Is this possible?

On the Raspberry Pi 4 (RASP 4), there are two HDMI outputs. I've successfully projected the monitor on one HDMI output with a resolution of 1920x1080px. Now, I need to project a data projector on the other HDMI output with a resolution of 1024x768px. Is this possible?

With WTware it is possible to make another display on projector. Duplication is not implemented.

As far as I know with native Raspberry OS you can make another display OR duplicate image from main screen.
