Everything is fine and i can see the Tohora link to launch the link on Dash

However, the HDMI is not work, i can’t see anyhitng on my screen. The boot log is appear while the board boots, but after that the screen goes dark

Please help


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.


I have set RESIN_HOST_CONFIG_gpu_mem to 512 and the URL to display i have put it on Tohora but the screen still dark :frowning:

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>:

Here is my log. I am not familiar with balena then i cannot understand it.

Could you please check it for me?


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