How to change HDMI display resolution and density

HDMI displays that report supported resolutions using EDID are supported. 1920x1080 display resolution is used by default.

Edit device/brcm/rpi4/vendor.prop and change the following line to use some other resolution that your display reports as supported (e.g. 1280x720).

# Display
debug.drm.mode.force=1280x720

Also display density should be changed to adjust to the changed resolution. Edit device/brcm/rpi4/BoardConfig.mk and change the following line.

# Display
TARGET_SCREEN_DENSITY := 160
