Android Auto Projection Size

Post by russnash37 »

Hello!

I just purchased Hudiy yesterday to look into. I've been running OpenAuto Pro on a Pi 4B in my truck for quite some time now, but have been looking for a replacement since support for it disappeared and it is proving unreliable connection wise.

One question I have: How can I get the Android Auto projection to take over the whole screen when visible? I can only seem to get it in the top left corner (see attached photo).

I have tried editing the androidAuto section in the main configuration file: I've tried setting the res to 720p and hard coding the width and height settings to 1024x600 but nothing seems to make any difference.

I am using a 7" 1024x600 display connected via HDMI.

Thanks in advance!

Russ.

EDIT: I've resolved the issue! The Raspberry Pi desktop was set to 1920x1080, setting this to 1280x720 (the nearest res to the native 1024x600 of my screen) then allowed me to set the android auto res to 720p and the width and height to 1280 and 720 respectively. I also setup the config.txt to reflect my monitors settings.

Could you get with me to show me how you did it? That is my one last issue that I need to figure out!
