Help Android Auto on Xiaomi - Low resolution image casting

[Toneek]

Hi,

i would ask you an help about a problem related to Android Auto.

Assumptions:
Phone: Xiaomi RedMi Note 9S
MIUI Version: 13.0.1
Android Version: 12 SKQ1.211019.001
Android Auto Version: 8.0.6.623354-release
Car Head Unit: Sync 3.4 on Ford Puma St-Line X

One week ago i purchased my new car. Everything was perfect, but when i tried to connect my Xiaomi to the Head Unit through Android Auto, i realized that the screen casting had an awful image quality: Android Auto seems in low resolution, and sometimes appear some colour artifacts (photos attached).

So, i tried to understand if the problem was my Car Head Unit, or my Xiaomi. I connected various phone to the Head Unit, and in those cases the connection and the display quality were perfect.
Aswell, i tried to connect my phone to different cars, and to the Android Auto Desktop Emulator, and i kept having always the same horrible quality image.

So, from this i got that the problem was my Xiaomi.
I tried everything: with different USB 3.0 Type C cables, i tried entering developer options and change the resolution, i tried the Debug USB mode, i tried deleting and re-installing Android Auto App, and i tried aswell to download a newer beta-version of AA... nothing worked.

But i discovered something: i tried to connect two other Xiaomis... two Xiaomi RedMi Note 10. I imagined that, being the same phone, they would have had the same results. But...

Xiaomi RedMi Note 10 with MIUI 13.0.3 and Android 12 SP1A = no problems, perfect screen casting
Xiaomi RedMi Note 10 with MIUI 13.06 and Android 12 SKQ1 = low resolution, like my Xiaomi RedMi Note 9s
Alle three phones had both the same Android Auto version (8.0.6.623354-release).

So.. it's possible that my Android Auto problem comes from the Android 12 SKQ version?
Someone else had my same problem? There is a way to fix this, or, maybe, to change the Android version from 12SKQ to 12SP1A?

You could try asking in the revised Xiaomi Community App, or or possibly a better bet is to send "feedback" in Services and Feedback at the bottom of Settings. I usually get a human response there within s couple of days iirc.

I did submit an Ask for you in the Community (forum) App with one sentence, but it said there were no related questions, or something similar.

I haven't used the community app, it was very confusing in the past. I was recommended to try it again.

I'm in the UK and my daily is a Poco F2 which has Android 12 SKQ1, but I can't help as I have no access to an AA vehicle.
(I also have a Mi 10 Lite at home)

[SOLVED]
@everyone:

I found a way to "get around" the problem. Using the "official" AAWireless dongle ( https://www.aawireless.io/ ), so not using the cabled USB connection, i had no more resolution problems.

I know that buying something else isn't a real solution, but at least this is a way to use AA in a good quality.

Actually there are a lot of cheaper dongles than this on Amazon, but i didn't try them, so don't know if they will resolve aswell the problem.

Hope this will help anyone that was in my situation.
