Mi Hackintosh keep changing the output resolution

Hi friends, I have a OpenCore Hackintosh of Big Sur 11.2.2 and it’s working perfectly well except for this small (but annoying) issue...

I have a 32” LED TV 1080p capable and I’m using that resolution on my setup, the thing is that out of nowhere my TV change the "Just Scan” option for "16:9” and with this I lose image and audio many times. How can I stop this???
