Low Android Auto Resolution

[hudiy]

Hello,
We're not entirely sure, but from one of the screenshots it looks like you opened the configuration file from the installation folder instead of the one used by the installed instance of Hudiy.

In the documentation available at https://github.com/wiboma/hudiy/blob/ma ... uration.md we provided the path to the configuration file actually loaded by Hudiy. Could you please try applying the same modification to the configuration file located in your home directory (e.g. /home/pault/.hudiy/share/config/main_configuration.json) and check if it improves the Android Auto interface appearance? Thanks!

Please note that directories starting with a dot are hidden by default in the file manager. The easiest way to edit the file is by using the terminal, for example with the nano editor (nano /home/pault/.hudiy/share/config/main_configuration.json), or by enabling the visibility of hidden files in the Raspberry Pi file manager (e.g. by using the keyboard shortcut CTRL+H).

This was the problem thank you!

For 1600x600:

Code: Select all

"resolution" : "1080p",
"widthMargin" : 320,
"heightMargin" : 480,

Your display resolution is 1600×600.
Since 720p (1280×720) does not fit horizontally (1280 < 1600), 1080p (1920×1080) must be selected.

widthMargin: 1920 - 1600 = 320
heightMargin: 1080 - 600 = 480

Just for the record — in Hudiy, you're free to set any size and position for the Android Auto or Apple CarPlay projection. It doesn’t have to be fullscreen.
You can use the remaining screen space, for example, to display your own custom overlay with OBD-II data or any other useful information.

This was exactly my issue as well. I was confused and started experimenting with different values in main_config.json. I'm sure I would have figured it out eventually, but thank you for the explanation!

I have the same issues with my 800x480 screen. When I'm using 480p it works normally but if I want to go for 720p in AA the screen gets awful quality. No matter if I change the margins or dpi settings. I don't know what to do to properly set this options.

In OpenAuto Pro 720p with 220 DPI looks very crisp and nice to eye

Also - is there any slider or option for brightness control?

If you want to set a 720p resolution for a 480p display in Android Auto, you can try the following settings:

widthMargin = 480 (1280 - 800)
heightMargin = 240 (720 - 480)
resolution: 720p

but we are not sure whether the KMS driver will be able to handle such overscaling and if it will actually improve image quality.
