HDR output on MacBook Air M1
I have a MacBook Air M1 2020.
According to this page, it does not support output of HDR signal on a DisplayPort connection.
However, when I hook up my MacBook to my Targus Thunderbolt 3 dock, which is in turn connected via DisplayPort to my HDR monitor, I see the option to enable HDR in System Settings.
Is Apple's documentation incorrect? Or is the dock somehow 'fooling' the monitor into think it's receiving an HDR signal?
MacBook Air 13″, macOS 11.2
