_jis_Thank you very much!
I tested it as promised. It behaves the same way you described it and it is logical because we have a different aspect ratio than television. I completely solved the problem by installing this app:
This app REQUIRES elevated permissions, granted via root access or adb shell commands.
I used adb because I don't use root. In Tasker, I programmed a toggle widget on 9 lines using this app as a plugin. Switches the resolution to 1920x1080 on the first touch, returns to the original 2340x1080 on the second touch. It works perfectly.
Thanks for your inquiry, it gave me an impulse to solve it.
