I am on Big Sur with OC 0.6.3.
I have a MSI 8GB RX580 GPU connected via HDMI to a Samsung 4K HDR TV. The HDR works great in Big Sur. On the TV I have to enable "Input Signal Plus" to get the HDR to work.
The problem is if I turn the TV off and on, there is no signal. The only fix is to restart the hackintosh, or to remote in and switch from 60Hz to 50Hz, this is force the signal to start.
If I use a DisplayPort to HDMI cable, the problem goes away, except that HDR no longer works.
I have tried forcing the Orinoco framebuffer, but the problem persists.
I have all sleep disabled and use Amphetamine.app to stay awake.
I would appreciate any help in sorting this out!
thanks
