I'm trying to get a 5" LCD working with my raspberry pi 3 and Android Things Developer Preview 4.1.
I've added this to my config.txt:
max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
All I get is a white screen with some artifacts:
It's not a cable issue, I can use the screen with my Windows PC just fine.
I've found some maybe relevant lines in logcat:
01-01 00:00:19.529 412-412/? I/SystemServiceManager: Starting com.android.server.display.DisplayManagerService

I've bought the screen from an ebay seller. It came with a dvd, and had a sample config.txt file, it suggests the same settings.
What am I doing wrong?
