how i change the icon size on hmi screen. It's bigger than i expect.

When I connect HDMI and the HMI display, the icons are displayed very large, can I make them smaller again?

I don't have it working myself yet.
But if there are normal Android settings, you could try and change the minimum width (dpi) in the developer settings.

You can also try and force the density in the source.

# Display
TARGET_SCREEN_DENSITY := 160
