Can you provide me with a more detailed description of the scenario and steps in which you reproduced the problem, such as the detailed parameters of each device
Ok, my setup is the following: 2x FullHD Monitor (this one: Amazon.de), one connected directly over HDMI, and the other one connected over an USB-C to HDMI cable.
As mentioned, when I flash the official Android 13 image (edge2-android-13-v241206.img), everything works fine and the resolution is properly set by default (I don"t have to go in the settings app, and force 1920x1080)
However, when building a 14 version, applying the patches mentioned above, the display connected over USB-C (DP) gets scrambled (Even the OSD is not properly rendered). The only way that I found until now to make it work, is to force the 1920x1080 resolution in the settings app: When doing so, I get a proper rendering.
