Problem between Zlink (v: 3.5.40) and widescreen

I have an Android 9 navigation system with a 1280x480 widescreen, and when launching the Android Auto application through Zlink (v: 3.5.40) it is not seen in full screen, only in 4: 3 format. I have enabled AA developer mode for 1080p compatibility, but the problem persists. Please, do you have any idea which one can see the problem?

The best regards.
