Display resolution setup on imx8qm with AAOS 15

Hi Team,

We are using AAOS 15.0.0_2.1.0 on i.MX8QM MEK. After flashing the board, the physical displays resolution is always set to 1024x600, while we want the display to run at 1920x1080.

And we have multi display setup which has android main default display and passenger display.

We verified that 1920x1080 is available in the supported display modes, but the active display mode after boot remains 1024x600. We also tried setting the preferred display mode to 1920x1080 from Android, but after reboot the display still comes up in 1024x600.

Could you please advise:

What determines the default physical display resolution during boot?
How can we force the physical display resolution to 1920x1080@60Hz after boot?
Is there any configuration required for ro.boot.displaymode, Display HAL, HWC3, or DRM to make 1920x1080 the default active mode?

Any guidance would be appreciated.

Hello,

Please refer to the Android Automotive documentation we have available here:
https://www.nxp.com/docs/en/user-guide/UG10176.pdf

Especifically have a look to the chapter 8.3.4 Configuring the primary display resolution of the document above.

Best regards/Saludos,
Aldo.
