Issue:

After flashing I.MX 8 board with prebuilt image screen visibility is partial [Cropped screen].

Please find the attached image for reference

Hardwares used :

i.MX 8QuadXPlus and 8QuadMax MEK Board.

Prebuilt image used:

Android 11.0.0_2.0.0 (Linux 5.10.9 kernel) from  Android OS for i.MX Applications Processors

Displays used:

1. TV with resolution 1280x720[ Panasonic TV ]

    2. HDMI 10” display with ,1280×800 high resolution [10''Display]

After changing resolution in bootargs to  androidboot.displaymode=720p30 . TV screen could fit screen but 10” display became blank[ only back light of power is seen].

Please find the logs attached for 10” display.

We would like to bring up screen on 10” display in full screen[ Without cropping]. Please guide us on how to achieve it.

Thanks for the update

We could launch projection on 1280* 800 , 30fps   by updating display mode from bootargs.

##setenv append_bootargs androidboot.displaymode=1200x8000p30

The prebuilt image can't support 1280x800.You need download the source code and add timing information in drivers/gpu/drm/imx/hdp/imx-hdp.c
