Hi,

Did you set any contents to display on balenaDash? You can choose any URL to be displayed on the screen. The easiest way to change the URL is by adding a variable into the device variables (LAUNCH_URL) inside balenaCloud. More details can be found here https://github.com/balenalabs/balena-dash#controlling-content

Just be aware that balenaDash requires that you allocate more memory to the GPU. This is achieved by adding (or editing the existing) the Device configuration variable RESIN_HOST_CONFIG_gpu_mem, for this project we recommend setting it to 128.

Hi,
Did you check the logs on the device? They may have pointers to the root cause of the problem.
I would start with application logs that you can can find in the web dashboard or invoking the CLI command balena logs <deviceUUID>:

What is the output of vcgencmd get_mem gpu? How are you exactly setting RESIN_HOST_CONFIG_gpu_mem ?
