I just changed my screen to the black background one and I had to adjust the contrast with STOP + WHEEL which is fine but when I turn it off then back on, it doesn't save the contrast setting. I tried holding MAIN when powering off but that doesn't work.

Is there another way? I'm using JJOSXL 3.52.

Thanks.
