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](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 `: [https://www.balena.io/docs/reference/balena-cli/#logs](https://www.balena.io/docs/reference/balena-cli/#logs) ---

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