Android Things 0.5.0-devpreview HDMI output isn't available on Raspberry Pi 3

问题

I am using a Samsung monitor and it displays this message

"Mode Not Supported. Resolution not supported.  Change the resolution of the external device."  

I had tried to use different monitor but still can not get the right format output signal.

Display via HDMI is good on 0.4.1-devpreview

Try to check Balaji BABU T.R.'s solution from comments to Wayne Piekarski announce on Google's IoT Developers Community:

Open config.txt in Notepad ++ paste below things

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
framebuffer_width=1280
framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=1

HDMI works fine for me after the above settings
