DPP4 does not recognize my HD display?

[LBChappuis]

Just got my EOS R8. I enabled HD PQ to use HIF files. Problem is when I try to edit the HIF files in DPP4: I cannot get it to recognize my display as an HD display

I am running DPP4 on a Mac Mini M1, with an Asus PA329C monitor (HD600 certified), with the HD display enabled in my setting. The display shows it working in HD_PQRec2020, but DPP4 insists in displaying the files "as converted to SDR". What am I missing?

It sounds like you may have a hardware compatibility issue.  The miniature Windows PC boxes have hardware compatibility issues, too.
