hello I am a new VIM3 Pro user and installed Coreelec on my own to it.
SDR to HDR option was always active instead deactivated setting.
directly with first Khadas Boot logo and then with coreelec… always HDR.
So I formatted the EMMC and installed via USB-Burning-Tool VIM3_Pie_V210527 Android.
There was the SDR to HDR setting activated. I deactivated it and rebooted. But still HDR was active.
So please, how can I deactivate the SDR to HDR feature??? And how can I set it off in coreelec on EMMC??? I only wish HDR on HDR content.
Sorry to be able to deal with HDR problem now. you can try to enter the following command on the uboot command line
kvim3#setenv hdr_policy 1
then reboot your device to check if deactivate the SDR to HDR feature
