UHD BD should be region free.
BD package shows its multi-region disk (ABC), unfortunately disk itself shows region A (America) while i reside in region B (Europe).
Both of my BluRay drives are multi-region, but PowerDVD does not allow me to set this. I can choose only one of those, and perform that change only 5x.
Back when CRT TVs were a thing, regions had importance, because you could not properly display PAL on NTSC system and vice-versa.
Now BluRays are all HD (1920x1080, 8bit Color, Bt 709, SDR), so the region requirement no longer makes any sense + my hardware should not have trouble with it.
In my collection is just one another disk which specifically requires Region B/C and enforces it through protection and its Fight Club.
Most bluray disks i own are either multiregion or do not enforce the region regardless of package information.
Is there any way how to set PowerDVD to multiregion?
