If you cabled the HDMI to a USB-C interface, how much (if any) power would be available? Thanks

I can't find anything about LU28R550UQPXEN anywhere on the Internet. Here, too, they only talk about the LU28R550UQXZG. However, I am interested in the Adobe RGB values. I would like to verify this with an official statement from Samsung. Can you say something about this?

Hello,
Thank you for your enquiry.
The Samsung UHD monitor LU28R554UQRXZG comes with a pure HDMI cable, i.e. HDMI to HDMI.
Kind regards from Schwalbach
