PI4 just shows the half of a 1080p hdmi display

I installed Balena Dash on a PI4. The Logo during startup shows up fullscreen.
Displaying Sites in Kiosk Mode via 8080 Port only fill the left half of the screen.
I set
HDMI Output group = 1
HDMI Output format = 16

I don’t know how to fix this. Any suggestions?


Hi there,
could you please clarify what kind of screen are you using ? In addition, could you open the device terminal and share your configurations by copying the output of this command cat /mnt/boot/config.txtplease ? These settings could help us better understand the problem. The most common cause of this type of problem is usually the GPU memory Advanced boot settings - Balena Documentation. You can try to change this value from the configuration variables page Configuration variables - Balena Documentation.

I solved it with Window_Size = 1920,1080
BALENA_HOST_CONFIG_disable_overscan = 1

Now everything is perfect. Took me a while to figure it out.
Thank you for your support.

Awesome! Best of luck using balena.
