) ?
